When uploading a real recording, there is a good chance your location & therefore possibly your identity can be revealed from the footage itself.

You can triangulate low volume background sounds such as air planes: https://cybernews.com/privacy/aircraft-doppler-audio-geolocation-privacy/

You can check the position of the sun/moon/stars, shadows, weather...: https://www.bellingcat.com/resources/2020/12/03/using-the-sun-and-the-shadows-for-geolocation/

If Streamers & Journalists CAN do it, government agencies ARE doing it.

If you need privacy be aware of this when recording / editing friends <3

Not any air planes it needs to be a propeller plane.

I've watched the full video and from what I understood, it does not need yo be a propeller plane. They recognized a propeller plane from the audio, and used this info to narrow down the ads-b dataset, but it could have worked with any other type of plane as long as you can find a Doppler curve in the spectrogram

Anything that you can use that has a Doppler shift and is detectable by a camera will and can be used to locate. In the way it was done on the video it was layered with aircraft traffic. Even with a jet engine it will still have a Doppler effect. Unless you’re flying a glider that is silent you can be found. That ONLY by just this method.
