Track Insertion transform

A track insertion transform is an operation that adds a track to a VOD asset and updates the asset client and server manifest with the new track.

Track side-loading is only available for MP4 content and requires a server manifest (.ism) file as input to the job. Currently, only subtitle tracks can be added to an existing VOD asset.

Track insertion transforms cannot be created from the UI; they can only be created using the transform endpoint in MK.IO API.

When selecting the track addition transform, you will need to select a source track file, and specify the targeted output asset. If you have assets in Smooth Streaming format you will first need to convert them using one of the Asset conversion Transform sample we provide.

A sample VTT track addition transform is provided in this article.
