Folks I had to use PluralEyes to sync a lot of multicam clips in order to correct sync drift. I didn't realize that the corrected audio boiled all of the channels in the polyphonic original into one mixed audio file. PluralEyes is a tool I rarely use. I don't recall any preference for this, but can PluralEyes maintain the channel configuration after syncing and exporting the audio file? Using FCP X by the way which indicates that there's no longer the original channel configuration nor the iXML info.
