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

Roto: It can create a mask to assist with operations such as tracking and cutting.

Merge: merge node can be used to merge two footage into a single frame.

  • Here is the outcomes

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.

  • The second practice

I’m getting more and more proficient with this skill.

  • Third 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.
