How to Record GPS Speed and G-Force Video

Updated · Published by VelocityCam (JuMaSt Appworks LLC)

This guide walks through recording a session that keeps GPS speed and telemetry aligned with the video from the first frame to export, whether the phone is securely mounted for pitch, roll, and G-force, or used handheld for GPS-based performance metrics. It uses only what VelocityCam ships with — no external sensors, no cloud services.

1. Mount the phone, or choose Handheld

For pitch, roll, and G-force readings, use a mount rated for the vehicle — vibration and slop in the mount degrade both calibration and video quality. If you would rather record without mounting the phone, switch to the Handheld HUD, which reports GPS-based performance metrics instead of vehicle-relative motion. Either way, point the camera at what you want to see.

2. Wait for a GPS lock

VelocityCam blocks recording until GPS is locked so speed is real from the first frame. If lock is slow, make sure the phone has a clear view of the sky and that location permission is granted.

3. Start recording

Tap Record to start immediately, or long-press for a three-second delayed start (useful when the phone is out of reach). With a mounted phone, automatic record-start calibration references the phone's orientation as level, so pitch, roll, and G-force reflect the vehicle, not the mount angle.

4. Leave it running

Do not interact with the phone while operating a vehicle. The screen and orientation are locked while recording so accidental taps don't matter.

5. Stop, review, export

Stop recording when the session is done. Open the session in the Library, then pick an export destination — Original, 9:16 Vertical, 1:1 Square, or 16:9 Landscape. The chosen HUD is composited into the new file. The original recording is left untouched.

  • Free exports include the VelocityCam watermark
  • Pro exports can remove the watermark, add custom text, or override per export
  • Use High export quality for archival, Balanced or Fast for social

FAQs

Do I need cell service?

No. Recording, playback, and export are offline. Only sharing to a social app or opening the launch website uses the network.

Can I record without audio?

Yes. When audio is turned off, VelocityCam does not need microphone permission.
