Glad this project is still going, but have they ever fixed its stability and being able to change the framerate without breaking the whole project? Last I tried, trying to export the video with a different fps just broke all the keyframe timings...

Changing project framerate is apparently quite a hard problem, even DaVinci Resolve when you change it, warns you that you cannot change it for that project again.

Probably internally everything in a project is referenced to specific frame numbers, which would break if you changed the project framerate.
