The Begin Sequence Render Action

	#include "ofxImageEffect.h"
	#define kOfxImageEffectActionBeginSequenceRender   "OfxImageEffectActionBeginSequenceRender"


This action is passed to an image effect before it renders a range of frames. It is there to allow an effect to set things up for a long sequence of frames. Note that this is still called, even if only a single frame is being rendered in an interactive environment.


  • kOfxActionCreateInstance has been called on the instance


  • kOfxImageEffectActionRender action will be called at least once on the instance
  • kOfxImageEffectActionEndSequenceRender action will be called on the instance

Return Values

  • kOfxStatOK, the action was trapped and handled cleanly by the effect,
  • kOfxStatReplyDefault, the action was not trapped, but all is well anyway,
  • kOfxStatErrMemory, in which case the action may be called again after a memory purge,
  • kOfxStatFailed, something wrong, but no error code appropriate, plugin to post message,
  • kOfxStatErrFatal
