I have Lightroom 6 on a 2009 iMac, running latest OS 10.11.4
I am also quite new to Lightroom having moved from iPhoto, to Aperture and now to Lightroom.
Problem: sometimes (but not always, and I cannot work out a pattern to give a clue), video clips will not open properly. I get a black image, and when I click on play, I get sound but no video image.
I have disabled "Use graphics processor" in Preferences/Perforrmance as is recommended elsewhere.
Solution:? Any help appreciated.
Thanks for replying.
I have now updated LR to 6.5.
The videos were taken on a a Canon Ixus and are showing with the .MOV extension. If I go to Finder and open the files in question, they will happily play in Quicktime. But in LR when I try to play the very same files I get a black "picture" and sound only.
I stress this is ony for a minority of my video files. Maybe I should re-import them from the memory card and see what happens. Could the LR catalogue have some faulty data concerning these files?
