Copy GPS to Geolocation city tags in movies

[wywh]

What is the best way to copy GPS to geolocation city tags in movies?

This command does not work because it overwrites existing Keys:GPSCoordinates with the Geolocation GPS which might be several kilometers away from the initial spot:

Code Select Expand

exiftool -overwrite_original '-Keys:XMP-photoshop:XMP-iptcCore:Geolocate<GPSPosition' movie.mp4
I tried to omit overwriting it with '--Keys:GPSCoordinates' but that did not seem to work.

Is this the best way to do it:

Code Select Expand

exiftool -overwrite_original '-Keys:XMP-photoshop:XMP-iptcCore:Geolocate<GPSPosition' -TagsFromFile @ -Keys:GPSCoordinates movie.mp4
None of my apps read XMP in movies so I might omit 'XMP-photoshop:XMP-iptcCore' from that command.

With images this is not a problem and this works OK (I do not write IPTC because it lacks CountryCode and it might be better to stop writing also IPTC anyway):

Code Select Expand

exiftool -overwrite_original '-XMP:Geolocate<GPSPosition' image.jpg

IPTC:Country-PrimaryLocationCode is the equivalent of XMP-iptcCore:CountryCode, but I agree with the second point.

IPTC:Country-PrimaryLocationCode is the equivalent of XMP-iptcCore:CountryCode

Thanks for the note. My app does not read that IPTC tag while it does read the corresponding XMP tag. FWIW there is a warning if two letter code is used:

Code Select Expand

exiftool -overwrite_original -IPTC:Country-PrimaryLocationCode=US image.jpg
Warning: [Minor] String too short for IPTC:Country-PrimaryLocationCode (padded) - image.jpg

Hi Matti,

Is this the best way to do it:

Code Select Expand

exiftool -overwrite_original '-Keys:XMP-photoshop:XMP-iptcCore:Geolocate<GPSPosition' -TagsFromFile @ -Keys:GPSCoordinates movie.mp4

I think what you want is simply:

Code Select Expand

exiftool -overwrite_original '-Geolocate<GPSPosition' movie.mp4
As per the table here, this will write:

XMP:City
XMP:State
XMP:CountryCode
XMP:Country
Keys:LocationName

Which should do the same thing as your command.

You raise an interesting point about Keys overwriting Keys:GPSCoordinates when input coordinates are specified.  I should think about this.

Code Select Expand

exiftool -overwrite_original '-Geolocate<GPSPosition' movie.mp4

Thanks for reminding me that this feature was added in 12.81.

The same simple command works also for images:

Code Select Expand

exiftool -overwrite_original '-Geolocate<GPSPosition' image.jpg

I'll patch ExifTool 12.88 to write Keys:GPSPosition only when an input city name is provided, and Keys:LocationName only with input GPS when the Keys group is specified.
