Use Glow to create and customize a glow effect on a clip.
To access the Glow menu, use:
Batch, then select a node from the Node bin.
Timeline, then use Batch FX (see Creating Batch FX).
Tools, then select from the menu (See Accessing Tools).
The Modular Keyer, then select a node from the Node bin.
This node accepts a front and matte clip, and outputs a result an outmatte. You can add a Glow node to any part of the pipeline except to the Front and Matte pipes of MBLend nodes and the Matte pipes of CBlend nodes.
