Interesting about the 7D. We had ours set to 48khz and I noticed the same issues as the 5D — audio was generally 2 frames off.
I appreciate your deductions and had a similar thought about things landing between frames. But having just spent a few hours syncing almost a hundred clips, my experience is that more often than not, the audio reference comes a solid two frames before the visual. But I agree, a lot are just one frame off. Not that most people are going to notice one frame out of sync in either direction, but being a perfectionist, I’m not comfortable making a blanket rule of one frame (or two frames for that matter) shift on all clips to solve the issue. But maybe the next hundred of these I have to do will push me over the edge and I’ll go with it! Very annoying little issue though.
I wonder if shutter speed (I’m shooting at 1/50th) changes would help or at least be worth testing. If nothing else, a faster shutter speed would give a less blurred visual reference of the sticks… and that might give us a clearer answer on whether there is a one or two frame rule we can utilize…. assuming that the added variable of shutter speed doesn’t effect something else in this little mess. When I’m done with the edit job I’m on, I’ll try to do some tests and post the results.
Oh, the hoops these DSLRs make us jump through…

Just wondering if anyone ever figured out anything further on this. I just got done syncing a three-camera (two 5Ds and a 7D) shoot. And almost EVERY clip from each camera (across four days of shooting) had the same issue…the in-camera audio preceded the visual reference by two frames…a couple seemed like they were off by one-and-a-half.
Ultimately, not a huge problem, since I find it just as fast to sync manually in FCP, rather than using PluralEyes. But yeah… this certainly shouldn’t be happening. Does anyone have any answers? Any info would be much appreciated.
(FYI… I shot 1080 24P, Technicolor Cinestyle, conversion to ProRes 422 via EOS FCP plugin and log and transfer.)
