GoPro telemetry overlay
for speed & heart rate

Put speed and heart rate on your GoPro video with GaugeReel, the Windows and macOS desktop app from gaugereel.net. Read GPS from supported GoPro recordings or add a recorded FIT or GPX activity. Heart rate needs an activity that recorded it. Choose your gauges and export an overlay for your video editor.

How it works

Add numbers to your GoPro video

Import the original MP4 to read supported GPMF data, or add a recorded FIT or GPX activity. Check the data against a visible stop or start and adjust the time offset until it matches the action. Then design and export your gauges.

Reads GoPro GPMF when present in the original MP4. GPS and other streams depend on the model and recording; HERO12 Black has no GPS receiver. Pair a supported, recorded FIT or GPX activity when your footage lacks GPS data. Reframe 360 footage first, then check the data alignment against your clip.

01

Import

Drop in an MP4 and/or a GPS track. GPMF is auto-scanned from the video; FIT and GPX load as external files. Attach several sources to one project.

  • MP4 preview source
  • GPX · FIT · GPMF
  • Multi-source projects
  • Video-less mode
02

Sync

Find a visible start, stop or turn in your clip and adjust the data offset until the gauges match. Check another point later; use stretch if timing drifts. Each source has its own alignment.

  • Match a visible event
  • Offset & stretch
  • Sync-to anchors
  • Data-speed modes
03

Design

Add speed, heart rate or other gauges your recording supports. Start with Free styles, then place and resize the numbers over your clip.

  • Choose recorded readings
  • Free styles available
  • Reusable profiles
  • Grid & safe-areas
04

Export the layer

Free exports transparent PNG sequences or chroma-key MP4, up to 1920 pixels wide, 1080 high and 30 fps. Basic adds transparent ProRes 4444 MOV and VP9 WebM, or burns the gauges straight into your video as a finished MP4 / ProRes MOV.

  • PNG or chroma MP4 on Free
  • No watermark or time limit
  • Alpha video or burn-in on Basic+
  • Choose a short test first
05

Finish your video

Place the overlay on a track above your footage in a compatible video editor. Remove the colored background for chroma MP4, align the layer, then export the finished video.

  • Overlay above the footage
  • Chroma key for MP4
  • Check timing and readability
  • Final export in your editor

GoPro footage & data sources

Telemetry from your GoPro
or a recorded GPS track.

GPS-enabled GoPro models can supply embedded GPMF. HERO12 Black has no GPS receiver, so speed and route need a separate recording. Use a supported FIT activity exported from Garmin, Wahoo or iGPSPORT, or a recorded GPX track. Reframe and export 360 footage before pairing it with data.

GoPro's telemetry reference explains which streams each model records. An external GPX/FIT activity supplies GPS when your recording lacks it. Brand names are the property of their respective owners; GaugeReel is an independent overlay tool and is not affiliated with GoPro.

The instrument set

What you can show from
GoPro telemetry.

Show speed, altitude, g-force and a GPS route when the required data was recorded. Add a supported activity file for heart rate, power or cadence when it contains those measurements. Choose the numbers that help tell the story of your ride, run or drive.

Composite & export

A transparent layer over your GoPro footage

GaugeReel never re-encodes your GoPro clip. It renders only the gauge overlay and exports a layer with a real alpha channel, so you drop it onto a track above your footage and the instruments sit cleanly over the action.

  • Free: PNG image sequence with a true alpha channel
  • Basic and Premium: ProRes 4444 MOV or VP9 WebM with real alpha
  • Free: chroma-key MP4; remove its colored background in your editor
  • Composite in Premiere Pro, DaVinci Resolve, Final Cut, After Effects or CapCut

Questions

GoPro overlay questions, answered

The specifics of getting telemetry from your gear onto your footage.

Import the original GoPro MP4 into GaugeReel, the desktop app from gaugereel.net, to scan any embedded GPMF telemetry. Available streams depend on the camera and recording. For HERO12 or footage without GPS, add a recorded GPX or Garmin FIT track. Choose a gauge layout, sync it to the footage, then export a transparent overlay for your video editor.
