Part 2: How to Use Loop Expression in After Effects If you use a Modifier of 2, AE will repeat the animation between the previous 3 Keyframes. It is essential to note that the number doesn’t directly refer to the Keyframes but to the animated section between Keyframes.įor example, if you use the Loop Out property with a Modifier of one, AE will repeat the animation between the last two Keyframes in the timeline. When using the Duration based Properties, the Modifier will instruct AE on the number of seconds to repeat.įor the Loop In and Out expressions, the Modifier can be used to tell AE how many of your Keyframes you want to apply the loop to. The Modifier is the final instruction to After Effects, and in some cases, it is not needed at all. There are four Loop Types available (“Pingpong”) The Loop Type is where you decide the type of animated loop After Effects will create. In general, the Duration loops are not massively helpful but can save you a lot of time if, for example, you want to be able to quickly adjust how long the loop takes without changing your keyframes. To do this, you’ll need to add a modifier, which we will discuss below. LoopOutDuration and LoopInDuration: These two are slightly different, as they allow you to tell After Effects to base the loop on Seconds rather than Keyframes.
LoopOut and LoopIn: As you can probably guess, each of these Loop types tells After Effects whether the loop starts before or after your keyframes. There are four types of Loop Expression properties. loopOut(“pingpong”,1) The Property – loopOut(“pingpong”,1)
One of the most used Expressions in animation is the Loop Out Ping Pong effect, which we will use for this example. Together, these three elements create a command that After Effects can use to loop your keyframes in several ways. There are 3 distinct sections to any Loop Expression the Property, the Loop Type, and the Modifier. The first thing you’ll need to understand is how an Expression is formed.
