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.
