What the tools support
Professional production software can preserve and edit metadata such as XMP. Google also documents IPTC image metadata for creator, credit and licensing information.
What is not established
Embedding large keyword lists into exported media files is not documented by Google as a direct ranking shortcut.
Ozmov practice
Preserve useful production and rights metadata, but put search effort into the visible page, relevant copy, captions, thumbnails, structured data and accessible media delivery.
