Stephen,
I started over. I took out all of the filters (levels, color match, etc) that I had put in the original clips before I used the Excalibur multicam function on the three cams I was using for this wedding ceremony. Everything looked good after the multicam process. However, even with no filters in the new project I got the “not responding” in Pro 12.
So, now I have a fine computer, Win 8, etc. but I am still having big problems. Now I am wondering if Excalibur is the culprit. Any thoughts? Jim
