Anyone have any tips on animating to audio like if say a audio clip is 9 seconds how many frames should my animation be ? ect.. thanks

Usually animation is 30 frames per second, so in your case you'd need 270 frames for 90 seconds. I'm not an animation expert, and I know there's times that people choose 24 frames instead of 30, but I can't remember the reason why so I'd go with 30 fps to be on the safe side.

Generally, I think 15fps is adequate for animation. That's what I use and have had good results.

thanks guys

It depends on whether you need to put the animation to a video tape or on the web. For tape, you need 30 FPS. For use on the web, you can get by with much lower rates; even 8 FPS is good enough for most purposes.

You do need 30fps for tape, but you can still do your anim at 15fps and have your video editing program change it to 30fps. I've done this many times and it works flawless. Looks the same on video at 30fps as on the computer at 15fps.
