Generator Parameters
The following sections describe the common parameters and details of each generator.
Parameters in Common
All generators have a reset button and Width, Height, and Pixel Aspect Ratio controls,
which are located in the Generator tab of the Inspector. The controls specific to each type
of generator are discussed later in this chapter.
• Reset: Click to reset the generator to the default settings.
Reset button
• Width: Sets the width of the generator, in pixels. Values range from 1 to the width of
your project.
• Height: Sets the height of the generator, in pixels. Values range from 1 to the height
of your project.
• Pixel Aspect Ratio: Sets the aspect ratio of the pixels drawn by the generator. Values
can be selected from the following options: Square, NTSC D1/DV, NTSC D1/DV
Anamorphic, PAL D1/DV, PAL D1/DV Anamorphic, Anamorphic 2:1, D4/D16, D4/D16
Anamorphic, HD (960x720, 1440x1080) HD (1280x1080), or Custom. When a value other
than Custom is selected, the Pixel Aspect Ratio of that selection is displayed in a value
field next to the pop-up menu. Enter values from 0 to 10000 in the value field. If the
value does not correspond to a preset value (for example, 2 for Anamorphic 2:1), Custom
appears in the pop-up menu.
HUD Controls
In most cases, the HUD controls for each generator are identical to the generator’s controls
in the Inspector. Additionally, the HUDs contain the Opacity and Blend Mode parameters.
Important: The Opacity parameter in the HUD is identical to the Opacity control located
in the Properties tab. This sets the transparency of the generator as a whole. Several
generators contain a separate opacity control in the Generator tab of the Inspector, which
is independent of the Properties tab.
