I had no homework to do really and my friend needed to focus so I told her that she has to do her work for at least 30 minutes straight so we will both benefit I would get video of someone doing work and she will do her work. A win win situation . So all I did was record her got in way in the beginning and then just sped it up in movie maker. I do not know why it looks all choppy though I think it is my computer is just slow or does it do it on all of them?
