.TP
.B \-a, \-\-render-anim 
Render frames from start to end (inclusive)

.TP
.B \-S, \-\-scene <name>
Set the active scene <name> for rendering

.TP
.B \-f, \-\-render-frame <frame>
Render frame <frame> and save it

.TP
.B \-s, \-\-frame-start <frame>
Set start to frame <frame> (use before the \-a argument)

.TP
.B \-e, \-\-frame-end <frame>
Set end to frame <frame> (use before the \-a argument)

.TP
.B \-j, \-\-frame-jump <frames>
Set number of frames to step forward after each rendered frame

.TP
.B \-o, --render-output <path>
Set the render path and file name.
.IP
Use // at the start of the path to render relative to the blend file.
.IP
The # characters are replaced by the frame number, and used to define zero padding.
.IP
    ani_##_test.png becomes ani_01_test.png
    test-######.png becomes test-000001.png
    When the filename does not contain #, The suffix #### is added to the filename
.IP
The frame number will be added at the end of the filename.
    eg: blender -b foobar.blend -o //render_ -F PNG -x 1 -a
    //render_ becomes //render_####, writing frames as //render_0001.png//
