Monterey 12.2.1 Not all videos/photos imported from XQD (Paid work loss risk)

What it sounds like. I recently imported a bunch of video footage from a paid shoot into lightroom. I had to do this quickly as I was in a rush to format the card and go out. I therefore must have not fully checked that all the files were downloaded, as most of them are not on my Mac. There doesn't seem to be rhyme or reason to which files are there and which aren't.

I've searched my time machine hard drive and it has .ims files for the missing clips. E.G. MOV_7299-a4651d....a802.ims

Appreciate your help!
