Render is a program for creating composite BMP image sequences. These images can be animated and superimposed in various ways, as specified in a configuration file.

Mixer is a program for mixing film soundtracks. It accepts input files in WAV format and outputs a mixed soundtrack in WAV format. Each input file can be placed on one or more stereo audio channels.
The maximum number of channels is a compile-time parameter.
