ios12.1 exports movies in unrecognizable format
After updating my iphone 7+ to ios 12.1, I can no longer export movies into my Macs. Well, Photos says they have been sucessfully imported, but with a zero-second length and blank thumbnail, and while providing a popup warning that the files are in an unrecognizable format. I have tested this on two iMacs, both using El Capitan 10.11.6.
