What telemetry format does iRacing use?

iRacing uses .ibt (iRacing Binary Telemetry) files. StintBox reads these natively.

Can I overlay live during a race?

StintBox is designed for post-session overlay. Record your replay, then add the overlay in StintBox for the highest quality.

Does it work with other sims?

Assetto Corsa and ACC are also supported via shared memory telemetry. More sim platforms are planned.

How it works

Record your session

Drive your iRacing session as normal. Use screen capture (OBS, ShadowPlay) to record the replay.

Export telemetry

iRacing saves telemetry (.ibt files) automatically. Or use StintBox live capture during the replay.

Import into StintBox

Drag your replay video and telemetry file into StintBox. Data aligns to the video timeline.

Overlay and publish

Add lap delta, tire temp heatmap, inputs trace, and fuel gauge. Upload directly to YouTube.
