The Key Info (Advanced) rollout or dialog lets you control velocity in three

ways:

■ You can specify the absolute velocity at a key using the In/Out fields.

■ You can average velocity over a time period using Normalize Time.

■ With certain controller types, you can force constant velocity from one

component key to the next using Constant Velocity.

If you are creating Path animation, you can force constant velocity by placing

a Normalize Spline modifier on page 1583 on the spline used as a path.
