FAQ

Where does the location come from?

Phone cameras write a ©xyz atom inside the container, which holds latitude and longitude.

Why is the recording date wrong?

Some cameras write UTC while others write local time; the field is shown as stored.

Is the video uploaded?

No, only the container is parsed in the page.

Files never leave your device

Processing happens in your browser using the File API, WebAssembly and Web Workers. There is no upload endpoint.
