When multiple shots overlap in different tracks, the uppermost shot is used during scene evaluation.
To move shots
Sequence times are intended to be integers. In cases where the shot scale would create a non-integer duration, the scale value is altered slightly to ensure integer duration.
The lower two numbers displayed on a shot represent the sequence start and end times. The upper two numbers represent the Maya start and end times for the shot.
Clips stay in sync when you move the associated shot.
