Thusfar, I have compliled the video, cut the scenes, and moved them into an order I like. In other words, its no longer the original rough footage, but an "edited" video file. What I hope is that,with this software you mentioned, I can simply import the finished video file and simply add a soundtrack I will be able to similarly edit (i.e. adjust volume during different scenes as well as cut songs before they end, as I mentioned above). As the software seems to incorporate MyDVD as well (if I understood correctly), then I assume this should not be a problem, but I just thought to ask.
I guess what I'm afraid of (to put it a different way) is that I get the software, and the video file I've spent a few days working on is not able to be imported onto the new software in order to manipulate its audio. I don't want to have to import the raw footage and start over!
Hope this clarifies what I mean! Thanks for all your help by the way!
