I'm working on a project, the output is 2K, 2048 X 1152. I have files from Canon 5D MKII, GoProp, and RED, How do I resize the the 5D MKII to match the RED? The RED files are 4480 X 1920 and are letter box, the 5DMKII ar 1920 X 1080, and ill the frame, How to I letter box them.
go to Color> output blanking > 1:2.35 in the menus at the top is the quickest way
This will give you a wide screen frame at almost the same as your RED (which is 1:2.33). The it will crop the Canon stuff to that ratio too when you resize to the full frame size. (the red too a tiny bit)
If it has to be 1:2.33 and NOT 1:2.35 go to the sizing menu at the bottom select output sizing from the dropdown on the right then select BLANKING on the left. Then blank out 137 from top and bottom
