This demonstrates an immediate need for a trustworthy video hosting service--maybe with a companion app that records using some combination of crypto/proprietary formats/trust networks/I don't know what else, this isn't my area of expertise. Things are going to get pretty bad here soon if video evidence loses its street cred.

But how is it considered trustworthy? That's basically the central struggle every media organisation has right now and I don't see an easy answer.

Yours is an interesting idea, though. I dread to think how much it would have to exclude though - probably have no Android client because I'm sure a rooted phone could easily provide a fake video source. Maybe even on a jailbroken iOS device too. And once that becomes possible the entire platform is ruined.

Yeah, it might need to be a custom-made camera, made for news organizations and wealthy vloggers. And each device would need to be audited regularly. It would be a nightmare but not as much of a nightmare as not knowing whether anything you see on video is real or computer-generated.

Why do you need all this? Just authenticate the video file with a digital signature. It is even possible to build it into the video encoding itself, and I am almost certain there are already research papers on this, if not implementations.
