Video formats meant for editing (e.g. mjpeg) are a series of images (intra frame only), but video formats meant for playback (e.g. H.264, HEVC, AV1) are much more compressed, by making frames depend on other frames (inter frame). Blocks of pixels in one frame copy a block of pixels from another frame (backwards and forwards!), and apply a "diff".
yeah !
There could be some interesting usages. Because this is loss tolerant I'm thinking of the consumer drones, where the stream is usually h264, when you lost a frame the entire second following get bad
