Great points and I agree. I also think the signature needs to be built into the stream in a continuous fashion so that snippets can still be authenticated.

Agreed. Embed a per-frame signature it into every key frame when encoding. Also include the video file time-stamp. This will mean any clip longer than around 1 second will include at least 1 signed frame.

Merkle tree hashes exists for this purpose

Note that videos uses "keyframes" so you can't extract arbitrary frames in isolation, you need to pull multiple if the frame you're snapshotting isn't a keyframe itself
