After Effects Apprentice: Creating Transparency 1

We’re often asked: What’s the difference between editing and motion graphics?

Although there’s always exceptions to every rule, one way to distinguish between them is the way a project is built: Editing projects tend to be arranged horizontally, cutting between different scenes over time; motion graphics projects quite often are arranged vertically, with multiple elements – including footage, text, and other graphics – appearing on screen at the same time.

The logical next question is: How do you see through one layer to the other elements underneath? This is something we’ve written a lot of articles and recorded a lot of videos about, including our most recently released courses on lynda.com. Sounds like a good time for a quick reference to them all.

The core secret is not to rely solely on the Opacity parameter to make the top layers transparent. One approach is to use Blending Modes, where characteristics of both the layer on top and underneath combine to create far more interesting composites of footage. We consider Blending Modes to be the secret sauce that’s missing when many editors attempt to composite together multiple images, and indeed we’ve written numerous articles and released several courses (many of which are listed at the end of this blog post) on creating lighting effects in post as well as the popular “filmic glow” effect. (It’s also the subject of one of Chris’ sessions on Sunday April 10 at the upcoming NAB Post|Production World.)

Another approach is to cut out portions of layers in interesting ways to focus the viewer on interesting features of the footage on top, as well as reveal additional layers underneath. This is the subject of our just-released course After Effects Apprentice: Creating Transparency. This course focuses heavily on creating and animating masks (user-defined cutouts) for layers using simple and advanced tools. We also cover using properties of one layer – such as its luminance or alpha channel – to alter the transparency of other layers: For example, using text to cut out animated background footage to create a video fill for the text shapes. Additionally, we spend a lot of time showing how effects such as drop shadows interact with these techniques to help add definition between the layers in the final composite.
