Manage CMAF VOD renditions

The JWX Platform allows you to manage the renditions in your CMAF VOD media items. You can edit metadata or delete renditions to ensure you meet compliance standards and your viewers always experience the version of your content you intend.

Edit CMAF VOD rendition metadata

You can edit the metadata associated with your CMAF VOD audio renditions and captions. Video renditions take on the metadata from the original file and are not directly editable.

Follow these steps to edit the metadata of a CMAF VOD audio rendition or caption track:

1. In your Media library, click the name of a CMAF VOD media item. The media details page appears.

2. Below the preview player, click the Assets tab. The Video, Audio, and Captions rows appear.

3. In the Audio or Captions row, click Manage. The Audio or Captions page appears.

4. In the row of a rendition or track, click ⋯ > Edit. The Edit panel appears.

5. Enter a Label or Name for the asset.

   📘

   This is the label that the viewer sees when selecting a rendition in the player.

6. (Audio renditions only) Select an Audio role from the dropdown menu.

   📘

   The role identifies the function of the track in the media, as defined by the role scheme in CTA-5005-A.
