I keep expecting to see more research into side channel attacks for encrypted video. A fair amount of work has been done for similar attacks on audio streams with VBR codecs. Secure encrypted voice requires using a codec in CBR mode, but that's not really possible for video. It's perhaps likely that video is too complex to leak anything usable through that type of side channel, but I haven't seen much discussion either way.
