Waveform Effect

[Set Hallstrom <sakrecoer gmail com>]

Dear all,

I have a slightly off-topic question:

I've been searching like crazy for information about the waveform effect
available in cheese. I would like to use this effect in a video editor
such as kdenlive or cinelerra.

Is there any chance that someone on this list could point me to some
information about this filter?

Thankful for your time and answers,

Set H.
