Exporting audio for QC – Mixing together???

[David Roth weiss]

Instead of exporting video and eight track together, just export each audio track as its own as a separate file. Export a temp mix tied to the video so you have a guide track, if necessary, then reassemble them as required at the mix, and mute the guide tracks once you are sure everything is synced properly.

[David Roth Weiss] “then reassemble them as required at the mix”

Sorry, what? At what mix?

The OP has 8 separate tracks, each 5.1 track as mono, and Stereo L and R as mono…and wants to export a file with all those as separate tracks. I do this all the time in Avid and Resolve, as it is a required output type. And it LOOKS like it should work given his settings, but it isn’t.

Hmmm…I might have to see what I can figure out…I havne’t had to delivery from PPro in this manner yet.

Oops!!! I missed the whole part about it being 5.1 surround with mixed tracks.

The settings do look like they should work as expected.

Have you actually re-ingested your exported file and checked yourself there is a problem?

Or use media info and see if you are getting 8 tracks.

I’m on Avid but use PP sometimes.

The critical factor is how you set up your Output Assignments. Have you done this right?

Hi Guys,

Thanks for all your responses. The film has been mixed already and I had the stems. It is for quality control, so they are checking all the audio channels and video elements for anything a distributor or network might reject.

I did find the answer though, had to patch each track in the timeline 1-2,3-4,5-6, and 7-8, in the mixer then export as mono tracks in the exporter 1-1, 2-2 etc, as discrete.

When I exported a test and re-imported, I could see all the tracks where perserved.

With respect, this is not “the answer” and in doing it this way you are messing with your output levels.

This is quite significant.

In this example, channels 1/6 are showing your method (note the discrepancy with the Lfe track) and 7-12 are showing the correct method.

You are losing 3dB of gain with your method and unbalancing the Lfe because it is not being attenuated.

Hi Simon,

That’s not good, lol. How do you see it working?

The reason I don’t make a 5.1 and stereo mix file, (as your first post suggests) is they have asked for:

‘The audio should be exported as 24-bit, and each channel should be printed as its own Mono track, rather than delivered as a 6-channel and a 2-channel track. Be sure to export the channels direct so they are not mixed together.’

Do you have a suggestion as to the correct export, without getting the -3db gain and exporting mono tracks?

Or do I have to export as 5.1 and stereo to make it work? If you explain it to me, I can try and explain it to them and maybe get my film in that way.

Thanks

Hi Shane,

I have Resolve as well. But struck out there too. Do you have a workflow to export all 8 tracks as mono seperate discrete channels?

Thanks!

The first step I would suggest it to Modify the mono clips in the Browser – right-click, Choose Modify/Audio Channels.

Set the Clip Channel Format to 5.1. And choose the appropriate channel for the track. Here I’m choosing C because I’m modifying the Centre track.

Premiere now knows how to route the clip in a multichannel sequence if you lay them in as 5.1 tracks rather than mono tracks.

Because the default output assignment is 1-6 you’re now in good shape for the 5.1 mix.

You then simply need to add a stereo track to the sequence for your stereo mix and make sure that its output assignment is 7-8.

(Note that the whole process is a lot easier if you ask your dubbing mixer to make you an interleaved 5.1 mix because it saves you having to set the channel format and you can lay in the entire mix in one go.)
