Previs是Previsualization的缩写，有人将它称为视觉预览，预演，预览，也有人把Previs形象的叫做“动态分镜”，“3D故事板”，更多的人在表达这个概念时会直接说Previs，像Roto，Layout一样直接用英文。说“预览”的话，会容易和动画环节的Preview预览混淆。也有人将英文写成PreViz，因为是Previsualization的缩写，但国外专业Previs公司已统一使用Previs。随着技术的发展和需求的出现，Postvis也应运而生。
用直白的语言来说，Previs其实就是在正式拍摄之前将拍摄内容简单制作一遍，用低模，简单动画展示出演员走位，取景，摄影机角度，摄影机运动等大方向，供导演，摄像指导等人拍摄时参考。过去，电影人靠的是分镜，概念图，实体模型道具帮他们规划视觉呈现。现在的Previs团队可以通过计算机动画工具来完成、加速这个过程。
Previs对导演和制片人来说都是个双赢的流程，它不仅将飘渺的创意具体化，而且确保了拍摄和后期制作的效率。从文中的大片Previs视频大家就不难看出，很多优秀的Previs同最终成片已几乎一模一样。Previs团队制作出Previs，导演提N轮反馈之后通过，然后导演再按照这个Previs计划来实施拍摄。很专业，很顺畅的节奏。Previs除此之外还有个很强大的功能，就是拉投资。形象、动态的视频比文字剧本更容易让对方明白这部电影的方向。

FXPHD PVS101 Introduction to Previs
This course aims to give members a solid base as to what previsualisation is, as well as the tools and workflows used to create previs for feature films and commercials. Taught by Clint Reagan, the course is a combination of interview/lecture-style classes as well as application-based classes that will take members through the previs workflow.
We’ll begin with an overall look at the industry, beginning with what we mean by previsualization and how it relates to pitchvis, postvis, and virtual cinematography. This course will concentrate on previs as a production-side tool for creative storytelling, working with the director to flush out ideas before filming. For the second half of the course Clint will work through a sample project, demonstrating the tools and techniques he uses on the job for his projects.
By the end of the course, members will be armed with a solid knowledge of previs, including key workflow and tools to get the job done. Even if you’re not looking towards a career specifically in previs, many of the principles can be used on projects to help explore creative possibilities as well as speed up the finishing process.
With more than 10 years of experience in the field, Clint recently supervised previs for Ridley Scott’s Prometheus, as well as the blockbuster adaptation of The Hunger Games, directed by Gary Ross. Reagan’s other films included McG’s This Means War, G.I. Joe: The Rise of Cobra with Steven Sommers, and Knight and Day and The Wolverine for James Mangold. Clint recently wrapped on two tent pole films due out in 2013 and 2014, respectively. He is currently supervising on a fun-filled 2014 film.
