I've been starting to dabble with playing with different aspect ratios of my final out put for video. I'm wondering, when you're using a 5D3, what are your best methods to use to make sure you frame the composition in a manner that makes sure you have all your content in frame?
It sure would be cool, if there was a button on the camera that would put the black bars where the 'crop' would be given various aspect ratios that might be used.
What do ya'll do when wanting to make sure your composition is framed properly when you want to use something other than 16:9 ?
Thanks in advance,
