Are files uploaded to a server?

No. Parsing, preview, and export all run locally in your browser. We have no backend that receives your video.

Which browser should I use?

Chrome or Safari desktop is recommended. Firefox / Edge have weaker HEVC support and may not handle H.265 footage.

How large can videos be?

Designed for ~17 GB 4K files. Use a browser with File System Access for the best large-file export experience.

What if HEVC encoding is unavailable?

Export automatically falls back to H.264 and the UI will note that file size may increase.

Will export quality drop?

We try to match source clarity and file size. Overlaying gauges requires re-encoding in the browser; some high bit-depth camera footage may export to a more common standard profile — usually fine for sharing, but not bit-identical to the original.

Which file formats does Ride Data Overlay support?

Video: MP4 and MOV. Telemetry: Garmin FIT and standard GPX. Multi-clip timelines are supported; sort and reorder clips before export.

How is this different from Strava or Garmin overlays?

Platform overlays are tied to their upload pipeline. This cycling video overlay works on your raw POV files locally, supports custom sync, multi-clip edits, and export you own — no need to publish the activity first.

Do I need a subscription to try it?

You can import, sync, and preview on the free tier. Pro unlocks higher export quality, map-intro flyover, and other advanced options shown in Pricing.

Can I use it for e-bike or indoor-only rides?

Yes. Any FIT or GPX with the metrics you care about can be synced to matching footage — road, gravel, trainer, or mixed indoor/outdoor projects.

Cycling Video Overlay

Ride Data Overlay

Put speed, power, heart rate, cadence, and elevation from FIT or GPX directly onto POV ride footage — processed entirely in your browser. This cycling video overlay handles 4K and H.265 files up to tens of gigabytes without uploading a single byte.

Features

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Most online editors upload ride clips to a remote server before burning in gauges — slow for 4K and risky for unpublished routes.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 ride video and telemetry, adjust sync if camera and GPS clocks disagree, preview the HUD, then export a share-ready MP4. The same four steps work for a short commute clip or a multi-hour epic.

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.

Tool

Local workbench

The interactive workbench below is the product — import footage, align telemetry, and export without leaving this page. All processing happens in your browser session; we do not operate a backend that receives your media.

Video and FIT / GPX are processed on your device only — never uploaded.

FAQ

Frequently asked questions

Common questions about privacy, browsers, file size, and export quality. If you need help, use the Support link in the footer.

A telemetry overlay adds FIT or GPX data — speed, power, heart rate, cadence, elevation, and route — on top of your ride footage. Ride Data Overlay does this entirely in your browser; files are not uploaded.
