Discussion

A value of kFxTimeBase_TIMELINE means that times are absolute frame numbers, where zero is the start of the timeline. A value of kFxTimeBase_CLIP indicates that times are "clip-relative," meaning that zero is the start of the "clip." For generators and transitions, the clip is the effect itself. For filters, the clip is the video item to which the filter is applied.
