vfx terminologies with examples

TERMINOLOGIES IN

VISUAL EFFECTS

• “Visual Effects" is referring to digital post-production and "special effects" referring to on-set mechanical effects and in-camera optical effects.

• Visual effects involve the integration of live-action footage and generated imagery to create environments which look realistic which is impossible to capture on film.

VISUAL EFFECTS

CATEGORIES OF

VISUAL EFFECTS

• Miniature sets and models, animatronics.

MODELS

• Digital or traditional paintings or photographs which serve as background plates for keyed or rotoscoped elements.

MATTE PAINTINGS

• Keying actors or models through bluescreening and greenscreening.

LIVE-ACTION EFFECTS

• Modeling, computer graphics lighting, texturing, rigging, animating, and rendering computer-generated 3D characters, particle effects, digital sets, backgrounds.

DIGITAL ANIMATION

DIFFERENT TYPES

OFVISUAL EFFECTS

• Is the combining of visual elements from separate sources into single image, often to create the illusion that all those elements are parts of the same scene.• Takes real-life elements with Computer

Generated (CG) Element and putting them together – seeming like they were shot together. 

COMPOSITING

COMPOSITING

COMPOSITING

• Is a technique for mixing two images or frames together in which a color (or a small color range) from one image is removed (or made transparent), revealing another image behind it. • Has two types: Blue screen & Green

screen

CHROMA KEYING

CHROMA KEYING

CHROMA KEYING

• Is an animation technique in which animators trace over live-action film movement, frame by frame, for use in animated films.• Originally, pre-recorded live-action film

images were projected onto a frosted glass panel and re-drawn by an animator.

ROTOSCOPING

• This projection equipment is called a rotoscope, although this device has been replaced by computers in recent years. In the visual effects industry, the term rotoscoping refers to the technique of manually creating a matte for an element on a live-action plate so it may be composited over another background.

ROTOSCOPING

ROTOSCOPING

ROTOSCOPING

• It is the application of computer graphics to create or contribute to images in art, printed media, video games, films, television programs, commercials, and simulators.

COMPUTER GENERATED IMAGERY (CGI)

• The visual scenes may be dynamic or static, and may be two-dimensional (2D), though the term "CGI" is most commonly used to refer to 3D computer graphics used for creating scenes or special effects in films and television.

COMPUTER GENERATED IMAGERY (CGI)

COMPUTER GENERATED IMAGERY (CGI)

COMPUTER GENERATED IMAGERY (CGI)

• Is a painted representation of a landscape, set, or distant location that allows filmmakers to create the illusion of an environment that is non-existent in real life or would otherwise be too expensive or impossible to build or visit.

MATTE PAINTING

MATTE PAINTING

MATTE PAINTING

• This technique is used in virtually all animation systems where simplified user interfaces allows animators to control often complex algorithms.

RIGGING

• Skeletal animation is a technique in computer animation in which a character is represented in two parts: a surface representation used to draw the character (called skin or mesh) and a hierarchical set of interconnected bones (called the skeleton or rig) used to animate the mesh. 

RIGGING

RIGGING

RIGGING

• The term is used loosely to describe several different methods of extracting camera motion information from a motion picture. Sometimes referred to as motion tracking or camera solving, match moving is related to rotoscoping and photogrammetry.

• Motion capture (MOCAP) is an effective 3D animation tool for realistically capturing human motion .
