If your laptop is genuinely low-spec, I’d look at Kdenlive or Shotcut before DaVinci Resolve. For long timelines, the important thing isn’t just how long the timeline is—it’s how efficiently the editor handles decoding, thumbnails, caching, and seeking.

My picks

1. Kdenlive — my first choice.
It is unusually well suited to long-form projects on modest hardware. Kdenlive can automatically create lower-resolution copies when needed, and its proxy generation runs in the background at configurable CPU priority. docs.kdenlive.org

Kdenlive

2. Shotcut — probably the easiest lightweight option.
Shotcut has a relatively straightforward timeline and currently supports hardware video decoding for supported codecs. Its developers specifically recommend Preview Scaling and proxies on machines toward the lower end of its CPU/RAM requirements. www.shotcut.orgwww.shotcut.org

Shotcut

One important caveat: hardware decoding doesn't magically eliminate timeline lag. Shotcut notes that it has limited impact on seeking/scrubbing, so proxies can still be important for difficult footage. www.shotcut.orgwww.shotcut.org

3. LosslessCut — fantastic if your content is mostly cuts.
If you're making podcasts, gameplay, talking-head videos, compilations, etc., where you're primarily chopping footage rather than doing elaborate effects, LosslessCut can be dramatically lighter than a full NLE because it can avoid re-encoding in compatible situations.

What I'd actually use

If you're making 30–120+ minute YouTube videos:

Kdenlive → my recommendation

If you're doing mostly cuts, music, basic text and transitions:

Shotcut → probably the least frustrating

If you're doing "take 100 clips and quickly cut them down":

LosslessCut → then bring the finished pieces into Kdenlive/Shotcut

And there's a bigger factor than the editor: your footage codec. A cheap laptop can sometimes handle a 1080p H.264 file better than 4K H.265/HEVC or highly compressed phone footage. If you tell me your CPU, RAM, GPU (if any), and what resolution/codec you record in, I can recommend the best editor/settings for your exact laptop and minimize proxy use.

If your priority is long timelines on a weak laptop without constantly generating proxies, I’d look at Kdenlive and Shotcut first, rather than DaVinci Resolve.

My picks

1. Kdenlive — best overall

• Probably my first choice for a low-spec creator.
• Its timeline workflow has improved substantially, including performance improvements and better handling of long/complex projects. Kdenlive Kdenlive
• It also has timeline preview rendering, which is particularly useful when effects—not the source footage itself—are causing playback to stutter. Kdenlive
• Current version is 26.04.3 and supports Windows, Linux, and macOS. Kdenlive Kdenlive
• Best for: YouTube videos, documentaries, multicam-ish projects, lots of cuts/tracks, long timelines.
• Shotcut — best if the laptop is really weak

• Its current requirements are unusually modest: 4 GB RAM for SD, 8 GB for HD, and 16 GB for 4K. Shotcut
• Recent versions added hardware video decoding and reduced timeline waveform memory usage. Shotcut Shotcut
• Importantly, Shotcut's hardware decoding can reduce CPU usage on low-powered CPUs. Shotcut
• Best for: straightforward editing where you want the least demanding editor possible.
• LosslessCut — excellent companion

• If a lot of your workflow is simply cutting out sections, joining clips, trimming recordings, or extracting segments, don't put all of that into a full NLE. LosslessCut can avoid unnecessary re-encoding, which is extremely friendly to weak hardware.
• I'd use it alongside Kdenlive/Shotcut rather than as your main editor.

What I'd avoid

DaVinci Resolve is fantastic, but for your particular constraint I'd put it low on the list. Its color/effects engine is considerably more demanding, and a low-end integrated GPU can become the bottleneck very quickly.

Also, don't assume that "no proxies" is the same thing as "no optimization." 1080p H.264/H.265 and especially 4K H.265/10-bit footage can be brutal to decode even when the timeline itself is simple.

