# Master Keyer Node

Use the Master Keyer node to gesturally pull a key. Add a Master Keyer node to the Batch pipeline when you need to create an accurate key of a clip. Use the Master Keyer node to automatically suppress colour spill, to colour correct, and to remove noise or grain. See About the Keyer.

The Master Keyer node accepts front, back, and matte clips as input. While there is no setup menu for the Master Keyer node, it can be saved as part of the Batch setup, or alternatively, as a Custom node. The Master Keyer is also available from the Keyer node.

Select an output type from the Select Output box.

TipIn order for the hotkeys M and D to correspond to Matte and Degrain, the Master Keyer in Batch must have focus and the viewport cannot be set to a schematic view. If the schematic has focus, then M corresponds to Move and D corresponds to Delete.

The Master Keyer node processes gaps in clips set to No Media based on the input tab receiving the information.
