Hey Stan,
I’m having the same damn problem! See my posting below:
https://forums.creativecow.net/readpost/8/1120638
I’ve tried various things as you can see. No luck so far. I’m converting the camera’s audio to 48/16, the sequence is 48/16 and my external audio is 48/16. Syncing with Pluraleyes and still the audio drift. Pluraleyes admin has told me that the internal clock on the commercial voice recorder isn’t very accurate and is causing the drift. Still trying to find a solution. Any help or comments from the CC community would be greatly appreciated!
Good luck Stan..
