Syncing audio problem

Well i've probably watched half a dozen tutorials on youtube, and watched the Steve Martin tutorial i bought several times, and i still can't sync my clips from my Zoom H4. The fact is, the "good" audio from the zoom is not in sync with the bad audio from my 5d mkii. So having ended up with a synchronised clip and done everything the tutorials say, the clips are still not in sync. What could i be doing wrong?

Did you record at 48kHz on both devices? If you're doing the syncing properly, the clips should stay relatively in sync for at least 45 seconds or so, even if you had different sample rates. How big is the difference? Is it a simple offset (ie. two seconds off at 10 minutes, two seconds off at 20 minutes) or a drift (ie. two seconds off at 10 minutes, five seconds off at 20 minutes)?

Hi Derek, thanks for the swift reply.

OK, think i've seen the problem. the new synchronised clip's specs are 720p and 23.98 fps when the original is 1920 by 1080 25 fps. So i guess i need to get this clip consistent with the others. What's the best way to do this, and why is this happening?

So it seems my project properties are 720p 60p. I was under the impression that it would automatically set the project to 1080 25 fps when i started importing my footage from the 5D?

What's the best way forwards now? I've not started cutting so could easily go back to square one and reimport from the media cards, but i'm sure there is a much simpler way around this.

OK. So i have changed the project properties which were wrong and now everything is 1080p. I have re-synchronised the two clips i wish to use and the synchronised clip is now 1080p too. Unfortunately it is still 23.98 rather than 25fps, so i still have the same problem. Hmmmm....

I'm not sure what you're doing, but you can't, or rather, shouldn't change your frame rate after you shoot.

Everything is shot at 1080p 25fps on a 5d mkii. The Zoom was set at 48hz. The problem is that when i make a synchronised clip it becomes 23.98.

It turns out i had the wrong project settings, but have put them right now but the problem persists.

You're all over the place. Take a deep breath and go back to the beginning.

First of all, what are you supposed to deliver? 25fps or 23.98fps? That determines what all your settings should be.

When you say you end up with a "synchronized clip", exactly what do you mean? Are you using a nest? Subclip? Merged clip (separate video and audio, linked in a Sequence and then dragged back into a bin as a new master clip)?

And Project Properties isn't where you change the frame rates of your Sequences. That option only affects how timecode is displayed. Exactly what setting are you looking at here?

The footage is 1080p 25 fps and should stay there. I have captured my audio separately (for an interview) on the Zoom at the correct settings. I usually use FCP and plural eyes, with no problems, but decided to give the new version a go. i highlight the clip front the canon and the clip from the Zoom, ctrl click and choose synchronise clips. It creates a new clip but the new clip is 23.98 rather than 25 fps.

Perhaps i should have mentioned i'm doing this while looking after my 16 month old daughter. So yes, i'm a little stressed. In fact she's demanding a trip to the park now so i'll have to leave it there and come back later. Any help gratefully received.

This is a bug with FCP X 10.0 - when using the official method, the new compound clip that is automatically generated does not match the settings of the video clip if it is 1080p25.

After trying twice, I've synchronised by eye and ear since.

Thanks for that. So this wonderful new function that makes pluraleyes redundant is actually useless? WTF!

I have loads of stuff to sync and no claps (or anything else) to use as a reference. Anyone know if this problem has been addressed in the update?
