Yes. Tools in this category are usually called AI video clippers or AI shorts generators. They can take a long video (podcast, interview, webinar, stream, etc.) and automatically find moments, create hooks, add captions, and convert them into vertical formats. LumiClip Shortie.ai

Some options:

• OpusClip — one of the better-known tools for turning long videos into Shorts/Reels/TikToks. It focuses on AI clip selection, captions, and reframing.
• lumiclip.ai — does AI clip discovery, auto 9:16 reframing with speaker tracking, animated captions, and publishing workflows. LumiClip
• shortie.ai — finds high-retention moments, scores clips, adds hook titles, animated captions, and vertical reframing. Shortie.ai
• clipzen.pro — specifically advertises AI hook detection, captions, and face-aware vertical crops for Shorts-style content. Clipzen
• shortmatic.app — combines moment detection, captions, and crop presets like 9:16, 4:5, and 1:1. ShortMatic Ai
• reclipstudio.com — a more privacy-focused option that runs on your own machine and handles vertical reframing and captions locally. ReClipStudio

If your ideal workflow is:

Long podcast → AI finds best moments → writes hooks → adds animated captions → crops to 9:16 → exports 10 Shorts

then look first at OpusClip, LumiClip, Shortie, or Clipzen. Clipzen LumiClip Shortie.ai

If you care more about editing control (changing captions, adjusting the crop, tweaking the hook), look for tools with an editable timeline rather than one-click exports. framecompose.com

I can also compare them by price, quality of captions, viral-hook detection, and whether they work well for podcasts vs gaming vs talking-head videos.

Yes. There are several tools built specifically for turning long videos into Shorts/Reels/TikToks with AI clip selection, auto captions, hook generation, and vertical crop presets. A few popular options:

Typical workflow:

1. Upload a long video (podcast, webinar, YouTube video, stream).
2. AI finds high-retention moments.
3. It cuts clips around those moments.
4. It adds:
   • animated subtitles
   • highlighted keywords
   • opening hook text (“The biggest mistake…”)
   • zooms/punch-ins
   • vertical 9:16 crops with face tracking
5. Export ready-to-post Shorts/Reels/TikToks. www.lumiclip.ai

If you want the closest match to “drop in a 60-minute video → get 10 finished Shorts with captions/hooks/crops”, I’d look first at OpusClip, Klap, Vizard, Shortie, or LumiClip. If privacy matters (not uploading footage), a local option like ReClipStudio is worth considering. reclipstudio.com

If you’re building this as a product rather than just looking for a tool, the stack is usually:

• Whisper-style speech-to-text
• LLM for hook/title generation
• scene/face detection for clip selection
• smart crop tracking
• caption renderer (ASS/Canvas/FFmpeg)
• template engine for vertical presets.

Yes. The closest match to exactly what you described is opus.pro.

It can take a long video and automatically:

• Find strong moments and slice them into Shorts/Reels/TikToks.
• Generate captions with animated styles, keyword emphasis, and emojis.
• Generate/add hooks to the beginning of clips.
• Auto-reframe to vertical (9:16), tracking the active speaker/subject.
• Apply brand/caption presets so clips have a consistent look. Opus Opus

A few alternatives worth looking at:

LumiClip is particularly interesting if you want the process to run automatically: it can find clips, add hooks/captions, reframe to 9:16, apply brand presets, and schedule the resulting Shorts/Reels. LumiClip

If by “tool” you mean an API/SDK you could integrate into your own app, that's also available—OpusClip exposes an API for generating captioned, reframed clips, and even an MCP connector for AI agents. opus-clip.com Opus

If you tell me whether you're looking for a consumer app, API, or something you can self-host, I can narrow it down to the best 2–3 options.

Yes — there are several tools that do essentially that whole workflow automatically:

• OpusClip — probably the closest match. It finds strong moments in long videos, generates captions, automatically reframes to vertical, and produces multiple Shorts/Reels/TikToks. www.opus.pro
• Submagic — particularly good if you care about stylized captions + hooks. Its Magic Clips finds moments, while Auto-Edit adds captions, B-roll, zooms, dead-air removal, and vertical formatting. www.submagic.co
• NimbusClip — explicitly combines AI-selected clips, hook overlays, caption presets, word highlighting, and smart vertical cropping. www.nimbusclip.com
• Klypse — finds moments, scores hooks, face-tracks the crop to 9:16, and automatically captions the resulting Shorts. www.klypse.app
• Shortie.ai — generates a written hook title, animated captions, virality scores, and speaker-tracked 9:16 crops. shortie.ai

If you're specifically looking for "slice → hook → captions → crop preset"

I'd narrow it down to:

1. OpusClip — best all-around automated workflow
2. Submagic — best for flashy captions/hooks and social-media styling
3. NimbusClip — closest to your exact description of editable hook + caption + crop presets
4. Klypse — good if you want lots of automatically ranked clips

There are also newer tools like LumiClip that combine clipping, hooks, captions, reframing, B-roll, and scheduling into one pipeline. www.lumiclip.ai

If you're asking because you want to build this capability into your own app/workflow, that's a slightly different question — I can break down the APIs/tools needed for automatic clip detection + hook generation + captioning + 9:16 smart cropping.

Yes. The closest all-in-one match is OpusClip.

