All About Expression Controls

Expression Controls are effects that don't seem to do anything to our compositions! But they work as UIs for expressions we create. In this post, we'll take a look at each individual control and see what it can do and how to make use of it.

Change Multiple Comps from a Single Master Composition with Expressions

Okay, here's the scenario, an editor has created promotional material for a few shows. The channel he's working on has specific graphics that I need to make. So, I need to make, for each show, a graphic that shows the name of the show and different versions that say "Tonight at [specific time]", "Next Week", "This Week", "Coming Soon" and so on. Here's how one of them looks:

The problem is there's 6 versions and 4 shows, 24 comps in total. I can't keep rendering, changing text, rendering; it is kinda tiresome and is more prone to mistakes!

This tutorial will take a look at how to set-up your project so all you have to do is change ONE composition and create all 6 variations per show in one go. So technically, I only have to change and render 4 times, as compared to 24.
As always, this technique can be used for anything that requires batch editing and rendering, so adjust it for your specific uses.
