Export with XMP sidecars into Capture One

[David Brewster]

I realise this might be a Capture One issue rather than a Nitro issue, but I’m wondering if anyone has any experience with this.

I’m exporting a bunch of images (from my Apple Photo library) with various ratings and flags applied in Nitro. I then want to import into Capture One with that metadata. I’m choosing to copy the original plus metadata on export, which seems to do the right thing and create an XMP sidecar. However, on import into Capture One, even with ‘Auto sync sidecar XMP’ turned on, nothing happens. The original image is imported, but with none of the Nitro metadata.

Would appreciate any shared experience on this.

Capture One is tricky with sidecar files. Have you tried using a manual sync on a single image, to test if C1 can actually process the XMP file? (Image > Load metadata or Image > sync metadata)

If that works, but the automatic sync doesn’t work, it’s likely that the background processes during import didn’t complete. C1 doesn’t always warn about that, it seems. You can then manually select all images you’ve imported and use the same manual sync to force C1 to read any sidecar files.

Hope that helps!

I have two thoughts on this:
1) if the files are DNG or JPG, then Capture One probably won’t see the XMP files because of the way Nitro names sidecars. You would need to rename them to match whatever they expect. This is not an issue for proprietary RAW (e.g. ARW, ORF, etc.)

2) There is no XMP standard for flags (location or values), so Capture One won’t read those either.

Thanks to both of you for your responses. All makes sense. Given I’m trying to mirror combinations of rating, flag and favourite, and most of the files in this instance are JPG, HEIC and DNG, I think the easiest way to deal with this is to simply use Nitro’s filters then export and import in batches, reapplying metadata on each batch as I import to C1. That will be a relatively quick process.

I realise now that C1 doesn’t have flags anyway, so even if the XMP standard did support them they wouldn’t come across.

I’ll also experiment with keywords in future.
