Hello,
I'm trying to add MP4 videos geolocation data using "GPSCoordinates" metadata tag.
The problem is that I don't understand what is the expected format.
Based on previously found examples on this forum:
"exiftool(-k).exe" -Keys:GPSCoordinates="141.60508055555, 42.626330555555" DV_1_MOVIE0014_1_ddv3_stab_chf3.mp4
1 image files updated
It seems to work, but actually only latitude is written.
"exiftool(-k).exe" -gpscoordinates DV_1_MOVIE0014_1_ddv3_stab_chf3.mp4
GPS Coordinates : 141 deg 36' 18.29" N,
I get the same result with '-n' and without comma...
Is there a reason for this behavior?
Thanks.
141 degrees north is not a valid latitude.
ExifTool could definitely handle erroneous inputs like this better.

I'll add a patch so you'll get a "Latitude out of range" warning for this case in version 12.73

Oops! My mistake indeed I mixed up Latitude and Longitude.
Thank you for this error case "fix" anyway :)
Works better like this:
"exiftool(-k).exe" -Keys:GPSCoordinates="42.626330555555, 141.60508055555" DV_1_MOVIE0014_1_ddv3_stab_chf3.mp4
1 image files updated
"exiftool(-k).exe" -gpscoordinates DV_1_MOVIE0014_1_ddv3_stab_chf3.mp4
GPS Coordinates : 42 deg 37' 34.79" N, 141 deg 36' 18.29" E
I was also wondering if there is a way to input the coordinates in degrees, for example:
42°37'35.37" N 141°36'16.44" E
Is it possible?
Thank you.
I'm going to use an argfile to avoid the whole quoting issue. The command would be
exiftool -@ my.args FILE
with this my.args file:
-gpscoordinates=42°37'35.37" N, 141°36'16.44" E

Even though this is about the Quicktime tag and not the GPS tags, I assume that this line from the GPS tags page (https://exiftool.org/TagNames/GPS.html) applies?
QuoteExifTool is very flexible about the input format when writing lat/long coordinates, and will accept from 1 to 3 floating point numbers (for decimal degrees, degrees and minutes, or degrees, minutes and seconds) separated by just about anything ...
Yes, thanks. That documentation applies. Also FAQ 14 (https://exiftool.org/faq.html#Q14). For GPSCoordinates you have 2 coordinates in this format separated by a comma, which introduces a restriction that the individual coordinates themselves may not contain a comma.

That's clear! Thanks a lot for your detailed answers.
Heh, tried to push it with this silly attempt
C:\>exiftool -P -overwrite_original -GPSCoordinates="42 robots fighting 37 aliens at 35.37 N Main Street, 141 pirates partying with 36 ninjas at 16.44 E Grand Ave" Y:\!temp\Test1.mp4
1 image files updated
C:\>exiftool -G1 -a -s -GPSCoordinates Y:\!temp\Test1.mp4
[ItemList] GPSCoordinates : 42 deg 37' 35.37" N, 141 deg 36' 16.44" E
I give the edge to the aliens. But if the pirates/ninjas are smart they'll wait until the aliens are done with the robots, then they should be able to take care of the rest.

Edit: But note that the N/S and E/W aren't actually working because they have to come at the end of the coordinate. NE is the default. SW would be a better test.
