I got a request from one of the patron in membership of 松 -Matsu-
I will explain about 合成/Gōsei of anime production separating some articles because 合成/Gōsei is too much complicated. So I'm going to take a time
合成/Gōsei is meaning that "composition" or "combined" or "mixed" in English.
Compositing two materials or more bigger number materials
We usually use this technics when we want to express the animation like this,



In short, in 合成/Gōsei section, we will make two kind of materials fixed version and moved version in Douga section, afterwords we will composite these in Shiage/仕上げ... painting color section or Sastuei/撮影 ... composite section

*By the way, we call the finished clean-up or Nakawari pictures "動画/Douga" ( in this case, 動画 is not meaning "A video" or "A film"
○Kind of 合成/Gōsei
⚫︎線合成/Sen-Gōsei ... Compositing two kind of materials of line-art, before colored
⚫︎面合成/Men-Gōsei ... Compositing two kind of materials of surface, after colored
⚫︎セリフ合成/Serifu-Gōsei ... The name that we usually use Gōsei for its 口パクKuchi-paku (lip-sink)
⚫︎かぶせ合成/Kabuse-Gōsei ... The name of one of 面合成 technic. When we replace the part of Douga to new one, we call this action "かぶせ修正/Kabuse-shūsei"
⚫︎多重合成/Tajyū-Gōsei ... Using multiple 合成/Gōsei
I will explain these one by one from next time
