If you can get a consumer camera that shoots HD for just a couple hundred bucks, why not load up on the cameras and get multiple angles of an event for next to no cost. Plus, you can move them around easily, perch them in unusual places and you don’t need a half-dozen video camera operators. Sounds great, doesn’t it?
Well, the reality is that the rolling shutter CMOS image distortion in video cameras is just as prevalent in digital still cameras. You can easily see it when you bounce the camera up and down lightly, or pan the camera side to side. Things that you naturally do when you are recording video with the camera in your hands instead of on a tripod. These motions distort the image from what really exists in reality. Camera flashes are partially bad- partially illuminating multiple frames. When you play that back, it looks completely unnatural.
To quantify these CMOS distortions, I secured two brand new digital still cameras that shoot HD video and pitted them side by side in some critical tests and the results clearly demonstrate the difference between CMOS and CCD when it comes to capturing video that faithfully represents what happened.
