For your specific use case, I’d recommend OBS Studio.

• Picture-in-picture webcam: You can add your webcam as a Video Capture Source and resize/reposition it anywhere over your screen recording. OBS Studio
• Green screen/chroma key: OBS has a built-in Chroma Key filter, so you can remove a physical green-screen background directly while recording. OBS Studio
• Flexible layouts: You can create reusable scenes—for example, full-screen product demo + small circular webcam, or a larger presenter view.
• Free: It's a particularly good choice if you want control without paying for a video-demo subscription.

If you prioritize simplicity

Loom is easier to get started with and is excellent for quick product demos: it records screen + camera simultaneously and supports a picture-in-picture camera bubble. Loom Loom Its virtual-background functionality is available, but Loom doesn't provide the same granular chroma-key workflow as OBS. Atlassian Support

loom.com

My pick: OBS Studio if the green-screen effect is an important requirement; Loom if speed and easy sharing matter more than production control.

For your specific requirements, I’d recommend OBS Studio.

obsproject.com

It fits particularly well because it supports:

• Picture-in-picture webcam — place your webcam anywhere over the product/demo screen.
• Chroma key / green screen — OBS has a built-in Chroma Key filter with control over the keying parameters.
• Flexible layouts — combine screen capture, webcam, browser windows, images, text, and other sources into custom scenes. OBS Studio
• Scene switching — useful if you want one layout for your intro, another for the actual demo, and another for a closing screen.
• Free and open source — available on Windows, macOS, and Linux. OBS Studio

If you want something easier

Camtasia is worth considering if you don't want to spend time learning OBS. It supports screen + webcam picture-in-picture and video background removal while recording, along with a proper video editor for polishing the finished demo. TechSmith

techsmith.com

StreamYard is another option if you prefer a browser-based workflow. It supports screen + camera recording and green-screen functionality, with considerably less setup than OBS. StreamYard

streamyard.com

My pick:

• 🎬 OBS → maximum control and true chroma-key compositing
• ✂️ Camtasia → easiest all-in-one recording + editing
• 🌐 StreamYard → easiest browser-based setup

If you're making polished SaaS/product demos for customers or marketing, I'd lean toward Camtasia or OBS, rather than Loom. Loom is excellent for quick screen + webcam recordings, but its green-screen capabilities are more limited. loom.com StreamYard

For your specific requirements—product demos + screen capture + picture-in-picture webcam + actual green-screen/chroma-key support—I’d look at these:

My recommendation: OBS Studio

obsproject.com is the strongest fit if chroma key is a must-have.

• Free and open source.
• Put your screen capture and webcam into separate scenes/layers.
• Built-in Chroma Key filter for a physical green screen.
• Very flexible PiP positioning, sizing, borders, overlays, logos, etc.
• Records locally, so you get a video file you can edit or upload anywhere.
• Works on Windows, macOS, and Linux.
• The tradeoff is that it takes more setup than tools like Loom. OBS is specifically noted for granular chroma-key controls. StreamYard StreamYard

If you want something easier: StreamYard

streamyard.com is worth considering if you want a browser-based recording studio rather than configuring OBS.

It supports screen + camera recording and has a dedicated green-screen mode, with considerably less setup. StreamYard

If you're on Mac and care about polished demos: Screen Studio

screen.studio is excellent for polished SaaS/product demos: automatic zooms, smooth cursor movement, webcam overlay, audio cleanup, and attractive layouts. Screen Studio

However, I wouldn't choose it specifically for a green-screen workflow. Its camera features focus more on background replacement/portrait effects than the granular chroma-key workflow you get with OBS. Screen Studio

Bottom line:

• 🎬 Green screen/chroma key is essential → OBS Studio
• ⚡ Easy browser-based recording → StreamYard
• ✨ Mac + polished product demos → Screen Studio

If you tell me whether you're on Windows or Mac, I can narrow this down to the best 2–3 options and compare PiP, green screen, editing, captions, 4K, and pricing.

Quick recommendation

For most product managers, founders, or SaaS teams, I’d choose Camtasia for repeatable polished demos, or OBS Studio + a good webcam + green screen if you want a studio-like setup with maximum control. edtick.com TechSmith

My pick: techsmith.com

For product demos with a webcam in picture-in-picture + a physical green screen, Camtasia is probably the best fit.

• Picture-in-picture: Record your screen and webcam simultaneously, then position/resize the webcam independently. TechSmith TechSmith Support
• Chroma key: It has a built-in “Remove a Color” effect specifically for green-screen backgrounds. TechSmith
• Editing: You get a proper multitrack editor, so you can add callouts, zooms, cursor effects, captions, transitions, etc. TechSmith
• Windows + Mac: Good choice if your team isn't exclusively on one platform.

If you want something more lightweight

• OBS Studio — best free option if you don't mind a more technical setup. It supports webcam overlays and chroma-key compositing, but you'll be doing more configuration yourself. Screenify Studio
• Screen Studio — best for polished Mac product demos with very little editing effort, but its camera features are more focused on background effects than traditional green-screen/chroma-key workflows. Screen Studio
• ScreenPal — worth considering if green-screen editing is particularly important; it explicitly supports webcam recording with chroma key and background replacement. ScreenPal

Bottom line: If your workflow is “record SaaS/product UI + put me in the corner over a green-screen background + edit it into a polished demo,” I'd choose Camtasia. If you want free + maximum control, choose OBS Studio.

If green-screen/chroma key + picture-in-picture webcam are must-haves, my top recommendation is OBS Studio.

