TimeWarp

Lets you slow down, speed up, or even reverse selected frames in a clip without necessarily altering its overall length.

Inputs and Controls

Connection Type

Connection Name

Function

Input

unnamed

The sequence to warp.

Note:  When you connect the TimeWarp node, frame 1 is automatically keyframed as the first frame.

Knob (Scripting)

Default Value

Function

TimeWarp Tab

input frame

lookup

1

Sets which frame of the input sequence appears at the current frame.

For example, you could set frame 10 of the input to output at frame 5, effectively doubling the speed of the sequence.

input length

length

1

Sets the length of time to average together to produce the output frame.

Click the set to df/dt button to automatically set the inputlength to the correct formula based on the derivative of the inputframe.

Sets the type of filtering to apply to the time warp:

• none - passes fractional frame numbers to the input, which is useful if the input can calculate its own frame interpolation.

• nearest - rounds the center of the range to nearest integer frame.

• box - uses a weighted average of several frames together to cover the output range.
