In this lesson we are looking at Rotoscoping.
We manually drew around and cut out objects from movie frames so that the required parts of the image can be used, this is known as rotoscoping. We can use this to change the subjects background or layer effects. I went through each frame adjusting the points until they matched the running mans limbs.
The parts of an image that are wanted after cutting out are known as mattes.
We used the ‘Beziers’ tool to draw around and create an Alpha channel for the running man.
