Im looking to create a few videos with the 5d3. My question is, when Im in Adobe Premiere I would like it to have the crop with the black bars on top and bottom(2.35:1 crop) To get this crop, I must export with width=1440 and height=1080. When this is done, part of the video gets chopped off. My question is, is there any way in the 5d3 while recording video to set this standard so I can get the correct shot? I notice that while recording video on the 5d3 there is black bars on the top and bottom. is there a way to show what these black bars would like like with the 2.35:1 crop IN camera instead of just guessing how wide to record?
