Realistic AI b-roll in a Short: is the Altered content flag needed?
A realistic generated scene that did not occur needs YouTube's disclosure; a fantasy scene does not. Sort Sume clips before upload using the page's own list.

B-roll is where AI footage most often slips into a Short unmarked. YouTube's disclosure help page gives the test: does the content meaningfully alter or generate photorealistic content? It lists generating a realistic scene that did not actually occur.
Sort each clip
Run the test per clip, not per video. A Short can be mostly filmed and carry one generated shot.
| Clip | Disclose? |
|---|---|
| Generated street scene that looks filmed | Yes, realistic scene that did not occur |
| Generated product in a fantasy world | No: unrealistic, per the page's unicorn example |
| Your own footage with a color grade | No: color adjustment is exempt |
| Edited footage of a real event or place | Yes: alters footage of a real event or place |
Label placement
The page says a label shows in the video player for photorealistic content and in the expanded description for non-photorealistic or animated content.
Keep the source list
When you assemble in Timeline 1.0, each video[] slot has a source_url. Keep that array with the finished Short. It is a ready list of which shots came from where, so the Altered content answer at upload is a lookup, not a guess.
Rule of thumb
If a viewer could take any one shot for real camera footage of something that did not happen, disclose the whole upload. The cost is a description label.
