Garbage Mask

Use the Garbage Mask to isolate particular areas of an image to include with, or exclude from, the opaque area of the matte.

To access the Garbage Mask menu, use:

• Batch, then select a node from the Node bin.

• Timeline, then use Batch FX (see Creating Batch FX).

• Timeline, then add Timeline FX from the Effects ribbon (see Adding Timeline FX).

  When you access the GMask as a Timeline FX, you can enable Use Matte to use the matte input as part of the effect processing.

• Tools, then select from the menu (See Accessing Tools).

• The Modular Keyer, then select a node from the Node bin.

Note: A different GMask node is available from within Action and the Mask Tracer.

This node accepts a front and a matte clip as input, and outputs a result.

GMask usage notes:

• The Garbage Mask menu includes the Tracer and the region of Interest (ROI) functions, which can also be found in the Modular Keyer.
• The node processes gaps in clips set to No Media as black frames. An unconnected front clip will return an error, while and unconnected back clip will process black frames.
• You can save and load GMask setups directly in Batch or Batch FX.
