The Shake Command-Line Manual

-motion

Sets the motion blur quality. In the command line, you must enable
override (set it to 1). When executing a script, you either multiply
what is saved as the global motion blur value (override = 0), or
override it (override = 1).

-node

Only executes that node. For use with -exec.

-nocache

Disables the call to the cache, forcing complete recomputation of
each element.

-noexec

Does nothing except compile the script to see if there are errors.

-pixelscale [ratio]

Sets the pixelscale and ratio. Not frequently used in the command
line. See Chapter 4, “

Using Proxies

,” on page 137.

-proxyscale [ratio]

Sets the proxyscale and ratio. Does a low-resolution test render of
your commands. You can specify two numbers—the scale and
ratio, or p1/p2/p3 which uses the preset proxies. See Chapter 4,

Using Proxies

,” on page 137.

-renderproxies [p1] [p2] [p3]

Renders FileIn nodes already saved into a script as the preset
proxies. If used without arguments, renders what is saved in the
script, otherwise you can specify which subproxies you want, p1,
p2 , and/or p3. Usually used with -createdirs.

-sequential

Sequentially executes functions. For use with -exec. When you have
multiple FileOut nodes, it may be more efficient to render them one
at a time with this flag, rather than simultaneously.

-shutter [offset] Sets motion blur shutter controls.

Quality Controls

Description

-fast [quality]

When no argument is given (just -fast), anti-aliasing is disabled to
speed the render. -fast 1 sets quality to 0 (low), while -fast 0 sets
quality to 1 (high).

Masking Controls

Description

-evenonly

Example:

shake bg.iff -rotate 45 -evenonly
bg.iff

Only executes the previous commands on the even fields of the
image, and mixes it back in with the image you supply.

-isolate

Example:

shake bg.iff -blur 50 -isolate bg.iff
a

Only executes the previous commands on the channels you
specify, and mixes it back in with the image you supply.

-mask [channel]
[percent] [invert]

Example:

shake bg.iff -blur 50 -mask
truck.iff

Masks off the previous commands you specify, with the mask
coming from the image. You can specify the channel and
percentage, or invert the mask.
