Deselect the Continuously Rasterize switch for an Illustrator file until you need to view or render it in detail.
This prevents After Effects from rasterizing the entire file after each change.
See “Using the Collapse Transformations/Continuously Rasterize switch” on page 168 and “To continuously
rasterize an Illustrator file” on page 92.
Improving performance by modifying screen output
You can improve performance in many ways that don’t affect how After Effects treats your project data, only how
output is drawn to the screen as you work. Although it is often useful to see certain items and information in your
workspace, After Effects must use memory and processor resources to update this information, so be selective in
what you choose to display as you work. You will likely need to see different aspects of your project at different points
in your workflow, so you may apply the following suggestions in various combinations at various stages.
Do any of the following:
Close unneeded panels.
After Effects must use memory and processor resources to update open panels, which may slow the work that you
are doing in another panel.
Create a region of interest.
If you are interested only in changes in a small part of your composition, limit which portion of the composition is
rendered to the screen during previews. See “To change the region of interest” on page 118.
Deselect Show Cache Indicators.
Deselect Show Cache Indicators in the Timeline Options menu to prevent After Effects from displaying green and
blue bars in the time ruler to indicate cached frames.
Deselect Show Rendering Progress In Info Panel & Flowchart.
Deselect this Display preference to prevent the details of each render operation for each frame from being written to
the screen.
Hide Current Render Details in the Render Queue panel.
To hide these details, click the triangle beside Current Render Details in the Render Queue panel.
Press the Caps Lock key to prevent After Effects from updating Footage, Layer, or Composition panels.
When you make a change that would otherwise appear in a panel, After Effects adds a red outline to the panel. After
Effects continues to update panel controls such as motion paths, anchor points, and mask outlines as you move them.
To resume panel updates and display all changes, press Caps Lock again.
Lower a layer’s display quality to Draft or Wireframe.
See “To change the layer image quality” on page 168.
Select Draft 3D mode in the Timeline panel menu.
Draft 3D mode disables all lights and shadows that fall on 3D layers. It also disables the camera’s depth-of-field blur.
Deselect Live Update in the Timeline panel menu.
This prevents After Effects from updating compositions dynamically.
