This is the highest level I've seen on a tutorial... like ever.
Perfectly planned out, explains all the details and no wasted time.
I rarely comment on stuff, but this tutorial deserves some serious love.
Thank you!!!
thank you for the kind words. I'm glad it ticks all the boxes for you.
the amount of work that was done before opening after effect to explain it is amazing i love it thanks !!
I'm fascinated by the animations used to describe the concepts in this video. Just blown away at the quality of this content.
Have watched quite a lot of tutorials for expressions and I have to say that this one is really ON POINT .
Best tutorials on youtube. Thank you, Evan.
The patient, concise and CLEAR explanation of the set up of variables has been profoundly useful - THANK YOU!!
I really love the effort you put on to demonstrate how it basically works in the beginning! Thank you for the tutorial.
You're very welcome. Glad you enjoy it. I'm going to try to stick with this kind of format for basic expression tutorials moving forward.
This is incredible. Thank you so much for all this effort to make something great!
This is amazing. I'm definitely going to rewatch this video just for the beauty of it. Thank you for creating this tutorial
This is just so calming to watch . bless you for being so generous with your knowledge and c reativity
daaaamn, you really went all in with the sine explanation. Super Impressive!
When I'm in I'm all in. I'm truly disruptive at a poker table, and out very quickly.
I just had to say that i really enjoy to saw ur toturial ! one of the best out there! thanks for shering ur wisdom with us!
What an epic 13 mins!! , Great as always.
Absolutely stunning tutorial. Jaw dropped watching that opening example animation. Wonderful visual
Well, thank you very much. Dropping jaws and knowledge up on this channel :)
ECAbrams Every damn time. Learnt so much from you over the years. Thank you.
Thank you for breaking this down in plain english! I am not math-minded and have hesitated to learn expressions because it's not the easiest thing for me to pick up immediately, but the clear explanations paired with accompanying visuals made this soooo much easier to understand. I also appreciate your delivery -- digestible for a beginner without skipping over the basics or sounding condescending
This comment has made my morning. There were definitely earlier scripts and recordings that were a bit too "math-splaining". I feel like taking the time on this was just validated :)
i have never seen graph editor looks so beautiful like a heartbeat. what an amazing expression
Wow, you successfully explained a subject that even after months of studying it in high school nobody understood.
there's no way I would've cared or bothered with learning about this function had I not discovered this beautifully crafted tutorial. THANK YOU
Best tutorial start I've seen. Lovely animation. Outdone yourself on this one!
Damn! You have such a pleasant voice for these kind of tutorials. Now I can listen to them all day!!!
Absolutely awesome intro and tutorial!
Thanks.
The level of execution for a tutorial is mind-blowing. Thank you.
Glad you liked it!
you just saved me hours of painstaking matching of key frames in different stroke modifiers. thank you.
Bruh this is freaking hard!
Thank you so much for such an indepth tutorial!!
I'll make sure to use these expressions in my future projects!
Copy. Paste. Pray.
Love it. Excellent (and beautiful) explanation as always good sir
Thank you so much for concise and clear explanation explains! Absolutely stunning tutorial!
Glad it was helpful!
Entertaining and informative, and nice and concise. Thanks for another great tutorial. I read Marcus Geduld's book recently as well. Dan Ebberts. Genius. Keep making these!
I'll try my best. :) glad you enjoy it. I try to keep these under 15 minutes. I don't always succeed but that's the goal.
So happy for found this channel! Thanks for the amazing tutorials
Well, thank you for saying so. Glad you like what I do here.
A carafe of wine, After Effects, and this beautiful explanation of Math.sin. I sat here all evening tinkering along with this tutorial.
THANK YOU.
Another excellent tutorial, easy to follow and clearly explained. Even inspired some work I did on a recent project. Thanks!
That's fantastic! This is actually one of my favourite pieces to have made... but don't tell the other tutorials.
This is why I love your tutorial!
Yo are amazing!!!!! Thank you for the excelent tutorial. Keep it coming!! Love AE expressions, such a great topic
Something a friend used this function for - A Newton 2 Physics simulation that kept the rotation of items "mostly upright" as they bounced around.
This was even better than your usual good stuff!
Hello, thank you for this wonderful tutorial. The little plus would be to put a link in the decription when you speak about a previous tutorial, like the time expression ^^
Thank you so much !
You are a genius Evan!
Shout out to you!
the best ae tutorial ever please do more on expressions
Amazing tutorial. Thanks a lot. You are the best.
Best of the best. It's explicit and easy to understand to math dumbass like me. You can't find a better tut to explain Math.sin online. Truly appreciate and salute your effort.
I would love a video on how you plan out these videos, not just the techniques, but the creative process. I recently discovered your channel, and I really enjoy it! (and your voice is very comfortable)
Thank you very much. I'm trying out some new audio gear here so I'm glad my voice is comforting, rather than powerfully grating. It might be my Canadian affect. We could get into some process stuff. I do often get into that on live streams, which is also a thing that happens on this channel.
Excelente!! Como aporte comento que en las nuevas versiones hay que definir x, y, a y f con var o const o de lo contrario dará error.