The setup I'd use

If I had your laptop, I'd try:

Kdenlive → 1080p timeline → hardware decoding enabled → timeline preview rendering for effect-heavy sections → proxies only for genuinely difficult source footage.

That gets you much closer to "edit a 1–2 hour timeline without babysitting proxies" than trying to brute-force everything through Resolve.

If you tell me your CPU, RAM, GPU (or laptop model) and the footage you shoot (1080p/4K, H.264/H.265, phone/camera), I can tell you which editor is likely to behave best and what settings I'd use.

For a low-spec laptop, the biggest factor is how the editor handles playback, caching, and codecs. No software can magically make 4K H.265 footage lightweight, but some editors are much better at staying responsive on weaker hardware.

Here are the strongest options:

For long timelines specifically (30 minutes to several hours), I’d lean toward:

1. Kdenlive — probably the best balance of timeline performance, features, and hardware friendliness.
2. VSDC (Windows) — very good if your laptop is older.
3. Shotcut — simple and stable.

A few settings matter more than the editor:

• Edit with 1080p timelines, even if your source is 4K.
• Record in easier codecs if possible:
  • Better: H.264
  • Harder: H.265/HEVC, 10-bit footage, some phone formats
• Put your project/cache files on an SSD if you can.
• Disable heavy effects while editing (noise reduction, stabilization, AI effects).
• Use lower preview quality (¼ or ½ resolution) before reaching for proxies.

If you tell me your laptop specs (CPU, RAM, GPU, storage type) and what you edit (gaming videos, podcasts, vlogs, shorts, 4K phone footage, etc.), I can narrow it down.

If by low-spec you mean something like 8 GB RAM, integrated graphics, and a modest 4-core CPU, I’d prioritize editors that are lightweight and handle long timelines efficiently.

My picks

1. Shotcut — best overall for a weak laptop

Shotcut official site

This would be my first try. Shotcut is relatively lightweight, supports native timeline editing, and its recent versions have specifically improved timeline performance and memory usage. Version 26.1 also added hardware video decoding. www.shotcut.orgwww.shotcut.org

The important part: you don't necessarily need proxies for everything. You can combine hardware decoding with lower preview resolution, and only proxy the footage that actually causes trouble. Shotcut explicitly recommends Preview Scaling + Proxy when you're near the bottom of its hardware requirements. www.shotcut.org

2. Kdenlive — best if you want more serious editing tools

Kdenlive official site

Kdenlive is another excellent low-spec option. It's more feature-rich than Shotcut while remaining considerably less demanding than something like Resolve. It has extensive timeline/project-management features and configurable proxy behavior. docs.kdenlive.org

I'd pick Kdenlive if you're making long-form YouTube videos with lots of cuts, audio tracks, B-roll, subtitles, and graphics.

3. DaVinci Resolve — powerful, but not my recommendation for genuinely low-spec hardware

Resolve is fantastic, but if your complaint is "I don't want to constantly proxy footage," it's usually going in the wrong direction. It benefits much more from a capable GPU, plenty of RAM, and fast storage.

For your specific use case

I'd rank them:

One particularly encouraging sign for Shotcut: its developers recently fixed a crash involving very long playlists and have made several timeline/waveform performance improvements. www.shotcut.org

If you tell me your laptop's CPU, RAM, GPU, and whether your footage is 1080p or 4K (and H.264/H.265), I can tell you which editor I'd use and the exact settings I'd start with.

If your laptop is genuinely low-spec and you want to edit long timelines without living in proxy hell, I’d look at these first:

🥇 I'd start with Shotcut

Shotcut is unusually sensible for a weak laptop. It has native timeline editing, doesn't require importing/transcoding everything, and recent versions added hardware decoding and further timeline/performance improvements. www.shotcut.org

More importantly, you can combine Preview Scaling + proxies so you're not asking your laptop to constantly decode full-resolution footage. Shotcut specifically recommends those features when you're near the bottom of its hardware requirements. www.shotcut.org

For a low-spec machine, I'd use:

• 360p/540p preview
• 720p proxies for 4K footage
• hardware decoding if your laptop supports it
• minimal real-time effects while assembling
• export from the original media

🥈 Kdenlive if your projects get complicated

Kdenlive is probably my choice if you're doing 30–120+ minute videos with lots of tracks, B-roll, audio, captions, etc. Its proxy and timeline-rendering workflow is designed specifically to keep complex timelines playable when the hardware can't handle everything in real time. kdenlive.org

It's also free/open-source.

