I use Kdenlive about once or twice a year to edit/compile racecar footage. The UI has been friendly enough to relearn each time because I use it so infrequently. I've never had any complaints about it, though I'm not doing anything crazy. But it's extremely intuitive and even as a new user it doesn't seem to get in my way, which is just about the highest praise I can give to a piece of interactive software.

Unfortunately I can't compare against Lightworks or Blender, because I tried Kdenlive and it worked great, and there was no reason to search for alternatives.

OT, but: what type of racecars? =D

Lemons! We race a fiat x1/9

Blender video editor is extremely feature rich in terms of the keyframing effects you can do with it, the only problem being: it's slow, and it doesn't always sync audio with video even when you ask it to.

With Kdenlive, it's frustrating to add a simple block of text (you can have to create an overlay, and then configure that overlay, and place it roughly where you want), but the final rendering takes only minutes and it's stable enough to work with for larger projects.

Can't comment on Lightworks.

> Blender video editor is ... slow

Might be time to think about trying Blender again. This was posted here on HN about a month ago. https://aras-p.info/blog/2024/02/06/I-accidentally-Blender-V...

I tried blender video editor just the other day, and this problem was still there -to the point that I actually went out and found kdenlive the same day!

I don't have experience with any of those, but I have used ShotCut [1], which is free an open-source. It works well enough on those rare occasions I've needed it (e.g. editing a video of my child playing an instrument for their class). If you're looking for "FOSS" and "easy to use" ShotCut might be worth looking at.

In my experience, Kdenlive and Shotcut are more or less on par with iMovie. Da Vinci Resolve works on all three major OSes and is actively usurping the prosumer market previously held by Premiere and Final Cut Pro. (It even has an advanced, node-based compositing tool for visual effects and motion graphics.) It's not open source, though it's free unless you need some features aimed more at serious commercial stuff.

or simply H264/H265 which is a dealbreaker for a lot of people.

The free version has h264 and h265, as far as I can tell. I rendered a mp4, h264 video in resolve today. My first time using the software and it was surprisingly capable. (I needed to blur a moving face in a video)

Not in Linux, only in Mac and Windows

On Mac and Windows, the free version of Resolve supports H.264 and H.265 (using OS-supplied codecs IIRC).

Linux H.264 and H.265 support is Studio-only[1] (presumably because royalties).

If you don't care about any other Studio features, converting to/from an intermediate codec — DNxH[DR], say — on import/export using another tool like FFmpeg seems like a reasonable workaround for most applications.

Since Resolve doesn't support H.264/H.265 passthrough (on any platform), the only generation loss added by this approach will be from DNxH[DR] encoding, which, assuming a sufficiently high bitrate for the intermediate codec, should be minimal.

Note that even Resolve Studio doesn't support AAC audio on Linux[2], so, for many H.264/H.265 projects, you'd end up with pre-/post-conversion steps even if the video codecs were supported.

Unfortunately iMovie is still in a different league to Kdenlive or Shotcut. Think iPhone vs iPAQ.

Do Kdenlive or Shotcut even support GPU rendering yet?

Blender is probably still the best open source video editor by quite some margin.

if you need a feature set like iMovie, why not use davinci resolve? its available on linux. not open source but neither is imovie

Good question - I didn't actually know it was free until now. I'll try it next time.

My experience has been: Kdenlive is full-featured and weird to use. Blender is missing features and weird to use. Openshot is simple and easy, but crashes. shortcut is simple and easy and does not crash.

Ugh, Shotcut, not Shortcut

As someone who rarely edits video and doesn't need or want to become an expert, but had one to do last year, I ended up using Kdenlive. I know I also tried Shotcut and Openshot (because they're on my machine) but not why I rejected them, and I don't remember whether I tried DaVinci.

Both kdenlive and blender are not that great at working with text which makes them hard to recommend for serious use.

kdenlive is the easiest. It has annoying bugs but they're relatively easy to work around.

