WaveFilter Image filters can be used to apply the same effect or correction to multiple frames, or they can be animated by loading scenes with existing WaveFilter nulls or by adding individual nulls from the WaveFilter interface. With animated settings you have access to eighteen separate nulls, giving you the maximum flexibility possible. You can mix and match effects to tweak every bit of quality out of your images. Using animated settings with null objects opens up a wide world of image processing magic.
By using null objects with WaveFilter, you add the ability to animate the same settings you set on the WaveFilter interface. Unless you are already familiar with how to use animated nulls, we recommend you get use to the WaveFilter Image interface first. Learn one null object or one set of null objects at a time. Once you grasp the fundementals of using animated null objects, you may find yourself rarely using the WaveFilter Image interface controls. Instead, you may choose to load scenes you have saved with your favorite animated null settings. Null scenes are similar to using the equalizer on your stereo, but for image effects rather than sound.
In the following tutorial we will do a simple 120 frame animation that fades from black, holds and fades to black by using WaveFilter’s Bright% filter with nulls. We will explain how to add nulls directly from the WaveFilter Image interface, how to load and use the null sets located in the WaveFilter Image directory and how to envelope the nulls through LightWave’s Motion Graph.
