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?

Thanks.

Not sure about "Zebra Patterns"...Use the Histogram (and detailed image review) to check for over- under- exposure and correct these problems (if any) using exposure compensation.

Keep your eye on the magic lantern firmware option - it will give your zebra stripes when it comes out for the 5D3.

For #1 I think what the OP is talking about is where it flashes the overexposed area. It's obviously not a zebra pattern, but quite handy when looking for blown out highlights.

I don't have my camera at work now, and for the life of me I can't remember what it's called. :(

#2, simply, yes. If you have overexposed parts, then you can adjust for a lower exposure. You might want to brush up on exposure if you are struggling with it. Understanding Exposure by Bryan Peterson is a great book to start with. (or check out some basic exposure videos)

I think this is what you are referring to. The technical term is Highlight Alert but is commonly called the Blinkies. It is set in the Camera 3 (red) tab of the menu. I haven't tried this in video, but it works for still images.

I'd rather have a bottle in front of me than a frontal lobotomy.

Is this question regarding 5D3 video or stills? Because I don't think there's highlight alert for video... which I think is why Todd Lambert mentioned Magic Lantern.

I don't think there is any way to do thisexternal link with the Canon DSLRs, but you can turn on the "blinkies" for still photos.
