does blender have a way to visualize crop marks? I shot video in 1080p and will shoot some at 720p @60fps soon, All shots will be taken with a cinemascope crop mark on a t3i with ML, the videos are for VFX renders and I may want to reframe some shots or use the extra real estate to simulate additional camera motion, so it will be very useful to always know where my “mark” is in blender.
