In today’s class we have learned the basics of Nuke’s user interface and have been introduced to the concept of “rotoscoping”.
Rotoscoping is a process of masking then separating the elements (either person or object) in the frame that would need to be manipulated, by manually drawing masks and keyframing the movement of the said object as accurately as possible.
What we also learned to avoid to do is:
- Avoid doing a single roto node/spline for a complicated subject (humans, animals etc.) Instead, do separate splines for each smaller parts.
- Lookout for motion blur and fast moving subjects.
- Avoid drawing/moving roto for every single frame of the shot. Instead, try skipping ahead a few frames to see if it can be done with the least amount of keyframes
- Avoid drawing too many spline points (Less is better!)
- DO Try to use tracker to assist in roto when possible (static object with no complicated movements)
