FreeformRegion

The region of the scene that you want to monitor. Use this parameter if the region of interest is a shape other than a rectangle. To define a rectangular region, set the Region parameter instead.

Specify a list of points (at least three) followed by the units that you want to use. The top-left pixel has the coordinates 0,0 (x-coordinates represent the distance from the left side of the frame and y-coordinates represent the distance from the top of the frame). You can separate points and coordinates with commas or spaces. For example:

FreeformRegion=x1,y1 x2,y2 ...xn,yn units.

You can choose the following units:

  • percent or % to use percentages of the image or video dimensions (x-coordinates as percentages of the width, y-coordinates as percentages of the height).
  • pixels or px to use numbers of pixels.
