    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
