How to recover iPhone videos converted to .jpeg after transferring to MacBook?

I transferred all my photos and videos from my iPhone to my Macbook Finder due to full iCloud storage.

How did you transfer them?? Via drag'n drop from Photos which should not be used because it might copy only thumbnails? Can you try the copy again via File > Export or from iCloud web Photos export?

I guess that is the same as drag 'n drop which has obviously copied only .jpeg thumbnails of those movies (if their file size is tiny they are thumbnails of the much larger movies). Can you try the copy again via File > Export or from iCloud web Photos export? Or from a backup?

Check if they are still in the iCloud web Photos trash. If not, you might ask official Apple support if the movies could somehow still restored from Apple's servers. And you really do not have any local Time Machine or other backup?
