Ride Data Overlay guides

Cycling Video Telemetry Overlay Guide

A cycling video telemetry overlay combines time-stamped ride data from a FIT or GPX file with action-camera footage. Ride Data Overlay performs the import, synchronization, preview, and final MP4 render in a supported browser, so the source video and activity file stay on your device.

Choose the guide that matches your job

  • Use the Garmin FIT guide when you want power, heart rate, cadence, elevation, speed, distance, and route data from a bike computer.
  • Use the GPX guide when location, route, elevation, and GPS-derived speed are the main inputs.
  • Use the synchronization guide when the camera clock and bike-computer clock do not match.
  • Use the 4K/H.265 guide before working with large HEVC action-camera files.
  • Read the comparison guides when deciding between a local workflow, platform overlays, and other telemetry tools.

What the browser workflow does

The workflow has four stages: import MP4 or MOV clips, import FIT or GPX telemetry, align the two timelines, then preview and export. Metric availability is detected from the data rather than assumed.

The final result is a video with gauges rendered into the frame. This is different from exporting a transparent overlay for compositing in another editor.

Verified capabilities and boundaries

  • FIT and GPX telemetry input; MP4 and MOV video input.
  • Speed, power, heart rate, cadence, elevation, distance, route, and elapsed-time displays when source data is available.
  • Multiple source clips can be ordered on one ride timeline.
  • Free accounts can export up to three minutes per file with a fixed watermark.
  • A separate FIT or GPX file is required; Ride Data Overlay does not extract embedded GoPro, DJI, or Insta360 camera telemetry.
  • Browser codec and file-system support varies, so the app checks capabilities before export.

Frequently asked questions

Does Ride Data Overlay upload my video?

No. Video parsing, telemetry parsing, preview, and rendering run locally in the browser. Account, billing, and anonymous analytics data are separate from the media-processing path.

Which guide should a Garmin user start with?

Start with the Garmin FIT guide, then use the synchronization guide if the camera and bike-computer timestamps differ.
