Old network
As of Houdini 20.5, use Copernicus nodes instead of Compositing nodes. Though both networks still exist, the Compositing network is now designated as COP Network - Old. The Compositing network and its nodes will be deprecated and then removed in a future Houdini release.
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 operator’s 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
Make the output sequence start at the same time as the sequence attached to input #2.
Align End with 2nd Input’s End
Make the output sequence end at the same time as the sequence attached to input #2.
Shift To Precede 2nd Input
Output sequence will end on the frame just before the second input starts.
Shift To Follow 2nd Input
Output sequence will start on the frame after 2nd input ends.
Shift Value
The amount to shift by, in either frames or seconds.
Units
The shift units, either Frames or Seconds.
