Visual Effects Terminology - Week 13

In the last blog post's video, a number of visual effects terms were presented, but I was unfamiliar with them. To increase my understanding of post production, I will define the terms now.

1. Plate: Visual Effects scenes and can focus on the forefront, middle, or back of a scene. http://effectscorner.blogspot.com/2007/05/visual-effects-supervisor.html
2. Raw Plate:  Regular footage of a film before the process of special effects.  http://entertainment.howstuffworks.com/golden-compass.htm
3. Holdout Matte:  The holdout matte shields the film for being exposed in certain areas. Black parts of the matte shield, while the white lets light and imagery imprint onto the film. http://www.oocities.org/~special_effect/st_comp_effect.html
4. Diffusion Pass (Diffuse Pass or Beauty Pass): a completely rendered model that contains diffuse lighting among other attributes. http://www.3drender.com/light/compositing/index.html
5. Previs: Developing the look of a shot such as implementing storyboarding. http://en.wikipedia.org/wiki/Previsualization

Other terms I couldn't really find a solid definition for is Matte Vector(which is probably just an image made of vectors) and Beauty Model and Beauty Matte ( probably just the best form of an image ).
