I have done this and I seem to recall that I scaled the image before cropping. This worked pretty well for me, but I did zooms on the slow side. Try scaling the image up by the appropriate amount and cutting the next frame out of the new, larger image. Also make sure that each frame is made by rescaling the original, rather than the previous frame. Edward
