Good to know about YouTube videos
- YouTube asks creators to disclose realistic altered or synthetic content; when they do, an “Altered or synthetic content” label appears in the description. Many AI videos are uploaded without one.
- Free scans take videos up to 3 minutes; a one-time Deep Scan takes up to 10. For a longer video, download it, trim the part you care about and upload that.
- Deep Scan checks a frame every second and the whole soundtrack, which matters for long explainers where only part of the voice may be cloned.

Questions
- Does a missing AI label mean the video is real?
- No. Labels depend on creators being honest, and fakes are often re-uploaded without one. That's why our checks look at the video itself.
- Can it check a live stream?
- Only after it ends and is saved as a video. Then paste its link, or upload a trimmed clip.
