Configuration Section: TaskName
Example:
Region=50,20,800,400
RegionUnit=pixel

In this example, the top-left corner of the region of interest is 50 pixels from the left side of the frame and 20 pixels from the top of the frame. The region is 800 pixels wide and 400 pixels high.

Region=25,0,50,100
RegionUnit=percent

In this example, the region of interest covers the central 50% of the width of the frame, and the entire height of the frame.
