112 Chapter 8 Previewing and Fully Rendering Your Titling Movie
Optimizing Preview Performance
LiveType works with bitmapped elements that consist of pixels of information, as
opposed to vector-based data. While this format is what makes possible the wide range
of effects offered in LiveType, file sizes are inevitably large, and the time it takes to
render a preview can become lengthy.
Rendering time is affected by each layer of complexity added to a project, including
the number and file size of project elements, the number of effects applied to each
element, and the duration of the movie (that is, the number of frames to render).
Quality Settings for Previews and Movie Output
LiveType offers four levels of rendering quality, set in the Project Properties dialog, to
help you manage the amount of time you spend generating previews. Naturally, a
lower-quality preview takes less time to render.
A wireframe-quality preview represents each element as an empty bounding box,
much like the small Live Wireframe Preview in the Inspector. Draft, Normal, and High
Quality settings differ only in the resolution of the preview. A draft-quality Canvas
appears slightly grainy at 100 percent zoom. A draft-quality preview movie appears
small on the screen.
You may find that, as you build your project, it is useful to adjust the quality settings
several times, to suit your preferences.
To adjust the quality settings for viewing the Canvas, generating preview
movies, and rendering a final movie:
1 Choose Edit > Project Properties.
2 In the Quality area of the dialog, choose the quality level for each of the three modes.
