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 will be used as an example.

For all examples VideoPort = A

  • CUE_TAIL: Viz Mosart will recue the cued clip at a specific time (in seconds)

    • Parameter: -15 (negative value) - configurable. Viz Mosart will cue at the start of the last 15 seconds of the clip (the clip will have 15 seconds left to play plus Post roll)

    • Parameter: 15 (positive value) - configurable. Viz Mosart will cue 15 seconds into the clip

Video Port Groups

It is also possible to use the video port group names (A/B, C/D...). If a group is found it will by default get 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 will be recued to be ready to play the last 10 seconds of the clip.
