Its a 5d mark III. The problem I'm having is the current crop marks are centered. I deliver a documentary edit of the ceremony and reception in 16x9, and a feature film in cinemescope. The problem is that I frame everything for cinemescope and I get too much head room when I cut the documentary edit. If the crop is on the top, then it will always be framed correctly no matter if you deliver 2.35 or 16x9. You just shift the image down in post.
