From try to experiment with our filming we hit a few problems using the programe 'Animater d.v' this is  free programe and had good feeback on the website. the problems that we had at first that even though we were only takeing two frames per second, we found that when we played it back that it would fast forward really fast. we tried to concore this problem by taking more frames. This would have worked if the programe then didnt keep freezer. every time we would go to use this computer there would be a fresh problem with the programe. We then  decided to change programes to 'stop motion pro' we have only tried the free trial. So far. So good.
