I have proffesional studio photos, but the alignment doesnt recognise a lot of them

So i have to convert that cr2 files into “tif” for example and then it will work?

I have also an archive called .xmp with the cr2 files, i have read about it but i dont know how to use it inside realitycapture. Maybe that can help with the cr2 files?

Thanks for the answers¡
