PiP Exit Transition Duration

Overrides the exit transition duration for a picture-in-picture overlay. When set, this takes precedence over video-mark-transition-dur for the exit only, while the entrance continues to use -dur or its own video-mark-transition-in-dur override.

video-mark-transition-out-dur accepts a float in seconds from 0 to 60. Use video-mark-transition-out-dur[N] for a specific overlay layer.

Requires an exit transition type to be set via video-mark-transition or video-mark-transition-out. Requires video-mark-end to be set.
