I've only ever used TrackAddict with my smartphone video. It's been over a year since I did that. As I recall (looking back at the files I have in ReceRender project) the video and data files for each lap are paired-off with similar file names so you can easily match them up for use in RaceRender. I now have a GoPro. I have it set so TA triggers the GoPro via wifi to start recording. Will I get similar individual lap pairing of video and data file names or is the GoPro going to give me one big multi-lap file? I sure hope the individual lap files are paired up.
