ApsaraVideo VOD:Manual review

Last Updated:Dec 01, 2023

ApsaraVideo VOD supports the manual review feature. We recommend that you use the automated review feature to review videos on media platforms. Then, perform manual reviews only on files that contain suspected violations. This topic describes how to use the manual review feature and how to view the review history.

Overview

If you use the manual review feature, your files are reviewed by professional reviewers. This allows you to detect and block illegal and non-compliant videos in advance or take them offline. This reduces the adverse impact caused by illegal and non-compliant content.

Usage notes

  • The final review result of an audio or video file is determined by the results of automated review and manual review. If the results of automated review and manual review are different, the manual review result takes precedence over the automated review result.

  • Only audio and video files in the Normal state can be played on other platforms. You can play audio and video files in the Blocked or Reviewing state only by using the ApsaraVideo VOD console or IP addresses in review security groups described in Security IP address preview. However, unauthorized users can play the audio or video file if the playback URL is leaked. You cannot call API operations or use SDKs to obtain the playback URLs of audio or video files that are in the Blocked or Reviewing state.
