Visual Effect (VFX)
All our dreams can come true
if we have the courage to pursue them
Visual effects are the processes by which imagery is created and/or manipulated outside the context of a live action shot. It 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 compositing software. Visual scenes may be dynamic or static, and may be two-dimensional 2D, or 3D computer graphics used for creating scenes or special effects in films and television.
VFX can be categorized into: Rotoscoping, Compositing, Matte Painting.
Roto Scoping
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. 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.
Matte Painting
A matte painting is a painted representation of a landscape, set, or distant location that allows film-makers 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.
