This week, we mainly learned Rotoscoping, a technique that can trace and cut the part of the objects in the footage.
There are several nodes that have been introduced

Hair edge is a big problem for this work. Another thing is that a normal speed footage might be a better choice for me to practice.

After finishing these three projects, I am quite familiar with rotoscoping. Besides, I find that this is a job that requires a lot of patience and practice. If you want a good result, you need to put the time in. However, I still have a problem with the hair edge. I wonder if Nuke has a tool like channel matting in Photoshop that can cut the irregular edge perfectly.
