Processing capability
Media processing feature | Description | References |
Audio and video transcoding |
| |
Video snapshots | Takes a snapshot at a specific point in a video and generates an image file. | |
Animated images | Cuts a specific segment from a video and generates an animated image file. | |
Video watermarks | Adds information such as images and text to a video stream during transcoding. The information is then merged to output a new video file with a watermark. | |
Media review | Supports comprehensive media review for videos, audio, images, and text. This includes automated review, manual review, and security review configurations.
