Automated review uses deep learning to detect prohibited content in videos, thumbnails, and titles across speech, text, and visual dimensions, covering pornography, terrorism, politically sensitive material, ads, logos, and undesirable scenes.

How automated and manual review interact

The final moderation result combines automated and manual review. The manual review result always overrides the automated result.

Only files in the Normal state can be played. Files in the Flagged or Reviewing state can be played only in the ApsaraVideo VOD console or through a security IP for moderation. Playback URLs for these files cannot be obtained through an API or SDK. However, previously distributed playback URLs remain valid.
