To activate the XMP roundtrip for Watched Folders, simply select “Automatic” for the XML Roundtrip option. When selected, it means that a sidecar XMP will be created or updated every time the corresponding master version is updated.
In the case of JPEG files, an additional options lets you control whether the annotations should be written into the files. This is useful as some tools don’t rely on XMP sidecars for non-RAW files but read the metadata from the images themselves.
Activating the roundtrip via XMP lets you use Peakto to add annotations to files and see those annotations propagated to other tools that leverage XMP data.
2.2.2. Annotations and Exporting
When exporting annotated versions from Peakto, the annotated values can be added to the exported images through an option available in the export panel. Choose the appropriate option from the Write Metadata in File dropdown menu. The All Metadata and Exif and IPTC (no GPS) both write custom annotations back to the file.
