Search TipsAdjustBBox
The AdjustBBox node lets you expand or crop the edges of the bounding box by a specified number of pixels. The bounding box defines the area of the frame that Nuke sees as having valid image data. For example, if you have an image with lots of black (0,0,0,0), you can adjust the bounding box to contain just the useful area so that Nuke won’t waste time computing results where there is no change.
