Import GoPro video with GPS telemetry

A GoPro that records GPS gives you two things at once: full lap analysis from the telemetry, and your footage with the data drawn over it.

Before you film

• Use a GoPro model that records GPS telemetry, and turn GPS on in the camera's settings before the session. Note: HERO 12 does not have a GPS sensor and can't be used for telemetry import.
• Give the camera a clear view of the sky and let it acquire a fix before you head out.

Steps

1. Get the video file onto your phone (the GoPro app, AirDrop, a cable, or cloud storage all work). Use the original file from the camera — an edited or exported clip can lose the telemetry track.
2. In LapperSnapper, open the Import tab and tap Choose a file.
3. Pick the .mp4 (or .mov) file. The app checks it for GoPro telemetry.
4. When it finds some, choose New session from GoPro data to build a session from the video's own GPS and sensors. (Attach to a session instead adds the footage to a session you recorded with another device, using that session's telemetry.)
5. A long clip takes a moment to copy — a progress bar shows, and you can cancel. The session then opens with laps, the track map, sectors, and coaching — same as any other source — and a Track conditions sheet asks how the track was (see Tag the track state after an import).

Watching the video

Open the session's Video tab to play your footage with speed, lap time, delta, and a live track map overlaid. See Watch your lap with a telemetry overlay.

If the app finds no GoPro data

You'll see No GoPro data found, and the app offers to attach the picture to a session you choose instead. That means GPS was off, the camera has no GPS, or the file was re-exported. If a new session imports but shows no laps, the camera may not have had a good fix — check its GPS setting, and see No laps were detected in my session.

Video import needs the iPhone or Android app — the web app can't import video.
