Photos aren't the only files that carry a map pin. iPhone and Android videos write the capture location straight into the MP4 or MOV container — in the QuickTime ©xyz atom and the mdta location keys — and it travels with every copy you share. MetaMarshal's video tool, at metamarshal.com/video, reads those atoms in your browser and strips them entirely on your device: no upload, no re-encoding, no quality loss, and it handles multi-gigabyte files because the video never has to leave your machine.