• obsproject.com — Best overall for control and flexibility. It’s free, lets you compose your screen, webcam, images, text, and other sources into scenes, and its webcam source supports resizing/repositioning plus a Chroma Key filter for green screens. OBS Studio Zapier
• Camtasia — Best if you want easier editing afterward. It supports screen + webcam picture-in-picture and has green-screen capabilities, while also giving you a full timeline editor for callouts, animations, zooms, etc. TechSmith EdTick
• StreamYard — Best if you want simplicity. Its browser-based studio supports screen + camera recording and green-screen backgrounds without the more technical OBS setup. StreamYard

My pick for product demos

OBS Studio if you're comfortable spending ~15–30 minutes setting up your scene once. You can create a layout like:

[Product screen — full frame]
[Your green-screened webcam — small corner overlay]

Then record the finished composition directly, rather than having to edit the webcam into the demo afterward.

If you tell me Mac or Windows and whether you want polished marketing demos vs. quick sales demos, I can narrow it down to the best 2–3 tools for your workflow.

For your exact use case, I’d recommend FlowCapture.

chromewebstore.google.com

Why it fits

• Screen + webcam picture-in-picture — your face can sit over the product UI.
• Green-screen background removal — it specifically supports webcam green-screen compositing. Chrome Web Store
• Built for product demos — capture a browser tab, app window, desktop, or selected region.
• Up to 4K / 60 fps recording.
• Runs locally — recording, editing, background removal, and export happen on your device rather than uploading the recording to a cloud service. Chrome Web Store
• Includes demo-friendly features such as cursor effects, smooth zooms, drawing, and trimming.

Two alternatives

StreamYard is a better choice if you want a polished, presenter-focused browser studio. It supports screen + camera recording and green-screen backgrounds without much setup. StreamYard

streamyard.com

OBS Studio is the best choice if you want maximum control over chroma keying and scene composition. It's more complicated, but you can build essentially any product-demo layout you want. A recent comparison specifically notes its more precise chroma-key controls. StreamYard

obsproject.com

My pick: FlowCapture for quick SaaS/product demos; OBS if you're aiming for a highly polished, repeatable production setup.

For recording product demos with screen capture + picture-in-picture webcam + green-screen/chroma key, these are the strongest options:

1. OBS Studio — Best overall if you want maximum control (free)

obsproject.com

Best for: polished SaaS demos, live demos, technical walkthroughs, YouTube-style product videos.

Pros:

• ✅ Screen capture + webcam overlay (picture-in-picture)
• ✅ Built-in Chroma Key filter for green screens

• ✅ Free and no watermark
• ✅ Works with multiple cameras, microphones, and layouts

Cons:

• ❌ Requires some setup time
• ❌ No built-in video editor (you usually edit afterward)

OBS is often the best choice if you want a “mini production studio” setup. YouTubePlays EdTick

2. Camtasia — Best for professional business demos

techsmith.com

Best for: sales demos, onboarding videos, training materials, customer education.

Pros:

• ✅ Screen + webcam recording
• ✅ Picture-in-picture layouts
• ✅ Green-screen effects
• ✅ Built-in editor for trimming, zooming, callouts, captions, cursor effects
• ✅ Easier workflow than OBS

Cons:

• ❌ Paid software
• ❌ Less flexible for live production than OBS

Camtasia is a strong fit if you want to record, edit, and publish from one app rather than assemble a workflow. TechSmith TechSmith

3. ScreenFlow — Best Mac option

telestream.net

Best for: Mac-based product marketers and creators.

Pros:

• ✅ Excellent screen recording quality
• ✅ Webcam overlays
• ✅ Timeline editing built in
• ✅ Smooth animations and callouts

StreamYard

My recommendation by use case

For most software product demos, I’d choose:

• OBS Studio if you’re comfortable editing separately.
• Camtasia if you want a finished marketing/training video with minimal post-production. EdTick

A typical high-quality setup would be:

• 1080p webcam
• USB microphone
• green screen behind presenter
• OBS scene with webcam keyed out and placed in a corner
• separate “full presenter” and “screen demo” scenes for transitions.

For your exact requirements, I’d recommend Camtasia.

• Screen + webcam: Records your product demo with your webcam as picture-in-picture, and you can reposition/resize the webcam footage afterward. TechSmith TechSmith Support
• Green screen/chroma key: Camtasia is much better suited to a proper green-screen workflow than lightweight demo recorders because you can apply video effects and edit the webcam footage after recording.
• Product-demo editing: You get a full timeline editor, so you can add callouts, zooms, annotations, transitions, and clean up mistakes rather than having to re-record.
• Camera flexibility: It supports built-in webcams, USB cameras, virtual cameras, and capture devices. TechSmith Support

techsmith.com

If you want something simpler

Loom is excellent for quick product demos: it supports simultaneous screen + camera recording and a camera-bubble/picture-in-picture presentation. Loom Atlassian Support However, I wouldn't choose Loom if chroma key is a hard requirement—its current virtual-background feature supports presets, blur, and solid colors rather than a true custom green-screen/chroma-key workflow. Atlassian Support

Bottom line:
Camtasia = best fit for polished product demos + webcam PiP + green screen.
Loom = best if speed and easy sharing matter more than green-screen production.

If picture-in-picture webcam + true green-screen/chroma-key support are must-haves, I’d recommend OBS Studio.

• Best overall: OBS Studio — free, open source, and available on Windows, macOS, and Linux. You can put your webcam anywhere over the product demo, resize it, and apply the built-in Chroma Key filter to remove a physical green screen. OBS Studio OBS Studio
• Best for polished/easy editing: Camtasia — combines screen + webcam recording with a full video editor, including picture-in-picture and green-screen capabilities. It’s considerably easier for producing a finished demo, but it’s paid. TechSmith EdTick
• Best lightweight browser option: FlowCapture — specifically geared toward product demos, with screen recording, webcam PiP, green-screen background removal, trimming, and export, all processed locally in the browser. Chrome Web Store

My pick

Choose OBS if you care most about control and green-screen quality. Its scene system lets you build a reusable "Product Demo" layout with your screen capture, webcam, microphone, logo, and background, then record repeatedly. The chroma-key controls include similarity, smoothness, and spill reduction. OBS Studio

Choose Camtasia if you want to record → quickly edit → export without learning a production setup.

