Query: After Effects 4.1 - More Intuitive and Powerful

Adobe has improved on what is likely one of the most powerful video compositing programs available. After Effects 4.1 has set a standard for manipulating video, text and graphics.The improvements in this upgrade include more powerful and easier to use matte tools, many small interface tweaks and a few important bug fixes.The overall program, though still difficult to master becuause of it's power and number of features, is much more intuitive. It also seems much more rubust on NT than in the past. Render and preview tools have improved, though rendering is still the biggest downside to such a powerful program.
