Protocol

FxTemporalTransitionImageAPI

The FxTemporalTransitionImageAPI protocol defines the methods the host application provides to access an input image at a specific time from a transition.

Declaration

@protocol FxTemporalTransitionImageAPI

Overview

The only plug-ins that need to use this host protocol are transition plug-ins that do "retiming,". That is, a filter whose output depends on input frames at times other than the output time.
