Other customers have master assets that contain black segments where advertisements would be inserted during broadcast. The RadiantGrid black-detection parser can be used during ingestion to locate these segments of black video, and the list of non-black video ranges will be used to create virtual clips that reference the master asset. This list of virtual clips will be stored as metadata with the master asset. These virtual clips can be assembled into the transcoded output file, which would no longer contain these black interstitial segments.
In addition, during program assembly, 32-bit (alpha-channel) static images or motion video can be overlaid on the source media during transcoding. These overlays can occur at specific times during the video, or repeatedly on a regular period. The overlay functionality is often used for overlaying logos, ratings graphics, or titles.
