It should be federal law that any video created with GenAI should be watermarked both stenographically and visually. (Same goes for images and audio.. not sure what can be done about ascii)
You can also watermark plain text by generating "invisible" patterns.
Of course, in all these cases, the watermarks are trivial to remove: just re-encode the output with an open model. Which is why I hope there will be no federal law that tries to enforce something that is categorically unenforceable.
If the feds catch you removing watermarks you go to prison. Problem solved.
