Shift compositing node

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.

Relative Shift

Shifts the amount specified by the Shift Value.

Shift Start to Shift Value

Starts at the point specified by Shift Value.

Shift End to Shift Value

Shifts the image sequence such that it ends at the point specified by the Shift Value.

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.

Align Start with 2nd Input’s Start: Align End with 2nd Input’s End: Shift To Precede 2nd Input: Shift To Follow 2nd Input:

Shift Value

The amount to shift by, in either frames or seconds.

Units

The shift units, either Frames or Seconds.
