If you have metadata related to a RAW file in a standard metadata format like XMP (Extensible Metadata Platform), then Capture One will automatically reload the metadata and merge the .XMP sidecar with the metadata already created in Capture One.
Capture One can read and store metadata in the following four formats: Embedded EXIF, Embedded IPTC-IIM, Embedded XMP, and .XMP Sidecar file – these four types of metadata will be automatically updated and read.
To activate or deactivate auto-sync sidecar XMP, go to the main menu and select Capture One -> Preferenze (macOS) or Modifica -> Preferenze (Windows). Click on the Immagine icon in the Preferenze dialog box.
Then choose one of the three options from the Sincronizza Automaticamente Sid... drop-down menu in the Metadati section.
- Sincronizzazione Completa will create and update the XMP sidecar files with any metadata changes. Any information present in the XMP that is not present in Capture One will be loaded. It is a two-way sync.
NOTE: Using Full Sync and working with a large collection of new images can hinder performance. In this situation, it's recommended to use the "manual" sync commands such as Immagine -> Sincronizza Metadati and Immagine -> Scarica Metadati. This will achieve the same end result but without the background sync process slowing things down.
- Carica will load the information from any XMP sidecar file into the .cos (session) or cocatalogdb (catalog). It will not update the XMP with changes from Capture One. It is a one-way sync.
Preferisco includere XMP al di sopra do IPTC toggles the preference when the two sets of data are present in the XMP file; the legacy IPTC fields or XMP fields. You can find more info on the difference in this article: XMP and IPTC
Preferisci Sidecar XMP al posto dei Metadati incorporati toggles the preference between metadata information in sidecar XMP files (in either IPTC or XMP schema) over the XMP information embedded in the source file.
NOTE: Above all, Capture One will never write metadata to source files; all metadata changes are done via proxy file.
