8 Channel MXF preset I made suddenly only outputting to first two tracks

Posted by Art Carmichael on January 11, 2018 at 2:34 am

I made this preset last June to output 8 channel MXFs of my spots per our International team’s specs so, they can use the audio tracks that make sense for whichever market they happen to be repackaging my spots for:

(video)

(audio)

That used to work fine with the sequence settings I created in Premiere for my International deliverables:

(pic. 1 – general)

(pic. 2 – general)

(settings)

(tracks)

This worked great until my latest International output, last week. I got a call from International today to say, the MXFs I delivered only had the stereo mixes with no split tracks. I pulled them in, sure enough, they had 8 channels but only channels 1 & 2 had audio.

Here’s what the sequence looks like when I output from Premiere to Media Encoder:

(output sequence)

Here’s what it looks like when I import the MXFs I create with the above settings back into Premiere; creating a new sequence from the imported clip):

As you can see the split audio is there on the output sequence but only channels 1 & 2 have audio in the MXFs I created using the above method. What baffles me is that this worked fine until my last output.

For the life of me, I can’t seem to figure out what changed and how to fix this.

I’m using Premiere Pro version 12.0 (build 224) & Media Encoder version 12.0 (build 202).

Here are my computer specs:

Any thoughts?

Oh, and here are the specs required by our International team:

Thanks!

P.S. I will cross post this in the Media Encoder forum.

If you check your first screencap it actually says the source is stereo. Have you assigned the tracks to the correct track numbers?

Gah! When I saw your post I was thinking, yes! That has to be it! My preset somehow reverted back to stereo. Unfortunately, when I changed it back to multichannel:

I got the same result – 8 channels but only channels 1 & 2 contained audio :~(

You have a multichannel sequence, but do you have each track mapped to a different channel or are they all set to 1-2 (the default setting)?

You can change the mapping easily in the Track mixer or in a somewhat more cumbersome way in the timeline
