First of all, I'm new in the world of video editing. I got myself a copy of Adobe Premiere CS3 and I'm trying to figure out how this stuff works. The first thing I'm trying to do is to put several .AVI clips I have together in another .AVI file, so after dragging the clips to the time bar in the bottom, I hit "export" and choose to save it in AVI format. The thing is that this operation takes almost two hours! The final clip is only 18 minutes long. Shouldn't it take much shorter, given that the only thing I'm doing is joining seven AVI clips into one?
