I've been thinking about how video content could be cryptographically verified. Maybe with a fractal watermark that cryptographically populated (I'm saying that in the most hand wavey manner possible)

It should be nearly invisible to the viewer, but somehow verifiable by an authentication software.

Ideally this verification method would catch edits and be able to link specific media to specific npubs.

the spec is called blossom

videos are hashed and signed, so you can prove integrity and who posted them, can then be easily mirrored without trust

a bunch of nostr apps already support it

discuss it here:
