Good evening,
I would like to add GPS information to videos in .mp4 format. Unfortunately, Windows Photos app and my Android Gallery does not recognize it.
I looked up how videos that already have working GPS information look. I did that with the help of the "-v" parameter:
...
| UserData (SubDirectory) -->
| + [UserData directory]
| | GPSCoordinates = ...+58.9086+6.5558/
| Meta (SubDirectory) -->
| + [Meta directory]
...
Without "-v":
GPS Coordinates : 58 deg 54' 30.96" N, 6 deg 33' 20.88" E
If I now use the command
exiftool -UserData:GPSCoordinates="+27.6640,-81.5751" file
it looks like this:
| UserData (SubDirectory) -->
| + [UserData directory]
| | GPSCoordinates = .+27.664-081.5751/
| Meta (SubDirectory) -->
| + [Meta directory]
Without "-v":
GPS Coordinates : 27 deg 39' 50.40" N, 81 deg 34' 30.36" W
And unfortunately this is not recognized by the mentioned programs. What can I do?
By the way, everything works smoothly with images.

Probably nothing. Unless you can find a file that does show GPS coordinates in those files, it's quite likely that they don't read such information in video files.
I think I was a little unclear. The top part works and is a video that my phone camera took. The programs mentioned work fine here.
But when I change the GPS information using exiftool on the working video or other videos, it suddenly stops working.
I think this is because it seems to be saved in a different format, since the outputs with the "-v" argument look different:
From camera: GPSCoordinates = ...+58.9086+6.5558/
From exiftool: GPSCoordinates = .+27.664-081.5751/
Is there a way to adjust the formatting? Or could it be something else?
Thanks in advance
What is the -v3 output for the GPSCoordinates tag in the working version? I need to see the binary data for this tag.

Edit: I'll take a guess here: The "eng" language version of the tag would do this. Try writing it like this:
exiftool -UserData:GPSCoordinates-eng="+27.6640,-81.5751" file
Read the 3rd paragraph here (http://exiftool.org/TagNames/QuickTime.html) for an explanation.
Thank you so much.
I had tried that too I think, but apparently always the combination of both. Or I had done something else wrong.
In any case, it works now. Thanks again
P.S. Those other softwares are garbage if they ignore GPS coordinates just because they have an unexpected language code.
It seems that good metadata programmers are hard to come by... ;)
