We are editing in Premiere some footage that was shot with a Sony FX3. In Premiere the audio has a 2 to 3 frames off-synch wich does not appear in Davinci Resolve neither in FCPX. We thaught it was the cam, turns out it's Premiere. Even when audio scrubbing is on we hear it off-synch. We tried in 2 different computers and it's only in Premiere.

Jean-Philippe, we have just discovered the same issue utilizing FX3 footage and Premiere since recently updating to the most recent firmware on FX3. I found a post on Reddit that mentions a similar issue. Checked both my phantom powered mic and the internal mic recording and they both appear off the 2-3 frames. I did not think about trying it in other editing software, so based on your finiding it would make more sense if it would be a Premiere issue. Did find a mention on Sony's site about audio out timing. Wondering if this could also be related to live vs lip sync on the FX3. I will do a test on this as well, but wondering if you have since found any solutions or additional findings on your end.  Thanks so much!
