Quick Compositing

Overview

All FrameCycler products and SpeedGrade XR, SpeedGrade DI allow for quick compositing. You can stack files with an alpha channel on top of any other kind of footage on the timeline. The result will be a mixdown of both images. This technology can also be used with MetaRender to create frame sequence or movie file output from multiple layers of footage that includes alpha channels.
