Previs (Pre-visualization):

Previs refers to the process of creating a rough, visual representation of a project, typically in the form of storyboards, rough 3D animations, or simple computer-generated graphics. It helps filmmakers and visual effects teams plan and visualize complex scenes, sequences, and shots before actual production begins. Previs enables directors and other stakeholders to make informed decisions about camera angles, character movements, and overall visual storytelling.

​

Postvis (Post-visualization):
 

Postvis is the process of creating temporary visual effects or CG elements that are added to footage during the post-production stage. These temporary visual effects are used to provide a sense of how the final shots will look, allowing filmmakers to make creative decisions and plan for the integration of visual effects elements with live-action footage. Postvis often serves as a bridge between pre-production and the final visual effects, helping the director and the visual effects team understand how the shots will come together in the final edit.

​

Techvis (Technical Visualization):

Techvis involves creating detailed technical visualizations and diagrams for complex sequences or shots. It helps in planning the technical aspects of visual effects, such as camera movements, lens choices, virtual set layouts, and tracking markers. Techvis aids in coordinating the efforts of the production crew, camera operators, and visual effects teams, ensuring that all elements align seamlessly during filming and post-production.

​

Layout:

Layout is the process of placing virtual cameras, characters, and other assets in a 3D environment for animation or visual effects purposes. It involves blocking out the scenes and camera movements based on the previs or storyboards. Layout artists ensure that all the elements are properly positioned and timed to facilitate the animation and VFX process smoothly.

​

Composition:

Composition in visual effects refers to the art of combining multiple elements, such as live-action footage, computer-generated imagery (CGI), matte paintings, and visual effects, into a cohesive and believable final image. The composition involves adjusting lighting, color grading, and integrating various elements to create a seamless and visually stunning result that blends with the live-action footage.

​

Directing:
 

Directing involves overseeing all aspects of a film or video production, including visual effects. The director is responsible for guiding the creative vision and ensuring that the story is effectively conveyed to the audience. In the context of visual effects, the director collaborates closely with the VFX team to achieve the desired look and feel of the visual effects shots, ensuring they align with the overall storytelling and cinematography.

 

Scriptwriting:

​

Scriptwriting involves crafting the screenplay or script for a film, TV series or video project. It outlines the entire story, dialogue, and action of the production. The script also serves as a blueprint for the VFX team, breakdowns, budgeting, to understand the requirements and objectives of the project.
