Part 1 What is Mocha AE?

As we have briefly mentioned, Mocha AE is designed for planar motion tracking, which is ideal for tasks like adding signs to moving vehicles, buildings, or screens. It’s renowned for its ability to tackle complex visual effects challenges.

Unlike traditional tracking methods that focus on individual track points, Mocha AE tracks "pixel patterns" across entire surfaces. That’s why this approach allows you to handle difficult conditions such as objects moving off-screen, being partially obscured, or footage that’s out of focus. By analyzing multiple points on a plane, Mocha AE calculates and interpolates movement across the surface.

Some of Mocha's main features are:

  • Planar Tracking: Mocha’s Planar Tracker tracks objects based on the movement of flat surfaces like walls or screens. This method provides more detailed and consistent tracking of translation, rotation, and scaling, even when objects move beyond the frame.
  • Masking and Rotoscoping: Mocha offers several spline tools that facilitate the quick creation of roto shapes with minimal keyframing. The X-splines and Bezier splines can be connected to tracking layers, streamlining the rotoscoping process and saving time on masking and tracking.
  • User-Friendly Interface: Mocha AE features a streamlined interface with an intuitive layout, ensuring a smooth workflow for roto, tracking, and data export to After Effects.
  • Seamless Export to After Effects: When exporting data to After Effects, Mocha’s tracking and spline data integrate smoothly, converting to After Effects’ native formats for easy use.

Compared to other tracking tools, many Adobe users in Adobe Community often recommend tracking with Mocha due to its advanced mathematical algorithms that evaluate the plausibility of tracking results, reducing the likelihood of illogical tracks.

Mocha also offers finer control over tracking regions. It lets users exclude specific objects and make other precise adjustments. This makes Mocha particularly effective for tracking shots that are nearly impossible to track with traditional motion tracking methods.

Part 2 Using Mocha's Planar Tracking in After Effects: A Step-by-Step Guide

Now you must’ve wondered how to access and use Mocha in After Effects. If you have After Effects CC, whether through a standalone license or Adobe Creative Cloud, the Mocha AE plugin is included for free. It offers Mocha’s renowned tracking capabilities as well as X-Spline and Bezier tools.

For additional features, you can also purchase Mocha Pro through BorisFX, starting at $37/month. But usually, using Mocha AE is enough for basic planar tracking within After Effects (no need to integrate with other Adobe products like Premiere Pro).
