[File]          MIME Type                       : video/quicktime
[QuickTime]     Major Brand                     : Apple QuickTime (.MOV/QT)

I'm just wondering why exiftool will create offsettimeoriginal but not gpsaltitude to the .mov file (.jpg file done as well to check the command is correct).  There is already some exif in the .mov file.

Secondly,  if I just throw quicktime:datetimeoriginal at a .jpg using the API, will that be OK and exiftool will cope or do I need to test for the file type?

I haven't responded for a while because I will need to do some work checking various samples to be able to answer this.

Secondly,  if I just throw quicktime:datetimeoriginal at a .jpg using the API, will that be OK and exiftool will cope or do I need to test for the file type?

ExifTool will handle it.

That was the expected answer.
