do stereo clips in multicam sequences cause problems during turnover?

​@PaulMurphy I’m working on a documentary where they shot on multiple iPhones and insta360 cameras that I have to sync and put in multicam sequences. Since there’s no timecode and it’s thousands of clips, we’re using Syncalia 3 to sync the clips. We’re using LucidLink, so we’re making proxies for all the footage so the multicam sequences will play back over the internet. The iPhones and insta360 cameras recorded audio as stereo. 

To use Syncalia to sync, we have to export an XML to Syncalia, let it sync, then export an XML to  import into Premiere. The last step results in a “sync map” sequence, which we’re turning into a multicam sequence, that uses a duplicate set of source clips. 

In order to attach proxies to the duplicate source clips, we need the duplicate source clips to be stereo. Unfortunately, mapping the duplicate clips to mono won’t help because they’re stereo in the sync map that we’re turning into a multicam sequence. 

Will having a mixture of stereo and mono clips in a multicam sequence cause problems, especially when turning over to a post sound mixer?
