Add a speed, GPS and map overlay to your dashcam video
dashcamigo can burn your speed, GPS coordinates and a moving mini-map straight onto the exported video — clean readouts baked into the picture, not a separate app. It runs in your browser, nothing is uploaded, and it works with the GPS your dashcam already recorded.
Open your recordingsSpeed and location, baked into the picture
A dashcam clip on its own doesn't show how fast you were going or where you were. dashcamigo reads the GPS your camera saved and draws it onto the exported video: a speed readout, your coordinates, and a small map that moves with the route. The data is part of the picture, so it stays visible wherever the file is played — no special player needed.
Everything happens in your browser. Your recordings are read locally and the overlay is rendered on your device; the finished video is saved straight to your computer.
What you can overlay
- Speed — A clean speed readout in km/h or mph, drawn in the corner you choose.
- Coordinates — Your GPS latitude and longitude, updated as the route moves.
- Moving map — A small map that follows the route — drag it where you want, set how much it zooms.
- Watermark — An optional small mark in a corner of the frame.
How to add the overlay
- Drop the SD-card folder onto dashcamigo.app and open the trip.
- Open export and turn on the overlays you want — speed, coordinates, the moving map.
- Drag each one where it should sit and pick the range to save.
- Save — the overlay is rendered onto the video and written straight to your computer.
Free, in the browser, for dashcam footage
Burning speed and a map onto video is usually the job of paid desktop tools built for action cameras. dashcamigo does the dashcam version for free, in a browser tab: it reads the GPS from 70mai, BlackVue, Viofo, Garmin, Vantrue and more, and draws speed, coordinates and a moving map onto the export — no install, no account, nothing uploaded.
The overlay needs GPS in your footage — if a recording has no GPS track, there's nothing to draw. Beyond speed, coordinates and the moving map, it can also show the time, your heading, distance travelled and a G-force read — all worked out from the same GPS, not a separate sensor. Rendering re-encodes the video, so a long range takes a little time; Chrome, Edge or another Chromium browser on a computer is smoothest.
FAQ
How do I add a speed overlay to a dashcam video?
Open the trip, go to export, and turn on the speed overlay. dashcamigo reads the GPS your camera recorded and burns a speed readout (km/h or mph) onto the exported video. You can place it in any corner.
Can I show GPS coordinates and a map on the video?
Yes. Alongside speed you can overlay your latitude and longitude and a small moving map that follows the route. Drag each one where you want it and set how much the map zooms.
Does it need GPS in the recording?
Yes. The overlay is drawn from the GPS your dashcam saved. If a clip has no GPS track, there's nothing to overlay — the video still exports, just without speed, coordinates or the map.
Is my video uploaded?
No. There's no server. The overlay is rendered locally in your browser and the finished video is saved straight to your computer.
Can it also show time, heading or G-force?
Yes. Alongside speed, coordinates and the map you can add the time, a compass heading, distance travelled and a G-force readout. The G-force is worked out from your GPS — how your speed and direction change — not from a separate sensor, so it needs GPS in the footage like the rest.
