Free After Effects CC 2014.2+ Animation Preset: Responsive Auto Scale (Creative Dojo)

Overview

Creative Dojo shares a preset that makes a layer responsive, dynamically resizing it to fit a set width or height. It was designed for text layers but works with most layers, which helps lower thirds and fixed-size template layouts keep their shape.

Options include restricting upscaling and left, centred or right alignment, and it requires After Effects CC 2014.2 (13.2) or higher. The .ffx preset is pay-what-you-want from $0 on Gumroad.
