Tracking and rotoscoping are part of almost any visual effects project. For 2D tracking, point trackers are most commonly used, but to get good point tracks requires a mix of experience and luck. You often have to “prime” a clip for optimum tracking using color correctors and other image manipulations. If the point being tracked exits frame, you get into offset tracking, which presents its own set of challenges. Carols For A Merry Tubachristmas Pdf Printer. If it all fails, you are into hand tracking, which is time consuming and very hard to get accurate.

Instead, Imagineer’s Planar Tracker tracks an object’s translation, rotation and scaling data based on the movement of a user-defined plane. A plane is any flat surface having only two dimensions, such as a table top, a wall, or a television screen. Planes provide much more detail to the computer about an object’s translation, rotation and scaling than is possible with point-based tracking tools. Even as an object leaves and enters a frame, there is usually enough information for the Planar Tracker to maintain a solid track of the object. When you work with the mocha tools, you will need to look for planes in the clip. More specifically, you will need to look for planes that coincide with movements you want to track. If someone is waving goodbye, you can break their arm into two planes - the upper and lower limbs.