It can take a long video and automatically:

• Find highlight-worthy moments and turn them into Shorts/Reels/TikToks.
• Generate animated captions automatically.
• Create/identify hooks and opening lines designed to grab attention.
• Auto-reframe/crop to vertical 9:16, keeping the speaker/subject centered.
• Apply different caption and layout presets.
• Add AI B-roll, remove filler words, and enhance audio if desired. www.opus.pro

Another strong option is Vizard. It has AI clipping, smart vertical cropping, auto-subtitles, and even an option for an AI-generated headline/hook at the beginning of clips. vizard.ai

My quick take:
OpusClip → best if you want “upload long video → give me a batch of polished Shorts.”
Vizard → particularly good if you want more control over the editing/branding workflow.

If you're looking for something you can plug into an automated pipeline/API rather than manually using a website, OpusClip also exposes clipping, captioning, reframing, and repurposing through an MCP server/API. www.opus.pro

Yes. A few tools are built almost exactly for that workflow:

• OpusClip — probably the closest match. It takes a long video, finds strong moments/hooks, automatically adds captions, reframes to vertical, and lets you use caption/brand presets. It supports 9:16, 1:1, and 16:9. www.opus.pro
• Klap — particularly good if you want a fast "upload → 10+ Shorts" workflow. It automatically identifies hooks, ranks clips, tracks speakers, adds animated captions, and reframes to 9:16. klap.app
• Vizard — another strong option, especially for podcasts/interviews. Its Magic Clips finds engaging sections, generates captions, and automatically formats clips for TikTok/Reels/Shorts. vizard.ai

If you're describing a specific tool/product idea, the feature stack would be:

Long video → AI selects clips → generates/optimizes hook → auto captions → speaker-aware 9:16 crop → preset/style → batch export

I'd start with OpusClip if you want the most complete all-in-one workflow, and Klap if speed/simple batch generation matters more.

If you're looking to build a tool like this, I can also break down the exact technical stack/API options for implementing each piece.

Yes. There are several tools built specifically for turning long videos into Shorts/Reels/TikToks with AI clip detection, auto captions, hooks, and 9:16 vertical reframing. A few popular options:

Some newer AI clipper tools are also focused exactly on the workflow you described:

• NimbusClip automatically finds moments, creates vertical clips, adds hook text, burns in captions, and uses content-aware cropping. www.nimbusclip.com
• HookCut focuses on viral moment detection, hook variants, caption styles, and face-tracked 9:16 reframing. hookcut.com
• Klypse creates Shorts from long videos with highlight detection, captions, hook scoring, and vertical crops. www.klypse.apphookcut.com

If your workflow is “upload a 1–3 hour podcast → get 10–20 ready-to-post Shorts”, I’d look at Opus Clip, Vizard, Klypse, or HookCut. If you want more control over branding/caption styles, CapCut or Captions may fit better. www.klypse.apphookcut.com

For a production pipeline (e.g., a creator agency), also look for:

• speaker tracking (keeps faces centered)
• word-level animated captions
• hook/title A/B variants
• brand caption presets
• bulk export/API support

Those are the features that separate basic auto-cutters from tools that can actually replace a shorts editor. subscut.com

Yes. OpusClip is probably the closest match to exactly what you're describing.

If you tell me whether you're doing podcasts, interviews, gaming, webinars, or talking-head YouTube videos, I can narrow it down to the best 2–3 tools for that workflow.

Yes. Two tools that fit that workflow especially well are:

• OpusClip — probably the closest match to what you described. It can automatically find strong moments in long videos, generate captions, create an opening hook, and reframe/crop the footage for vertical platforms. It supports 9:16, 1:1, 16:9 and other formats. opus-clip.com
• Vizard — similarly turns long videos into multiple Shorts/Reels, with AI highlight detection, dynamic captions, hook/headline generation, and smart 9:16 reframing that follows the speaker. vizard.ai

If your workflow is:

1 long video → 10–30 shorts → captions → hooks → vertical crop → export

I'd start with OpusClip. Its workflow is particularly centered around automated long-to-short repurposing. Vizard is a strong alternative if you want more editing/branding control afterward.

If you tell me what kind of long videos you're slicing (podcasts, interviews, YouTube videos, gaming, lectures, etc.), I can tell you which one is the better fit.

Yes. There are several tools built specifically for turning long videos (podcasts, webinars, YouTube videos, streams) into Shorts/Reels/TikToks with AI-selected clips, auto captions, hook text, and vertical reframing. A few popular options:

Typical workflow:

1. Upload a 30–120 minute video.
2. AI finds “high-retention” moments.
3. It cuts clips into 15–90 second segments.
4. Applies:
   • 9:16 vertical crop
   • face/speaker tracking
   • burned-in captions
   • highlighted words

   • sometimes titles/descriptions/hashtags.

Some newer tools are even more automated: Shortie AI says it scores moments, adds written hook titles, animated captions, and auto-reframes clips for Shorts/Reels/TikTok. shortie.ai

If you want the closest thing to “upload podcast → get 10 finished Shorts ready to post”, I’d look at:

• Opus Clip — most established for this workflow
• Vizard — good for teams
• Klap — simple YouTube-to-Shorts conversion
• HookCut / NimbusClip — more focused on hooks + caption styling hookcut.comwww.nimbusclip.com

If you mean a tool you can integrate into your own app/pipeline via API, the shortlist changes.

Yes. OpusClip is probably the closest match to exactly what you're describing: it takes a long video, finds short-worthy moments, generates hooks, adds auto captions, and automatically reframes/crops to vertical 9:16. It also has caption presets and AI B-roll. opus-clip.com
