This is in response to your post under "Demo Reel Intro" But I thought I'd copy it here as well. I used Avid DV Express 3.5 to edit the images as well as the sound. It can do unlimited layers of sound but you will be able to only hear 8 of them at a time. You just do a mixdown. There were around 19 or 20 tracks of sound. I used Cool Edit to manipulate the sound effects. I would reccommend using Adobe Premiere or Vegas video to help you assemble the project They tend to be a little more user friendly. Avid can do alot but takes a bit of time to get the hang of.
