I'm confused by the README. It makes references to YouTube video, but also "lossless video".
Is this about recompressing existing H.264[1] videos (like downloaded from YouTube) losslessly, or is it about making new videos from a source losslessly? The former reminds me of JPEG XL's ability to re-compress the DCT on old JPEGs, but even as you get better compression, you still don't have a lossless image.
[1] To be fair, H.264 can be lossless in the first place, but YouTube does not serve up such files.