Saludos!
i really , really like the new style keep it up Charles
AMAZING EXPLAINATION & ANIMATION!
Loved the motion graphics explanation of the function!
Things are getting real meta over here. Using motion graphics to explain motion graphics concepts. Wheels within wheels.
Thanks for the tutorials EVAN :)
I love your editing style. Lots of love❤
simple explanation ... easy to understand ... thanks you
I am wordless. Thanks for this great tutorial .......
DAMN, AE IS MUCH MORE COMPLICATED THAN I THINK.
THANKS TO YOU, THIS VIDEO EASE MY MIND :)
Thank you so much for this tutorial!
You're ability to animate your storytelling has become ridiculously good and your animated logo is awesome!!! Are you just writing command codes nonstop nowadays?
This was seriously helpful. Could never quite figure out how to work in that Math.sin expression. Math.exp next? Loveya
Perhaps. I don't use that one as much in my work. I think we may get into some of the random functions like random() and noise(). But we will certainly come back to the Math family soon enough :)
Awesome channel, happy to find it
You have done a great job! You don't know what it means to me.
Absolutely amazing
Mazing explanation of each concept with fabulous visuals. Thank you
I'm glad you like it. This is one I'm particularly proud of. Would love to have the time to make more like this soon!
@@ECAbrams Looking forward to more. Just click the bell icon ;)
Thank you... best style of explain.....
waaaw, this is really inspirational
I wish you continue feeding us such valuable knowledge
i'll try my level best
Cool tutorial! Great job!
Thanks for the tutorial!
GREAT TUTORIAL BY THE WAY!
Great stuff, thanks for explaining! The buttery voice certainly helps :D
Thank u very much, Sir you teach us very well, brilliant work, biggest like fully played, stay blessed sir
I like the new intro, very cool!
Great work, Thanks!
great tutorial, thanks!
Besides subtracting in-point time from current time, you can determine the phase (in radians) of the wave according to y=a*sin(2*Pi*f*time+phase) but it gets a little sciency. Your solution is easier.
Excellent thanks for sharing Evan. I appreciate the graphics, especially the copy & paste anim! Your clarity and detail is by far more valuable than ChatGPT ;)
Finally a rare win for humans.
Amazing thanks so much. Such a brilliant tutorial
Thank you so much.
Balls to the walls on the animation for this one 👏👏👏
Nice guide cheers!
Eca is a legend!
Math.sin() - The entire swinging motion occurs from this expression. Math.sin() creates a sine wave, an
occilating value positive and negative from the original starting value it is given. There are two values
that you can give this expression to effect it’s output. The first being it’s source value,
Math.sin(SOURCE VALUE). This is traditionally assigned to time, since time’s value increases
exponentially with each frame of your After Effects timeline. The second value isn’t really mentioned
anywhere, it literally is an optional modifier where we basically multiply the resulting output value of
Math.sin() by another value. This increases it’s overall resulting value. You do this by using the “*”
multiplication operator. So Math.sin(time)*20 will produce a value 20 times greater. In addition to
modifying the final result, you can also modify the speed of time in the same way. So
Math.sin(time*2)*20 will make time move 2 times as fast with the same 20 times greater value.
Always amazing. Always.
you're the reason why im into after effects
I'm glad to hear it. Hopfully your adveutres with Ae are always fun and worthwilse.
Man why I didn't see this earlier ♥️♥️♥️ love this very much ❤️
What a great artist.
Fantastic! Awesome.
absolutely great value, thanks so much
But was it great valueAtTime? A little expression humour for the comments section.
Well done!
Math is cool in After Effects! Thank you!
Math is cool everywhere!
FINALLY THANK YOU
Amazing 😍
Thank You!!
this is soooooo usefull! thank u so much!
Very good!!!!
Thank you!
It´s the most beautiful tutorial
Thank you so much. I do enjoy being extra with these expressions pieces.
Wonderful!
Evan, is it safe to assume the intro section from 2:29 onward (the black and blue wave shapes) was created using Wave Warp or is there some way to apply Math.sin to shape paths?
Recalling the function y = A sin(kx + c) + d from math class!
Wooo... Great... Thanks Dear
Amazing Explanation
Glad you liked it
You always surprise me.
pretty interesting vid!
great video
GOD BLESS YOU!
@ECAbrames thanks for greate tutorial.is it possible to connect variable parameters of expression to slider?i want to animate variable parameters in expression.
A very didactic tutorial, thank you very much.
I had already guessed how to move objects along a sinusoid, but what I would like to do is draw a sinusoid. Or any other mathematical curve.
Is it possible ?
I have the same question! I want to make waves like the wave from 2:55 to 4:17
Beatutifully animated Tutorial! I would love to know how you animated the actual continuous sine waves tho ... i cant seem to find a method to, for example, make a path behave like a sinewave in order to make a circle follow it like you did in the intro...
Cheers
So, in this case I'm actually using the wave warp effect to make that line. Wave warp can deform layers into sine waves. There is a but more to it, like lining up the values so the circle seems to flow on the wave, but that's the start. Does that help at all?
I feel very smart after I watched this tutorial. call me Mr. professor now!
Mission accomplished!
