Tracking
Tracking in post-production is the analysis of motion within a shot to follow specific features, regions or surfaces across frames, used for everything from stabilization to compositing to color grading. Several tracking types exist: point tracking (following individual features like a corner or distinctive mark), planar tracking (following the perspective of a flat or near-flat surface like a wall, screen or sign), 3D camera tracking (solving the entire camera path through space, see matchmove), object tracking (following a deformable subject across frames, often for roto purposes), and AI-assisted tracking (modern Adobe Sensei, Resolve Magic Mask, DAIN-based tools). Each has its applications: point tracking is the cheapest and oldest, used for stabilization and basic motion graphics; planar tracking (Mocha Pro is the industry standard) excels at sign replacements and screen inserts; 3D tracking is foundational for set extensions and CG element insertion; object tracking enables roto without manual frame-by-frame painting. In color grading, tracking attaches a power window to a moving subject so the grade follows them through the shot. In motion graphics and titles, tracking attaches text or graphics to a moving surface. Tools span the simple (Premiere Pro built-in trackers, FCPX SmoothCam) to the specialized (Mocha Pro, SynthEyes, 3DEqualizer). A tracker's quality depends on contrast in the tracked feature, absence of motion blur, and the absence of occlusions through the shot.
