# Degrain and Regrain Nodes

Use the Degrain and Regrain nodes to add and remove grain from the RGB channels of a selected colour in an image. The Degrain and Regrain nodes are the same as the Degrain and Regrain commands in the Film menu.

The Degrain node accepts only a front clip as input. The Regrain node accepts front, back, and matte clips as input.

The Regrain node Image Type box adjusts the algorithm based on the Image Data Type of your media. See Adjusting Algorithms Based on Image Data Type.

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

Input | Result

Front | No media
Back | Black frames
