Understanding Motion Capture: Key Technical Terms
Overview
This article delves into the essential technical terms related to motion capture, covering the stages of Pre-Production, Production, Post-Production, and the realm of New Media.

Pre-Production
Scene
A "scene" in film refers to a numbered script segment, often dissected into long shots, medium shots, and close-ups by the director. A "master scene" is a lengthy script portion under one number, which may initially be filmed in full before breaking it down into close-ups of different characters. In animation, it represents a basic unit of action shot on a single background, contributing to the film’s construction.Script
A film or TV production script provides detailed scene-by-scene instructions, encompassing setting descriptions, actions, dialogue, and camera directions. When a script also includes visual details, it is referred to as a "storyboard."Storyboard
Used extensively in animation and frequently in commercials, a storyboard outlines key positions for each scene with sketches accompanied by dialogue and descriptive notes.---
Production
2D Animation
2D animation creates moving images in a two-dimensional environment. It involves sequencing consecutive frames to simulate motion, typically viewed at 24 frames per second or more.3D Animation
This process involves crafting moving pictures within a three-dimensional digital space, using virtual "cameras" and rendering engines to achieve a perception of motion similar to 2D animation.Character Animation
This art form makes animated figures move distinctively, akin to acting through drawings. Animators must reflect a character's personality and physique through its movements.Computer Animation and Graphics
Computer animation leverages computers to create moving images, both in 2D and 3D. Advanced programs manage movement, shading, and illumination, requiring faster computers for realistic results. In contrast, computer graphics involve charts, diagrams, and drawings generated by computers.Other Animation Techniques
- Effects Animation: Focuses on non-character movements like rain or smoke.- Go-Motion: A variant of stop-motion using rods for realistic blur and movement.
- Rotoscoping: Involves drawing around elements in frames to apply effects, originating from tracing live-action films.
- Virtual Sets: Computer-generated backgrounds used in TV, replacing real sets.

Post-Production
Editing Phases
- Edit: Compiling video, audio, and graphics into a cohesive presentation.- Off-Line Edit: A preliminary draft edit using simpler equipment.
- On-Line Edit: The final professional edit version using high-quality equipment.
Render Farm
A collection of computers working together to tackle the computational tasks of 3D rendering, a critical component of post-production.---
Motion Capture
Mocap
Motion capture records human movement data for use in 3D character animation, applicable to film, TV, and games.Performance Capture
Captures a performance's nuances, differing from basic motion capture by emphasizing the expressiveness of human or animal movements.Visual and Special Effects
Utilize techniques like chroma-keying, compositing, and wire removal, integrating digital data with live-action to create seamless illusions.---
New Media
Definition
"New Media" encompasses various electronic communication forms enabled by computer technology, contrasting with static "old" media. Examples include websites, streaming, email, online communities, and more, often interacting between desktops, laptops, and handheld devices.Through understanding these technical terms, one can gain a clearer insight into the intricate processes behind motion capture and related fields, enriching the production and post-production landscape.
