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.
