To get control over the wiggling I like to link each wiggle parameter to a keyframed expression slider control (one for amplitude and one for frequency). P.A.T.

Looking for a way to wiggle position along a path. Thanks. P.A.T.

Try this: freq = 1; t = key(numKeys).time; w = transform.rotation.wiggle(freq,100)-transform.rotation; newT = linear(w,-100,100,0,t); valueAtTime(newT) Dan

To be more precise, I exported the compositing project file (with the camera), and its the 3d layers added in AE that blur that way when turning MB on. P.A.T.
Turning only one effect on

Hello, I have 3 different tint effects applied to 1 layer and I'd ideally have to make sure that when you turn one on the others turn off automatically. Is that possible Thanks P.A.T.

You might find videocopilot's evolution package interesting for that purpose, if you don't absolutely have to use your original swirls. http: www.videocopilot.net products evolution
