Last updated: 2024-12-10 11:15:55
Overview
With audio/video transcoding, you can transcode media to different formats, frame rates, bitrates, resolutions, etc. so that it can be played back on different devices.

Use Cases
Use Case | Description |
Adapt to different devices | A source media file can be transcoded to formats (such as MP4 and HLS) that are compatible with more types of devices for smooth playback. |
Increased bandwidth compatibility | A source video can be transcoded for output in multiple definitions such as LD, SD, HD, and FHD. End users can select the most appropriate bitrate depending on their network conditions. |
Faster loading | The moov atom can be moved from the end of an MP4 file to the beginning of the file, allowing the video to be played before it is entirely downloaded. |
Watermarking | A watermark can be added to a video to mark video ownership or copyright. |
Opening and ending segments | Content such as ads and promotional materials can be added to the beginning or end of a video. |
Reduce bandwidth usage | To reduce your bandwidth usage, you can use a more advanced codec (such as H.266 and AV1) or transcoding mode (Top Speed Codec transcoding) to significantly cut the bitrate without compromising the video quality. |
