There are a ton of applications for wiggle and with these 3 tips you can use it even more effectively.
If you aren't super familiar with the wiggle expression, it's a way for you to have After Effects inject some randomness into your property values, so that without having to create a single keyframe, you can make things more lively. You could apply wiggle to the position and rotation of a layer if you wanted to add some fake camera shake, or wiggle the brightness of a lens flare to make it flicker and look less static and boring, etc. There are a ton of applications for wiggle and with these 3 tips you can use it even more effectively.
Animating - you can actually animate the two main properties of a wiggle to gain more control over it: The frequency & the amount (it's technically called the amplitude) can be animated by adding Slider Controls to your layer (Effect -- Expression Controls -- Slider Control). Then when adding your wiggle, instead of writing a frequency or amount value, you can use the pickwhip next to the expression box to link to one of your slider's values instead! Now by animating the slider value, you're animating the wiggle's properties!
Per Axis - for the times you only want to wiggle a position on a single axis, or wiggle a scale uniformly: You can actually reference the property value itself using value and you can even specify which dimension of a value you're referring to using square brackets. If I wanted only the X value of the position property I would write 0 between square brackets next , for the Y value it would be value[1] and I'm sure you could guess what it would be for the Z Value. Knowing this, we can wiggle on the Y axis alone by having the position property's X Value refer to it's own X Value "value[0]" and making the Y Value refer to a wiggle's Y value "wiggle(1,50)[1]". So The full expression to have wiggle only affect the Y axis would be [ value[0], wiggle(1,50)[1] ]
Smoothing - sometimes wiggles can be a little too twitchy, we can fix that: Using the smooth expression you can smooth out keyframe values, so the first thing to do would be converting your wiggle into keyframes! You can do that by right clicking the property you're wiggling and choosing Keyframe Assistant -- Convert Expression to Keyframes. The two important properties of the smooth expression are width - the range in time to smooth values over, and the samples - how many sample values to use within the range when calculating the smoothing.

Great work !
your channel is really underrated.
and there is even more tips I wanna share :
1- wiggle function will not generate the same values each time you use it and sometimes it could be a problem, to solve this you can use seedRandom function before your wiggle expression :
seedRandom(x,true)
;
wiggle(2, 50);
x=its the seed and so u can put any number here , so if u put the same seed number in two wiggle functions that have the same freq and amp they will generate the same values.
2- you can add phase to your wiggle function which some times could be helpful :
phase =effect("your slider control effect name")("Slider")*thisComp.frameDuration;
wiggle(2, 50, 1, .5,time + phase);
the 3rd and 4th values are default values you don't have to change them.
Thanks for including these! I believe the wiggle seed is auto-generated depending on the layer order, property and time in the sequence so setting the seed with seedRandom is a great way to keep your wiggles consistent! It's also useful even if you're not trying to match wiggles across multiple layers/properties because as you rearrange or add layers to your comp, your layer's index might change which will also change the wiggle's seed, so just to have more control over your wiggle and not have it change up on you, setting the seed can be helpful!
Thank you so so much both for these great, amazing tips and explanations! Had no idea I can control the wiggle with random seed!
I have a question, what does the "phase" tip helps do exactly? I'm still a bit fresh with expressions so I couldn't figure out what it does just by reading the code. Could you please elaborate more?
Does it serve as a delay to the wiggle? Like if two shapes have the same wiggle seeds but you want to delay them from each other a bit you use time+phase?
Thank you so much once again 🙏
@@m.a8735 Yes, exactly !
phase is like adding or subtracting from time value :)
And Damn again! This is EXACTLY what I have been trying to figure out how to do! Thank's so much!
Wow, I've been using wiggle for years but it never crossed my mind that I could link it to a slider control. Thank you!
youre story telling abilities are crazy good.
Excellent structuring, quality, and information. Earned my sub and can't wait to see this channel grow!
Most informative and productive 8 min and 43 seconds of my life - thank you!!
The first tip has helped me a lot. Thanks for that.
killing it with these tutorials!
Love your work! Thanks for the great advice in such a high quality, easy to follow format! 10/10
Thanks so much! I’m glad you like it!
I saw the intro on Reddit, i liked it and now I’m here.
Glad to have you here Cristofor!
A most excellent example of keyframe assistant, graph editor, etc. Thank you! (I subbed).
Legitimately fantastic work, these are hands down some of the best after effects tutorials I've ever seen. I'm including Andrew Kramer in that.
just might be the best tutorial i’ve ever seen! thank you so much!!
Wow, this is amazing! So very well explained too.
my fav expression of all time on after effects!
Great content, thanks for the tips, I learnt a lot from your last video, I hope to use them soon!
Thanks Ignacio! glad to hear it!!
What a great Video. Found exactly what I was looking for. And I really like your presentation style! Keep it up, bro!

