Question about t4i video resolution
I recently purchased a t4i as an upgrade to my xti and I'm liking everything about it. My question is about video resolutions; it lets you pick from 1920x1080, 1280x720, and then ... 640x480?
I don't need to shoot HD quality video (and don't want the burden of keeping around all the HD content). So SD is fine for me, but why not 850x480 (or whatever the 16:9 equivalent is)? Is there anything I can do to get 480p (in the camera instead of post processed)?
