[Chris Huggett] “Sorry Bob, i seemed to miss the bit where you captured the footage.
Was it off a Digi Beta or off an digital audio tape?”
My situation differs from yours in that I create the surround sound effect from multiple mono audio tracks, inside Premiere Pro. I start with stereo audio and add audio tracks inside Premiere Pro. I’m guessing that your project may actually be easier as you already have the various audio tracks. If you have Premiere Pro with capture capability, but can’t capture all five audio channels at the same time, just digitize multiple passes of your video/audio and sync them up inside Premiere Pro. Then assign the audio tracks their proper locations (frontleft/frontcenter/frontright/rearleft/rearright) with the Premiere Pro mixer, use the Surcode encoder, and you’re done.
I apologize for my answer; it was way too specific, and tied to my particular situation, but I was trying to answer you quickly, so I just copied my notes-to-self about the workflow. (I wrote those notes because I figured it would be a while before another 5.1 project came up and I didn’t want to forget!) My workflow is a bit cumbersome, because (1) I still edit on my great old discreet edit* NLE rather than my crippled Premiere Pro system, which has no capture card (waiting to afford Axio), and (2) I opted for the less expensive Digital Rapids card, which does not have machine control and therefore the easiest way to keep video and audio in sync is to encode them together. (I could use a beep/flashframe and avoid the whole audio encode/conversion step by syncing up the audio and video inside Premiere Pro.)
