    I was just wondering if anyone get this "gelatin" effect when moving their iPod Touch side to side, while recording. It almost look like a gelatin when u shake it. It usually happens when theirs a lot of stuff going on, something with a lot texture. Here's a video as a quick example:

    This is because the iPod touch (iPhone and other devices) have rolling shutter. What that means, is instead of taking 30 still frames and put them in order, it constanly scrolling down. So the top line is 1/30th of a second before the bottom. So the next frame just picks up right where the bottom line left off. So fast moving objects get stretched out as the camera records the action all in one frame as it scans down

    It's not really a problem in the sense that this is they way the camera is expected to work- it's by design. To fix it would require a different camera altogether.
