Your GoPro is a data logger
By LapperSnapper ·
If a GoPro was on the kart, the data already exists. GPS-enabled models write position and speed into every video file — the footage you shot for the group chat is also a session.
Which GoPros
Compatibility depends on the video containing GPS metadata, not just the model name. GoPro documents embedded GPS telemetry for HERO5 and HERO11, and a GPS preference on HERO9 and HERO10. HERO12's official feature list does not include GPS. Check for the GPS setting and record a short test clip before relying on a camera for a session.
Before the session
Turn GPS on in the camera's preferences, and give the camera a clear view of the sky for a minute before you roll out — a settled GPS lock at the start beats one acquired mid-lap. Then record like you always do.
After the session
Load the .mp4 (or .mov) into LapperSnapper. The telemetry is read straight out of the video file — no camera connection, no export step, the file is the transfer. Laps, sectors, and corners are detected from the GPS, the same as any logger.
The part only video can do
Because the data and the footage are the same file, playback comes with the telemetry overlaid — speed, delta, the map — and any lap can be exported as a clip with the overlay burned in and the audio kept. Proof you can share.
If no data shows up
GPS may have been off, the camera may not support it, or the recording may not contain a usable satellite lock. The video still plays — there is simply no GPS track to time. Check the camera setting and make a short outdoor test recording before the next session.
Verification. Embedded telemetry checked against GoPro's official HERO5 metadata explanation, HERO11 guide and camera manuals; LapperSnapper video import and overlay behavior checked against the current app implementation.
