An amateur tip that I sometimes use after I reencode something to check what i lost:

ffmpeg -i source.mkv -i suspect.mkv -filter_complex "blend=all_mode=difference" diff_output.mkv

I saw these claims before but still have not found someone to show a diff or post the source for comparison. It would be interesting.

Hehe, I occasionally use a similar approach for visual regression testing: https://untested.sonnet.io/notes/visual-snapshot-tests-cheap...