If you tell me whether you're on Windows or Mac, I can recommend the best option specifically for your workflow and give you a simple setup for the webcam + green screen.

My recommendation: OBS Studio

For your specific requirements—product demos + screen recording + picture-in-picture webcam + real-time green-screen/chroma key—I'd pick OBS Studio.

• Webcam PiP: Put your webcam over the product/demo screen and resize/reposition it freely.
• Chroma key: Built-in chroma-key filtering lets you remove a green-screen background.
• Scene control: You can create different layouts—for example, full-screen product demo, webcam + product, or webcam-only—and switch between them.
• Recording quality: Excellent control over resolution, frame rate, encoder, bitrate, audio sources, and output.
• Cost: Free and open source. Recent comparisons continue to rate it as the strongest option for advanced recording control. VidioPics VidioPics

obsproject.com

If you want easier editing

I'd consider Camtasia instead. It's better if your workflow is:

record → edit mistakes → add zooms/callouts → polish → export

rather than configuring a recording setup. Camtasia and ScreenFlow both provide separate screen/camera/audio tracks and a proper timeline editor. Borumi

techsmith.com

Bottom line:
OBS = best for live PiP + green screen + maximum control.
Camtasia = best for easy, polished product-demo editing afterward.
Screen Studio = worth considering on Mac if you prioritize beautiful, low-effort screen demos, but I'd choose OBS when actual chroma-key control is a hard requirement. screencharm.com rekort.app

My recommendation: obsproject.com

If picture-in-picture webcam + real chroma-key/green-screen support are must-haves, OBS Studio is the strongest choice.

• Webcam PIP: Add your camera as a source and position/resize it anywhere over your screen capture.
• Green screen: Its Chroma Key filter gives you control over similarity, smoothness, spill reduction, and other keying parameters. StreamYard
• Scenes: You can create different layouts—for example, full-screen product demo, webcam + screen, or presenter over a product UI.
• Free: Open source, with versions for Windows, macOS, and Linux. StreamYard
• Downside: It's more technical than tools like Loom.

If you want something easier

Camtasia is probably the better choice if you're making polished product demos rather than live productions. It records your screen and webcam simultaneously, then lets you reposition, resize, and layer the webcam footage during editing. TechSmith

Loom is excellent for quick product walkthroughs with a webcam bubble, but I wouldn't choose it if actual green-screen compositing is important. Its virtual-background functionality is more limited. Loom StreamYard

Bottom line: I'd pick OBS Studio if the green screen is a core requirement; Camtasia if you want the easiest path to professional-looking edited product demos.

If you tell me Mac or Windows and whether you want live recording vs. editing afterward, I can narrow it down to the best 1–2 options.

For your specific combination—product-demo screen recording + webcam picture-in-picture + real chroma-key/green-screen support—I’d recommend OBS Studio.

🥇 Best overall: OBS Studio

OBS Studio

It’s free and gives you considerably more control than typical screen-recording apps:

• Screen + webcam simultaneously with the webcam positioned anywhere on the screen.
• Chroma Key filter for your green screen, with adjustable similarity, smoothness, spill reduction, etc.
• Multiple scenes/layouts, so you can switch between full-screen product views, presenter + product, webcam-only, etc.
• Records locally, so you aren't dependent on an online service.
• Works on Windows, macOS, and Linux.
• Excellent if you want the finished demo to look like a polished presentation rather than a simple webcam bubble.

Current 2026 comparisons continue to identify OBS as one of the strongest choices specifically for real-time green-screen/chroma-key workflows. streamyard.com

Easier alternative: Descript

Descript

If you care more about easy editing after recording than live production control, I'd look at Descript. It can record your screen and webcam together and has a Green Screen feature for removing/replacing your background. www.descript.com

My recommendation

If you're doing polished SaaS/product demos regularly, I'd choose OBS. Set up a scene with your screen as the background and your keyed webcam as a foreground source, then record at 1080p/30 or 60 fps.

If you tell me Mac or Windows, I can also recommend the easiest OBS setup (including the exact chroma-key settings and webcam placement) for product demos.

If picture-in-picture webcam + actual chroma-key/green-screen support are must-haves, I’d shortlist these:

1. OBS Studio — best free/flexible option

• Free and cross-platform.
• Excellent webcam picture-in-picture.
• Built-in Chroma Key filter gives you detailed green-screen control.
• You can create a polished scene with your product screen full-frame and your webcam keyed over it.
• Downside: more technical setup, and you’ll probably want a separate editor afterward. Zapier StreamYard
• ScreenFlow — best if you're on Mac

• Designed specifically around screen recording + camera + editing.
• Supports picture-in-picture and chroma key.
• You can reposition/resize your webcam after recording, rather than committing to the layout during capture.
• Particularly nice for polished product demos and tutorials. Telestream Borumi
• Camtasia — best all-in-one editor

• Windows + Mac.
• Strong screen/webcam recording workflow with a substantial built-in editor.
• Better choice than OBS if you want to record a demo and then quickly turn it into a polished marketing/tutorial video without jumping between apps. TechRadar Zapier

My pick

For professional product demos, I'd choose ScreenFlow on Mac or OBS Studio on Windows.

If you want something extremely simple specifically for browser/SaaS demos, there's also FlowCapture: it combines screen recording, webcam PiP, and offline green-screen background removal/chroma key, plus demo-oriented features such as click-to-zoom and annotations. Chrome Web Store

If you tell me Mac or Windows and whether you want live recording with the green screen already removed vs. editing it afterward, I can narrow it down to the best 1–2 tools.

For your exact requirements—product demos + screen recording + picture-in-picture webcam + real green-screen/chroma-key support—I’d recommend OBS Studio if you’re comfortable with a little setup.

