  • Media review further aggregates videos, audios, images such as snapshots and thumbnails, and texts such as titles, profiles, and tags in the form of media resources. All audio and video media resources can be processed in a call, which is simpler and more efficient.

  • ApsaraVideo VOD supports workflow capabilities and allows you to manually review files based on custom configuration templates. After a media file is uploaded to ApsaraVideo VOD, the system automatically reviews the video file and calls back the review results in real time.

  • ApsaraVideo VOD review integrates all aspects of the review process. ApsaraVideo VOD review is integrated with media asset management, editing, production, distribution, and playback to meet the needs of more diverse scenarios. For example, you can transcode, discard, or archive a video after review. Non-compliant clips can also be automatically cropped and distributed.

Features

  • Intelligent review

    The intelligent review service is implemented based on a large amount of labeled data and a large number of deep learning algorithms. This feature detects illegal and prohibited non-compliant content, such as terrorism, politically sensitive content, pornography, and advertisements. The service applies to the content of videos, thumbnails, or titles from multiple dimensions such as voice, text, and vision.
