    I just finished a 90-minute concert video only to realise I’d forgotten to remap the stereo source clips to mono. Now I have a stereo master track with dodgey audio on Channel One and okay audio on Channel Two. How can I use submixes to break these L & R audio tracks out so I can independently adjust levels and apply filters? Any advice gratefully appreciated. I don’t want to start again!

    Unless……. I duplicate Track 1 (stereo) to Track 2 (stereo) then use submixes to pan…

    I guess if (channel one is dodgy, and) channel 2 is OK, you might have decided just to create a mono submix and feed it using a track-level audio filter (or maybe even just use the channel pan control?) to take only (mostly) channel 2 ..?

    Haven’t tried it, so I may be off base, but would the following approach be workable:

    Unlink audio and video, copy the audio track twice to 2 new audio tracks, use Fill Left on one and Fill Right on the other track and then delete the original track or disable it. Your master track will still be stereo, but comprises both the left and right channel, due to the filters. Now you can apply filters to each track to improve the sound.

    Apparently this is changed in V2 with the naudio mapping feature, but in 1.5 the fill left and fill right is the way to go…

    If you have Audition this might be a good time to put it to use. There are a couple of approaches you could employ. One method, if there are not a huge number of clips, is to select each clip on the timeline and edit them in Audition. This will replace the existing audio with a new wav file that will be added to the project and linked to the video clip.

    The second method would be to export the timeline’s audio as a stereo file and mix it down using the channel mixer tools of Audition. Import the mixdown into PPro and lay it on it’s own track. Mute the original audio tracks leaving them in place should you have to make changes in the future.

    I concur with Alex.

    Alternative if you were going to Protools for final mix etc is export an OMF . This automatically separates the tracks. – Of course you would need the Auto Duck OMF exporter plug in which by the way is brilliant (if not a little pricy.) Mine has paid for it self a few times over now.

    Thanks everyone. In the end I exported the main setero track as a single stereo export, re-imported then re-mapped as 2x mono. Not ideal but a workaround. You lose your clip separation on the audio but hopefully the client won’t chnage her mind. Ha!

    There is another way of doing it (for the future):

    1. Take your audio track and duplicate it.
    2. Place one copy on Audio 1 and the other copy on Audio
    3. Apply the Fill Left filter on Audio 1 [Effects > Audio Effects > Stereo]
    4. Apply the Fill Right filter on Audio 2. [Effects > Audio Effects > Stereo]
    5. Now, what you have effectively “separated” the left channel and the right channel.
    6. Adjust accordingly 🙂

    wasn’t paying attention to the “after finished” part….
