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 Youtube bans from this description for some reason..🤦🏾♂️) in between the “n” and “=” in the last line of code.
