Expression for Wiggle only horizontal & uneven
Posted by Areful Eeslam on May 26, 2012 at 11:46 amHI, i was wondering what would be the expression for wiggling only horizontal perspective. Imagine a camera is panning or shaking left & right very fast to create a dramatic effect but not like earthquake and the velocity is uneven but smooth.
Hope someone can help.
Regards

May 26, 2012 at 6:18 pmHave you tried something like this:
amp = 15;
freq = 1;
w = wiggle(freq,amp);
[w[0],value[1],value[2]]Dan

May 26, 2012 at 6:58 pmSorry, I thought you were going to apply it to a camera or a 3D layer. Try it this way:
amp = 15;
freq = 1;
w = wiggle(freq,amp);
[w[0],value[1]]Dan

May 27, 2012 at 7:52 pmThanks for the reply once again. It’s works but it’s very slow, how do i increase the speed to make it very faster like earthquake but not exactly like earthquake if u know what i mean.

May 27, 2012 at 7:57 pmPlease dont bother i got by right by chaining the value.
amp = 40;
freq = 10;
w = wiggle(freq,amp);
[w[0],value[1]]works for me fine.
Thanks a lot for the help.

May 27, 2012 at 8:07 pmHello again, im stuck with another problem, how do i keyframe the expression values (to increase the value gradually), the expression slider is not working & im sure im doing something wrong. Will you help me out here.

May 27, 2012 at 8:52 pmKeyframing a slider for amplitude should work fine. Frequency is a different story altogether. Is that what you’re trying to do?
amp = effect(“Slider Control”)(“Slider”);
freq = 10;
w = wiggle(freq,amp);
[w[0],value[1]]Dan

May 28, 2012 at 10:18 amNo actually i did a silly mistake. I was suppose to pickwhip to slider in the value which is amp = slider, but i accidentally removed the (=) & getting error. It was a minor thing when i made it again from the scratch it worked. Anyways thanks for your help again Dan i really appreciate it.