Best options

• obsproject.com — Best overall for flexibility

• Free and cross-platform.
• Lets you build a scene with your product screen plus a webcam overlay.
• Has a proper Chroma Key filter, so you can remove a physical green screen and place yourself over the product UI.
• Extremely customizable: webcam position, borders, shadows, backgrounds, multiple scenes, etc.
• Downside: takes more setup than tools like Loom. StreamYard stepvideo
• streamyard.com — Best if you want simplicity

• Browser-based recording with screen + camera layouts.
• Supports a dedicated green-screen mode.
• Much easier to get a polished presenter-over-screen look without learning OBS. StreamYard StreamYard
• flowcapture.app — Worth a look for product demos

• Specifically geared toward product demos and walkthroughs.
• Offers webcam picture-in-picture with offline green-screen/chroma-key background removal, plus annotations, zooms, auto-scroll, and local MP4 export. Chrome Web Store
• loom.com — Best for quick/simple demos

• Excellent screen + webcam picture-in-picture and very easy sharing.
• But I wouldn't choose it if true green-screen compositing is a core requirement; its background features aren't equivalent to OBS-style chroma key. Loom StreamYard

My pick

If you want the highest-quality, reusable setup: OBS Studio.

You can create a scene like:

[Product demo fills screen] + [your webcam cut out with chroma key] → [bottom-right/left]

Then save that scene and use it for every demo.

If you tell me Mac or Windows and whether you want a polished “YouTuber” look or a clean SaaS/product-demo look, I can recommend the best setup and exact settings.

My recommendation: techsmith.com

For your specific requirements, Camtasia is probably the best all-around choice. It supports:

• Screen recording + webcam picture-in-picture
• Green-screen/chroma-key effects
• A full timeline editor for trimming, zooming, callouts, animations, etc.
• Windows and Mac
• A relatively straightforward workflow compared with more production-oriented tools. EdTick Zapier

If you want free: OBS Studio

obsproject.com is my pick if chroma-key control is the priority. It's free, supports multiple scenes/sources, webcam PiP, and has granular chroma-key controls. The tradeoff is that it takes more setup and doesn't have Camtasia's built-in editing workflow. StreamYard Zapier

One I'd avoid for this particular requirement: Screen Studio

screen.studio is excellent for polished Mac product demos—it has superb automatic zooms, cursor effects, and webcam overlays. Screen Studio Screen Studio But it doesn't currently appear to support true chroma-key green-screen compositing; its own feature-request board still lists chroma key as a requested feature. hub.screen.studio

Bottom line:
Camtasia → easiest polished product-demo workflow with green screen.
OBS → best if you want maximum control and zero cost.
Screen Studio → best-looking/easiest Mac demos, but not if green-screen chroma key is essential.

For product demos with screen capture + picture-in-picture webcam + green screen/chroma key, I’d shortlist these:

🥇 Best overall: OBS Studio (free)

obsproject.com

Best for: polished demos, SaaS walkthroughs, webinars, YouTube-style product videos.

Why it fits:

• ✅ Screen recording

• ✅ Multiple scenes (e.g., intro with full camera → product demo → closing slide)
• ✅ Custom layouts, overlays, branding
• ✅ Free and cross-platform

Tradeoff:

• More setup than beginner tools. You’ll need to configure scenes, sources, audio, and lighting. StreamYard

• Scene 2: Screen capture + small keyed webcam window
• Scene 3: Product close-up + callouts

🥈 Easiest polished workflow: Camtasia

streamyard.com

Best for: customer demos, webinars, marketing recordings.

Why it fits:

• ✅ Browser-based
• ✅ Screen sharing
• ✅ Camera overlays
• ✅ Green screen support
• ✅ Branded layouts and multiple presenters

Tradeoff:

• Less control than OBS for advanced compositing. StreamYard

Quick comparison

loom.com is great for quick screen + webcam recordings, but it is better suited to lightweight async communication than fully produced green-screen demos. StreamYard

My pick:

• Need free + professional: OBS Studio
• Need polished sales/training videos quickly: Camtasia
• Need to record with teammates/customers remotely: StreamYard

For a typical software product demo, I’d choose OBS + a good webcam + green screen, then edit the final cut in a video editor if needed.

If green-screen chroma key is a hard requirement, my top recommendation is obsproject.com.

• Picture-in-picture: Add your webcam as a Video Capture Source, then resize and position it anywhere over your screen capture. OBS Studio
• Green screen: OBS has a built-in Chroma Key filter specifically for removing a green-screen background. OBS Studio
• Product demos: You can combine your app/window capture, webcam, logos, text, backgrounds, and multiple scenes, giving you much more control over the final composition. OBS Studio
• Cost: Free and open source. OBS Studio
• Downside: It's more technical than tools like Loom, so there's a little more setup.

If you want something simpler

FlowCapture is worth a look. It specifically targets product demos and offers webcam picture-in-picture plus offline green-screen/chroma-key removal, along with screen recording and a built-in editor. Chrome Web Store

chromewebstore.google.com

My pick:
OBS if you want maximum control and professional-looking demos. FlowCapture if you want the easiest product-demo workflow with chroma key built in.

Loom and Riverside are excellent for quick screen + webcam demos, but based on the features documented on their current pages, I'd choose OBS/FlowCapture when actual green-screen chroma key is important. Loom riverside.com

My recommendation: OBS Studio

obsproject.com is the best fit if green-screen/chroma-key support is a must.

• Picture-in-picture webcam: Add your webcam as a separate source and position/resize it anywhere over the product demo.
• Chroma key: Built-in Chroma Key filter lets you remove your green-screen background with adjustable similarity, smoothness, and spill reduction.
• Flexible layouts: You can create different scenes—for example, full-screen product demo, demo + small facecam, or full-screen presenter.
• Free: It's open-source and available for Windows, macOS, and Linux. Zapier StreamYard
• Downside: It's more technical to set up than dedicated demo-recording apps. Zapier

If you want something easier

Camtasia is my pick for a polished product-demo workflow. It records screen and camera on separate tracks, supports picture-in-picture, and has a Remove a Color (chroma key) effect for green-screen footage. TechSmith

techsmith.com

Bottom line: Choose OBS Studio if you want maximum control and a genuinely good chroma-key setup. Choose Camtasia if you want to record a demo and then quickly turn it into a polished marketing/tutorial video. StreamYard is another good choice if you want a browser-based workflow. StreamYard StreamYard

If you tell me Mac or Windows and whether you want live chroma key while recording or the ability to remove the green screen afterward, I can narrow it down to the best setup.

