This week, we learnt have the basics of how to rotoscope on Nuke. We were given a video of a running man, and taught the nodes, different points and techniques on how to rotoscope his body frame by frame. We created a sequence of nodes by just pressing ‘O’, which brought up the Rotoscope nodes in Nuke.
In the session we played around with the rotoscope tools such as Bezier, and practised drawing around the man’s body parts frame by frame. We started with the head, being the most easiest part as this moves the leaast.
We then looked at tools such as motion blur and matte overlaying what we have rotoscoped. When I was more comfortable with the tools, I worked on putting the Bezier around the arms. I also learnt how to change the viewer to show the rootoscope in alpha mode, so you can see the shape you have created better.
Work from Home
As homework we had to rotoscope the whole 100 frames of the man’s whole body running in the scene. I split the parts into head, left arm, right arm, chest and legs to make the transitions easier to change frame by frame. The part I found challenging was keeping the matte overlay of red on the roto nodes. For some reason this kept removing itself. However I figured out I had to select the overall viewer to be in matte overlay intead of rgb, and this was resolved.
When I comppleted this I struggled with the rendering a bit, but soon realised that the codec was in the wrong encoding selection. I then uploaded this mov file to the homework folder.
