Eventually you will need to create and animate some text bubbles. Maybe for a motion graphics piece, maybe for a commercial spot, or maybe as exposition in a film. Creating an animation with a speech bubble that is filled with text is pretty simple. The problem because how do you do it in a way that is easy to change, you know, in case you have a ton of them to do? There is a way to make dynamic text bubbles in After Effects.
With these dynamic text bubbles, you can easily swap out text and have everything work automatically.
What is a dynamic motion graphic asset in after effects? Dynamic, meaning that you can type in text and the bubble will automatically alter its shape to fit the number of characters. How is that all set up? Mikey Borup shows one way, using of course expressions in After Effects. Once it is all set up, you can easily alter the type and create a text bubble conversation in no time.
