How to add a RaceChrono overlay
Four steps from raw footage to a finished overlay you key into any editor.
Export the session as CSV
In RaceChrono, export your session data to CSV.
Import and auto-map
Drop the CSV into Overspeed. Lap, speed, and GPS map automatically; remap any extra channel by hand.
Build your overlay
Add a timing tower, delta, track map, and speed gauges, then style them to your team or channel.
Sync and export
Load your footage as a reference, sync the data, and export an overlay layer for any editor.
Export the overlay. Finish anywhere.
Overspeed renders your gauges on a chroma-key background. Key it out in one step in CapCut, Premiere, DaVinci Resolve, or Final Cut, and the overlay sits right on your video.
Frequently asked questions
Why use Overspeed instead of the overlay RaceChrono generates?
RaceChrono renders one fixed overlay with limited styling. Overspeed is a full editor: pick from a wide widget library, style everything, combine multiple files, and save a reusable template.
Which RaceChrono data maps automatically?
Lap, speed, and GPS are detected on import. Add more files (such as OBD data) to the same project and map their channels too.
Can I build a custom gauge beyond the widget library?
Yes. Describe what you want, like a sector-delta tower, and the AI Studio builds a fully styled widget. Refine it in plain language and save it as a reusable template.
Make your footage look broadcast-grade
Pick a template or build your own look, drop in your data, and export an overlay ready for your next edit.
