Data synchro drift
Hi,
I am using Race render to overlay my rally videos (3x GoPro Hero2 cams) and my data acquired from a Race Technology DL1 logger.
The Cameras are Running at 25Hz and the Logger at 100hz.
I can synchronize the data at the beginning of the video, but at the end of the video, the data have drifted. The longer the video, the more the drift. I know the Play speed trim, but it doesn't seem logical, because of the frequency ratio between video and data.
Any hints?
Thanks

I have this same issue with a GoPro Hero4 Silver and Aim Solo DL.
It seems like a frequency issue but can't seem to resolve it.
Could it be that GoPro uses a Variable FrameRate causing the drift issue with the logging data?
