How to use it, and how to record a good test clip

Recording the best test clip

Props can stay on. What matters is 1–3 seconds with the quad sitting still and the motors disarmed. Do this as follows:

Set the camera FOV to 'Wide' and Recording Stabilization to 'Off', so the gyro data is recorded in the video file.
Disable low-power mode: go to Settings → Control and set Auto Low-Power State Of Air Unit to 'Off'.
Start recording from the top drop-down menu.
Record 10 seconds of video to the goggles' storage or the SD card.

A clip that is in flight the whole time can still be checked, but the result is less accurate because it comes only from the camera serial. That result is shown as "Likely …" with Low confidence.

Checking a clip

Drop the .MP4 above, or use Choose file(s) / Choose folder. A result appears for each clip. Large files take a few seconds.
Use the original file straight from the card or goggles. Trimmed or re-exported files lose the gyro data.
Use it offline: click Install app at the top, or use the install icon in Chrome or Edge's address bar. It then opens from your Start menu or desktop like a normal program and works with no internet. Clips are never uploaded, even when you're online.
Know which gyro you have? Open Submit feedback under a result and click Save data & open form. In the form, choose the gyro, upload the saved file, and submit. This is how the detection gets better.
Sharing a big clip? Analyse it, then click Export gyro data. This saves a small .o4gyro.json file (about 4 MB per minute of footage) with the gyro track and file details but no video. Anyone can open it in this app.
