Cycling Video Overlay
Put speed, power, and elevation on a short ride clip, in the browser. Start from the sample, or bring your own video and a FIT or GPX file. The footage stays on this computer.

Built for local, private telemetry overlays
Most online editors upload ride clips to a remote server before burning in gauges — slow for 4K and risky for unpublished routes. This cycling video overlay runs decode, FIT sync, HUD preview, and export on your machine. Video and telemetry never leave your device; you control timing, gauge layout, and export quality.
Fully local
Parsing, preview, and export run in WebAssembly and WebCodecs inside your browser tab. Video and FIT never touch our servers — ideal for unreleased routes, club training loops, or any footage you would not upload to a third party.
4K / H.265
Hardware-accelerated decode and encode handle common 4K HEVC recordings from action cameras and phones. When HEVC export is unavailable, the tool falls back to H.264 automatically and notes the change in the UI.
FIT gauge HUD
Burn in speed, power, heart rate, cadence, elevation, distance, and a live route trace from Garmin FIT or standard GPX. The Cycling Basic layout keeps numbers readable on fast-moving POV footage without covering the whole frame.
Streaming export
Large projects stream frames to disk through the File System Access API instead of holding tens of gigabytes in RAM. Designed around ~17 GB source files so you can finish a long ride video on a typical laptop.
Use cases
Where riders add metrics to footage
Viewers understand effort better when numbers change with the terrain. A telemetry overlay turns plain POV video into explainable storytelling — climb power, sprint speed, heart-rate drift, and route context on screen at the moment they happen. The examples below are how road, gravel, and indoor riders use this browser-based overlay today.
Road ride sharing
Layer head-unit data into handlebar or chest-cam footage so followers see wattage on climbs and speed into descents. Works well for race recap vlogs and training diaries where context matters as much as the view.
MTB / gravel
Elevation profile and route trace help explain why a segment felt hard — useful for gravel adventure films and technical trail breakdowns where the camera angle alone does not show gradient or line choice.
Indoor training
Overlay power zones and heart-rate targets on trainer sessions or screen captures from Zwift and similar apps. Makes interval structure obvious when you post highlights to social or a coaching review.
How it works
How the cycling video overlay works
No desktop NLE or cloud account required. Import a 1–3 minute ride clip and a FIT or GPX file, check the sync, preview the gauges, then export an MP4 you can post tonight.
- 01
Import
Choose one or more video clips plus a matching FIT or GPX file. Clips stay referenced locally; Chrome and Edge can remember file handles after refresh.
- 02
Sync
Nudge gauge time with the offset slider when the camera clock and GPS track disagree. Suggested offsets appear when clip capture timestamps are available.
- 03
Preview
Scrub the timeline to verify the Cycling Basic HUD — speed, power, heart rate, and map trace — before committing to a long export.
- 04
Export
Pick quality and codec preference (HEVC when supported). The encoder streams output to your chosen folder; download again from the UI if needed.
