I'm trying to make a three-channel video for an art exhibition, 3 projectors playing at once, synchronized for the final output...but I am not quite sure how to edit this in premiere and there are not so many resources available. For now I have the 3 videos on 3 separate video tracks and the audio on corresponding 3 audio tracks. I don't know how this should be exported to be 3 channels...does anyone have experience with this sort of thing?
I don't think any program for playback would seprate the the audio and video tracks. I think you would have to dissable and enable the tracks as needed and render them out. You coud do a picture in picture for the video tracks.
