Why does this mean AI-aided color correction, 25fps to 30fps, or upscaling 480p to 1080p should be treated the same? Using AI to make someone say something different (even if only for a small part of the video) is very clearly different, that's deception. Why does AI editing 3 seconds of audio from a president's speech be treated different from when a human does it without AI?
It sounds like your argument is about deceptive editing. Why not just require labelling deceptive editing? That way there can be place for comedy channels to do so for comedic purpose (rather than blanket ban on deceptive edits).
Almost any photograph taken with a mobile phone is AI edited because phones come with AI to enhance photo quality (e.g. Deep Fusion, Smart HDR), should any photo taken with a mobile camera be labelled AI now?