My pick: descript.com

For your specific requirements, Descript is probably the best fit. It supports:

• Screen + webcam recording with picture-in-picture layouts. Descript
• Actual chroma key if you're recording against a physical green screen. Descript distinguishes this from its AI background-removal effect. Descript
• AI background removal if you don't want to use a physical green screen.
• Post-recording editing, including transcript-based cuts, captions, audio cleanup, and branded layouts. Descript
• Mac and Windows support, plus browser recording. Descript

That makes it particularly good for polished SaaS/product demos where your webcam appears over the product UI.

Runner-up: tella.com

Tella is excellent if your priority is fast, attractive product-demo recording. It records screen and camera as separate tracks, supports multiple layouts, up to 4K, and has Mac/Windows/web versions. Tella

However, I'd choose Descript if chroma key is a hard requirement. Tella is more focused on layouts/custom backgrounds and rapid demo production, while Descript explicitly supports Chroma Key. Descript

Bottom line: Descript for green-screen + PiP + serious editing; Tella if you care more about speed and a streamlined demo-recording workflow.

If green-screen/chroma key is a hard requirement, my top recommendation is OBS Studio.

🥇 Best overall: OBS Studio

obsproject.com

It gives you exactly the setup you're describing:

• Screen recording + webcam simultaneously
• Picture-in-picture: position, resize, crop, and shape your webcam anywhere on the screen
• True chroma key: OBS has a built-in Chroma Key filter specifically for green screens. OBS Studio
• Multiple scenes/layouts, so you can switch between full-screen product views, webcam + product, title cards, etc.
• Free and available on Windows, macOS, and Linux
• Excellent recording quality and control over resolution, FPS, audio, and bitrate

Downside: it's more of a production studio than a simple product-demo recorder. You'll spend some time configuring scenes and sources.

🥈 Easiest option: FlowCapture

chromewebstore.google.com

This is interesting if you want something much simpler. It specifically supports webcam picture-in-picture plus offline green-screen background removal/chroma key, along with screen recording and product-demo-oriented features such as cursor zooms and annotations. Chrome Web Store

I'd choose this if your workflow is basically:

Open product → hit record → show product + yourself → stop → export.

🥉 Another simple option: ScreenPal

screenpal.com

ScreenPal has explicit green-screen support: record the webcam against a solid background, select the color to remove, adjust the settings, and replace it with another background. ScreenPal

My pick

One caveat: Screen Studio is excellent for polished product demos and webcam overlays, but its own feature-request page indicates that true chroma-key support has been a missing feature, so I wouldn't choose it for a physical green-screen workflow. hub.screen.studio

For your specific requirements, I'd start with OBS Studio. If you tell me whether you're on Mac or Windows, I can recommend the simplest setup and exact settings for a professional-looking product-demo recording.

If green-screen/chroma key + picture-in-picture webcam are both must-haves, I’d recommend FlowCapture.

• FlowCapture — Best fit for your exact requirements. It records your screen plus a webcam picture-in-picture overlay, with offline green-screen background removal (chroma key) built in. It also has click-to-zoom, cursor effects, drawing/annotation tools, and local MP4 export. Chrome Web Store
• ScreenPal — A good alternative if green-screen editing is the priority. It has a dedicated chroma-key workflow where you can select the background color and replace it with an image. ScreenPal
• Tella — Excellent for polished SaaS/product demos, with screen + camera recording, editable layouts, backgrounds, clips, and 4K export. However, Tella doesn't have built-in virtual-background/chroma-key support, so you'd need another tool for that part. Tella Tella
• OBS Studio — Best if you want maximum control and don't mind a more technical setup. It's particularly strong for custom scenes, webcam positioning, and advanced chroma-key configuration. StreamYard

My pick

FlowCapture if you want something purpose-built for product demos and want to hit Record → screen + webcam → green-screen removal → export without building a complicated scene.

If you're on Mac and care more about exceptionally polished screen-demo animations than chroma key, Screen Studio is also worth considering; it specializes in product demos with automatic zooms and smooth cursor animations. screen.studio screen.studio

chromewebstore.google.com
screen.studio
tella.tv
screenpal.com

If green-screen/chroma key is a hard requirement, I’d recommend FlowCapture.

• FlowCapture — Built specifically for product demos and walkthroughs. It supports webcam picture-in-picture plus offline green-screen background removal (chroma key), screen/app/window capture, up to 4K/60 fps, annotations, zooms, and local MP4 export. Chrome Web Store
• Tella — Better if you want a more polished editing/sharing workflow. It supports screen + camera, customizable picture-in-picture layouts, zooms, subtitles, and editing; it runs on Mac, Windows, and the web. Tella Tella
• Loom — Excellent for quick product demos and team sharing, with screen + camera picture-in-picture, but I wouldn't choose it specifically for chroma-key green screen. Loom Loom
• Screen Studio — My pick for gorgeous, cinematic Mac product demos, particularly because of its automatic zooms and polished presentation, but its strength isn't green-screen compositing. screen.studio preview.screen.studio

Bottom line:
FlowCapture if green screen is essential → Tella if you want the best all-around demo creation/editing experience → Screen Studio if you're on Mac and visual polish matters most.

For your specific requirements—product demos + webcam picture-in-picture + actual chroma-key green screen—I’d recommend FlowCapture first.

