Trouble Populating QuickTime:GPSCoordinates Field

[teddimagg]

Hello

I am currently working on a Node.js project that requires the addition of location metadata to .mov and .mp4 video files using ExifTool. All of these video files are QuickTime formatted. Despite my code executing without errors, I'm facing a recurring issue where the QuickTime:GPSCoordinates field (equivalent to com.apple.quicktime.location.ISO6709) remains unpopulated in the final output.

Here is the relevant part of my code:

const exifObject = {
  'CreateDate': creationDate,
  'DateTimeOriginal': creationDate,
  'QuickTime:CreationDate': creationDate,
  'QuickTime:GPSCoordinates': iso6709Coordinates
};
await exiftool.write(fileName, exifObject, ['-overwrite_original']);

The iso6709Coordinates are in the ISO 6709:2008 format.

I am not sure why the QuickTime:GPSCoordinates field isn't populating as expected. Is there something that I may be missing or doing incorrectly in my code? Any guidance on this matter would be greatly appreciated.

Thank you in advance for your assistance,

Looks like you want the Keys group instead of QuickTime? https://exiftool.org/forum/index.php?topic=10081.0

Also: make sure you check out

(You may need to specify latitude and longitude separately)
