It is the third week of my Internship at Aninzi. This week, we had some works involving with the green screen. The staffs taught us how to set the light to get a good footage, which is easy to key out the green. We should get the sharp edge shadow that leans to only one direction.
Another work that we got is masking out unwanted areas. It is a work for an internet game that use a live action footage. After we key the green out of the footage, some of the unwanted areas which are not green remains at the edge of the character. We use pen tool to draw a mask. The mask is at the substract mode, so everything inside the mask is cut out. We also have to animate the mask as the character moves, so it is kind of a hard work. It is even harder than when we studied in class.
We also learnt about the After Effect plug-in called Ultimatte Advantedge. The staffs use this plug-in to key out greens, and the result is quite good. Therefore, we installed it in our computers.
