The GMask node accesses the Garbage Mask menu and includes the Tracer and Region of Interest (ROI) functions. The GMask node accepts a front and a matte clip as input.
GMask node tabs process gaps in clips set to No Media as black frames. An unconnected front clip will return an error, while an unconnected back clip will process black frames.
This node accepts floating-point (OpenEXR) input. However, the Stabilizer and pickers are disabled when this type of input is attached to the node. Pickers in a pre-existing mask will be converted to an advanced gradient.
You can save and load GMask setups directly in Batch. See Loading Garbage Mask Setups and Saving Garbage Mask Setups.
