I have a video file that I'd like to create a new video with the original video with a waterfall spectrogram right below it.

http://www.youtube.com/watch?feature=player_detailpage&v=5Czo_CYd94s#t=131s

Sorta like the video above, where the frequency domain is on the horizontal axis, time is on the vertical axis, and color is the amplitude.

Now, I'm thinking I may need to strip the audio from the video, generate a the waterfall spectrogram separately and edit the video to include it. But i'm not sure where to start.
