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 stretches or compresses a sequence in time. Frames are either dropped, doubled or interpolated. If interpolation is not used, this operation will not use any cache memory.
Parameters ¶
Scale Method
Select a method for changing the timing.
Modify Sequence Length Only
Changes the length of the sequence without changing the frame rate; the sequence will be longer or shorter in time.
Modify Sequence Length, Same Time Span
Changes the length of the sequence Time Span and adjusts the frame rate so the sequence is the same time length.
Modify Frame Rate Only
Only changes the frame rate. The sequence becomes longer or shorter, but the number of frames stays the same.
Modify Frame Rate, Same Time Span
Changes the frame rate and increases Span or decreases the number of frames to keep the sequence the same time length.
Interpolation
When increasing or decreasing the number of frames in the sequence, this parameter determines the frame(s) to use for the output frames.
Previous Frame
Uses the input frame exactly at or before the time of the output frame.
Closest Frame
Uses the input frame exactly at or closest to the time of the output frame.
Next Frame
Uses the input frame exactly at or after the time of the output frame.
Blend Nearest Frames
Picks the 2 closest frames and linearly blends them together, weighting them with how close each input frames' time is to the output frame.
Frame Rate
The frame rate, for methods that require it.
Length Method
Specifies how to change the length of the sequence, for Scale Methods that require it (see below).
Length Scale
Changes the length of the sequence by a scale factor. Scales greater than 1 increase the length, scales less than 1 decrease it.
Sequence Length
Specifies the new length of the sequence, in frames.
Length Difference
Specifies how many frames to add or subtract from the input sequence length.
