SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
HEIC is a very proprietary format, Exiv2 does not support write. ExifTool only support writing in current versions. We plan problematic formats in the future with ExifTool to write. Maik
