Visual Effects

• Visual effects are the various processes by which
  imagery is created and/or manipulated outside the
  context of a live action shot.
• 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 using computer generated
  imagery has recently become accessible to the
  independent filmmaker with the introduction of
  affordable and user friendly animation and composi
  ting software.
• VFX can be categorize into Compositing, Matte
  Painting, Animation, Lighting, Texture, Rigging.

CGI-Computer Generated Imagery

• 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.
• 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 graphics software is used to make
  computer-generated imagery for films,
  professional-grade films, games, and fine art
  from their home computers.

Rotoscoping

• Rotoscoping 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.
• 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  although this device has been replaced by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.

Compositing

• It 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
• Compositing is taking real-life elements with
  Computer Generated (CG) Element and putting them
  together - so they seem like they were shot
  together. 
•  Live-action shooting for compositing is
  variously called "chroma key", "blue screen",
  "green screen" and other names. Today, most,
  though not all, compositing is achieved
  through digital image manipulation.

Matte Painting

• A matte painting is a painted representation of a
  landscape, set, or distant location that allows
  filmmakers to create the illusion of an
  environment that is nonexistent in real life or
  would otherwise be too expensive or impossible to
  build or visit.
• Historically, matte painters and film technicians
  have used various techniques to combine a
  matte-painted image with live-action footage. At
  its best, depending on the skill levels of the
  artists and technicians, the effect is "seamless"
  and creates environments that would otherwise be
  impossible to film.
• In the scenes the painting part is static and
  movements are integrated on it.

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. While this technique is often used to
  animate humans or more generally for organic
  modeling.
• This technique is used in virtually all animation
  systems where simplified user interfaces allows
  animators to control often complex algorithms
  .However, the intention of the technique is never
  to imitate real anatomy or physical processes,
  but only to control the deformation of the mesh
  data.

Motion Capturing

• Motion capture (MOCAP) is an effective 3D
  animation tool for realistically capturing human
  motion .
• In cinematography, match moving is a cinematic
  technique that allows the insertion of computer
  graphics into live-action footage with correct
  position, scale, orientation, and motion relative
  to the photographed objects in the shot.
• 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.
