About track mapping
This feature is part of the licensable AppCenter Pro option.
AppCenter lets you configure audio input and output routing, assign labels to audio tracks, or specify
which video track you want to be the key. You can have multiple tracks with the same name in a
clip. Track mapping is supported for individual clips. It is not supported for clips in a playlist.
Labeling the audio tracks in a clip and the output channels in Configuration Manager allows you to
map specific tracks to specific output channels. You can assign output labels to primary output
channels alone or to both primary and secondary output channels. (If there is no label on the primary
output channel, you cannot assign a label to the secondary output.)
AppCenter maps the audio tracks to the output channels based on specific criteria. The following
sections give a detailed description of the track mapping that results based on each of these criteria:
• If no labels are assigned to any output channel
• If unique labels are assigned to audio tracks and output channels
• If unique labels are assigned to audio tracks and output channels
• If language groups are used
• If the primary output alone is labeled
• If both primary and secondary outputs are labeled
• If no output labels match the track labels
• If no labels are assigned to any output channel
If no labels are assigned to any output channel
If no audio output routing is specified, AppCenter plays out the audio tracks according to their order
in the clip, regardless of the labels of the individual tracks. In the following illustration, the first
four audio tracks are routed to audio output channels 1 through 4.
If unique labels are assigned to audio tracks and output channels
If you assign unique labels to each of the tracks in a clip, and assign the same labels to a corresponding
output channel, AppCenter routes each track exclusively to its matching output channel. The following
illustration shows one example of how unique labels are evaluated.
