maybe try it out and see how it goes.. IF you are struggling you can just upload what you have to youtube so i can grab it and help....
This is the one I have on my PC and I really like it. You have to put up with a water-mark until you upgrade. Thinks it's reasonable price for what you get. Just wasn't sure if there was a free movie editor that I had missed. Happy to use this software. I will be in touch, buddy.
