Different behavior between versions?

[jo9817]

I have two exiftool versions installed on my Mac:
/usr/local/bin/exiftool -ver --> 12.52
Downloaded newest version to: /Users/jo/Temp/Image-ExifTool-12.92. Here I deleted everything except the exiftool-file and the lib-folder:

Code Select Expand

-rwxr-xr-x@ 1 jo  staff  326663 25 Jul 02:25 exiftool
drwxr-xr-x@ 4 jo  staff    128 25 Jul 02:40 lib

I want to set the -headline tag:

With the version in /usr/local/bin:

Code Select Expand

/usr/local/bin/exiftool -headline="xxxxx" /Users/jo/Temp/20240819-175346.HEIC
    1 image files updated
/usr/local/bin/exiftool -headline /Users/jo/Temp/20240819-175346.HEIC
Headline                        : xxxxx
and the same with the 12.92 version:

Code Select Expand

./exiftool -headline="xxxxx" /Users/jo/Temp/20240819-175346.HEIC
    0 image files updated
    1 image files unchanged
./exiftool -headline /Users/jo/Temp/20240819-175346.HEIC
and now with the 12.92 version and a .jpg instead of the .heic:

Code Select Expand

./exiftool -headline="xxxxx" /Users/jo/Temp/20240819-175346.jpg
    1 image files updated
./exiftool -headline /Users/jo/Temp/20240819-175346.jpg
Headline                        : xxxxx

Can this be a bug in the 12.92 version?

Jan. 4, 2023 - Version 12.53
  - Changed priority of XMP when reading/writing HEIC files so that it is no
    longer preferred as with other QuickTime-based formats

You now have to specify XMP:Headline to write this to an HEIC file.

thanks Phil!
ok. I see. Is this true only for .heic files?
Can I use this XMP:Headline for all type of files (.cr3, .jpg, .arw, ...)?
As I don't want to distinguish the camera type for updating the images.
Thanks!

Use XMP:Headline to write XMP:Headline to any type of file.

If you don't specify XMP, then ExifTool will default to IPTC:Headline for most formats.  The exception is QuickTime-based formats excluding HEIC.

XMP:Headline should be preferred since the old IPTC NAA format is becoming obsolete.

If you need to double check, you can look at the Supported File Types table. It will show you which file types support XMP data.
