Generators are a class of effects that create (or generate) new video information rather than modify existing video. After you have generated it by rendering, a generated clip can be used just like any other clip. Text is a high-profile member of the generator class of effects; using the text generator to produce titles is covered later in this chapter.
Final Cut Express’s generators include the following:
Bars and Tone, which generates NTSC or PAL color bars and includes a 1-kHz audio tone with an adjustable level.
More Bars & Signals, a suite of specialized color bar patterns and gradients.
Matte, which generates solid, single-color clips.
Render, which generates color gradients and different types of “noise.”
