Use Blur to apply and customize a blur filter to a clip.

You can access the Blur effect in the following ways:

• As a Batch node. This node accepts a front clip and a matte clip, and outputs a result and output matte clip. The output matte clip can have a different level of blur than the result clip.
• As a Modular Keyer node. You can add a Blur node to any part of the pipeline except to the Front and Matte pipes of MBlend nodes and the Matte pipes of CBlend nodes.
