Hi All,
I have set up a camera attached to a null to go through a series of layers in z space. It works fine, but i need the speed of the layers going by to increase over time. It works to a certain degree by precomposing my setup comp and using time-remap by tweaking the velocitty curves, but it's still not quite doing what effect I need. I know this might be a simple expression, but for some reason, I can't get my head around it.
Any help would be greatly appreciated, so I can meet my deadline!
Thanks.

Exponential increase in speed of a layer/camera
Not sure if this would work, but maybe you could AE's exponential scale, and tie your camera move to the scale via expressions?
Just an idea

Try putting this on your layers rather than precomposing them:
accellMultiplier=5;
x=position[0];
y=position[1];
z=position[2]+(time-(Math.exp(time*accellMultiplier)));
[x,y,z]
This expression causes your layer to move backwards in z space exponentially over time. accellMultiplier lets you affect when the curve reaches "terminal velocity." If you want to reverse the direction of the push, change the '+' before the parentheses in the z definition to a '-'.
