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!!!

Absolutely stunning tutorial. Jaw dropped watching that opening example animation. Wonderful visual

[hellosabrinachaney]

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

I'm fascinated by the animations used to describe the concepts in this video. Just blown away at the quality of this content.

[AlanCrytex]

I really love the effort you put on to demonstrate how it basically works in the beginning! Thank you for the tutorial.

[gizelgumirov]

Thank you so much for concise and clear explanation explains! Absolutely stunning tutorial!

The level of execution for a tutorial is mind-blowing. Thank you.

[AchHadda]

the amount of work that was done before opening after effect to explain it is amazing i love it thanks !!

[obrienpatrick]

you just saved me hours of painstaking matching of key frames in different stroke modifiers. thank you.

i have never seen graph editor looks so beautiful like a heartbeat. what an amazing expression

[afraidsari]

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

Wow, you successfully explained a subject that even after months of studying it in high school nobody understood.

[MrMuffinLord]

daaaamn, you really went all in with the sine explanation. Super Impressive!

[geeleeggan]

The patient, concise and CLEAR explanation of the set up of variables has been profoundly useful - THANK YOU!!

[chutihudelle]

Have watched quite a lot of tutorials for expressions and I have to say that this one is really ON POINT .

[juanmamaffei]

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!

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.

you're the reason why im into after effects

[hiroober]

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.

This is just so calming to watch . bless you for being so generous with your knowledge and c reativity
