This is a python script for Nuke to retime roto shapes. It supports shapes only, not strokes, not opensplines.
It works by looping through each roto node, each shape in the roto node, and each point on the shape. It creates an expression on each point referencing a frame_lookup knob. Put a retime curve on this knob and your shapes will be retimed.

Hey @LewieFX,
It's been a while since I looked at this. If I recall correctly, and by looking at the code I believe the intended use is to run this script on a roto node. It will loop through all the shapes and add an expression so that the timing of the animation is controlled by the frame lookup knob. The idea is to retime the roto shapes themselves instead of trying to retime the image that the roto node generates, which will usually result in artifacts. This is most applicable for shots with retimes.
So for this to work you would need to put whatever retime curve animation into the frame lookup knob. Does it make sense?

That does make sense but seems like its not working for my shot. It seems to have it some frames but then loses it on others. Would baked tracks in roto layers be effecting it?

After coming back, and testing this it seems like it doesn't like tracking data being in the roto layer. Looks like it results in some adding of values and therefore offsetting the shape.
Hey Jed,
I am a bit confused how to use this. I run the script selecting my roto nodes and it works but with no expression in the frame lookup tab. I am not sure how i am meant to use this script. Could you please help?