🥇 FlowCapture — best fit

FlowCapture

It’s unusually well matched to what you’re asking for:

• Screen + webcam picture-in-picture
• Built-in green-screen/chroma-key background removal
• Records browser tabs, apps, desktop, or selected regions
• Up to 4K / 60 fps
• Built-in zooms, cursor effects, annotations, and smooth scrolling
• Local processing/export, rather than requiring everything to go through the cloud
• Specifically designed around product demos, tutorials, onboarding, and walkthroughs. chromewebstore.google.com

Why I'd pick it: you don't have to assemble a recording stack just to get a presenter cut out over your product UI.

Other good options

OBS Studio — best if you want maximum control. It has excellent chroma-key controls, arbitrary scene layouts, webcam PiP, overlays, transitions, etc. The tradeoff is that it's much more of a production tool than a purpose-built product-demo recorder. Riverside explicitly supports using OBS as a virtual camera for overlays, filters, and backgrounds. support.riverside.com

StreamYard — best for easy browser-based recording. It supports screen + camera recording and green-screen virtual backgrounds, with considerably less setup than OBS. streamyard.com

Riverside — strong if you also want high-quality talking-head recording, guests, separate tracks, and editing. Its screen recorder supports movable webcam overlays, and its editor has PiP layouts. riverside.fm

Screen Studio — my pick if you're on Mac and care primarily about making beautiful SaaS/product demos quickly. Its automatic cursor movement and zooms are excellent, but I wouldn't choose it specifically for green-screen work. screen.studio

My ranking for your use case

Bottom line: Start with FlowCapture if green-screen webcam compositing is a hard requirement. If you want professional broadcast-level control, use OBS instead.

For your exact requirements—product demos + screen recording + webcam picture-in-picture + green-screen/chroma key—I’d recommend FlowCapture.

• FlowCapture — Best fit if you want something simple and demo-focused. It records your screen and webcam together, supports webcam PiP with offline green-screen/chroma-key background removal, and includes demo-friendly features like cursor effects, click-to-zoom, annotations, and voice enhancement. It runs as a Chrome extension. chromewebstore.google.com
• OBS Studio — Best if you want maximum control and don't mind a little setup. You can create a scene with your product screen, webcam PiP, and a chroma-key filter, then customize virtually everything. It's particularly good if you're producing polished marketing demos rather than quick recordings.
• ScreenPal — A good middle ground if you want traditional screen recording plus straightforward green-screen/chroma-key editing. screenpal.com
• FlowRec — Interesting if your demos are primarily websites and you want yourself composited directly over the page rather than in a small corner. Its green-screen effect happens live, with no physical green screen required, but it's currently iPhone/iPad focused. flowrec.app

My pick:
👉 FlowCapture for fast SaaS/product demos.
👉 OBS Studio if you want professional scene composition and the ability to fine-tune the green screen.

I wouldn't choose Screen Studio specifically for this requirement: it's excellent for polished Mac product demos and automatic zooms, but its own feature-request page indicates chroma key/virtual backgrounds aren't currently a core feature. screen.studio

If you tell me Mac or Windows, I can narrow this down to the best 2–3 options and compare price, chroma-key quality, PiP controls, and editing features.

For your specific requirements, I’d recommend OBS Studio if you want maximum control, or Camtasia if you want a polished product-demo workflow with less setup.

My picks

1. OBS Studio — best for green screen + flexibility

• Free and available on Windows, macOS, and Linux.
• Supports webcam picture-in-picture through scenes/sources.
• Built-in chroma key filter for a physical green screen.
• Lets you position, resize, crop, and layer your webcam over the product demo.
• Excellent if you want to build a reusable demo layout.
• Downside: the interface is more technical than dedicated demo tools.

2. Camtasia — best all-in-one product-demo editor

• Records your screen and webcam and gives you a full video-editing timeline afterward.
• Better choice if you want to add callouts, zooms, cursor effects, transitions, titles, etc.
• Recent comparisons continue to position it as particularly strong for heavily edited demos. getrapidemo.com
• I'd choose this if the final video needs to look like a polished marketing/tutorial asset rather than a quick screen recording.

3. Loom — best for speed, but not my pick for green-screen production

• Very easy screen + webcam recording and explicitly supports picture-in-picture product demos. www.loom.com
• Great for sending demos to prospects or teammates immediately.
• However, if physical green-screen/chroma-key control is a hard requirement, I'd use OBS or Camtasia instead.

What I'd choose

If you're specifically looking for “screen + my green-screened webcam composited over the product, with automatic zooms/cursor highlighting and minimal editing”, I can narrow this down to the best 2–3 dedicated product-demo tools rather than general screen recorders.

For your specific needs, I’d recommend Descript.

Why it fits:

• Screen + webcam simultaneously with picture-in-picture layouts. www.descript.comwww.staging.descript.com
• Green-screen/chroma key support — it specifically supports Chroma Key for footage shot against a physical green screen. help.descript.com
• Strong post-recording editing, including transcript-based cuts, audio cleanup, captions, and background replacement. www.descript.comwww.staging.descript.com
• Works on Mac and Windows, as well as in a browser. www.descript.comwww.staging.descript.com

Two alternatives

FlowCapture — worth considering if you want something more purpose-built for product demos. It offers screen recording, webcam PiP, and offline chroma-key background removal, plus demo-friendly zooms and annotations. chromewebstore.google.com

StreamYard — best if you want a polished, browser-based presenter experience. It supports screen-share layouts including PiP and a dedicated green-screen mode. streamyard.com

My pick: Descript for polished product demos where you'll edit afterward; FlowCapture if you want the simplest demo-focused workflow with green-screen support built in.

If picture-in-picture webcam + actual chroma-key/green-screen support are must-haves, I’d recommend FlowCapture.