One important caveat

No editor can magically make a weak CPU decode 4K H.265/HEVC smoothly. If your footage is from a phone, GoPro, screen recorder, etc., the codec may be the real problem rather than the length of the timeline. Even Shotcut's current hardware decoding has limitations, and its documentation still recommends proxies for smooth seeking/scrubbing in difficult footage. www.shotcut.org

If you tell me your laptop's CPU, RAM, GPU (if any), and what resolution/codec you shoot in (e.g. 1080p H.264 or 4K H.265), I can tell you which editor I'd pick and the exact settings I'd use to make it as lag-free as possible.

If the laptop is genuinely low-spec, I’d look at Kdenlive or Shotcut before DaVinci Resolve. The key is that long timelines themselves aren't necessarily the problem—codec decoding, effects, and high-resolution footage are.

My picks

1. Kdenlive — best overall for long projects

• Relatively light compared with Resolve.
• Supports long, multi-track timelines well.
• Has proxy clips, preview-resolution playback, and timeline preview rendering. Timeline preview rendering can render difficult sections in the background so you can play them smoothly. docs.kdenlive.org
• Official requirements are surprisingly modest: 4 GB RAM for SD, 8 GB for HD, 16 GB for 4K. docs.kdenlive.orgwww.shotcut.org
• Download Kdenlive

2. Shotcut — best if simplicity/performance matters

• Free, open-source, and doesn't require importing/converting everything into a proprietary project format.
• Its current versions support hardware decoding, which can reduce CPU load on weaker machines. www.shotcut.org
• Has Preview Scaling + Proxy Editing, specifically designed to reduce realtime processing. www.shotcut.org
• Official minimums are 4 GB RAM for SD, 8 GB for HD, and 16 GB for 4K. www.shotcut.org
• Download Shotcut

What I'd actually use

One important caveat: no editor can completely eliminate proxies if you're throwing 4K/60 H.265 footage at a weak CPU. Even Shotcut's developers note that hardware decoding doesn't necessarily fix seeking/scrubbing, where proxies remain important. www.shotcut.org

If you tell me your CPU, RAM, GPU (if any), and whether your footage is 1080p/4K + H.264/H.265, I can recommend the specific editor and settings most likely to let you edit long timelines with minimal proxying.

If your priority is long timelines on a low-spec laptop with minimal proxy use, I’d look at editors designed around efficient playback rather than simply throwing more GPU/CPU at the problem.

Best fits

• ightweight video editing software for low-spec laptops
• rofessional video editors optimized for long timelines and efficient playback

In practice, Kdenlive and Shotcut are good places to start if your machine is modest. For more demanding professional workflows, DaVinci Resolve can be excellent, but it generally benefits from substantially stronger hardware and may require proxies/optimized media sooner.

What matters more than the editor

For long timelines, look for:

• Low-resolution timeline previews / proxy-free preview modes
• Hardware decoding for H.264/H.265
• Background rendering
• Optimized media / render-cache controls
• Ability to disable heavy effects while editing
• Good performance with many cuts without loading every clip at full resolution

If you tell me your CPU, RAM, GPU (if any), and the resolution/codec you usually record in (e.g. 1080p H.264 or 4K HEVC), I can narrow this down to the best 2–3 choices for your laptop.

If your priority is long timelines on a weak laptop with as little proxying as possible, I’d start with Kdenlive or Shotcut, not DaVinci Resolve.

