YouTube AI label: below the player, and an overlay on Shorts

YouTube's blog of May 27, 2026 says the disclosure label for photorealistic and meaningfully AI altered or generated content now sits directly below the video player, above the description, on long-form videos, and as an overlay on the video itself on Shorts. It is now the single label format for that content.

Where does each label show?

Does a caption line in the video replace the label?

The blog does not say so. The label comes from the creator's disclosure or YouTube's own detection signals, and the blog does not mention on-screen text as part of either. A line you burn into the clip is your own text, and it sits in addition to whatever YouTube shows. For the disclosure rules themselves, read what needs disclosure and burned captions.

How do I burn in my own line with Sume?

Video captions takes a required video_url and, for authored overlay copy, cues or segments, which skips speech-to-text. Each cue carries text plus start and end. Silent clips fail as caption_no_speech when you rely on speech-to-captions, so use cues for them. See Video captions.

Can I put a still and a video on screen together?

Timeline compose takes one still and one video and returns one MP4 with both on screen at once. That is useful for a title card or a note beside the clip. It is a layout tool; it does not set YouTube's label. See Timeline compose.
