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 cer tain controller t ypes, you can force
constant velocity from one component k ey to
the next using Constant Velocity.
If you are creating Path animation, you can force
constant velocity by placing a
Normalize Spline
modifier (page 1–739)
on the spline used as a path.
