Visual effects (VFX) are the processes by which imagery is created and/or manipulated outside the context of live action shooting. This includes creating things that couldn’t be filmed practically, like fantastical creatures or massive explosions.
Key Characteristics / Core Concepts
- Digital Manipulation: VFX heavily relies on digital software and hardware to create and composite images.
- Compositing: Combining multiple images or elements to create a single, seamless shot.
- 3D Modeling and Animation: Building three-dimensional models of objects and characters, and animating them to create movement.
- Simulation: Creating realistic simulations of physical phenomena like fire, water, or smoke.
- Rotoscoping: Manually outlining and isolating sections of live footage to be replaced or enhanced.
How It Works / Its Function
VFX artists use specialized software to create or alter visual elements within a scene. This can involve anything from subtle enhancements to completely creating new environments and characters. The process often starts with pre-visualization, planning the shots and effects, followed by filming, and then the extensive post-production work.
Examples
- The realistic depiction of dragons in the Game of Thrones series.
- The digitally created environments and characters in Marvel Cinematic Universe films.
- Removing unwanted objects or people from a scene in a film using digital cleanup.
Why is it Important? / Significance
VFX significantly expands the creative possibilities in filmmaking and other media. It allows filmmakers to bring imaginative stories to life, creating visuals that would be impossible or too expensive to achieve through practical effects alone. The impact of VFX extends to video games, television, and advertising.
