Encoding multiple GPS recordings to a mp4 video

[Nitram95]

Hey, I have 1 minute long mp4 videos and I would like to add GPS metadata with 1s period (60 GPS position recordings). Each GPS metadata recording should be marked with a Sample Time item (video time offset).
I am able to add GPS metadata with:

Code Select Expand

exiftool -geotag=my_log.gpsx -geotime="2023:10:17 7:41:12-05:00" my_video.mp4or

Code Select Expand

exiftool -geotag=my_log.nmea -geotime="2023:10:17 7:20:12-05:00" my_video.mp4but it adds just one GPS recording and ignores the others.
Is it possible to achieve that with exiftool? Thank you.

The problem is that there really isn't a standard for embedding a GPS track in a video*  Currently, exiftool reads 66 different ways that a GPS track can be in a video and there are about half a dozen more in which the format hasn't been decoded.

*Technically, there is a standard by Google but I've never found any software that can embed a track.

About all you can do is set the Quicktime:GPSCoordinates or the XMP:GPSLatitude/XMP:GPSLongitude.  Your command probably does the later unless you've updated to the most recent version of exiftool, which will set both.

And does exiftool support adding multiple Longitudes/Latitudes in one video? This is the part I am missing.

No.  The tags I listed only appear once in the file.
