Mask Tracking in Adobe After Effects is a powerful feature used to follow a subject or object’s motion within a video clip, enabling you to apply effects, blur, or isolate areas precisely. This is especially useful for tasks like face blurring, color correction on moving objects, or creative effects.
✨ What is Mask Tracking?
Mask Tracking allows a mask path to follow motion in a video clip. Once the mask is created, After Effects automatically analyzes the video frame-by-frame and adjusts the mask's position accordingly.
