Rendering and exporting

Proxy Use Determines whether to use proxies when rendering. Current Settings uses the settings for each footage
item. (See “ Placeholders and proxies ” on page 83.)
Effects Current Settings (default) uses the current settings for Effect switches . All On renders all applied effects.
All Off renders no effects.
Solo Switches Current Settings (default) uses the current settings for Solo switches for each layer. All Off renders
as if all Solo switches are off. (See “ Solo a layer ” on page 156.)
Guide Layers Current Settings renders guide layers in the top-level composition. All Off (the default setting) does not
render guide layers. Guide layers in nested compositions are never rendered. (See “ Guide layers ” on page 168.)
Color Depth Current Settings (default) uses the project bit depth. (See “ Color depth and high dynamic range color ”
on page 274.)
Frame Blending On For Checked Layers renders frame blending only for layers with the Frame Blending switch
set, regardless of the Enable Frame Blending setting for the composition. (See “ Frame blending ” on page 253.)
Field Render Determines the field-rendering technique used for the rendered composition. Choose Off if you are
rendering for film or for display on a computer screen. (See “ Separate video fields and determine field order ” on
page 93.)
3:2 Pulldown Specifies the phase of 3:2 pulldown. (See “ Introduce 3:2 pulldown ” on page 736.)
Motion Blur Current Settings uses the current settings for the Motion Blur layer switch and the Enable Motion Blur
composition switch. On For Checked Layers renders motion blur only for layers with the Motion Blur layer switch set,
regardless of the Enable Motion Blur setting for the composition. Off For All Layers renders all layers without motion
blur regardless of the layer switch and composition switch settings. (See “
Motion blur ” on page 227.)
Time Span How much of the composition to render. To render the entire composition, choose Length Of Comp. To
render only the part of the composition indicated by the work-area markers, choose Work Area Only. To render a
custom time span, choose Custom. (See “
Work area ” on page 201.)
Frame Rate The sampling frame rate to use when rendering the movie. Select Use Comp’s Frame Rate to use the frame
rate specified in the Composition Settings dialog box, or select Use This Frame Rate to use a different frame rate. The
actual frame rate of the composition is unchanged. The frame rate of the final encoded movie is determined by the
output module settings. (See “
Frame rate ” on page 75.)
Use Storage Overflow Determines whether rendering continues when the first assigned storage volume overflows. If
this option isn’t selected, rendering pauses when the first assigned volume reaches capacity. (See “ Overflow volumes
and segment settings ” on page 731.)
Skip Existing Files Lets you rerender part of a sequence of files without wasting time on previously rendered frames.
When rendering a sequence of files, After Effects locates files that are part of the current sequence, identifies the
missing frames, and then renders only those frames, inserting them where they belong in the sequence. You can also
use this option to render an image sequence on multiple computers. (See “
Render a still-image sequence with multiple
computers ” on page 730.)
Note: The current image sequence must have the same name as the existing image sequence, and the starting frame
number, frame rate, and time span must be the same. You must render to the folder that contains the previously rendered
frames.
Shoaib Khan provides a video tutorial on the MaxAfter website that shows how to use the Skip Existing Files option to
avoid needing to rerender an entire movie when correcting a simple mistake in a rendered image sequence.
