Synch Problem - Canon 7D, Zoom H1 and Final Cut Pro 7

Hello,

I'm about to pull out my hair here. Been on many forums and sites with noluck on fixing this annoying issue. Yesterday I shot an interview on my Canon7D with my new Zoom H1 recorder. The recorder has been set to MP3 output at 128kbps. The Canon is set to 30fps.

I've set the Easy Setup option on FCP 7 to 23.98 and 29.97 (onseparate trouble shooting occasions before coming to this forum forassistance). On both occasions, the video starts playing the audio in synch butby about 1:26, the audio and video start to fall out of synch. The interviewget's pretty bad at about the 3 minute mark and completely ridiculous by theend.

Has anyone here ever dealt with this issue? I know I'm doing something verywrong....just need some advice on how to fix it.

Thanks for reading and hope there's some assistance out there.

Final Cut Pro 7, Mac OS X (10.6.4)

I'm certainly no authority on this, but I have had good results syncing the Zoom with Canon DSLR footage…meaning no audio drift. And usually I'm shooting 24 fps with the Canon. I start out by converting WAV to AIFF.

As you know, if you bring a 24 fps clip into a 30 TL, it will ask you pick one or the other. Once that decision is made, you shouldn't have any problems in theory. How you get your audio synced is another story; often I can get it right quickly by waveform inspection; alternatively, Plural Eyes is an amazing stress-reducing tool.

Good uck.

Hi Russ,

Thanks for replying. Audio drift is exactly what Im experiencing. Maybe I should shoot at 24fps from now on and convert my wav to aiff before dragging it into the timeline....

as for the picking one or the other, I'm hoping you mean when FCP asks you to choose the setting created for the job or if you want to keep it the same as what you shot.

I used both a waveform inspection method with the slate that I use as well as plural eyes. I've tried about 5 different combinations and settings and nothing seems to prevent the audio drifting.

Dont know what else to do really except try your suggestion to change the WAV to an AIFF.

Here goes nothing...

(thanks again)

Well…not really recommending 24P over 30p; but yes on converting to AIFF. Are you using Log & Transfer with the EOS plug-in? Also makes life a lot easier and preserves TC when transcoding to PreRes.