My picks

Why FlowCapture stands out: it combines screen recording, webcam PiP, and offline green-screen background removal (chroma key) in one workflow. It also has product-demo-friendly features like click-to-zoom, cursor effects, drawing/annotation, and up-to-4K recording. chromewebstore.google.com

If you want maximum control and don't mind a more technical setup, OBS Studio is probably the strongest choice. You can create a scene with your product screen as the background, put your webcam over it, and apply a chroma-key filter to the camera. It's free and open source. www.screenify.studio

If you want easy editing after recording, I'd choose Camtasia. It supports removing a color/chroma key in the editor, so you can record your webcam and then refine the green-screen effect afterward. www.youtube.com

My recommendation:

• 🎯 Fastest/easiest: FlowCapture
• 🛠️ Most powerful/free: OBS Studio
• ✂️ Best all-in-one editing: Camtasia

If you're on Mac, I'd lean toward FlowCapture or Camtasia rather than OBS if your priority is making polished SaaS/product demos quickly.

If green-screen/chroma key is a hard requirement, I’d recommend FlowCapture first.

• FlowCapture — built specifically for screen/product demos, with webcam picture-in-picture + offline green-screen/chroma-key background removal. It can record browser tabs, apps, desktop, or regions, and exports locally. chromewebstore.google.com

FlowCapture

• OBS Studio — best if you want maximum control and free software. You can create a screen source, webcam source, resize the webcam into PiP, and apply a Chroma Key filter. The tradeoff is a steeper setup/learning curve.

• Camtasia — better if you want a full editing workflow after recording: screen + webcam, annotations, effects, etc. It's more of a video editor than a lightweight demo recorder.

• Screen Studio — excellent for polished Mac product demos, with automatic zooms and webcam recording, but native chroma-key isn't really its strength; you'd need a workaround/post-processing for green-screen footage. screen.studio

Screen Studio

My pick: FlowCapture if you want “record my app, put me in the corner, remove my green-screen background, and get on with the demo.” If you want sophisticated scene layouts and don't mind configuring things, OBS is the more powerful choice.

For your specific requirements—product demos + picture-in-picture webcam + green-screen/chroma key—I’d recommend Camtasia.

🥇 Best overall: Camtasia

TechSmith’s Camtasia is particularly well suited because it can:

• Record screen + webcam simultaneously
• Put the webcam in picture-in-picture and reposition/resize it during editing www.techsmith.com
• Apply a Remove a Color / chroma-key effect for a physical green screen www.techsmith.com
• Record screen, camera, and audio on separate tracks, giving you substantial editing flexibility www.techsmith.com
• Also use AI background removal, so you don't necessarily need a physical green screen www.techsmith.com

Other good choices

OBS Studio is the one I'd pick if you want maximum control over the green-screen effect and don't mind configuring scenes/sources yourself. Camtasia is much more convenient if you want to record and then quickly edit a polished product demo. streamyard.com

OBS Studio

One newer option worth looking at: FlowCapture specifically advertises webcam PiP with offline green-screen/chroma-key background removal, plus screen recording and product-demo-oriented editing. chromewebstore.google.com

FlowCapture

My pick: Camtasia if you're making professional SaaS/product demos regularly; OBS if you want free and highly configurable; FlowCapture if you want the quickest browser-based workflow.

For your exact requirements, I’d recommend OBS Studio if you’re okay with a little setup.

• Picture-in-picture webcam: Add your webcam as a Video Capture Source and resize/reposition it anywhere over the product demo. obsproject.comobsproject.com
• Green screen/chroma key: OBS has a dedicated Chroma Key filter with controls for similarity, smoothness, spill reduction, etc. obsproject.com
• Free: It’s free and open-source, with versions for Windows, macOS, and Linux. obsproject.com
• Flexible layouts: You can build scenes with your screen, webcam, logos, overlays, backgrounds, and multiple cameras.

OBS Studio

If you want something easier

Camtasia is my pick if you want to record and then polish the demo without learning OBS. It supports webcam recording, picture-in-picture, green-screen effects, annotations, zooms, and a full editing timeline. www.edtick.com

Camtasia

StreamYard is worth considering if you want the simplest browser-based workflow. It supports screen + camera recording and a built-in green-screen mode, though OBS gives you considerably more chroma-key control. streamyard.com

StreamYard

My ranking for product demos:

1. 🥇 OBS Studio — best control + green screen + free
2. 🥈 Camtasia — best if you want polished editing afterward
3. 🥉 StreamYard — easiest setup

If you're making SaaS/product demos for customers or marketing, I'd lean Camtasia for polished prerecorded videos and OBS for maximum control.

For your specific use case, I’d recommend Camtasia.

It’s particularly well suited to product demos because you can:

• 🖥️ Record your screen and webcam simultaneously, with the webcam as picture-in-picture.
• 🟢 Use a chroma-key / “Remove a Color” effect to key out a green-screen background. www.techsmith.com
• ✂️ Edit the recording afterward with a full timeline, rather than having to get the entire presentation right during recording.
• 🔎 Add zooms, callouts, annotations, cursor effects, captions, and other demo-friendly polish.
• 💻 Use it on both Windows and Mac. www.tella.com

If you want free: OBS Studio

OBS Studio is the best free alternative. It gives you much more control over the composition: screen capture + webcam + overlays + chroma key, with detailed keying controls. streamyard.com

The tradeoff is that OBS is more of a production studio than a simple product-demo recorder—you'll need to configure scenes and sources yourself, and it doesn't include Camtasia's built-in video editor. www.edtick.com

My pick

If you're making polished SaaS/product demos for customers or marketing, I'd choose Camtasia. If you want maximum control and zero software cost, choose OBS.

If you're on Mac, ScreenFlow is also an excellent option—it specifically supports both picture-in-picture and chroma key for software demonstrations. www.telestream.net

If picture-in-picture webcam + real green-screen/chroma-key support are must-haves, I’d recommend OBS Studio.

