infinite zoom

[asianeye]

Hi guys

I try to create a infinite zoom effect just like the Opening Scene of 'Limitless'

Any one know how to write a expression to help axis or camera move in constant speed for the entire sequence?

or any simple way to do it?

Many thanks

Just set two keyframes to establish the speed you want (whether it's the camera or an axis) and then set the extrapolation to Linear.

It is not that simple since it need to travel a really far distance.. It is just getting faster toward the end even the Interpolation and extrapolation is Linear.
