Others who are actually qualified have been working on this problem. This gentleman has been approaching from the other end, that of forensic examination of unmodified data; at the moment, his work involves still imagery but he appears to be moving into video.
So there is interest in proving video (un)modified. I will acknowledge that the applications are much larger when applied to 'standard' video. Still, I can't help thinking that if there is enough doubt to create this field of study, then a 'verified video stream' might be worthwhile.
