Adds a black matte to the frame. Use this if you filmed using a 360 camera but only want to use part of the 360 image - for example if you and the film crew occupy the 90 degrees behind the camera.

Vertical
- Start: half the height of the field-of-view in degrees of the un-matted area.
- End: half the height of the field-of-view in degrees where the matte is at 100%.
