Previs
Ive worked on lots of different levels of previz, from 2d storyboard animatics (Eg Kraven) to fully rigged skeletal anims (Eg The Kingsman). Its aesthetic is often not the goal, but i try to keep the mood in the sequence by attempting to maintain the cinematic feeling. This usually goes hand in hand with its uglier but smarter cousin “techviz” of which im also very familiar.
Postvis
Usually Comping with a plate, the complexity of this kind of work ranges but generally ive covered very difficult (Argylle) to simple bg replacement (int). Cant show examples atm sadly.
Final Assets
Graphics or assets on screen. Much higher quality bar, and usually involved in a full fledged design process as well as interacting with delivery pipelines.
