Your race video already has the telemetry.

Your GoPro records GPS along with the picture. SpeedSync reads that data straight from the file, puts speed, track map and lap times on the video, and shows which corner cost you time.

You come back from the track with four GoPro files and one question: where did I lose time? SpeedSync opens the files, finds all 30 laps, measures each of the 6 corners and shows your ideal lap: 50.188. A second and six tenths faster than your best.
