wiggle expression

[Missdivagirl]

Also, is there a way to control the expression as a sort of a time remap… for instance, i want it to wiggle at one speed but at a certain point I would like the wiggle to increase tremendously and then go back to what it was before.

Thank you!!!

Cheers!

One way is tying either Amplitude or Frequency of the wiggle to a slider, then keyframing the slider. setting the slider to a number (7) gives you that Amplitude, then 0 down the line kills the wiggle (gradually), if you want the wiggle to stop abruptly use hold keyframes.

In case you don’t know how:

wiggle (7,30)

highlight (select) the 7, then pickwhip to a slider stopwatch(Effect>Expression Controls>Slider Control) and you have an expression like this:

wiggle (effect(“Slider Control”)(“Slider”),30)

Setting keyframes with the slider now puts you in complete control.

If you want all layers to wiggle the same, in unison, Put the Slider on a Null (Master) and pickwhip to that.

Note: You don’t have to do all the expression stuff manually for each letter layer, just set up one, Highlight the property with the expression and Edit>Copy Expression Only, then select the new layers you want the expression applied to and Paste. Pretty quick.

You could also do a slider for the Frequenct (30) but if you like the 30 I’d leave it.

If you think you’ll use the setup again, Save it as an Animation Preset.

When we first learn about expressions, we use the pickwhip to connect one property with another and create an expression. (check the help) This pickwhip is useful in other situations — this being one of them.

1) apply effect>expression controls>slider control to the layer. It can be applied to any layer, even a null, actually.
2) make this control visible in the timeline. Try selecting the layer then hitting the E key.
3) rename the effect “amp slider”.
4) Make sure your wiggle expression is visible in the timeline. Try hitting EE. You may have to hit U or UU, depending on what appears and disappears.
5) highlight the word “amp” in the wiggle expression.
6) drag the pickwhip from that expression to the “amp slider” effect in the timeline.

Now the amplitude of the wiggle matches the value of the slider. Animate the value of the slider (using keyframes as usual) to change the amplitude (amount) of wiggle.

You can do the same with the wiggle’s frequency and another slider named “freq slider”, for example.

Hope that helps …

If you setup a slider to control the Amplitude, keyframes from 0 to 7 to Tremendous will make the wiggle so.

Thank you so much for all the help!!! It is greatly appreciated and surprisingly all makes sense to me, which is great… yea for me!

Thank you again for your time!!!

this is not working for me…

when I put keyframes from 0 to 1, between this keyframes it moves very quickly and when it arrives to 1 it moves in the correct frequency.

It is somehow reading the decimals as more than 1.

What can I do?