🥇 Best overall: OBS Studio

OBS Studio

• Free and open source
• Put your webcam anywhere over the product demo for true picture-in-picture.
• Built-in Chroma Key filter lets you remove a physical green screen and replace it with your own background. obsproject.comobsproject.com
• Works on Windows, macOS, and Linux. obsproject.comobsproject.com
• Extremely flexible: screen capture, webcam, microphone, multiple scenes, overlays, branding, etc.
• Downside: it takes more setup than tools like Loom or Screen Studio.

🥈 If you want something easier

FlowCapture is interesting if you primarily make browser-based product demos. It combines screen recording, webcam PiP, and offline green-screen/chroma-key background removal, with built-in editing and exports. obsproject.comobsproject.comchromewebstore.google.comscreen.studiohub.screen.studio

🥉 If you're on Mac and want polished demos

Screen Studio is excellent for beautiful product demos, with automatic zooms and polished cursor movement. screen.studio But I wouldn't choose it if actual green-screen chroma key is a requirement—its webcam/background features aren't as capable as OBS for that workflow. hub.screen.studio

My pick: OBS if green screen is non-negotiable; FlowCapture if you want the simplest product-demo workflow; Screen Studio if visual polish matters more than chroma key.

If you tell me Mac or Windows and whether you want live green-screen compositing or editing it afterward, I can narrow it down to the best 1–2 options.

For your exact requirements, I’d recommend StreamYard.

• Picture-in-picture webcam: Yes — designed around combining your camera with screen sharing.
• Green screen / chroma key: Yes. StreamYard supports green-screen backgrounds directly in its browser studio. streamyard.com
• Product demos: Good fit for presenter-led SaaS/product walkthroughs where you want your face visible alongside the product.
• Ease of use: Much simpler than a full production tool like OBS.
• Browser-based: You don't need a complicated recording/editing setup.

Two alternatives worth considering

OBS Studio — best if chroma-key control is the priority. It's free and gives you much more control over green-screen keying, webcam positioning, scenes, overlays, and recording. The tradeoff is considerably more setup. streamyard.com

Tella — best for polished product demos with minimal editing. It records screen and webcam separately, supports picture-in-picture/custom layouts, and lets you change the layout after recording. landingpage.tella.com However, if actual green-screen chroma key is essential rather than virtual backgrounds, I'd choose StreamYard or OBS instead.

My pick:
👉 StreamYard if you want “open it, record a professional demo, and be done.”
👉 OBS if you want maximum green-screen/compositing control.
👉 Tella if the green screen is secondary and you care most about making polished SaaS demos quickly.

If green-screen/chroma key is a hard requirement, my top recommendation is OBS Studio.

• OBS Studio — Best overall for your requirements. It’s free, records your screen and webcam simultaneously, lets you resize/reposition the webcam as a picture-in-picture layer, and has a built-in Chroma Key filter for removing a green screen. obsproject.comwww.edtick.com
• Camtasia — Best if you want easier editing. It combines screen recording, webcam picture-in-picture, green-screen removal, and a full video editor. It's much more beginner-friendly than OBS, but paid. obsproject.comwww.edtick.com
• StreamYard — Best for quick browser-based demos. It supports screen + camera layouts and green-screen recording without much setup. streamyard.com
• Screen Studio — Best for polished Mac product demos, particularly if you want automatic zooms, cursor effects, and attractive presentation. However, its camera features focus more on background effects than traditional manual chroma-key control, so I wouldn't choose it specifically for a physical green screen. screen.studio

My pick

OBS Studio if your priority is:

screen + webcam overlay + actual green-screen chroma key + maximum control + no subscription.

Camtasia if your priority is:

"I want it to be easy and I want to edit the demo afterward."

For a SaaS/product demo, I'd probably choose OBS → record → edit in Camtasia/DaVinci Resolve if you want a particularly polished result.

For recording product demos with screen capture + picture-in-picture webcam + green screen/chroma key, these are the strongest options depending on how polished you want the result to be:

My recommendations

Best overall for serious product demos:
→ OBS Studio
Use it if you want a “studio” setup:

• Screen capture layer
• Webcam layer over the demo
• Green-screen removal via chroma key filter
• Multiple layouts (intro, demo, closing slide)
• External mic/camera support

Best if you use a Mac and want less setup:
→ ScreenFlow
It is purpose-built for tutorials and product walkthroughs, with screen + camera recording, picture-in-picture editing, and chroma key support. www.telestream.net

Best for sales/marketing teams that need speed:
→ StreamYard or FlowCapture
You can get a polished presenter-on-screen look without learning a full production tool. chromewebstore.google.comstreamyard.com

A common high-quality setup is:

• 1080p webcam (or mirrorless camera)
• USB/XLR microphone
• OBS Studio
• Green screen or AI background removal
• Separate scene for intro → demo → call-to-action

If your demos are mostly SaaS/software walkthroughs, I’d lean toward OBS + a good mic for maximum quality, or ScreenFlow if you’re on Mac and want speed.

For your specific use case, I’d recommend Camtasia.

• Picture-in-picture webcam: You can record your screen and webcam simultaneously, then resize/reposition the webcam overlay. www.techsmith.com
• Green screen: Camtasia has a Remove a Color (chroma key) effect specifically for green-screen footage. www.techsmith.comobsproject.com
• Product-demo friendly: It records screen, camera, microphone, and system audio on separate tracks, which makes fixing mistakes and polishing demos much easier. www.techsmith.com
• Modern alternative to chroma key: It also has AI background removal, so you can remove your webcam background without an actual green screen. www.techsmith.com

Camtasia official site

If you want free

OBS Studio is the best free option. It supports webcam sources, picture-in-picture compositions, and a Chroma Key filter. The downside is that it’s much more hands-on and doesn't include Camtasia's built-in video editor. obsproject.com

My pick: Camtasia for polished SaaS/product demos; OBS if cost and maximum control matter more.

I wouldn't choose Screen Studio for this particular requirement: it's excellent for beautiful product demos on Mac, but its green-screen/chroma-key support has been a longstanding missing feature. screen.studio
