mp4 location tagging for iPhone

[xo66]

Hi,
I'm looking for a solution for having mp4 on my iPhone with the location tagged.
I've tried with these strings but with no success:

exiftool -xmp:gpslatitude=45.870932 -xmp:gpslongitude=12.271407 example.mp4

exiftool -QuickTime:GPSCoordinates#="45.870932 12.271407 0" example.mp4

Can someone help me?

You will have to be more specific than "no success".

Both of those commands should have written the specified metadata to the file.

This may be  FAQ 3.

"No success" means that on the iPhone I don't see any location tagged.

Right.  OK, so try this:

exiftool -Keys:GPSCoordinates#="45.870932 12.271407 0" example.mp4

Apple software likes things written in the Keys location in videos.

Thanks but nothing happens even with this:

exiftool -Keys:GPSCoordinates=45.870932,12.271407 example.mp4

I disagree

And I'm very sad. Is there anything I have to check in the file?

Did you read FAQ 3?  Also, are you using the most recent version of ExifTool?

I'm using 11.73 running it on Windows 10.
The strange thing is that today i made a video with my iPhone 11 and on Camera Roll the video it's tagged with the GPS Position.
But if I moved it from iPhone to PC and then I syncronize I lose the GPS tagging on Camera Roll. Who knows if I had a Mac what can happen...
