How to Animate a Smooth Text Reveal in After Effects (With a Script)


In this tutorial, you'll learn how to use After Effects scripts. You'll see how to use a text animation script to apply effects easily in your projects.

Labor Saving Scripts for Adobe After Effects

Adobe After Effects is the premier solution for creating animations and motion graphics, used for everything from hobbyist projects to Hollywood productions. It's a professional-grade video app with features to create practically any animation.

The challenge is in learning all the tools. If you don't have the time to invest in mastering After Effects from the ground up, you can skip ahead by using pre-built projects.

In this tutorial, we're going to work with a script—basically a little bit of programming that adds extra features to After Effects—called Curva Script. It's a beautiful way to animate script text in After Effects.


For comparison, check out this example of a project built from scratch in Adobe After Effects in the tutorial below:

Where to Find Adobe After Effects Scripts

The best place to find top After Effects scripts is Envato Market. This site has some of the most powerful scripts that you can use to create a deep variety of animated videos.

A quick glance at Market's library shows scripts that can help you do all of the following:

  • aw_PreviewGenerator—generate GIF previews of your After Effects projects
  • Cartoon Style—re-create some of your favorite cartoon effects with just a few clicks
  • Chartz!—animate your data to life with this script, perfect for financial and data-driven presentations
  • ParaLight—create parallax and pseudo-3D animation

All of these scripts condense complex After Effects operations into a few steps. Even better, they're typically well-documented and customizable so that you can match them to your project's purpose. 

After Effects Scripts
Envato Market is home to quality of scripts and templates that you can use in Adobe After Effects to help you avoid designing everything from scratch.

In this example, I'm going to work with the Curva Script tool for After Effects that I showed above. Let's learn how to use it.

1. Install Curva Script

First, it's important to note that every script features a different installation process. It's important to check the documentation that's included in each project so that you can follow the installation correctly.

In the case of our example, there are a few steps in the documentation that we need to follow before using Curva:

  • Moving a ".jsxbin" file to the After Effects / Scripts folder (valid on both macOS and Windows)
  • Enabled an option to let scripts talk to a web server (see screenshot below) to register the Curva Script license
  • Entered your license key

Curva Script requires activation. You'll need to adjust an After Effects preference so that scripts can access the network. On the After Effects > Preferences menu, find the Scripting & Expressions section and make sure Allow Scripts to Write Files and Access Network is ticked.

Turn option on
Because Curva needs activation, you should go to the Preferences > Scripting & Expressions menu option and tick Allow Scripts to Write Files and Access Network.

Again, these steps are going to vary based upon the individual script and version of After Effects that you're using. It's important to check the documentation so that you use each script properly.

2. Convert Text to Shapes

Let's walk through an example of using an After Effects script. The purpose of Curva Script is to add a nice animated, hand-scripted effect to your text. In my example, I started by typing text onto a new composition.

Now, you'll need to convert the text to shapes so that Curva Script can work with it. Right click on your text and choose Create Shapes from Text to convert it. 

Create Shapes from Text
Right click on your text and choose Create Shapes from Text to begin working with it in Curva Script.

Now, we're ready to start working with the script. If you can't already see the Curva window, go to the After Effects > Window > Curva Script to open up the panel.

3. Apply the Script to Animate

Applying the script effect requires selecting the individual letter shapes and animating them. On the timeline, open up the text letter and find the first individual letter. Select it, then click on Animate on the Curva panel.

Select from layer
Open up an individual letter path from the layers on the timeline to start animating it.

On the pop-up window, you'll see an outline of the letter that you selected. You'll want to click on two consecutive green points on the shape so that you can animate the letter. Choose those consecutive points, then select an Animation Type dropdown for various effects. Then click OK to lock in your animation.

Click on letters
On the Curva pop up, click on two adjacent green points on the letter shape to set where the animation starts.

That's it! Just repeat this process with each letter layer to create a scripted animation.