My ranking

🥇 Kdenlive would be my pick. Its current requirements are fairly modest—8 GB RAM for HD and 16 GB for 4K—and it specifically provides preview-resolution reduction and timeline preview rendering for weaker machines. docs.kdenlive.orgdocs.kdenlive.org

The big advantage for your use case is timeline preview rendering. Instead of constantly converting your source footage into proxies, Kdenlive can render the difficult sections of the timeline in the background and then play those sections smoothly. docs.kdenlive.orgdocs.kdenlive.org

Kdenlive official site/documentation

🥈 Shotcut is probably the easiest alternative. It has hardware decoding in current versions and Preview Scaling, which can substantially reduce CPU load on a low-powered machine. That said, Shotcut itself notes that hardware decoding doesn't completely solve seeking/scrubbing problems, so proxies can still be useful with difficult footage. www.shotcut.org

Shotcut official site

One important catch

The footage matters more than the length of the timeline. A 3-hour timeline of 1080p H.264 can be easier than a 20-minute timeline full of 4K HEVC, 10-bit footage, effects, and multiple layers.

If you tell me your laptop CPU, RAM, GPU (if any), and whether your footage is 1080p/4K + H.264/HEVC, I can tell you which editor is likely to perform best without proxies and what settings I'd use.

If your priority is long timelines on a low-spec laptop with as little proxy dependence as possible, I’d look at Kdenlive first, then Shotcut.

My ranking

Kdenlive would be my first experiment. It has relatively modest requirements—8 GB RAM is listed for HD, 16 GB for 4K—and its timeline preview rendering can render difficult sections in the background so they play smoothly afterward. docs.kdenlive.orgdocs.kdenlive.org

The important caveat: no editor can magically make a low-end CPU decode 4K H.265 footage, multiple layers, effects, and a huge timeline in real time. Kdenlive's own documentation says timeline playback is CPU-heavy. docs.kdenlive.org

Shotcut is also worth trying, particularly if you want something straightforward. Its current versions have hardware video decoding, which can reduce CPU usage on supported hardware. However, Shotcut explicitly says hardware decoding has limited impact on seeking/scrubbing and still recommends proxies for smooth editing. www.shotcut.org

One thing I'd change in your workflow

If you're editing hours-long footage, don't think only in terms of "which editor avoids proxies." The bigger win is using edit-friendly source media.

For example:

Camera H.265/HEVC → edit-friendly H.264/intraframe media → long timeline

is often much easier for a weak CPU than:

Camera H.265/HEVC → enormous timeline → hope hardware decoding saves you.

And if your footage is already H.264/H.265, avoid putting hundreds or thousands of tiny clips on one enormous timeline when you can organize them into smaller sequences/projects first.

For Kdenlive specifically, its proxy system defaults to 640px-wide proxies, and it lets you benchmark different proxy profiles against your machine. docs.kdenlive.org

If you tell me your laptop specs

Give me your CPU, RAM, GPU (if any), and whether your footage is 1080p/4K + H.264/H.265, and I can tell you which editor I'd actually use on that machine—and what settings I'd use to keep 2–10+ hour timelines responsive.

For a low-spec laptop, the biggest factor is how efficiently the editor handles memory, decoding, and caching. No editor can make a weak CPU/GPU magically fast, but some are much better at keeping long timelines usable without forcing you into proxy workflows.

Here are the strongest options:

A few settings matter more than the editor:

• Edit at 720p/1080p preview resolution even if your final export is 4K.
• Use H.264/H.265 “optimized media” or proxies only for the heaviest clips (4K, phone footage, screen recordings).
• Put cache files on an SSD if possible.
• Avoid stacking lots of effects, noise reduction, motion blur, and AI tools while editing.
• Keep timelines organized: break a 3-hour project into sequences/scenes instead of one giant timeline.

