I teach TV in a high school and have used Final Cut 1, 2, and 3. Now I hear about FCP Express. Can anyone who actually has used both FCP 3 and Express comment on what features are missing? (We kind of like the many features on FCP 3.) I don't know whether to get Express or wait on FCP 4. Since we get educational pricing, the cost won't make much difference. Thanks, all.
