About the Compositor and Optics
 
 
 

Use the Compositor to create a composite while controlling cropping, softness, and camera, or use Quick Composite to composite quickly without these features. After creating a composite, use Optics to apply glow effects.

You can composite a front clip, a back clip, and a matte clip. The Compositor is similar to Action except that it only supports one layer and does not provide access to the Keyer. You can scale, rotate, translate, or shear the front clip in two dimensions. You can create animations in the Compositor, apply motion paths to the front clip and the camera in the scene, as well as move and animate the camera-eye position. In addition, you can colour correct all three clips, and track points on the back clip.

Use the Quick Composite for one-step compositing of a front, back, and matte clip. Use Optics to create a glow effect in the composite. These tools are most useful in Batch for finishing effects when you have already generated mattes and fine-tuned the clips. See Batch Processing.
