Use the Output node to output clips to the Desktop, a clip library, or a remote framestore. The Output node accepts video input from clips with video tracks and audio input from clips with audio tracks.
You can process both RGB-A clips and clips containing stereo tracks with an Output node. In RGB-A processing mode, the Output node accepts a front input and a matte input. The front is output as the RGB result and the matte is output as the alpha result.
