Synchronise
Have been trying out the Synchronise function and getting very frustrating results. If I edit the video into a timeline and then attach the audio at the clap then everything is gravy and stays in sync. If I synchronise the two shots it does not get it right (which is annoying but fixable), but the audio also slips slowly out of sync as if there is a sample rate issue (but both are 48). To fix, I have to double click to load the shot in the timeline and then slow down the audio to 96%.
Video is 1080p25 from a Canon 7D, audio is a WAV 48khz from a Zoom.

Might be better to post this on the FCP X techniques forum. You’ll probably get more action there.

Open the activity monitor (or whatever it’s called) command-9.
Make sure it’s done analyzing. I saw this once when I started editing with the clip right away. Once I waited, it was fine.

Does it need to to the analysis of the audio in order for the sync to work? I though the analysis was just for denoising etc.

I have only had great results so far with the 7D and H4N and the new sync tool.
But, because the audiomof the 7D is a few frames off, so is the synced H4N audio.
And the 7D doesn’t follow exactly filmstandards framerates. It drifts a little, so sometimes in long takes you need to adjust the snyced clip. But that is the same even if you manually sync them on FCP7 in my experience.
