G-Metrix doesn't stay synced with GOPRO Session videos

I'm having a problem whereby the G-Metrix data does not remain synced with videos imported from a GoPro Session. I can set the start point of the clip correctly, but by the time the 12 minute video finishes the GPS/G-Metrix is about 30 seconds behind - i.e. the G-Metrix data appears at 12:20 into the video when it should appear at 12:00, so the video is running "faster" than the GPS/G-Metrix data - if that makes sense.

When I check the video file in Windows Explorer it says 1920x1080, 25,000kbps, 29 frames / second. Could it be that the GoPro isn't storing the files at 30fps and using 29fps instead?

Anyone else had this problem?

The software was made to work with Garmin cameras, not gopro's, I think your solution is pretty obvious.
Good luck

Software is made to process MP4 files with G-Metrix data - no matter whose hardware created the MP4 files or G-Metrix data. Now, I suspect, in creating the MP4 files, GoPro and Garmin may have different frame rates that may not sync up with the frame rate that the G-Metrix data is captured.
