GH2 Audio setup with GH2, monitoring the audio during a shoot

[TheDingo]

sounds logical, but just in some scenarios... not always. not for doco works, for example

You can still slate your work and keep track of the timing for each take, you just don't turn the camera or recorder off so that synching will have to be done only once, up to what will fit on to a memory card or when you are finished filming in a specific area. I've done this with up to 3 hours of footage as one video clip, without any problems.

Good old hand clap for syncing... If you can't get one in at the head of the take... then do it as a tail slate... clap at the end...

The spike in the timeline is easy to match... the only issue I have is sometimes it's a 1/2 frame out and video editing software won't allow you to slip less than a frame...

We never really had audio on 16mm only some mag-striped reversal stock for shooting with the Arri CP... it was all double headed...

...But you can easily adjust the timing of the audio track to be an exact match of your video. I went through a half dozen audio editors trying to find one that was accurate enough to re-time 3 hours of audio to be frame accurate with the video I shot, and surprising the only one up to the task was the cheapie $19 GoldWave editor.

GoldWave Audio Editor : $19

The function you use in GoldWave is called "TimeWarp" which allows you to re-time an audio track with a real accuracy of 0.0001 seconds.

1/2 frame out is pretty difficult to see and hear (ie. notice during playback).

Its 1/100 of a second.

I think it goes without saying that if you can find it you can fix it, otherwise it's not a problem. ( nobody will ever notice if you don't )
