Video cameras that I have used have the option to turn on what they refer to as zebra patterns (not sure what Canon calls them). With a 5dm3:
1. How do you turn on this pattern to check for overexposed parts of an image?
2. If I'm shooting in AV mode and setting the aperture and ISO, and parts of my image display the pattern indicating some parts are overexposed, is this what adjusting the metering is for, to adjust it a bit so some parts are not overexposed?