OMG! Thank you very much for sharing this, it helps me a lot😭😭😭😭
To say this is an excellent video tutorial would be an understatement. I make templates that I sell and I'm always looking to learn different ways to use Expression Controls. I will definatley be checking out all your video content on your channel. Thanks again!
OMG all those easter eggs that I find in all your videos.
I've been using After Effects recently and needed a good refresh on some basics.
I just found better, a new private teacher.
haha glad someone spotted them!
easter eggs? child..
@@jamskof lmao newie :)
you just saved my life, thank you.
Thanks!
This was very insightful. Thanks alot!

Really nice video my dude! Appreciate the effort & the jokes :)
Great teaching, funny too. Subscribed!
Thanks man
Holy shit, you are a lifesaver
Awesome Tutorial!
Sick video! how did you do the reveal effect on logo and text at the beginning?
THANK YOUUUUU
Damn great, thanks a lot!
2:43 that little talk anim added sauce on top! could you tell me which effects did u used?
you are the man
Hi! excellent video by the way, but I have a problem, when I put keyframe to slowly increase frequency and amount, I noticed that in the transition time between one value to another, the wiggle effect going crazy and then stabilize when the keyframe is passed, how can I resolve?
Great tutorial thank you, is there any way to create a wiggle over a large space without it going outside the composition ? Thank you
Don’t forget Wiggle Loop is very Important
Is there a non-destructive way to smooth out the wiggle? Without converting to keyframes?
I’ve definitely looked for a way before but sadly I don’t think there is
how to animate this map with graph ?
Cool. But what about next wiggle parameters? Actually there are 5 params.. Can you make a new video with explanation of these please?
It's art... text reveal/transition, what have you, is a thing of beauty... I'd watch that tut... just saying. Don't tell anyone, I downloaded this video... shshshshhshhshshshsh (ya no idea how u spell that)
hey, howd you do those transitions 0:08? they look really cool
youre fantastic
@3:54 you mention key-framing using sliders. However, when I've tried this over the years, it goes haywire between those keyframes. There's no easing like you showed. I've tried this on the position as well as the rotation and it's the same.
Same here. In fact the latest After Effects doesn't seem to allow for slider "keyframes" for wiggle.
It's a huge issue since I need to pause the wiggle and continue but haven't found a reasonable solution.
Homie went and put so much quality into the tut. Made me feel like "okay this is going to be some good quality tips" n low n behold it was. Pleasure to watch and keep up the great work! Also check me out for less cool tuts. Cheers mate!
HOW DID YOU DO THE "GROS" MOUTH THING???? 😱😱😱😱😱😱😱
for some reason my clip won't wiggle when i click on the ram preview, but it wiggles when it's been rendered. i used to be able to see it in the preview... any idea what could be wrong? 😓
nvm, i had it set to just front camera instead of active camera lmao
Hi, thank you for your tutorial. I am trying to write the code so while using wiggle the circle doesn't go out of the comp but covering most of the area. I take the conditions like the x and y must be between 0+radius and width/height-radius but it gets irresponsive or with error. Can you guide me or suggest where I can find the solution. I have two circles so the idea is to move them around randomly but if they get close, like length
Hey, you can try something like this:
w = wiggle(5, 1000);
padding = 200;
xClamp = linear(w[0], -1000, 1000, 0 + padding, 1920 - padding);
yClamp = linear(w[1], -1000, 1000, 0 + padding, 1080 - padding);
[xClamp, yClamp]
this assumes your comp is 1920x1080, you can adjust the padding to control how close it's allowed to get to the edges. Also if you change the wiggle amount, just make sure you also update the xClamp and yClamp expressions!
edit: if you want more info/want to brush up on the linear() function, check out my video on interpolating expressions :)
@@AcademyOfEdits Thank you very much. You literally got me out of the box with the padding. You're great!
I wish there was a way to smooth the expression without having to commit keyframes.
Thank you very much for explanation,

Questions :
- for smoothness, why don't you use 3rd and/or 4th parameters of wiggle expression ? = wiggle(freq, amp, octaves = 1, amp_mult = .5, t = time)
the amplitude multiplicator isn't the same as smoothness ?
- keyframe the AMPLITUDE is glitchy when decreasing it… it's better to decrease the amplitude. -> Because it's like time travelling fast or slow. Decreasing it when you where high amplitude (fast) means litterally going backward where should be, counting the value from the begining. Am i clear ? give it a try, you'll see.
