Just started using this software. Sorry if I'm not in the right section even the forum is new for me. What I want to do is take a few minutes here and there out a 2 hour video to make a 3 minute video. I'm not even sure I'd be able to get back to this area to find out some answers unless they are also posted to my email. I can snip a few minutes off at the end and join full videos but I'm having trouble with the start and end snips right now. I don't know the lingo so I don't even know how to look up help....thanks for any suggestions and help/
