You can add sound to video in any number of programs -- Premiere, After Effects, Video Wave, Sonic Foundry's Acid, etc. If you're really wanting to do detailed sound work, Premiere will allow for many layers of sound (very important for adding dialogue, sound effects, music, ambience, etc), and you can hear the sound as you play the movie in the project window (as opposed to having to render the movie out to hear the sound synched with the picture). Though After Effects handles sound clips, it doesn't do it in real time, so while you're animating a laser or comping a ship into a scene, you're still left to imagining the sound or making whooshing sounds as the ship flies by. (Even the "big boys" [and girls] do this kind of thing -- making zapping noises for phasers with their mouths before the sound department gets the clip.) By the way -- vhigh -- where do you get Sonic Forge? I've never heard of it, unless you mean Sound Forge by Sonic Foundry?
