  • Puts MP4/MOV in the preview, allows you to move and scale the video under the overlay.
  • Synchronizes the video with the track by GPS metadata, and if there are no coordinates, by the shooting time.
  • Includes a preset Cinema HUD with arcs, timer, progress bar and route.
  • Exports transparent .mov with HEVC Alpha or ProRes 4444 Alpha.

Requirements

Mac on Apple Silicon: M1, M2, M3, M4 or newer. The minimum version of the system is macOS 13 Ventura.

The build is signed ad-hoc, without notarization: macOS may ask you to confirm the launch manually.

Quick start

How to set and create an overlay

  1. 01

    Download DMG

    Open the file FATRACING-Telemetry-Mac-AppleSilicon-macOS13-2026-06-27-2259.dmgand drag the application to Applications.

  2. 02

    Launch the app

    If macOS swears at an unknown developer, right-click on the application and select Open.

  3. 03

    Upload an activity

    Drag FIT or GPX to the application window or click "Open FIT/GPX". The export itself does not start.

  4. 04

    Add a video

    Download MP4/MOV as a backing, click "Sync." and check the result with the "Play" button.

  5. 05

    Customizing the overlay

    Select a preset, a segment, arrange widgets, correct signatures and colors, then click "Make MOV".

Which codec to choose

HEVC with alpha — compact file by default. Good for most quick scenarios.

ProRes 4444 with alpha — the file is larger, but the installers often see transparency without surprises. For Adobe Premiere, it's better to start with it.

If macOS writes "damaged"

Open Terminal and execute the command:

xattr -dr com.apple.quarantine "/Applications/FATRACING ТЕЛЕМЕТРИЯ.app"

After that, launch the application again.
