I think the best bet is really video formats with multiple embedded streams carrying complementary frame data (already exists) so you decide video quality based on how many streams you want to merge in playback.

If you then hashed the streams independently and signed the list of hashes, then you have a video file which can be "compressed" without breaking the signature by stripping out some streams.
