It's really ambitious, it tries to rival DaVinci Resolve with its node system, I already appreciate it a lot for its performance, though it might be lacking in some features for now.
One of them was masking, one time I even used Blender for a project (that I never completed), because its masking feature is just better and stabler, trying to animate the nodes of mask paths in Olive completely crashed it. It was some time ago now, though, so it might already be fixed.
Still, Blender is kinda underrated as a video editor, it's very capable and it's incredibly stable, I think I experienced max 1 or 2 crashes if any, while Kdenlive has always been pretty crashy for me, it also doesn't get enough love from the devs, there's so much potential in integrating the 3D viewport into the VSE, ahh if only...
Aaand now this turned into a Blender ad for some reason, lmao
Last time I tried the Linux version of Resolve, it wouldn't start up due to it being incompatible with the default AMD drivers. This was years ago, so maybe it works now.
It's definitely stable enough for doing "real work" on, though the lack of GPU accelerated timeline playback can make some more complex projects a little difficult. I've used it for proper work plenty of times over the years (I survived the Covid lockdowns entirely with paid video editing from home, on Kdenlive, as my normal work was unavailable).
I still frequently save manually with a new filename, due to old version paranoia, but if I'm honest, it's own "it saves every click in an ongoing temp file" sort of thing works great. You lose 2 seconds of work, then restart and restore.
Basic edits are likely to have no crashes at all, wheras ones where you, for example, pan and zoom with keyframes, then speed up, then reverse the footage, then try to re-edit the pan and zoom, might get its keyframes in a twist and crash frequently.
I tried a few FOSS NLEs and Kdenlive is my favorite. The native one from the Arch repos at least. I know the flatpak or AppImage versions can be problematic sometimes especially when you throw some weird files at it.
At least for me, shotcut is really unstable, they're removing features that I liked, old versions that worked previously are buggy
... at least for me, it was a bad experience overall. Hadn't had any of these problems with Kdenlive, so i switched
Do you use native distribution packages or Flatpak? Distributions packaging applications with changed dependencies from when the developer made that version can cause instability. That's one of the reasons I'm advocating that developers maintain their own Flatpak releases.
Personally I don't, it's been a while and my usage was never too professional. A quick web search doesn't seem to show anything, though that's probably due to the video editor's obscurity.
