We used side-by-side examples to discuss manipulated video. Those comparisons were a starting point, not a reliable test: a video can look convincing and still misrepresent what someone said.
Fake endorsements can combine altered video and audio. Before acting on a promotion, check whether the person or organization actually published it and investigate the product separately. A familiar face is not evidence that an offer is legitimate.
In practice
- Check the source outside the post or advertisement.
- Do not assume every altered video has an obvious visual flaw.
