Outputting 4 Channel Audio

[Russell Lasson]

So tristan004,

Did you get it figured out?

[Tristan004]

Hi all!

Thanks to everybody for the input! I just got back in to work and will be trying it out momentarily. I’ll post the results in a few minutes.

Okay – phase one complete. I’ve set up the audio and mapped it to all 4 channels from the sequence control panel. The decks are seeing all four channels.

First q- what I had to do to get FCP to send out mono mixes of the program’s audio to BOTH channel 3 AND 4 was to export an .aiff file (converted into mono), reimport it, and then drop it onto TWO layers, assigning one layer to channel 3 and the other to channel 4. Is that the simplist way?

Second q – is there a way to export a QT movie with this same configuration (1&2 Stereo, 3&4 both mono)?

q1 – So you had a stereo mix that you wanted to send mono out to channels 3 and 4? Okay, it’s not making sense to me why you would want to do that, but there is an easier way.

a1 – Duplicate the stereo file so that it takes up 4 tracks. Map both tracks of the first file to output track 3 and map both tracks of the second file to track 4. In doing this it is possible that your audio might start clipping because you’re adding two volumes together, so it is “best practices” to go to Mark – Audio Peaks – Mark. It will take a little while, but you can’t have audio clipping on your tape so it’s worth it (or you’ll just have to do it over later when someone gets the tape and says, “Hey, the audio’s clipping. Make me a new tape!”)

q2 – Exporting QuickTime with multiple channels of audio

a2 – Yes, file – export – quicktime movie. You just need to have the audio mapped right, like you do.

You want the same sound to Channel 3 and 4? Just duplicate the audio track in 3 to Channel 4. Make a Stereo Pair or leave the audio split.
