See where and when a video was recorded, and on what device, before you share it. Then remove those details without changing a single frame. Your video never leaves this device.
Often. iPhones and many Android phones store where a video was recorded when the camera app has location access. Action cameras, drones and dash cams can go further and record a position for every moment of the video in a separate data track. The location can usually be pinned down to within a few metres, enough to identify a home.
No. For MP4 and MOV files the metadata is blanked where it sits: each section is marked as empty space and filled with zeros, keeping its size, so the rest of the file stays byte-for-byte the same. Nothing is re-encoded, so quality is identical and even large videos take seconds.
Many large platforms strip location from the copy they show to others, but you cannot always tell which ones do, and the original you upload may still be kept by the service. Videos sent as files or documents in messaging apps, shared through cloud links, AirDrop or email usually keep everything. Removing it yourself first is the safe habit.
MP4 and MOV store creation times in a field that should be in UTC, but some cameras write their local clock time there instead, and some editing apps reset it. Apple devices also store a separate date that includes the local time zone, which is the more reliable of the two.
This tool shows what they contain, but cannot remove it in place. The free tool ffmpeg can make a clean copy without re-encoding; the page shows the exact command when you open one of these files.
