Works with
RaceChrono video overlay
TrackHero renders RaceChrono telemetry onto your onboard video. Export your session from RaceChrono Pro as a VBox (.vbo) file, load it into TrackHero alongside the video, and export an MP4 with speed, G-force and lap-delta gauges burned in. It is free, runs in your browser, and your footage is never uploaded.
Why you need a separate tool at all
RaceChrono draws a live overlay inside its own video player, but it cannot hand you that overlay as a file. The overlay leans on an alpha channel, and ordinary video containers do not carry one, so what you see in the app cannot be exported directly. Anyone who wants a shareable video with data burned into the picture has to re-render it somewhere else.
Historically that meant DashWare, which stopped being developed years ago, or a paid desktop application. TrackHero does it in a browser tab, for free.
Exporting a .vbo from RaceChrono
Session export is a RaceChrono Pro feature. In the app:
- Open the Lap times list for the session.
- Press Options, then Export laps.
- Set Type to VBox (.vbo).
- Choose a Scope: Best lap, Selected lap only, All laps, or Traveled route.
- Press Start.
Pick All laps if you want lap deltas across the whole session. A single-lap export gives TrackHero nothing to compare against, so the delta gauge has no reference and will not display.
One detail worth knowing: if you had videos linked to the session in RaceChrono, the export writes video sync points into the comments in the .vbo header. Open the file in a text editor and you can read them. TrackHero does not depend on those, since it syncs against the video’s own audio track, but they are a useful sanity check if an alignment ever looks wrong.
What ends up on the video
Once the session and the footage are loaded and aligned, TrackHero can render:
- a circular speed gauge whose needle turns red as you approach the session’s top speed;
- a G-force plot scaled to the peak G in your own data, so it stays readable whether you are in a road car or on slicks;
- a live lap delta against your best lap in the session, green when you are up and red when you are down;
- a lap overview of your last four laps, with outlap and inlap badges and your fastest lap highlighted;
- a driver and session panel with name, photo, car, track and weather.
Every element is optional and only appears when there is data behind it.
Requirements and limits
TrackHero runs in Chrome on a desktop computer. The encoding pipeline uses browser APIs that are not yet available in Safari, Firefox or on mobile. In exchange, there is nothing to install, nothing to pay for, and your footage never leaves your machine. The only network request the app makes is an optional weather lookup, and only if you type in a track name.
