In a groundbreaking move, YouTube is ramping up its transparency efforts by introducing prominent disclosure labels for videos featuring significant photorealistic AI use. The new system, set to roll out in May 2026, will automatically detect and label such content, providing viewers with crucial context at a glance. This change aims to combat the rise of misleading AI-generated content, such as fake movie trailers that have deceived millions in the past, including unofficial Avengers: Doomsday clips. The platform is also addressing issues in children's content and animated videos by placing disclosures in expanded descriptions. Creators can challenge incorrect labels in YouTube Studio, while permanent disclosures will be applied in select cases. This shift towards transparency is part of an ongoing effort to balance creator control with viewer information in the evolving AI landscape. Notably, YouTube has already taken down two major channels responsible for generating billions of views with fake movie trailers, following a copyright dispute with Disney.
