Hi, I need some basic help constructing a "Demo" video from a 90min live music show. The file I'm working with is one 7 gig .wav file that someone else already edited with different camera angles, audio, etc. I'd like to take say ten 20 second snippets, and put them together. I've done this before with Videopad, but it was always a painful process, as I don't think I was doing it correctly, or efficiently. My first step is to cut the snippets, then have them at my disposal to put together to form the final "demo" vid. How do I do this most efficiently? I think in the past I would literally export each snippet, then start a whole new project, importing them all. Thanks in advance for the help!
