oh yup that’s a very fair point then! you certainly wouldn’t use it for security in that case, however there are a lot of ways to implement this that don’t rely on the security of the hash function, but just uses it (for example) to point to somewhere in a trusted source to manually validate that they’re the same
we already have the trust frameworks; that’s unnecessary… we just need to automatically validate (or at least provide automatic verifyability) that a video posted on some 3rd party - probably friendly or at least cooperative - platform represents reality
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.
