Defining the DeGrain and ReGrain Area

You can use a crop box to apply DeGrain and ReGrain processes to a specific region of the front clip rather than the entire clip. Because grain management is typically performed when you work with high-resolution film clips, using the crop box can greatly increase interactivity while setting DeGrain and ReGrain parameters.

To define the DeGrain and ReGrain area:

1. In the DeGrain or ReGrain menu, enable Crop.
2. Drag a selection box over the image to define the specific region inside which you want the DeGrain or ReGrain process to be applied.
3. To change the position or size of the crop box, drag a new selection box.

   The new crop box replaces the previous one. The clip can now be processed from Batch (the crop box does not affect clip processing from the desktop).

   NoteTo apply the DeGrain or ReGrain process to the entire clip, disable Crop.
