The Add Pulldown and Remove Pulldown nodes each accept a front clip as input:
When either the Add Pulldown or Remove Pulldown nodes render a transition, preceding and subsequent frames with no media are replaced by black frames, regardless of Media settings for the missing media.
The First Processed Frame field sets the value at which output is processed from the node. Unprocessed output does not display any media.
These nodes also support floating-point clip input.
