Syntax:

byframe = <float> ;

Option:

-b <by>

Range:

Unbounded.

Default:

1

Purpose:

This determines the frame skip factor.

Comments:

This is used in conjunction with startframe and endframe to determine the tem-poral extent of the rendering. If the skip factor is set to 1, every frame is rendered. If it is set to 2, every second frame is rendered. If it is set to -1, frames will be ren-dered in re-verse order.

Example:

byframe = -0.5;