For a low-spec laptop, I’d usually rank them:

1. Kdenlive — best balance of timeline length and performance
2. VSDC (Windows) — best if your machine is old
3. DaVinci Resolve — best features, but needs careful settings
4. Shotcut — simplest lightweight option

If you tell me your laptop specs (CPU, RAM, GPU, storage type) and what you edit (gaming videos, podcasts, Shorts, 4K camera footage, etc.), I can narrow it down.

If your priority is long timelines on a weak laptop without living in proxy-land, I’d look at these first:

1. Shotcut — probably my first pick

Shotcut is unusually friendly to modest hardware. Its current versions support hardware video decoding, preview scaling, hardware encoding, and multi-core processing. Its developers specifically note that hardware decoding can reduce CPU usage on low-powered CPUs. www.shotcut.org

The big caveat: hardware decoding doesn't completely solve scrubbing/seek performance; Shotcut still recommends proxies for difficult footage. www.shotcut.org

Best for: long YouTube timelines, talking-head content, screen recordings, straightforward cuts, lots of clips.

2. Kdenlive — best if you need a more serious editor

Kdenlive is my other strong recommendation. It has timeline preview rendering, which is particularly useful for long timelines with effects: it can render troublesome sections in the background so playback becomes smooth without requiring proxy media. docs.kdenlive.org

Its official requirements are also quite modest: 8 GB RAM for HD and 16 GB for 4K, with a 4-core CPU recommended for HD. docs.kdenlive.org

Best for: longer/complicated projects, multiple tracks, effects, captions, audio work, and people who want a Premiere-like workflow without Premiere's hardware demands.

3. DaVinci Resolve — great, but not my low-spec recommendation

Resolve is excellent, but if your laptop is genuinely low-spec, I'd skip it unless you have a reasonably capable discrete GPU. It tends to be much more demanding, particularly once you add color grading, Fusion, noise reduction, etc.

What I'd choose

One important point: timeline length itself isn't usually the thing that makes an editor slow. Codec, resolution, frame rate, effects, number of tracks, and how efficiently the editor handles media matter much more.

For example, a 2-hour 1080p H.264 talking-head project can be easier on a laptop than a 20-minute 4K HEVC project with effects everywhere.

If you tell me your laptop's CPU, RAM, GPU, and whether your footage is 1080p/4K + H.264/H.265, I can tell you which editor I'd pick and the settings I'd use to minimize proxying.

If your priority is long timelines on a weak laptop, I’d look at Kdenlive first, then Shotcut.

My ranking

Kdenlive is probably your sweet spot. Its current requirements are relatively modest: 4 GB RAM for SD, 8 GB for HD, and 16 GB for 4K. More importantly for your use case, it has timeline preview rendering, which can render effect-heavy sections in the background so they play smoothly without having to proxy the entire project. docs.kdenlive.orgdocs.kdenlive.org

Kdenlive

Shotcut is a close second. Its current version supports hardware video decoding, which can reduce CPU usage on low-powered machines. However, the developers specifically note that hardware decoding doesn't completely solve seeking/scrubbing problems, so proxies can still be useful. www.shotcut.org

Shotcut

The important distinction

If by "long timelines" you mean something like 1–3 hours with hundreds of cuts, don't focus solely on how long the timeline is. The bigger killers are:

• H.265/HEVC footage
• 4K footage
• 10-bit footage
• lots of effects
• noise reduction
• stabilization
• multiple video layers
• huge numbers of thumbnails/waveforms

For a low-spec laptop, Kdenlive's combination of proxies + timeline preview rendering + adjustable preview resolution is particularly useful. You can leave most footage native and render only the difficult sections. docs.kdenlive.org

What I'd actually use

If you're making YouTube videos, podcasts, talking-head content, commentary, gaming videos, documentaries, etc., I'd start with:

Kdenlive → 1080p timeline → low preview resolution → timeline preview rendering for effects-heavy sections.

If Kdenlive's interface doesn't click with you, try Shotcut. Both are free/open-source and considerably more appropriate for an underpowered laptop than Resolve.

