Geolocation disappears after video conversion using MacOS 12.6

You can insert GPS to .mp4, .m4v or .mov with a command like:

exiftool -m -P -n -overwrite_original_in_place -Keys:GPSCoordinates='-36.6101 -66.91515 119.9' movie.mp4

...or with commas:

exiftool -m -P -overwrite_original_in_place -Keys:GPSCoordinates='-36.6101, -66.91515, 119.9' movie.mp4

You can omit the altitude at the end.

Check the result with QuickTime Player or Photos.app or exiftool:

exiftool -a -G1 -s -n -ee -Location:All movie.mp4

...or:

exiftool -a -G1 -s -ee -Location:All movie.mp4

Notice that Google Photos might not show positions in decimal degrees DD with more than 5 decimals after the dot. A value in decimal degrees to an accuracy of 4 decimal places is accurate to 11.1 meters (+/- 5.55 m) at the equator. A value in decimal degrees to 5 decimal places is accurate to 1.11 meter at the equator.

> copy the coordinates to the properties of another video file

Copy all possible metadata tags from .mov to a same name .m4v in the same folder and set file dates:

exiftool -TagsFromFile '%-.0f.mov' -All:All *.m4v -execute '-FileCreateDate<QuickTime:CreateDate' '-FileModifyDate<QuickTime:CreateDate' -common_args -m -P -overwrite_original_in_place .

Fine-tune the command to copy between different file suffixes or to copy only GPS tags.

Skip to the line beginning "Using exiftool via the command line..." in this page:

Matti Haveri already supplied the solution with exiftool. (Exiftool is not supplied with Macos, you will have to download it.)

Which conversion tool? Which conversion options?

Which source and destination video formats?

Which tagging is needed depends on which video format is in use.

exiftool supports at least some video formats (e.g. MP4) and can manipulate some metadata.

There are other means to geolocate recordings.

Please do not use the code tags <> for text.

In general, exif data - such as gps coordinates - is not handled well in video files. You should just plan to re-save the coordinates when you convert.

"Maybe you can somehow copy the coordinates 
to the properties of another video file without using commands?"

You can wish it so, but I doubt that will do anything.

You could probably write a script to do it.

And please don't paste your text in code tags.

Your sentence got cut off.

Can you provide more details? What apps are you using?
