Hi, I have a long video (one hour) which I need to split into separate clips, to add individually to slides in PowerPoint. But I cant see (despite hours of YouTube and the help in MovieMaker) on how to do it.  I can see how to split videos and trim them, but what I need to do is cut this long video into clips and be able to save each one with a different file name. I am using Windows 7 with Office 2010 and Windows 8 / 2013. Some Help files refer to editing lables I do not see showing in the versions I am using.  Thanks.  David
