How about the warning triangle on a library icon? This happened when I upgraded from 10.4.4 to 10.4.6. I had to copy my project to a new library, and even then it took some finagling to things to work. One clip in the timeline got trashed. Fortunately it was easy to rebuild. Some compound clips turned gray. A 10-frame gap clip was prepended to the primary storyline. Deleting all projects was one way to fix it. A couple of clips had _converted added to their names in the browser in addition to in the Finder. I reproduced the warning triangle when converting other less important libraries, like old backups. Any idea what’s causing this? Oh, and it’s the library conversion that causes the problem, not changing the codec to ProRes 422 (makes sense, of course, but I’ve seen stranger things happen).
