• Resolution: This submenu sets whether proxy scrubbing is enabled, and also sets the
quality level of the Canvas. Reducing the resolution improves playback performance.
The current setting is indicated with a checkmark beside the menu item. The menu
items include the following:
• Dynamic: Reduces the quality of the image displayed in the Canvas during playback
or scrubbing in the Timeline or mini-Timeline, allowing for faster feedback. Also
reduces the quality of an image as it is actively modified in the Canvas. After playback
or scrubbing is stopped, or the modification is completed in the Canvas, the image
quality is restored (based on the Quality and Resolution settings for the project).
• Full (Shift-Q), Half, or Quarter: Each lower setting further degrades the image.
• Quality: Sets the display mode for objects in the Canvas, such as text and images, to
Draft, Normal, Best, or Custom.
• Draft: Renders objects in the Canvas at a lower quality to allow optimal project
interactivity. There is no antialiasing.
• Normal: The default setting, renders objects in the Canvas at a medium quality.
Shapes are antialiased, but 3D intersections are not.
• Best: Renders objects in the Canvas at best quality, which includes higher-quality
image resampling, antialiased intersections, and antialiased particle edges. This option
slows down project interactivity.
• Custom: Allows you to set additional controls to customize render quality. Choosing
Custom opens the Advanced Quality Options dialog. For information on the settings
in the Advanced Quality Options dialog, see Advanced Quality Settings.
Tip: When working in your project, work in Draft or Normal for better interactivity.
When you are ready to export your project, use Best or Custom.
• Render Options: This submenu contains rendering controls that typically impact playback
speed. Turn these items off to improve system performance.
• Lighting: Turns off lighting to improve performance. When lighting is enabled, a
checkmark appears beside the menu item. (Option-L)
• Shadows: Turns off rendering of shadows to improve performance. When shadow
rendering is enabled, a checkmark appears beside the menu item. (Option-Control-S)
• Reflections: Turns off rendering of reflections to improve performance. When reflection
rendering is enabled, a checkmark appears beside the menu item. (Option-Control-R)
• Depth of Field: Turns off depth-of-field rendering to improve performance. When
depth-of-field rendering is enabled, a checkmark appears beside the menu item.
(Option-Control-D)
• Motion Blur: Turns off motion blur rendering to improve performance. When motion
blur rendering is enabled, a checkmark appears beside the menu item. (Option-M)
