Video Port Keyboard Shortcuts
To be able to use the video port control commands, you need to add a set of shortcuts for each video port. You have to create a new set for each video port A, B, C etc. Here port A is used as an example.

Video Port Groups
It is also possible to use the video port group names (A/B, C/D...). If a group is found it by default gets the next port. If you want the current port, you have to add “CURRENT” to the Parameter field. If you want to have additional parameters for the Action, you can add it after the CURRENT term separated by comma.
Examples
In this example, the cued port in the group is recued to be ready to play the last ten seconds of the clip.
In this example, the playing port is paused.
Control On Air or Preview Video Port
It is also possible to make commands to control the video port that is currently On Air or in preview. Just type ONAIR in the VideoPort field to direct the command to the On Air port.
To control the port in preview, use PREVIEW in the VideoPort field. In this example, the video port in preview recues to be ready to play the last ten seconds of the clip.
Video Port Error Messages
If AV Automation is unable to execute the command, an error message displays (e.g. Failed to get VIDEO_PORT using ‘c/d’).
Note: For configuration guidelines, refer to the Viz Mosart Administrator Guide, topic Control Commands in Templates, section VIDEO_PORT Control Commands in AV Automation Template Properties.
