The Radial blur effect wiil definately work for you, just follow the links in the previous post (if your even still visiting this sight). Also, to help you with your audio problem, I run AE on a sony Vaio dual prossessor and also have this problem occasionally. My best advice would be to open the audio file in Premiere if you have it (or any other program that will let you view the waveform, ie. Garage Band) and get familiar with the waveform of the file. Then open your waveform view in AE of your audio file and do your animating based on the waveform. If your trying to do somethind like animate to the beat of the music, this shouldn’t be too difficult with the waveform view. Post back if this helps just to let me know (and why don’t you give Creative Cow one more try, maybe subscribe to the podcast or something).
Glad to help if I did,
Andy
