Clips going out of sysnc

Currently working on a four camera MultiCam edit.

FCP x 10.1 sync's all the clips up at the start of the time line fine but as we get further into the project everything is moving out of sync.

Shot on two JVC HM700 - set to 1280 x 720 24fps. One camera as fixed wide shot of the stage, one "manned" which I am also using as the primary audio source.

Go Pro - set to 1280 x 720 24fps and a small HD camcorder 1280 x 720 59.9p

Any suggestions for a simple fix to keep the JVC's & GoPro in sync throughout the whole project (just over an hour long play)

Thanks

Final Cut Pro X, OS X Mavericks (10.9.2), IMac 27"

Is all the audio 48 Khz?

How long does it play before it's noticeable?

Hi Russ

Sorry for the late reply, Easter !

Audio & Video rates all match.

I noticed that the Go Pro dropped a lot of frames that did not help, so as a work around I have chopped it's track up into 10 min sections and then fine tuned the clip so that lip sync looked Ok.

The JVC remaine in sync for most of the video.

Many thanks

Alli
