Live Clipping

Live clipping allows you to create CDN servable media files from your HLS stream while it is in progress. This requires a Real-time streaming account and API key in addition to your THEOlive channel. For more details on the capabilities of the Media Asset API, refer to our Media Asset API guide and contact your Dolby Account Team to help you get set up.

To create a clip for a live stream, call the Create Media Asset endpoint, specifying your channelId, startTime and "hls" as the targetFormat. See below for an example request.

curl --request POST \
  --url https://api.millicast.com/api/v3/media/assets \
  --header 'Authorization: Bearer abc123' \
  --data '
{
  "channelId": "<channelId>",
  "startTime": "2026-01-15T01:33:33Z",
  "stopTime": "2026-01-15T01:34:33Z",
  "targetFormat": "hls"
}
'

Use the mediaAssetId in the response to check the completion status of the clip and retrieve a download URL via the Read Media Asset endpoint.
