How I cropped the images

So once my videos were compressed and flipped so they could be presented well .I wanted to show How I did this so this required screen shots however , I felt uploading the whole screen image was not necessary  when discussing the flipping of the video .

So I used http://www.picresize.com/ this allows you to resize , crop and Edit your pictures for free , I found the cropping very useful as it was user friendly and It was a free online service which does not save you pictures so this is always useful finically and securcity wise
