Join Scott Bourne for an in-depth discussion in this video Writing sidecar (XMP) files, part of Migrating from Aperture to Lightroom.
You already mentioned that not all metadata can be embedded so, we're going to need to put that as a companion file. Do you have any suggestions? >> Yes. Thankfully, Aperture did, they figured this out that somebody might want to do something like this someday and they didn't hold that data hostage, which I find commendable about them. >> Yep. >> So we're going to create what's known as a sidecar file and sidecar files have been around forever in Photoshop, and Aperture has them too. So we're going to simply export sidecar files with these TIFFs and PSDs and we're going to show you how to do that.
>> All right. >> Now we have a different scenario. We're working with a PSD file. Since you may have everything from JPEGs to PSDs to TIFFs to RAW files in your Aperture library, there are different methods for moving the metadata from Aperture to Lightroom. In this case, I'm going to say File > Export > Original just like I would as if it were a RAW file but down here I am going to make an important change. I am going to select Create IPTC Sidecar File.
This is very important because that sidecar file gets read by Lightroom when we export from Aperture and import into Lightroom, and that allows all of this important metadata over here to make the trip with the picture. So remember, you have choices that say Don't Include it, Include it, Create Sidecar File. Now what happens if you click Include it? Well, because it's a PSD file and not a RAW file, it doesn't show up. It doesn't make the trip.
You need to go down here and create a sidecar file to make sure that, that happens. And by the way, if you have done audio, you'll want to check this box. And if you want, you can have this thing give you a little alert when it's done, but it's so fast it's not important and we don't have any audio here. So I can click export originals and I will have all of my metadata, because I selected the sidecar file option.
