Kyno currently only relies on FCP7-XML to transfer metadata to Premiere Pro. Some metadata is either not supported by FCP7-XML or Premiere expects it to be in XMP, either embedded in the file (for certain formats like mov, png) or as a sidecar file (e.g. for MXF).
We are working on a full XMP metadata integration with Adobe Tools like Premiere Pro. We'll announce it, once it is in place.
