Previs, Postvis, Techvis & Animation roles in VFX, Film, Games

Introduction

I think this lesson is very interesting! Not only because I learned new concepts, but also because I heard Luke talk about his experience working in the VFX industry. This is more conducive for us to have a deeper understanding of the areas we can work in the future, so as to consider the positions we can do.

Previs & Postvis & Techvis

Previs:

Previs is aimed at being able to realize the best creative ideas most effectively. Previs artists and editors model and 3D-animate digital versions of the action so that a director can see and test concepts quickly, determine how best to tell the story and make the most of their time on set. They can also work out potential camera angles and edits, and discover what coverage they might need.

Postvis:

Postvis sequences give post-production artists a much clearer understanding of the director’s intent, and provide VFX teams with digital assets that can be used simply as reference, or upgraded directly for use in the final imagery. With an approved postvis sequence, the bidding process for final VFX becomes much more accurate and straight forward. Postvis allows VFX teams to focus their most detailed efforts on elements that are going to be featured closest to camera.0304

Techvis:

techvis can help answer production questions both large and small, and explain how many interconnected pieces fit into the grand puzzle, including the critical relationship between camera rigs, actors, extras and visual effects elements.

It takes many forms, from a single PDF, to hundreds of schematic diagrams and simulation videos that reveal how each shot can be accomplished.

Animation roles in VFX, Film, Games

VFX:

Visual effects is the process by which imagery is created or manipulated outside the context of a live action shot in filmmaking and video production. The integration of live action footage and CG elements to create realistic imagery is called VFX. This means that special effects animators need to process the characters and data shot through green cloth, blue cloth, motion capture, etc., to create animations that are close to real life and conform to the laws of reality.

Film:

Movie animation may maintain a part of the realism, which is supported by continuous advancement of technology. But the more important thing that has not changed is the basic animation principles. Taking Disney as an example, the character’s performance will be exaggerated, and even in order to achieve this effect, animators need to deform the character.

Games:

The biggest feature of game animation is interactivity. This urges animators to do loop animations to ensure that actions and actions can be directly and smoothly connected. For example, an animator needs to create a idle state, a walking loop, a running loop, and a jumping state, so that every action can be smoothly connected when the player plays the character.
