Every thing worked fine with AP2. I opened the project in APC3, and the video does not a appear in the project window. If a video effect is placed on the clip, it appears. If I removed the clip, it continue to appears. When I reopen the project the video does not appear on a clip where it was put on and removed. It does if I leave an effect on.
I have made no changes to the computer setup. and again it works fine under AP2. I would like to work it under APC3. Adding an effect to every clip is not going to work as there are some 600 clips and the project file size will reach some 35 meg.