Of course, like any open source project, part of the reason why those bugs exist is my fault for not engaging with the project ... but let's ignore that

I've used Kdenlive, Shotcut, Blender and Olive [1]. They all have strenghts and weaknesses, so I choose which one to use depending on what I'm trying to do, or sometimes I use two of them through a single video project.

One thing to note is that Kdenlive and Shotcut both use the MLT video editing framework [2] under the hood, so their capabilities and constraints are very close to each other's. That said, their UIs are their own and some things may be easier to do in one over the other, may be a matter of personal preference. AFAIK Shotcut is developed by the same people who built MLT, but I don't think that gives it any particular advantage. Also both of these apps have the largest ready-made effects toolbox out of the four apps I mentioned at the top.

Blender's VSE (video sequence editor) is great if you need fine-tuned 2D animations of elements because you can use all the same awesome keyframing tools you'd use for 3D animation, but it's severely lacking in other aspects, especially in the effects dept (you can crop, blur, mask, but not much else). For some reason you can't use Blender's compositor node system with video, which would enable many more capabilities if possible. There's also a steeper learning curve if you've never used Blender before because its UI breaks many conventions.

Olive is a newcomer that doesn't get enough attention, but IMHO it was at one point the most promising OSS video editor out there. Sadly the developer works on it on his free time, and he's recently said that he's pausing development because he doesn't have the resources to work on it any more. I'm really hoping a miracle happens.

There's two versions of Olive, 0.1 and 0.2 which is a complete rewrite. Both versions are good, but they work pretty differently. What got me excited about 0.2 is that its effects are node-based (unlike MLT-based editors which are stack-based), which enables far more advanced editing, although you probably wouldn't need that unless you're working on something quite ambitious.

> Without getting into the philosophy of open source vs proprietary and the like, but just as someone who very occasionally needs to edit video on Linux, how does Kdenlive compare to something like Lightworks or the Blender video editor?

Blender features a node-based compositor (Like Nuke) and an NLE (movie editor). Both these tools are fine when used within a Blender workflow, but they are troublesome to use in a stand alone capacity.

In my opinion, the most important feature of an NLE is its media optimization strategy without which editing is a chore. I now use DaVinci by Blackmagic, which is free. They inherited the amazingly efficient proxy system from the DaVinci colour grader. To this Blackmagic added their own codec voodoo which is not insubstantial. DaVinci and Blackmagic footage together run as smooth as butter.

Lightworks hands down has the absolute best workflow for cutting and assembling video. Nothing else comes close. But like you said, they want you to pay for for anything above 720p. The downside is that it is really slow on my Core i9 Mac with 32 GB memory. The forums lead me to believe this is just an issue with the Mac platform, so Windows and Linux user probably don't experience this. I'm not saying it is slow at playback or seeking—it is really just the UI that's slow like there's a noticeable latency from a click to when a menu appears and don't even try dragging stuff around.

Avid Media Composer is also free but limited to 1080p and has many other limitations that can make it tricky for all but the simplest projects. Again, if you pay up you get what Hollywood editors use, but at $20 to $50 per month subscriptions isn't great for occasional use. It requires some setup and configuration that's not intuitive. I had to google how to have it use only one display and not to just assume I want it to take over all attached displays. It also has a bunch of DRM and copy protection crap that requires a bunch of additional programs and runs permanent Java processes.

Blender has a video editor. That much is true. It just isn't very good. Editing is imprecise and clumsy. You have to manually add frame allotments to the timeline if you go past the runtime. It's only saving grace is the ability to do 4K (probably higher if you want). There's no previewing a clip before you place it on the timeline. All editing is done on the timeline by positioning the playhead. There is an upfront cost for proxy editing, so if your source material is high resolution and long, expect to wait a long time for it to process the clips before you can play or edit them. I've found that when performance starts to suck you'll have to manually rebuild the proxies—maybe go to lunch.

I haven't tried Kdenlive, but its editing ability looks similar to Blender in that you have to put the clip on the timeline before doing anything. Coming from Lightworks or Media Composer this workflow sucks. I'm still going to give it a try, but I'm not sure it is for me.
