After Effects Lip Sync Script - CarlsOpacityYcontroller

My good friend Carl F. Corneil has made a fantastic After Effects script that allows you to do lip sync in After Effects in a second! Usually, you'll have to key every mouths opacity manually every time you want the mouth shape to change. Luckily, not anymore! This scripts allows you to slide a controller in the Y-axis to automaticly change to your desired mouth.

This is a quick and easy tutorial on how to use the script:

- First, download the script at the bottom of this post. Unzip the .jsx-file, and add it to the scripts-folder in your After Effects folder.

- Open After Effects (should even work on old versions).

- Make a new composition and import your mouth layers. Position them as you like.

- Then, go to Layer->New->Solid (you can also use a null object). Make the solid a small size like 100x100 or something. Name the layer "controller".

- Select the "controller" layer first, and then select all the other mouth layers. Go to File->Scripts->CarlsOpacityYController

Voila! The opacity on your mouths are now magic! Try taking the "controller" and move it in the y-axis (up/down)! As you can see, the mouths change according to where the controller is positioned in the y-axis.

In the "effects"-panel, there is a slider control. Adjusting this value, changes the amount you'll have to move the controller for the mouths to change. A really handy feature if you use very many/few mouths!

Thank you so much to Carl F. Corneil for making our lives easier!
