Sorry if I am asking a stupid question here: I need to video over an hour of continuous footage on my iPad 2. But when I tried to do this using the rear camera, the camera stopped at 49 minutes. The file size is 3.69GB. I still had plenty of battery and memory left and was able to film new clips. Can someone tell me if there is a way to record for longer than 49 minutes continuously? Is the file size too big? Thank-you.
