Frame caching is controlled by Edit menu commands. The appearance of cached frames is

set in the Preferences Appearance tab. The location, size and type of cache are set

Preferences Preview tab. For more information, see “Preferences Window” on page 158.

The following Frame Cache commands appear in the Edit menu:

Select Cache Video Frames and Cache Rendered Frames in most situations, as they almost

always reduce preview times. You can try disabling one or both options if you think the

caching process is slowing down your workflow.

Rendering Effects

Render an Avid FX effect as you would render any effect within the Avid editing

application. However, you should note the following when rendering effects:

• Turn on the visibility of all the tracks and filters you want to appear in the effect before

rendering, otherwise the effect will not appear in the rendered output.

• Restore motion blur visibility before rendering or motion blur is not applied in the

rendered effects. The Global Motion Blur button affects all compositions in the Render

Queue. See “Timeline Display Buttons” on page 80.

• Check the Local Projects tab in the Preferences window to ensure that you selected the

correct render settings for the effect—see “Preferences Window” on page 158.

• If you are rendering effects that include edging, an alpha channel or DVE moves, make

sure to select Better Quality Field Rendering.

• Changes to the Preview and Composite windows do not affect the rendered output.

Therefore, changing resolution, quality, or scale, displaying on-screen controls, grids,

and other marks, or viewing only selected channels does not affect the rendered output.

• The Avid FX timeline renders from bottom to up.
