How do I fix animation interpolation jerk ?

This post is in regards to a problem posted on Unity Japan's blog and is related to animation interpolation.

Reference : http://japan.unity3d.com/blog/?p=290

There is a sample Unity project at the bottom of the blog illustrating the problem, and 1 fix for it called an "AnimationLatch".

The project has a camera that animates around a block from 2 locations.

Basically the problem is that when the camera interpolates from location 1 to location 2 (or vice versa) there is a noticeable "jerk".

There is a slider control in the upper left corner of the screen that lets you control the speed.

(Slow it down to see the interpolation jerk better)

I am currently seeing this problem in a game project I am working on.

I wanted to ask: How do you fix this animation interpolation jerk problem ?

Is there is a better solution than the above mentioned "AnimationLatch" method.

Not sure if it matters but the art production team is using Maya to create the animations for our game.
