Best way to replace Audio Channels in multiple sequences
I’ve been editing a project with 2-channel scratch audio for some time. We recorded 4-channel separate system sound and I would like to replace the 2-channel clips in the timeline with new 4-channel clips. I can get Pluraleyes to match the soundtracks and export the same video files with replaced 4-channel audio. However there’s no way in Premiere Pro to batch replace clips already in sequences — I can replace clips in the bin (via Modify: Audio Channels) but there’s no way to get the 4 channels into sequences unless I do every clip manually… which is impossible given how many hundreds of them there are. Any suggestions?
(Pluraleyes may have a way of doing this using its Premiere Pro connector but Pluraleyes is freezing on any export except “to audio file” or “to video file.” That’s why I’m asking in the Premiere Pro forum — I’m looking for a solution in the NLE itself).
Thanks so much for any insights!

Ho boy.
You need to sync up this nice, clean audio BEFORE you edit….not after. Now you’ve painted yourself into a corner…big time! PluralEyes won’t do this. There is an app that does fix this mis-step…but it only works for FCP and FCX:

Dude…you need to add the nice audio to your video before you begin editing. Yes, I just said that…but it bears repeating. I’m sure you’ll never make this mistake again…because how you are going to fix this will be, well, very very time consuming. What you’ll need to do is sync this audio with your originals…making new synced clips. And then…cut by cut…look at the clip you have in the timeline, note the timecode, find the sync’d clip with new audio…replace the clip in the timeline with the new one with new audio. Or just the audio.
Clip…by…clip.

Well it sounds like the OP remuxed a copy of his footage replacing 2 channel audio with 4 channel.
Now if both copies had been 2 channel audio you’d be sitting pretty. You can force relink an entire project just by renaming the folder the footage is in and use that opportunity to relink it to the new group of source clips.
Since you’ve introduced more audio tracks, you’ve caused a problem. Once a file is in the timeline, it’s semi-independent of the instance that is in the bin. What I mean by that is if you drop just video into the timeline, there is no mechanism to force Premiere to refresh it to the point where the audio appears.
For now, unfortunately, it looks like you may be stuck with match frame and replace.
Beyond that, if you’re computer savvy, there may be a way to manipulate an exported EDL to include all four tracks and then bring that into Premiere. It would take some intense text editing…. but it might be the way to go.

Thanks guys… That’s what I was afraid of, but as you say… Lesson learned!

Hi guys,
you’ve quite summed up the issue…
I had this problem and resolved by relinking to 2-channels remuxed files.
That compelled me to premix my 5 tracks of audio to a stereo, but it saved my day !
From now I’ll always sync right after ingesting the footage.On the other hand, editing with big stacks of audio tracks under each clip is also a pain…
Do you have any tip to help on that ?Thanks for the help 🙂
