New Final Cut Pro Generators
Final Cut Pro 6.0 now includes several new generators that can be accessed under the 'Generators menu' within the Final Cut Pro Viewer window.
These generator's can be keyframed within the Control's tab to create animated textures.
To access these new generators, navigate to the bottom right corner of the Viewer menu, and click on the icon that looks like the letter 'A'
You should see several new generator's. If you select one of them, that particular generator will automatically appear in your Viewer window. Click on the Controls Tab within the Viewer window to change the generator's parameters.
Some generator's like 'Membrane' will animate automatically for you. Other's like the 'Len Flare' will remain static. In this case, It is up to you to keyframe the size parameters of the len's flare.
