Is there not a chain of trust here that can be enforced with fairly simple technology. And then the trust in the technology is something like a "kite mark" - a global standard of handling video content.
Let's take a simple example - I am a journalist who videos Obama talking. My raw video footage is tagged in each frame with a hash of the pixels in the frame. then I process the video, making linear cuts etc.
If i publish the whole lot as a package, anyone else can come along and rerun the processing and check the hashes match up.
This should be decentralisable and scalable. and we just have to get used to clicking the kitemark to check if anyone has verified the process or even run it ourselves.
I want to believe that something like this would work. Maybe I'm missing something, but isn't it the case that whatever signing could be performed on data coming from CCDs could also be performed on data coming from a GAN?

one could imagine a cottage industry of verifiers
