Expressions can really change the way you work within After Effects. If you want to get serious about it, you can start writing your own expressions to do all kinds of things for you. But you can also start building a library of simple expressions like the ones above to be more efficient and give you more creative control over your work. This expression has the advantage of using the speed information coming from a layer's position and applying it to whatever parameter you want it to influence. For example, if you are moving a layer through a comp, and want the speed of the movement to influence the brightness of the layer, you would just copy and paste this expression to the.

If you want to take the speed for a layer's postional value, you can use the following expressionThis expression has the advantage of using the speed information coming from a layer's position and applying it to whatever parameter you want it to influence. For example, if you are moving a layer through a comp, and want the speed of the movement to influence the brightness of the layer, you would just copy and paste this expression to the 'Brightness and Contrast' filter, in the Brightness parameter. Why the /3-50? Simply because the speed of the layer's position is expressed in 100's (i.e the speed can go from 0 pixels/s to a quite large amount), whereas the brightness goes from 0 to 100. So if you divide the values for speed by 3, you arrive to a decent value for brightness (the brightness won't be overblown). The -50 adds more control to this, putting the brigthness down by 50. You could change this for any other number, depending on your needs, but you could also not use it and divide the speed by 5, or more. by malex Keywordsspeed, velocity, movement(Min.

Expressions are the best tool to enhance your animations
Hey there! Today I’d like to share with you my favorites Adobe After Effects expressions. Your expressions add value to your work. It automates the way you animate your assets, it makes calculation and solves algorithms for you. Audio equalizer for mac os.
How do I integrate an expression ?
Simply go to the property you want to animate and Alt+Click the clock! A text area appears, here is your expression editor area!
Math.round
When you need to round an expression, exemple : a slider effect on an animated text (I did a tutorial on this function, go check it out!).

Blackweb rgb wired gaming mouse. First, enable the timeline remapping in Time > Enable timeline remapping, extend the composition far enough, then apply the expression (Alt/click on the property clock in question).
Wiggle
You can apply this expression to a lot of different property, for example: position, scale, opacity, rotation and others…
After Effects Expression Linear Position Formula
This expression will be wiggling from “a” to “b”. You’ve got to replace those two values by numbers. For example “0” and “100” on the opacity property if you wanna make a random effect from 0 to 100%.

Apply the following expression to a property to start wiggling it at time 2 seconds and stop wiggling it at time 4 seconds:
How to make wiggle expression looping ?
Interesting thing to know if you wanna make the wiggle expression looping ! Read this article from motionscript.com. Thanks to Florian for the contribution :-).
Here is a pretty good set of expressions, very usefull, by Emanuelecolombo.it!
