Syncing GH2 video and Zoom H2n audio

[jeffdeponte]

Ho folks,

I have now shot a couple of interviews using this setup. Frame rate is 1080 24p. I can easily sync the audio and video, but after a few minutes, they drift apart. By 30 minutes, they are waaay off. Am I missing something here? Is there a protocol I need to follow?

Thanks in advance...

Jeff

Are you recording audio at 44.1khz or 48khz? Try making sure the sample rate matches your project settings.

Thanks for that tip. They do NOT match. My bad! Must spend more time testing, but I think you've answered my question.

Again, thanks!

Jeff

Sampling rates must match as another member has mentioned.

Is running a line out from the H2n into the GH2 an option for you?

I use a Sescom Line to Mic adapter, with a 25ft extension with my H2n, For most situations it works pretty good.
Although the wave file from the H2n is better, but with a little testing you can put that available stereo track in the AVCHD to good use.

With out careful attention to the subtle differences, and comparing wave forms on a frame level, it's hard to tell the 2 audio recordings apart.

The recorded H2n track on the AVCHD sounds pretty good.

I mount the H2n to a mic stand with boom arm, as you would do with a Boom Mic.

If you have an available monopod and an extra hand, you can do a decent run and gun using the H2n on a monopod to get it up and out of view.

Thanks Travis, I do have the hardware that you mentioned, and yes, I really should record the H2n output into thte GH2. But, no, I do not have an extra hand! LOL!
