This repository presents a page describing Boris FX Mocha Pro, a professional visual effects tool used in film and television post-production. The README covers planar tracking, rotoscoping, object removal, and lens calibration. Planar tracking is a technique that follows the movement of a flat surface in video (such as a wall, screen, or face) across many frames, producing motion data that can be used to attach graphics or masks to that surface. According to the README, the core tracking engine analyzes a moving surface at sub-pixel precision, meaning it detects motion smaller than a single pixel, and accounts for lens distortion at the same time. This produces tracking paths stable enough to attach digital elements to moving objects in a way that looks physically accurate. The lens calibration module models the specific distortion characteristics of a camera lens, including chromatic aberration (color fringing at edges), and corrects for them before the tracking calculation runs. Rotoscoping is the process of drawing a shape around a subject in video to isolate it from the background, frame by frame. The README describes an automation feature where a shape drawn on one frame propagates across subsequent frames and adjusts for changes in perspective and subject deformation. An object removal feature is described that uses information from surrounding frames to fill in the area where a removed object (such as a crew member or microphone) was visible. A JSON configuration file format is described for saving tracking profiles that specify search area size, sub-pixel mode, lens model, and export format. A command-line interface is described for batch processing a range of frames from a project file without a graphical interface, outputting tracking data files compatible with compositing software like After Effects. Compatibility is listed for Windows, macOS, and Linux. The repository description references a "crack" download, and the README links to a GitHub Pages site.
