5 Best Expressions for After Effects
Vložit
- čas přidán 21. 07. 2024
- There's a lot of amazing features hidden in After Effects to those that aren't familiar with expressions. When I first heard about expressions, I was trying to create a cool effect that I knew existed in Final Cut Pro, but years later I can say expressions are way more useful than just making cool effects. Using the right expression, in the right workflow can drastically improve your results. Whether that's an ease on an animation or a huge timesaving duplicator. I know starting expressions can be daunting and the thought of coding animations can be tricky. As if After Effects wasn't already a lot to begin with. But don't worry because we're kicking off this intro to expressions by going over the most useful ones that are also easy to learn. If you're new to the program, or an expert that might want to brush up on your After Effect skills, you're going to want to stick around because we'll be showing you real examples of motion graphics and animation using expressions.
Remember to alt-click on the property you want to apply the expression to get the expression editor window.
Wiggle
Wiggle(frequency,amplitude);
LoopOut
loopOut("cycle");
Time Counter
time.toFixed(2);
Time Animator
time*150
Blink
Speed =10;
n = Math.sin(time*Speed);
if (n****=0) 0 else 100;
**** For the Blink expression you have to add a "less than sign" otherwise known as an angled bracket (which CZcams bans from this description for some reason..🤦🏾♂️) in between the "n" and "=" in the last line of code.
Index
index*360/10

As an added tip, for the wiggle expression, theres a way to be able to keyframe the frequency and amplitude values with sliders.
1. Create adjustment layer, name it whatever you want - i.e. "Wiggler"
2. In the Effects panel, look up "Slider" and drop two of those onto the adjustment layer. Name one "frequency" and one "amplitude" or "Amount".
3. Open the expression editor for the element you want to wiggle, i.e., "Shape". Type in "wiggle(" and then click the pick whip tool in the expression editor for position, and drag it onto the "Frequency" slider in the adjustment layer. After Effects will complete the code for you.
4. ADD A COMMA
5. After the comma, repeat the pick whip for the second variable, dragging the whip to the "Amount" slider.
6. CLOSE THE PARENTHESES
7. Now, instead of editing the parameters in the expression editor, just use the sliders and keyframes made available by the adjustment layer. Sounds more complicated than it is, and adds a lot more control!

Your welcome
Thanks man
I'll thank you now, don't tell me what to do
Thanks Mr. Bluebomb
you're** as in you are. Thanks for the links!
black mixture always poppin out the good vids 👏 keep it goin
Index just became my absolute favourite expression. That’s a huge time-saver for sure!
This. Is. Great. Really need to jump onto expressions and this is a great way to start. Love the content you have been putting out.
Thanks Tom! 👍🏽
Thank you very much for that masterful and brief explanation about the expressions. Congratulations with all my heart.
this is an awesome tutorial - thank you for making it available :D love your style n vibe and brilliantly explained info. Thanks again!
Glad to help!!! Thanks so much🥰
This is great! I would also recommend the bounce back and overshoot expressions from Dan Ebberts, avoid animating bounces ever again
Awesome thank you 👍🏻
This is awesome. Thanks
I know these are older videos but its so relevant to a project I'm taking on at work. Thanks for sharing your knowledge.
Glad to hear this helped 🦊
Thank you so much for a properly explained video.
Is it possible to create a looping time animator by stacking the time animator expression and loopOut expression?
Uuum, I think the spacing when keying in your code helps with the end result, the Expressions actually work!
i would definitely include the if / else expression... but the index is maybe one of the most powerful. Cool List dude :)
Thanks so much for the dope videos dude
You bet! Thanks for the support!
amazing content dude, keep up
Appreciate it!
Killer content 👍
Thank you!! :-)
You are always awesome bro
You're always awesome too 👍🏽
@@BlackMixture thanks sir
thanks
Thanks I'm a beginner, this helped a lot. I did some parts differently but still worked out~! ty
So happy to help! Best of luck 🙏
Well thanks for that homie
how does the code look with the less than sign?
Tnx
2:00 GODBLESS, I knew I wasn't the only one who does that!
how to make your opening video?(high tempo text animation)
Brilliant don't forget your F9
Could you please make a tutorial on an enchanted forest like the one from maleficent? I’ve NEVER seen anyone make anything like that before. You can find the scene it’s called “Aurora meets Maleficent”
Great suggestion! I'll check it out 👍🏽
Black Mixture Thank you!
is there a keyboard shortcut to start typing
Vids and vibes!
I get the following error message when I type in the BLINK EXPRESSION: (SyntaxError: Unexpected Token Else). Can someone help me understand what that means or what I should do?
use the "extended" version of the if/else script, i.e. put the statements in curly braces {LIKE THIS} - here is a detailed explanation how to do it: motionscript.com/mastering-expressions/language-beginning-4.html
according to adobe forums, the short version without the {} does not work anymore for AE since cc2019 because of the way java script is implemented.
Hey! can you make a tutorial on how you made your intro.
Yes, soon!!!
your Blink snippet syntax seems off?
I could only get it to work by adding a semicolon to break up the if/else statement.
#####Blink####
Speed = 10;
n = Math.sin(time*Speed);
if (n
index and blink could save me a ton of time!

I died at the ravers part
lol i came a couple months ago to this channel and it was at 2k subs, now its 39.9 K already!!!!!!! WOW
Omg you're right! I'm like freaking out that we've grown that much that fast. Glad to have had you watching since back then! It's heartwarming to meet the day 1s 😁👍🏽
anyone know where I can get that animated power rangers dancing meme at?
Question
My favourite expression is OMG everytime I use FX Console.
Lol that's a good one 😅 mine too
Think i gotta go back to square one, #motiongraphicsfreshman
#First comment life
Cool effect!
Looks like Adobe changed its scripting a little recently but I found the updated code that works in AE22...👍
speed=10;
n=Math.sin(time*speed);
if(n
Yo thanks David! On behalf of everyone, I sincerely thank you for finding the updated code and posting it here 😁👍🏾
Supeeeerrrrrrr

I can't believe that there is a simpler way to do a loop, f*ck, all the time I've lost in these years man...
5:51 #BLVCKMXTR_365 i love that edit. where can i find the original??
Very nice, well done! … BTW: my Firefox warns me that your website is a malicious thing (Potential Security Risk) … looks like the ssl security certifictae has expired … this makes most users close that tab and never come back … so it's better to fix it … it's no big deal … google it! cheers!
Somebody got a new haircut.......
Im talking about code? Ajajaj that was code for you? 😂😂😂
The woman behind you looks Filipino
Tumpak!!! 🇵🇭🇵🇭🇵🇭
@@BlackMixture Pakibati na lang sa aking kababayan! Salamat sa iyong video, Black Mixture. Ipagpatuloy mo lang!
Jjjjjifffff?????
3:54
OMG did you say JIF????But why?
Is it J as in giraffe or G as in Google.
GIF, JIF
it's JIF. he is correct.
2:11 I always parent values with Slider this way I don't need to everytime open script and change values and slider give you control specially in animation
