GPS Sync

Turn your ride into a map you can explore.

GPS Sync lines up your GPS track to your action‑cam footage and lets you relive the route on Apple Maps while the video plays — then bakes beautiful telemetry overlays straight into your clips. Built for riders, drivers, cyclists, pilots and hikers who record with a camera and GPS.

Built for cut and multi‑clip footage — not just one video and one track.
Other overlay apps line up a single clip to a single GPS file with one fixed time offset. The moment you've trimmed the video, or your camera split the recording into chapters, that one offset stops lining up. GPS Sync breaks the video into segments — at every cut and every clip boundary — and syncs each segment to your GPS independently, so a heavily edited, multi‑file ride stays locked from start to finish.

Or don't sync at all.
Recording on a GoPro with GPS on? GPS Sync reads the camera's embedded GPS straight from the file — including GPS9 on HERO13 and newer — and syncs it automatically. No separate track, no anchoring. With several clips, each clip uses its own GPS.

Or sync in one click.
If your track has real timestamps, Sync by Time lines it up to the video's recording time — across single clips, cuts, and multi‑clip loads with stop‑start gaps. Want it tighter? Drop or drag an anchor and your manual placement takes over.

Real sensors, not estimates.
Record with the companion Tripper iPhone app and import its .trip file: barometer‑fused elevation, true slope, directional g‑force and lean measured by the phone — plus your heart rate, if you rode with a monitor. Heart rate shows in the info bar, as a line on the profile graph, and as its own overlay gauge.

Bring any track, take any track.
Import GPX, KML, KMZ, NMEA or Tripper .trip; export back out as GPX, KML, KMZ or NMEA with your markers as waypoints. Aligned to a video, the exported track is rebased to the video timeline; on its own, it keeps the ride's original timestamps.

Find your sync point visually.
Scrub the video and watch a marker sweep along your route on Apple Maps — Standard, Hybrid or Satellite. Spot a turn in the footage, click it on the map, done. Colour‑coded, numbered anchors keep every segment clear, and two anchors cancel camera‑vs‑GPS clock drift.

Explore paths you never noticed.
Colour your track by Speed, Grade, or G‑force and study your route against the synced video. A speed / elevation / heart‑rate profile graph under the map lets you scroll‑zoom, pan and scrub the whole ride, while Follow mode keeps the map locked on you — even while you zoom. See where you carried speed, where it got steep, and where you were hard into the corners.

Overlays, exactly how you want them.
A visual editor on a 16:9 canvas: drag to place, resize, and colour each element, with snapping, guides and rulers. Speed, altitude, slope (a cyclist that pitches with the grade), compass, g‑force, lean (a cyclist that banks through corners), heart rate, coordinates, trip time, a mini‑map, and a speed/elevation graph. Save your own presets or start from a built‑in one. Metric or imperial. A parked bike reads a true 0.

Your clock, your choice.
Show the transport and trip time as video time, GPS time, or time since your in point — they differ when camera, logger and in point didn't start together.

Back it up.
Pack Project collects the project file, the original clips and the track file into one self‑contained folder that reopens anywhere — even on another Mac.

Export like a pro.
• Remapped track as GPX, KML, KMZ or NMEA — a perfect 1:1 companion to the footage.
• Video with overlays burned in at Source / 4K / 1080p in H.264, HEVC or ProRes — overlays render at full output resolution, pixel‑matched to the preview.
• Green‑screen or transparent ProRes 4444 alpha for compositing in your editor.
• In/out points export just the good part.

Hardware‑accelerated on Apple Silicon, with audio kept intact, live progress and ETA.

GPS Sync — sync it once, then go exploring.
