USING AFTER EFFECTS CS4

Rendering and exporting

Last updated 12/21/2009

Argument

Description

–help

Print usage message.

–version

Display the version number of aerender to the console. Does not render.

–v verbose_flag

verbose_flag

specifies the kind of messages reported:

ERRORS

: Reports only fatal and problem errors.

ERRORS_AND_PROGRESS

: (default) Reports errors and progress of

rendering.

–reuse

Reuse the currently running instance of After Effects (if found) to perform the
render. When an already running instance is used, aerender saves
preferences to disk when rendering has completed, but does not quit After
Effects. If this argument is not used, aerender starts a new instance of After
Effects, even if one is already running. It quits that instance when rendering
has completed, and does not save preferences.

–mem_usage

image_cache_percentmax_mem_

percent

image_cache_percent

specifies the maximum percentage of memory

used to cache already rendered images and footage.

max_mem_percent

specifies the total percentage of memory that After Effects can use. For both
values, if installed RAM is less than a given amount (n gigabytes), the value is
a percentage of the installed RAM, and is otherwise a percentage of n. The
value of n is 2 GB for 32-bit Windows, 4 GB for 64-bit Windows, and 3.5 GB for
Mac OS.

–project project_path

project_path

is a file path or URI specifying a project file to open. If this

argument is not used, aerender works with the currently open project. If no
project is specified and no project is open, the result is an error.

–comp comp_name

comp_name

specifies a composition to render. If the composition is in the

render queue already, then the first instance of that composition in the
render queue is rendered. If the composition is in the project but not in the
render queue, then it is added to the render queue and rendered. If this
argument is not used, aerender renders the entire render queue; in this case,
only the

–project

,

–log

,

–output

,

–v

,

–mem_usage

, and

–close

arguments are used, and all other arguments are ignored.

–s start_frame

start_frame

is the first frame to render. If this argument is not used,

aerender uses the start frame in the file.

–e end_frame

end_frame

is the last frame to render. If this argument is not provided,

aerender uses the end frame in the file.

–i increment

increment

is the number of frames to advance before rendering a new

frame. A value of 1 (the default) causes normal rendering of all frames. Higher
values render a frame and use it

increment

times in output, and then skip

ahead

increment

frames to begin the cycle again. Higher values result in

faster renders but choppier motion.

–OMtemplate

output_module_template

output_module_template

is the name of a template to apply to the

output module. If the template does not exist, using this argument causes an
error. If this argument is not used, aerender uses the template already
defined for the output module.

–RStemplate

render_sett

ings_template

render_settings_template

is the name of a template to apply to the

render item. If the template does not exist, using this argument causes an
error. If this argument is not used, aerender uses the render template already
defined for the item.

–output output_path

output_path

is a file path or URI specifying the destination for the final

output file. If this argument is not used, aerender uses the path defined in the
project file.
