lets you retime all of the keyframes that are applied to that rotoshape.
Using this command, you can compress the keyframes that are animating a rotoshape,
speeding up the changes taking place from keyframe to keyframe, or expand them,
slowing the animation down.
When you click retimeShapes, the Node Retime window appears. The retimeShapes
command has two modes, Speed and Remap, which affect a RotoShape node’s
keyframes similarly to the Speed and Remap options found within the Timing tab of a
FileIn node.
Speed Adjustments
The default Operation, Speed, lets you compress or expand all of the keyframes within
the RotoShape node by a fixed multiplier.
