Rotoscoping and Mask Tracking Techniques

In this chapter, we will look into rotoscoping using the Roto Brush tool and mask tracking. These are two essential techniques used in video editing and compositing. These techniques are utilized to isolate and manipulate specific sections of a video or add visual effects to targeted areas, unlocking new creative possibilities. They enable object isolation, intricate animation creation, precise color correction, and the integration of compelling VFX. We will also learn how to use the Content-Aware feature in After Effects, which lets you remove unwanted objects or areas from video footage.

The main topics we will cover in the chapter are as follows:

• Using the Roto Brush tool for quick and precise rotoscoping
• Using the Pen tool to create roto masks
• Tracking masks on moving objects using built-in tracking
• Removing unwanted objects from video clips using Content-Aware Fill
