Sorry for all the lack of info. Brain was fried after a long day and frustration.
Yes Premiere Pro CC latest version. I’m trying to sync with audio, as the time code is for some reason inconsistent across the clips even though time code was sent on set (some clips match, most do not). Synchronize with audio worked fine on the first few clips, synching to audio on track 2 (track one of the camera audio is blank, track two is camera audio, then I have 5-channel audio 1 I’m attempting to sync). Then I randomly started getting that error I posted. I resorted to manually syncing the audio, which takes forever. I managed to find some success late in the night using a similar audio sync, but changing the drop-down from “track 2” to “mix down”. For some reason, it was able to sync with no issues there for the last 10 or so clips, as I had already powered through the rest. Can’t say if that is a real fix of not, as my original workflow worked for a few clips at the outset as well…
Trashing prefs and and media cache had no effect, but everything is at least in order now…
I’m curious why you think normalizing would help. And would you think normalizing both clips would be the right workflow? Theoretically, these clips should just sync without issues, as the audio is good and clean, all has been marked with a clear clap stick. But se la vie…
