    Hi Phil,

    Ultra newbie here trying to grab gps info from a few mp4 files. I have read through a lot of the sample information, very little made sense but I did find this command line:

    exiftool -a -u -g1 a.jpg

    which I thought would display the file information for me to read, there was also one that ended in .txt. Either way, after dropping the file onto exiftool, the command window opened up, a few seconds later it displayed some information and then immediately disappeared and the tool shutdown.

    And I can't find any text or jpg file that could possibly have the information I am trying to extract.

    What am I doing wrong?

    Regards,

    Rod

    For the most part exiftool is a command line program in which you would open a CMD or PowerShell and run it from there.

    You can create a drag & drop option by renaming the program and placing the options you want to use within parentheses. Using your example, you would rename (or create a shortcut) with the name exiftool(-a -u -g1 -k).exe and then you could drag & drop files onto it. See Running in Windows for more details.

      Hey StarGeek,

      I copied that command into the desktop icon (where exiftools was
      extracted to), dragged and dropped a jpg onto it, it opened a black cmd
      window, then instantly closed.

        Here's an example of how it works here

      maybe if I have them in the same folder?

    Would it be possible for someone to remove the gps co-ordinates from an mp4 file? OK, that might sound "screwy".

    My daughter and Son-In-Law are having domestic problems, enough so that the Police have issued a Domestic Violence Order for him to keep away. Part of keeping away means that any pictures or vids sent to him must not contain GPS co-ordinates.

    Son-In-Law is currently overseas and has requested pics and vids of the kids. So, can someone who understands how exiftools works, run it on a vid that I provide and tell me if it contains gps coordinates?

      Exiftool can remove GPS coordinates from an image, but you might find it easier to use Windows built-in ability to remove personal data. See here

      Removing GPS from a video can be different, depending upon the video. Exiftool can remove a static GPS coordinate, but if the video contains a GPS track, then exiftool cannot remove that as it doesn't edit video streams.

      Using the command line, ffmpeg can do it (see this superuser post) but ffmpeg is very complex.

      An easier option to remove a GPS track would be to use AVIDemux and set it to Copy rather than reencode. See the image in this post for the settings.

    Well, that was definitely easier just using Windows to create copies with no data. Much Appreciated.

    Rod.

    Another option just occurred to me. You could create an Instagram account with the sole purpose of sharing in this case. Instagram will automatically strip away all data for privacy reasons.
