I'm just trying to cut parts of an MP4 file. What I've looked at already:
VirtualDub was great but it doesn't support MP4 files. Even with the FFMpeg Input Plugin, it can't save in Direct Stream Copy mode because
The source video stream uses a compression algorithm which is not compatible with AVI files. Direct stream copy cannot be used with this video stream.
ShotCut is open source but ridiculously large (600MB installed) and not exactly easy to use - I couldn't figure out how to cut without recompression.
MPEG Streamclip hasn't been updated since 2008 and crashes on many files.
