I have converted my video files from .MTS to ProRes (Proxy). When I play them back in QuickTime everything is fine. When I import them into Final Cut pro, they start getting out of sync with the audio at the end of the clip (they're about 20 minuts long).
I'm at a loss why this is happening. There is no problem in QuickTime. Why would there be in Final Cut Pro. Final Cut tells me that all files are 48,0KHz, 16-bit integer.
This problem solved itself when I upgraded to the final OS 10.9 (Mavericks) and installed the latest iMovie. Now I can import MP4 files from the GoPro right into iMovie.
I create a new Aperture production library for each new project. I don't want to mess up the originals. I import all necessary videos and pictures to the new production Aperture library and then syncronise that production library through iTunes: clean and simple! Sometimes the syncronisation has some problems but then you just need to close your Aperture and close your iTunes. The syncronisation does not look to work most reliably that is a bit painful. To circumvent the syncronisation problem: the Time Capsule may be a solution -- as suggested here.
Community wiki answer where I am documenting solutions. Bruno here provided the solution fastest for finding the files in Quora but I am not able to get them into iTunes. I don't know yet how to syncronize things over OSX and iPhone now easiest, testing.
0. Create iMovie projects in OS X and iOS that you synchronise -question
I. Finding video files (found in MTS format)
Go to the AVCHD file (that is actually a folder)
- click "Show Package Content"
click "Show Package Content" again with something called B
now the videos are *MTS files. Enjoy!
II. How to get MTS files to iPhone?
MTS files do not work directly in iPhone. So you cannot transfer them just like that from the STREAM/*.MTS to DropBox and open in iPhone.
III. How can I get the videos from the camera to iTunes and sync to iPhone? Drag and dropping does not work from the video view to iTunes.
IV. How to get the videos easiest to iPhone from the Sony camera?
I don't know the answer yet.
V. How to get the videos easiest to OSX from the Sony camera and iPhone?
I don't know the answer yet.

What do the original files show up as in a media app such as VLC? Does this info match what Final Cut says about the ProRes copy? The video frame rate, audio sample rate, and other information should match exactly. Then, your FCP sequence settings should be identical.
Another way to address small sync drifts is to razor-cut the audio and manually re-establish sync a few times on the project.