If you tell me your CPU, RAM, GPU (if any), and whether your footage is 1080p/4K + H.264/H.265, I can tell you which editor I'd pick specifically for your machine.

If your priority is long timelines on a weak laptop with as little proxy work as possible, I’d look at these first:

1. Kdenlive — my first pick

Kdenlive

Kdenlive is probably the best balance for your situation. It supports relatively modest hardware—its current requirements list 4 GB RAM for SD and 8 GB for HD—and has timeline preview rendering, which can render difficult sections in the background rather than requiring you to proxy all your footage. docs.kdenlive.org

Why I'd try it:

• Handles long/multitrack projects reasonably well.
• Background timeline rendering is excellent for effects-heavy sections.
• Free and open source.
• You can use proxies selectively rather than making your whole project proxy-based.
• Particularly attractive if you're editing mostly 1080p H.264/H.265 talking-head, gaming, YouTube, etc.

The catch: Kdenlive's timeline playback is still fairly CPU-dependent, so a really weak CPU won't magically become fast. docs.kdenlive.org

2. Shotcut — excellent lightweight alternative

Shotcut

I'd put Shotcut very close behind Kdenlive. Its newer versions have added hardware video decoding, which can reduce CPU load on low-powered machines. www.shotcut.org

It's also quite good for straightforward editing without a massive effects stack.

One caveat: Shotcut's own documentation says hardware decoding doesn't necessarily make scrubbing/seeking dramatically faster, and proxies can still be necessary for smooth editing. www.shotcut.org

3. DaVinci Resolve — powerful, but probably not what you want

DaVinci Resolve

Resolve is fantastic, but on a genuinely low-spec laptop I'd avoid it unless you have a decent GPU and enough RAM. Its strength is using the GPU heavily, whereas your goal is specifically to avoid fighting your hardware.

What I'd choose based on your laptop

One important thing: the codec matters almost as much as the editor. A cheap laptop can often handle a long timeline of easy-to-decode footage much better than a short timeline full of 4K H.265/10-bit phone footage.

If you tell me your CPU, RAM, GPU, and whether you're editing 1080p or 4K, I can give you a much more specific recommendation—and tell you which editor is most likely to let you edit without proxies.

If your priority is long timelines on a weak laptop without living in proxy files, I’d look at these first:

1. Kdenlive — my first choice

Kdenlive is probably the best balance of full-featured editing + relatively modest hardware demands.

• Handles long, multi-track projects well.
• Has configurable proxy clips, but you can often edit 1080p footage directly if your machine can decode it.
• Current 26.04 releases have continued focusing on stability and performance. kdenlive.org
• Good choice if you're doing YouTube/content-creator work rather than just basic cuts.

2. Shotcut — best for genuinely low-spec machines

I'd seriously consider Shotcut if your laptop is really underpowered.

Its current version has hardware video decoding, multi-core processing, preview scaling, and proxy editing. www.shotcut.org

The important caveat: Shotcut itself says hardware decoding doesn't magically fix seeking/scrubbing, and proxies can still be necessary for difficult footage. www.shotcut.org

Its published minimums are roughly 4 GB RAM for SD, 8 GB for HD, and 16 GB for 4K, so it's one of the more realistic choices for older laptops. kdenlive.orgwww.shotcut.org

3. DaVinci Resolve — powerful, but not my pick here

Resolve is excellent, but if your laptop is low-spec, I'd generally avoid it. Its color, Fusion, effects, and GPU requirements make it much more demanding than Kdenlive/Shotcut.

What I'd actually use

One big tip: the codec matters almost as much as the editor. H.265/HEVC, 10-bit footage, phone footage with variable frame rate, and 4K60 can make even a relatively simple timeline miserable on a weak CPU. If your source is mostly 1080p H.264, Kdenlive or Shotcut can be surprisingly comfortable.

If you tell me your CPU, RAM, GPU, and whether you're editing 1080p/4K, I can tell you which editor is likely to give you the smoothest timeline—and the settings I'd use to minimize proxying.
