music visualization

[yoursnayak]

Hello,
I need a 1280x1280 30fps video of music visualization for a 4 minute
song. I tried using screen capture software to capture video of the
iTunes visualizer, but at that high of resolution and 30fps, it just
can't keep up. I don't necessarily need to use iTunes visualizer. If
there is some visualization software that will output a video file for
me, that would be great. Anybody have any ideas on how to do this?

OK I have tried and tested it.I used Media Monkey for this purpose. You need registered version of fraps because trial version only records 30 sec video. All you have to do is just play a song start visualization and then make it full screen for your convenience and then press F9 and after 4 min again press F9 and voila your video is stored in fraps folder. But you have to lower the bitrate of that file because file size will be sky high and you are done.
