Using timeline to manually animate curvy position.

[gtpdz]

This is a great asset for creating spline and animate object along them, however when using curvy combined with Unity Timeline and Cinemachine, when the object position is updated via timeline key frame along the spline, the cinemachine camera is never smooth when the timeline is played. 

Suspecting manually update the object's position via timeline has a bit of delay. Does anyone find a work around? Thanks in advance.
