Turn a RaceChrono CSV into a broadcast-style overlay
RaceChrono logs a great session. Overspeed turns that CSV into the kind of timing tower, delta, and track map you see on televised racing, styled your way and reusable on every video.
RaceChrono is one of the best ways to record a session, but its built-in overlay is fixed and limited. Export the data to CSV and Overspeed becomes the editor: a broadcast-style timing tower, a live delta, a clean track map, and your own styling, saved as a template you reuse every time.
Export the session as CSV
In RaceChrono, open the session and export it to CSV. That file carries lap, speed, GPS, and any extra channels you logged, such as OBD data.
Import and map columns
Drop the CSV into Overspeed. Column detection maps lap, speed, and GPS automatically. Anything it cannot place, you remap by hand in one click.
Build the timing tower
Add the lap timer widget to get current lap, last lap, best, and a live delta to your fastest lap. Position it where a broadcast would put it and style the type and colors to your team or channel.
Add the track map and speed
The GPS trace becomes a clean track map with a moving marker, so the racing line is obvious. Add a speed gauge and a G-force readout to round out the story.
Compare stints and drivers
Add more than one CSV to the same project to compare your laps against a teammate or an earlier stint, corner by corner. This is the same workflow karting teams use for coaching.
Sync and export
Load your onboard footage as a reference, sync the data to a known moment, and export the overlay on a chroma-key background. Key it into your editor and you have a broadcast-style recap.
