H Crop: Will produce a horizontally stretched effect on the image; transforms
anamorphic SD to full frame
SD Pillarbox: Will produce an image in the center of the screen with black borders on the
left and right sides and an anamorphized image in the center
V Crop: Will transform SD letterbox material to an anamorphic image
