This is a raw capture strait out of my quartz composer project. Actually ended up capturing it with my Edirol P10 to motion jpeg codec because I was having performance issues capturing with software based capturing (iShowU).
I then exported to H264 to get the size below 500MB for vimeo. So quality isn't that great but it will give you an idea of what this quartz composition is capable of. I will def. be using this patch in my live performances.
To create this effect in quartz composer I right clicked a movie patch and set the timebase to external then connected my audio output (normalized value) to some math patch to multiply it by my movie's actual duration, then connected this resulting value to the newly created movie time input on the movie patch..
Let me know if you have any Questions.
