Internal video generator.
The video generator will be activated
in two different ways: If selected as a
fallback option the generator will
generate the selected pattern when
the other input(s) are missing, and
then use the video settings from the

also be selected as the main input in
cho 1, in which case its own video
settings will also be used. cbar
denotes colorbar, while mcbar
