why are my iPhone4 videos different in size? Some videos I take are square and 640 x 480, while others are 1920 x 1080, data rate changes with size as well, so quality is much better on the larger size - seems to be random - how do i set the size so all vids record the same? preferably the larger size.
Recording videos with Instagram will save them in the lower resolution. To record at native resolution, use the Camera app.
