Video formats with lossless interpolation frames?

I'm playing with image-optimized diffs for storing edits to artwork. Version control seems to treat images as binary blobs, which means changes to common compressed formats like PNG/JPEG rewrite ≈90% of the file, so updates eat roughly the same space as storing separate files anyway.

Instead of writing some bit-twiddling code myself, I had an idea. We already have highly optimized algorithms for storing differences between images: video codecs.

What video codecs out there allow for lossless reconstruction through their interpolation (“b”) frames? The most common ones all understandably err on the lossy side.

For example, HEVC lossless mode – the encoder will find optimal inter or intra predictions and then losslessly code the residual.
