I bought Studio 7 Deluxe about 3 years ago, as I wanted to get our video 8 analog onto a digital format. I made about 2 hours of nearly finished and edited video. I didn't get back to it to try to finish it until a few months later. I was lost at trying to pick up where I had left off. Nevertheless, I have not gotten back to finalize it and I believe compress it. It still takes up about 70 gigs of my 80 gig hard drive. Would it be any easier to get back on track with finishing this by upgrading to Studio 9 Deluxe? Can I upgrade from 7 to 9, or do I have to have an '8' first? It also came with the FX and a couple of other programs I can't remember.
