Can Magic Lantern be configured to remove all overlays (like crop marks) from my video when sent over HDMI? Using just the Info. button (no Magic Lantern), I can remove everything except crop marks. I'd like to use the camera as a web cam, so they'd be annoying. I can remove them using Canon's web cam utility (which works over USB), but that restricts me to a 4:3 aspect ratio. Thanks for any tips.
