Adobe AFTER EFFECTS CS3 PROFESSIONAL User Manual page 623

This example command tells After Effects to render frames 1 through 10 of Composition_1 in project_1.aep to a
numbered sequence of Photoshop files using a multi-machine render:
aerender -project c:\projects\project_1.aep -comp "Composition_1" -s 1 -e 10
-RStemplate "Multi-Machine Settings" -OMtemplate "Multi-Machine Sequence"
-output c:\output\project_1\frames[####].psd
To render just Composition_1 to a specified file, enter this command:
aerender -project c:\projects\project_1.aep -comp "Composition_1" -output c
:\output\project_1\project_1.avi
To render everything in the render queue with current settings in the project file, enter this command:
aerender -project c:\projects\project_1.aep

Description
Print usage message.
Display the version number of aerender to the console. Does not render.
specifies the type of messages reported:
verbose_flag
: Reports only fatal and problem errors.
ERRORS
ERRORS_AND_PROGRESS : (default) Reports errors and progress of
rendering.
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.
specifies the maximum percentage of memory
image_cache_percent
used to cache already rendered images and footage.
specifies the total percentage of memory that can be used by After Effects.
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.
is a file path or URI specifying a project file to open. If this
project_path
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.
specifies a composition to be rendered. If the composition is in
comp_name
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 argu-
ment is not used, aerender renders the entire render queue; in this case, only
the –project , –log , –output
ments are used, and all other arguments are ignored.
is the first frame to render. If this argument is not used,
start_frame
aerender uses the start frame in the file.
is the last frame to render. If this argument is not provided,
end_frame
aerender uses the end frame in the file.
