ApsaraVideo VOD provides a manual review service. For platforms that host short-form videos, media content, and other video files, we recommend using automated review for initial screening and then escalating suspected violations for manual review.
Overview
Manual review enables your reviewers to assess audio and video content and submit review results. You can proactively take non-compliant media offline to prevent or minimize negative impact after publication.
Usage notes
The final moderation result of an audio or video file is determined by both the automated and manual moderation results. However, the manual moderation result always overrides the automated moderation result.
After media moderation, only audio and video files in the Normal state can be played. Audio and video files in the Flagged or Reviewing state can be played only in the ApsaraVideo VOD console or using a security IP for moderation. You cannot obtain playback addresses for these files using an API or SDK. However, any valid playback addresses that have already been exposed can still be used for playback.
Billing: The basic manual review feature in the ApsaraVideo VOD console is free of charge. Manual review is performed by your own reviewers in the ApsaraVideo VOD console, and ApsaraVideo VOD does not charge fees for this operation. Automated review is a paid service and is billed based on the total duration of the reviewed videos.
