Copied GPS data doesn't show in Finder and Photos on Mac Sonoma.

[Cares Lodgers]

Hello, experts,
I copied GPS data like this:
exiftool -tagsfromfile SRCFILE -gps:all -wm cg DIR

The original file 1.MOV has valid GPS data, which shows in Finder and Photos.

Data are copied correctly, which I can verify by :
exiftool -s 1.MOV.mp4

It shows identical data to the original 1.MOV.

But 1.MOV.mp4 doesn't show any GPS data in Finders, by CMD+I, in More Info section.
Also once imported into Photos, it shows no GPS data either.

Can you help advise?
Thank you.

Hi Cares,

EXIF GPS is nonstandard in videos, and ExifTool doesn't even write this in most cases.  The preferred place for GPS in videos would likely be QuickTime:GPSCoordinates (not sure if the Keys, ItemList or UserData location would be best).  I would try writing that.

Use the command in FAQ #3 on the file that does show GPS data in Finder and look for the group where it is located.  You'll want to copy to that Group:Tag.

You might also find the answer looking through the forums at wywh's posts. They're the expert when it comes to Mac's and videos.

Apple's devices and apps use Keys:GPSCoordinates, and favor Keys also for CreationDate, Title, Author, Keywords, Description, Make, Model, Software, CameraLensModel, and CameraFocalLength35mmEquivalent in movies.
