    CS4 Track Matte Key does not work

      Amazingly, the Track Matte Key effect does not work in CS4. Projects with the effect work in CS3, but the same files and same effect properties do not work in CS4.

      To demonstrate this I have a small test available for download. It is a 2-second matte transitioning over two A and B title cards. The A content has a Track Matte Key on Luma over a matte clip.

      This project is available as a 90KB download at


      This zip file contains three files:


      The CS3 version in CS3 correctly transitions A to B.

      Either version in CS4 will show the B content only, no transition.
