I’ve been working on my own video editing software for 8 months now. A part of that journey has been writing the most robust implementation of what is know as “smartcut”, i.e. cutting videos while recoding only small segments around the cutpoints to stitch together a whole video.

Now I’ve decided to open-source this smartcutting part of the project!

While this is not a new idea, and there are a couple open-source implementations already, I believe mine is the first one to really try to solve the problem for good, and not just treat it as a curiosity to experiment with.

I’ve also written a test suite that verifies that the implementation is working with various codecs (h264, h265, vp9, av1), container formats (.mp4, .mkv) and audio codecs (mp3, vorbis, opus, aac, flac, wav).

I also made this demo video (with the slightly provocative, but accurate) claim of “6000% faster than FFmpeg”:
