lepton works on jpeg that are lossy, yet they manage to have a smaller file
size adding a lossless compression on top of it.
I'm not sure why it won't be possible to do the same on a h.264 file and
get a smaller file size. I know h.265 and av1 have lossless video
compression. And I recently heard about FFV1.
