Modifying Extrapolation
 
 
 

Extrapolation is used to determine the behavior of a channel before the first, or after the last, keyframe. Extrapolation is useful when you want to create a cyclical effect, such as shutter flicker (as you would find in an old-time movie). You create one period in the flicker cycle, then use extrapolation to repeat the period over and over again. You will see the effects of extrapolation only if the film image has frames before the first keyframe or after the last keyframe.

The following extrapolation types are supported:
