Compositing is any creative work that involves layering multiple design elements together. With nonlinear editing systems like Premiere Pro, compositing makes use of alpha channels. This chapter explains the core technologies behind the creative tools.
What is Compositing? What is RGBA?
You might think that you need to jump into After Effects to do compositing work, but Premiere Pro has powerful tools of its own for that purpose. This lesson gives an overview of the kinds of results you can achieve without ever leaving your editor.
To fully understand compositing, you need to begin by understanding how editing systems create partial opacity for pixels. This lesson will give you a core understanding of this fundamental technology.
Probably the most basic and common form of transparency adjustment is the opacity control. This is so common, Premiere Pro makes it the default keyframe adjustment on the Timeline. This chapter looks at the ways you can make keyframed adjustments to opacity using effect controls and the Timeline.
The Effect Controls panel starts off looking simple but can quickly flower into an advanced Bézier-controlled keyframing heaven. This lesson shows you how.
Premiere Pro gives you advanced keyframe controls directly on the Timeline. This lesson shows you how to use those controls to achieve advanced compositing results in context with the rest of your media.
Garbage mattes should really have another name. Something like "amazing mattes" would fit better, since these simple effects combine with others to create some of the most advanced compositing tools in Premiere Pro. This chapter introduces your new best friend in the world of compositing.
This lesson shows you how to add garbage mattes to your clips to create precisely layered compositions.
Luma Keys calculate which pixels should be transparent based on their luminance values. They work best when you plan for them in advance and shoot with appropriate lighting. This chapter introduces the unsung hero of compositing.
This lesson introduces the main controls for setting up a Luma Key effect.
The Ultra Key effect was originally part of a suite of tools intended to create virtual sets. The keyer in that suite was so good, Adobe put it into Premiere Pro. It provides super-fast, high-quality keys and this chapter shows you how.
The Ultra Keyer
This lesson explains the primary controls you will use to create a key with the Ultra Key effect.
Nesting allows for some of the most efficient workflows and advanced effects work, but many editors are not familiar with it. This chapter introduces sequence nesting and gives some examples of how to use it.
Though it seems more complex to begin with, nesting can speed up and simplify the editing process. This lesson introduces some of the common ways editors use nesting.
