What liveness verification means, and why it's on record

The difference between a face someone uploaded and a face someone proved was theirs is one check, and it happens before publication rather than after a complaint.

How to extend a clip without breaking continuity

Extension continues a shot rather than generating a new one. Where the join succeeds, and what makes it visible.

Making your own generated actor instead of picking one

Two routes, and the difference between them isn't quality. One asks nothing of you; the other asks you to attest to three things before it will proceed.

Why your AI scenes don't match shot to shot: the coverage problem

Your shots look good individually and wrong together. That's a coverage problem, and film has solved it for a century.

Do you have to label your AI video? Disclosure rules for US creators

Three platforms, one EU regulation and the FTC all want something different, and your generation tool probably provides none of it.
