In this class we discovered the basics of rotoscoping in Nuke.
Rotoscoping is used to create alpha channels ‘matte’ to match the footage motion. With this, we can change the subjects background or create different effects with layering.
In Nuke, we learnt the basic rotoscoping using ‘Beziers’ to create the alpha channel and feathering to soften the edges of it.
This is the matte I created of the running man video the professor sent to us. It is made by parts, starting from the head of the running man down till the legs.
Rotoscoping can be a tedious job in my opinion but with practice and experience it could result in a more quick and pleasant job, as well as in a rewarding experience with the final result achieved.
