Shifts an image sequence in time.
This operation shifts an image sequence in time. An optional second input can be used as a reference, so that this sequence becomes 'linked' to the start or end of the reference sequence and shifts if they change.
This operation does not use any cache memory.
Note
This operators parameters can not be animated (as they affect time).
Parameters
| Shift Method | Sequences can be shifted in several ways if no reference input is connected.
| ||||||
| Input Shift | If a reference input is connected, several different ways of linking the two sequences together can be used. The sequence will always follow any changes in the reference sequence’s start or end time.
| ||||||
| Shift Value | The amount to shift by, in either frames or seconds. | ||||||
| Units | The shift units, either Frames or Seconds. |
