Add marks the last frame of the scene.
Add marks the last field of the scene.
With edited material the scenes will normally be cut with a F1
dominance. So the Platinum event will mark F2 as the last field of the
scene.
With cut 24fps film on 30fps tape, there will be a 2:3 sequence and the
events will end on different fields.
To help mark events correctly there is an Add Tape Event selection in the User controls.
There are four choices.
