I built this because syncing power, heart rate, and speed data to GoPro footage was a pain.

Existing options were either manual work in After Effects or expensive plugins.

  Telemetry Studio lets you drop in a video and a FIT/GPX file, line them up, and export with data overlays - power zones, HR, speed, GPS map, elevation, and more. It also pulls your Strava segments and shows live PR comparisons during the ride.

Built in Rust with iced, wgpu, and FFmpeg. Native macOS and Windows app.
