Default Bullet Time !

I just saw the Bullet time tutorial - excellent by the way - and now I am wondering how to do the Bullet Time effect (camera motion) ?

Does anybody done this before ? if so, how did you do it ?

it could probably be done easiest in an editing program, such as After Effects.

yeap .. .you would need quite a lot of fps (frames per second) how about animating your motion in ehh ... 120 fps or even 240?

I'll add a video tutorial to show how to do this in Maya soon

But for now, ONE way to do it in Maya is to:

1. Create your animation, and render it out at 30 FPS to see how your action looks at normal speed. (good habbit)
2. Now, choose a range of frames that you want to use for your BulletTime effect, and animate a SEPARATE camera (your effect cam), where you want it.
3. Crank the FPS up to about 150FPS, or higher if you want.
4. Render out your chosen frames through your "Bullet" cam.

Some key things to remember are:
-Check that your motion blur is not set too high, or you will loose the detail in your BT shot.
-Play around with various frame rates
-Adjust your animation curves for smoother animation, rather than jerky motion
-Use of a compositor with a TIME-STRETCH, or INTERPOLATION feature of some type will give you the BEST results during the transition from 30FPS, to your Bullet-time sequence of frames

There are MANY ways to do this effect, and I've found that this is the fastest way for ME

Good luck!
