Mixing different digital cameras in the same movie For my next movie, I want to have a second camera to record a different angle. My main camera is a mid-range Canon DSLR and I was planning to buy a second, cheaper DSLR. Would it be possible to see the difference between the two cameras in the finished movie? I'm guessing that the number of megapixels would make a difference if they are not the same.

Would a Nikon 1 or Canon Powershot or equivalent higher-end compact work?
HD 1080 video is only 2 megapixels, so the camera full size rating would not be an issue for video.  You have to put all of the video clips together in a video editor of course, which should not any issue.  I would shoot with both cameras at the same settings, like 30p. 

There is always a possibly of slight color/tint differences in two cameras.  Probably not noticeable on different scenes, but different views of the same scene possibly might notice? The video editor should allow correction in some degree even it does show.
