You know, contracts are just pieces of paper. They can easily be faked. Yet try going on court and say that a contract with your signature is invalid because it could be fake. Your argument will be rejected, because it doesn't matter if it could be faked, it matters if you are alleging that it was faked. So the same thing should be the standard for video. Someone shows a video of you doing something. Either say under penalty of perjury, that you did not do that, and then the authenticity of the video can be looked into, or the video will be accepted as authentic. You don't get a preemptive "this could be fake, so lets ignore it".
