Starting with mantra 9, most command-line options are overrides for properties. This means you can set these properties on the scene camera, and then override them on the command line if necessary.
Saving an IFD or RIB file
IFD is the scene description format produced by Houdini and consumed by mantra to produce a rendered image or animation sequence. The IFD file contains a complete description of the scene and how to render it.
RIB is the equivalent of IFD for RenderMan and RenderMan-compatible renderers.
You can set up a render output node to save a file instead of rendering an image directly. This gives you the flexibility of rendering at another time, from another machine, or on a render farm. See network rendering.

Mantra command line options
Specify a comma separated list of hosts to perform rendering. For example -H chili,cayenne.
Number of processes to render using network rendering (deprecated in favor of -j).
When network rendering, ensure that remote hosts will run at least this version of mantra.
Specify the number of threads (
Read the IFD from the file given instead of from stdin.
Indicates that the first argument after all options specifies the name of the IFD file to render (instead of the output image).
Send verbose output to the file given.
On Windows, you can use
Append verbose output to the file given.
Specifies a python filter program (see Python Filtering).
If the string contains
