My task for this project was to create a 20 second long video and then add something into it tracking the main subject.
At first I was going to track my house cats but when I took the video it was slightly too dark and the cats are all dark colours so the tracking couldn’t pick up on the pieces of the cats that I attached it to so it flicked about and wasn’t fixed to the subject.
After my first failed attempt I was going to record my sheep when I went to visit my parents over the Christmas holidays but in the valleys where my parents live the weather was too bad each day I was there so I had to come up with another plan.
So I decided to record my friend pacing outside the university which to my luck worked out and I finally had my footage to use for my tracking project.
What is tracking?
Tracking is the process of automatically finding a point or series of points from frame to frame in a sequence, allowing you to track to object or camera movement in the shot. The process started as one point tracking which could stabilise a shot or add matching motion to a composite.
‘Match moving is a film technique that allows the insertion of computer graphics into real life footage with correct position, scale, orientation, and motion relative to the photographed objects in the shot. The term is used loosely to describe several different methods of extracting camera motion information from a motion picture. Sometimes referred to as motion tracking, match moving is related to rotoscoping. Match moving is sometimes confused with motion capture, which records the motion of objects, often human actors, rather than the camera. Typically, motion capture requires special cameras and sensors and a controlled environment (although recent developments such as the Kinect camera have begun to change this). Match moving is also distinct from motion control photography, which uses mechanical hardware to execute multiple identical camera moves. Match moving, by contrast, is typically a software-based technology, applied after the fact to normal footage recorded in uncontrolled environments with an ordinary camera.’
