Is there a way to delete all GPS metadata from a MP4 file?
I found this command another thread but it will not work for my one MP4 video file.
exiftool -overwrite_original "-gps*=" "ShortVideo.mp4"
Any tips will be most appreciated!
As I said here (https://exiftool.org/forum/index.php?topic=12442.msg67309#msg67309), that video has GPS data in the LocationInformation tag. You'll need to remove that tag as well if you've upgraded your exiftool.
But exiftool doesn't have the ability to strip GPS data that's embedded in the stream. To remove an embedded GPS track you'll have to remux the file with FFMpeg.
I installed exiftools in Wine by placing the exiftool.exe into my Videos directory and I am using the terminal in Wine and this is what happens when I enter in this command which is the same command but modified with the overwrite original command but it does not seem to find the file in the directory. Even with the overwrite original removed from the command I still says it cannot find the file. I even tried it on a friends Windows computer today and it does not find the file for some reason.
The file is in the directory and when I use exiftool "ShortVideo.mp4" it returns the metadata of the file.
Z:\home\jacob\Videos>exiftool -overwrite_original '-LocationInformation<${LocationInformation;s/Alt=-?\d+\.\d+/Alt=/}' "ShortVideo.mp4"
File not found.
I have no idea about what would happen under Wine, but if you tried it on a Windows computer, you'll need double quotes around each parameter.
Also, as I said here (https://exiftool.org/forum/index.php?topic=12442.msg67312#msg67312), the altitude entry appears to be required, as exiftool would not write the LocationInformation without it when I tried to remove the altitude.
LocationInformation is a binary data structure, so altitude always exists. The best you can do is set it to zero.

Ah, good to know. I was assuming it was a simple string.
I am unable to delete the LocationInformation metadata in general. How would I delete this and all other metadata from the Short Video file?
$ exiftool -overwrite_original "-LocationInformation=" "ShortVideo.mp4"
Warning: Sorry, LocationInformation is not writable
Nothing to do.
Update to a more recent version of ExifTool.

Excellent, this command now works like a charm which will delete all GPS and location metadata from a video file
exiftool -overwrite_original "-gps*=" "-LocationInformation=" "ShortVideo.mp4"
Under the ExifToolGUI it seems ->Modify -> -remove ALL metada gps data works but ticking GPS alone doesn't seem to.
Windows JPG files gps can be removed using file properties.
Not sure if this helps.

ExiftoolGui is
extremely outdated and no longer supported (as per the stickied thread (https://exiftool.org/forum/index.php?topic=4553.0) in that subforum). Exiftool didn't even have the ability to edit video files when it was last updated.
