Cannot import .MOV files any more
Both the previous version of LR and the newest version 8.0 will not import .MOV files. I have done it successfully many times in previous versions and this is a relatively new phenomenon.
In the Import panel there are no previews available and when I select a .MOV fie and try to import it I get an error message saying 'The movie file contains no video frames (1)'.

If I open the .MOV file in iMovie and save it as an .MP4 then I can import it into LR no problem.
Can anyone suggest why Lightroom isn't able to import .MOV files anymore?
iMac OS Mojave 10.14.1.
