I have done some basic video editing using Blender on OS4. It isn't really intuitive, but you get used to it once you learn how to use it, there are some tutorials on the net. The major drawbacks I have found are:
- the video codec used in the videos produced by my camcorder aren't recognised by Blender (MP4 container, H.264 codec - Blender's FFMpeg version seems to be the culprit here), I need to convert them with mencoder before they can be loaded
- I have not found an easy way to do a combined audio/video crossfade between two videos. There's an option to do a video crossfade, for the audio part I had to manually fade it out and in
- for high resolution videos (i.e. 1080p) there's a very handy feature which generates a thumbnail out each frame of a video, making it possible to edit them on low specced machines. What's really missing is a macro to automatically generate them for all the video/audio streams loaded in a project
It might be possible to fix the latter two points using Python scripts, I have not tried to write one though.
