Hello, How to cleanly add GPS metadata to a movie (.mp4 or .mov) ?
If we can not do it with exiftool, is there any other tools who can do it?
I tried like this :
ExifTool.exe -GPSLatitude=10 -GPSLatitudeRef=N -GPSLongitude=15 -GPSLongitudeRef=E mymovie.mp4
but it's seam to not work with amazon photos. What did I forget to do ?
Thanks you by advance!
That command will set the XMP GPS coordinates, which few programs other than Adobe ones will read. Also, the *Ref tags don't exist for XMP. The direction is included in the main tag.
For videos, you need to set the GPSCoordinates tag, which includes all three coordinates, Latitude/Longitude/Altitude.
Google is picky, though, and you shouldn't use more than five decimal places or Google may ignore the coordinates.
Your command would be something like
exiftool -GPSCoordinates="40.6892, -74.0445, 10" mymovie.mp4

So you mean for movies no need to do
ExifTool.exe -GPSLatitude=10 -GPSLatitudeRef=N -GPSLongitude=15 -GPSLongitudeRef=E mymovie.mp4
but instead I must do
exiftool -GPSCoordinates="40.6892, -74.0445, 0" mymovie.mp4
right?
one question, when i look Iphone movies (.mov) i saw that the GPSCoordinates is in "Keys" section and when I look an android movie (*.mp4) I see that the GPSCoordinates is in the "userdata" section. when I set the GPSCoordinates with exiftool -GPSCoordinates="40.6892, -74.0445, 0" mymovie.mp4 i saw that the GPSCoordinates is set in the "itemlist" section. Is this matter? what is exactly a section or group? do I need to do :
exiftool -Keys:GPSCoordinates="40.6892, -74.0445, 0" -Userdata:GPSCoordinates="40.6892, -74.0445, 0" -Itemlist:GPSCoordinates="40.6892, -74.0445, 0" mymovie.mp4
to be compatible with everyone ?
On the net I saw also some screenshot where the GPSCoordinates is set in the "quicktime" section, but I don't know how to do this with exiftool ?
QuickTime is the overall format and the family 0 group for all of these tags. (See the QuickTime tags documentation (https://exiftool.org/TagNames/QuickTime.html).) The location (family 1 group) that you should use depends on the software you want to use with this. I can see reference to all 3 locations when I search this forum, so I can't quickly determine which one might be best to use.

Only if you need an Adobe program to read the coordinates in a video file, and you would remove the
GPSLatitudeRef/
GPSLongitudeRef and include the direction in the
GPSLatitude/
GPSLongitude, e.g.
-GPSLatitude="10 N" -GPSLongitude="15 E".

At one point (https://exiftool.org/forum/index.php?topic=11055.msg63477#msg63477), I had a problem with Google Photos not reading
ItemList:GPSCoordinates coordinates, but it worked in the test I did just now. If you want maximum compatibility, you can set all three, it shouldn't cause any problems.

Your command above sets the
GPSCoordinates in all three Quicktime sub-groups, Family 1 groups as Phil says.
SOLVED
Thous shalt not run
exiftool -Keys:GPSCoordinates="..." -Userdata:GPSCoordinates="..." -Itemlist:GPSCoordinates="..." mymovie.mp4with Windows executable version 12.49
but run the -tags in 3 separate commands
Read on for why
I'm trying to manually set the GPS to a compressed mp4
exiftool -Keys:GPSCoordinates="..." -Userdata:GPSCoordinates="..." -Itemlist:GPSCoordinates="..." mymovie.mp4or
exiftool -GPSCoordinates="..." mymovie.mp4
then I ran exiftool thefile.mp4
Original Android file:
...
MIME Type : video/mp4
Major Brand : MP4 v2 [ISO 14496-14]
...
Next Track ID : 3
GPS Coordinates : * deg *' *.*" N, 0 deg 0' *.*" E
Android Version : 10
Track Header Version : 0
...
Avg Bitrate : 8.17 Mbps
GPS Latitude : * deg *' *.*" N
GPS Longitude : 0 deg 0' *.*" E
Rotation : 90
GPS Position : * deg *' *.*" N, 0 deg 0' *.*" E
Compressed file:
...
MIME Type : video/mp4
Major Brand : MP4 v2 [ISO 14496-14]
...
Next Track ID : 202
Track Header Version : 0
...
Avg Bitrate : 2.44 Mbps
GPS Altitude : 0 m
GPS Altitude Ref : Above Sea Level
GPS Latitude : * deg *' *.*" N
GPS Longitude : 0 deg 0' *.*" E
Rotation : 0
GPS Position : * deg *' *.*" N, 0 deg 0' *.*" E
While most GPS properties are set, the attribute "GPS Coordinates" (after Next Track ID ) is still missing from the compressed file and Google Photos could not recognize it nor show the map.
Then I ran
exiftool -Userdata:GPSCoordinates="" mymovie.mp4alone and the attribute "GPS Coordinates" is set and the map appears on Google Photos
PS thou shalt not run
exiftool -Userdata:GPSCoordinates="x,y,H" mymovie.mp4
Google Photos cannot take the 3rd parameter (,H Latitude) as of today 2022-11-5

Thanks for the alert. I usually do not have altitudes in my Google Photos.
Apple's apps use only Keys for GPS and this works today also in Google Photos:
exiftool -m -P -overwrite_original_in_place -Keys:GPSCoordinates='-36.6101, -66.91515, 119.9' movie.mp4I currently make sure that there are min 3 and max 5 decimals after the dot in Google Photos movies because otherwise it might not work.
"ExifTool already has a patch for writing GPSCoordinates because Google Photos didn't accept coordinates with less than 3 digits after the decimal place"
hmm ... but I seemingly can write just one decimal just fine...
exiftool -Keys:GPSCoordinates='-36.6, -66.9, 119.9' movie.mp4
exiftool -a -G1 -s -n -Location:All movie.mp4
[Keys] GPSCoordinates : -36.6 -66.9 119.9https://exiftool.org/forum/index.php?topic=11055.msg67180#msg67180
Some apps might insist that the latitude has 2 and longitude 3 digits before the dot.

I don't think so.
Use the
-v2 option to see what is actually written. The
-n option may drop trailing zeros when reading back.

Oh, thanks for the tip. exiftool 12.49:
exiftool -v2 -Keys:GPSCoordinates='-1, -1, 1' movie.mp4
[...]
- Keys:GPSCoordinates-und = '-36.6101-066.91515+119.900/'
+ Keys:GPSCoordinates-und = '-01.000-001.000+1.000/'
exiftool -a -G1 -s -n -Location:All movie.mp4
[Keys] GPSCoordinates : -1 -1 1
exiftool -a -G1 -s -Location:All movie.mp4
[Keys] GPSCoordinates : 1 deg 0' 0.00" S, 1 deg 0' 0.00" W, 1 m Above Sea Level- Matti
