Recently after installing a new OS, I've noticed that Lightroom really hangs on importing raw videos and also publishing them to my desktop. Importing photos is a breeze, the problem is only with videos. Has anyone else experienced this problem? I wasn't having the lag time before the new OS. Also I was wondering if my large database (382 mb) has anything to do with it? I have searched for a "maximum catalog size" but have found no real answers. Thanks for your help!
I finally stumbled on the answer as to why the videos were hanging on publishing them to my local hard drive. On the publishing manager, the video format should be "ORIGINAL" (I didn't realize they were being published under H.264 - max quality). Once I changed this to Original, the videos published lickety-split! Still investigating why they take forever to import; will try importing straight from the camera (vs. the memory card & card reader) to see if there's any time difference. Hope my solution helps others who've experienced this issue!
