Hi all,

I've been attempting to solve this problem over a couple of projects now and have always had to resort to a temporary patch. I've finally caved and am going to see if the AE List can help.

I've filmed some tracking markers which I've tracked in AE and generated keyframes to apply to my camera in order to simulate a realistic camera shake. That's all fine and works but what I'd like to do is to be able to scale these values, probably via an expression control effect on a null or something like that - the reason I want to be able to scale is to a/. tone down or up the overall effect and b/. scale the effect over time so that shake increases over time for example. 

The obvious (to me anyhow) approach would be to use an expression that divides the position value by 2 (for example) in order to reduce the amount of shake. That certainly halves the overall range of the position but it also shifts the camera's position to a new location as opposed to leaving the camera at the specified location but to wiggle it within the range specified by the tracked motion.

Using parenting works but only if I don't scale the effect. I get the sense that Dan Ebberts' article here is related but unfortunately I've not been able to make the leap.

Thanks for any kind of help on this.
