Combine Retimes is a python script that can combines a stack of multiple retiming nodes into a single output (both a lookup table and a speed value).It supports: Retime, TimeWarp, Kronos, OFlow, TimeOffset and FrameHold.
In addition, it also supports Switch and Dissolve nodes in the stack, although because of its nature take the later with a pinch of salt.
This script does not require installation and can be executed directly from the Nuke's Script Editor.
