mpng writes a series of numbered movie frames to png files with the specified prefix. If the ray_trace_frames variable is non-zero, these frames will be ray-traced. This operation can take several hours for a long movie.
Be sure to disable cache_frames when issuing this operation on a long movie (>100 frames) to avoid running out of memory.
Usage
mpng prefix [, first [, last [, preserve [, modal [, mode [, quiet
[, width [, height ]]]]]]]]
Options "first" and "last" can be used to specify an inclusive interval over which to render frames. Thus, you can write a smart Python program that will automatically distribute rendering over a cluster of workstations. If these options are left at zero, then the entire movie will be rendered.
Arguments
- prefix = string: filename prefix for saved images -- output files will be numbered and end in ".png"
- first = integer: starting frame {default: 0 (first frame)}
- last = integer: last frame {default: 0 (last frame)}
