Since I upgraded to Lightroom 5.7 on a Windoiws 8.1 PC, I can no longer import MOV movie files. In the past I was able to import them and it does not appear that I have changed anything. The only special characters in the filename is a dash . Many other file types work fine with the dash in the filename.
Why can't you import them? What is stopping you? What happens? What is the error message?
Well as it turns out, I believe it was a corrupt QuickTime. When I found another computer with Lightroom, I tried the same files there. I got a dialog that said QuickTime was missing. When I installed QuickTime the files imported correctly.
Back at my comnputer, I attempted to open the files in QuickTime and that installation was obviously corrupted. Other video files loaded but not the MOV files. I reinstalled QuickTime and now the files import properly.
Thanks for taking the time to respond. It never occurred to me it was another program; I just assumed it had to be the upgrade to Lightroom 5.7.
