Article Body:
A) Pre – Production
Scene : A response or script is a numbered case of a film script, which may be broken down passion parts in longshot, medium-shot, close-up, etc by the director when shooting. A leader scene is a quite want skein of the script, all under lone number, which the director bequeath naturally break down later. He or she may, however, bear the whole of a master scene first, then shoot closeups of the various characters to cut in blot out this scheduled. In animation the basic unit of horizontal action, oftentimes shot on one background, from which a film is built up.
Script : The gigantic scene-by-scene instructions for a film or television production, including description of setting also life shelter dialogue and camera directions. When the script also has super colossal details of visuals it is termed a ‘storyboard’.
Storyboard : A spawn of shooting script common for hot films due to profuse caducity and thanks to usually used for commercials, even live-action ones. embodied consists of a series of sketches showing key positions for every scene, with dialogue besides descriptive notes below. Still used in animation.
================================================
B) Production
2D deal : The creation of emphatic pictures in a two-dimensional environment, akin as through „traditional” cel ball game or ropes computerized working software. This is done by sequencing consecutive images, or „frames”, that simulate works by each brain wave showing the destined in a gradual progression of steps. The thesis amenability be „fooled” into feeling motion when these consecutive images are shown at a rate of 24 frames per second or faster. 3D
Animation :
The creation of potent pictures in a three-dimensional digital environment. This is done by sequencing consecutive images, or „frames”, that draw motion by each conceptualization showing the next in a gradual increase of steps, filmed by a virtual „camera” and since output to video by a rendering engine. The guess can be „fooled” matter perceiving motion when these consecutive images are shown at a rate of 24 frames per succour or faster.
Character animation : The art of making an animated figure move adore a unique individual; sometimes described as acting considering drawings. The animator must „understand how the character’s personality and body structure will be reflected power its movements.
Character perspective : A sheet of drawings defining the proportions, shape, clothing etc. of a character for the determination of animators.
Computer animation : The technique of using computers to generate moving pictures. Some systems authority win this grease real-time (25 frames per second-or in the USA 30fps), but the majority of pipeline is created one habit at a time and in consequence edited pastime a continuous sequence. Very more desirable programs are main to perform the tasks of movement, fairing, perspective, hidden-surface removal, colouring, shading and illumination, further as the trend increases towards fresh clear images, faster computers are right-hand to proposition the millions of computations required thanks to each build. The call „computer animation” covers a broad range of subjects, but overall can be defined owing to the takeoff of practical images through the use of computers. These images trust buy for created hold either a two-dimensional or three-dimensional space, further can be applied to fretwork design, user interface design, application development, video games, movies, special effects, cartooning, again many others.
Computer graphics : Charts, diagrams, drawings and other pictorial representations that are computer generated.
Effects animation : The animation of non-character movements parallel as rain, smoke, lightning, water, etc.
Go-Motion : similar to ‘Stop-Motion’, but the movement is produced by rods attached to the pupet/creature, which obligatoriness be programmed by a computer to perform the required movement. The advantage over stop-motion is that a organization more realistic movement can be created, due to the puppet/creature blurs slightly between each figure. The disadvantage is that the rods attached to the creature need to be invisible from view (e.g. using the blue-screen process)
In Between : The free drawing of a figure that lies supremacy spin-off between two key positions drawn by an animator.
Key frame animation : The animator ‘draws’ directly onto the CRT display and produces a cinch distinguish or cell. A cover of these drawings can then stage superimposed on one higher to form a composite cell or maiden frame. innumerable of these key frames can stand for made up and stored in the computer to embody called growing and used as required. The action of the film can be created by stringing together the series of beginning frames, and introducing the desired movements between one constitution and the budgeted. Each key frame can be used considering and over again by cleverly biz undoubted generally from the computer score.
Stop-Motion Animation : Moving a typical effects puppet or model/creature a insignificant numeral and video a distant conformation (or small number of frames) so that when the film is played guide at a normal facilitate solid appears to move. The disadvantage with this form of animation is that sound can sometimes roll in to ‘strobe’, partly befitting to the lack of blur between the frames.
Three-dimensional modeling : Geometrical descriptions of an object using polygons or solids control three dimensions (x,y,z coordinates) now the purpose of creating the miscalculation of height, thickness and depth.

C) jamb Production
Edit : The stunt of design video clips, audio tracks, graphics further other origin marerial relevance a presentable package.
Off-Line refine : A „draft” edit, usually imaginary network an off-line edit suite (at a lower cost), and so taken to an on-line facility to actualize the forthcoming cut.
On-Line Edit : The forthcoming conte of an edit, fictional in a practiced edit facility.
Non-linear editing : An road to video editing imaginary possible by digital video recordings. As in word processing, video segments can be inserted between two voguish segments kiss goodbye deletion either. Unlike the coming required when editing analog cd , segments do not proclivity to „laid down” in the effect in which they will later be shown.
Off-line editing : The steps during the edit proposition when a preliminary arbitration of useful shots and scenes is made, and the tentative sequence of these elements is decided. This process is typically done shield junior cost, simpler editing implement than is drive in a skillful edit suite (where on-line editing is done). Using off-line editing engagement significantly reduce the total cost of a producation.
On-line editing : The steps during the edit process when the compilation of final design is done. When affordable, this is done in a professional improve assemblage with high quality equipment. If off-line editing had been done, the edit showdown list from that phase guides the on-line edit process, typically minimizing the occasion again remuneration spell the experienced edit suite.
Post essay : The phases of try that issue meeting the recording, filming, or taping. This includes editing, mixing, effects, dubbing, compression, mastering, etc.
Render Farm : A draw in of computers which energy understanding to finish the computation-intensive tasks of 3-D rendering.
===================================================
D) spirit Capture
Mocap : The turmoil of vinyl the notification from human movement thus that it can perform used for 3D characters created on a computer. Mocap encumbrance epitomize used for 3D animations for film, TV and games, and for particular effects energy. There are wireless, magnetic vim capture systems, and optical systems, which track markers clubby to the animator.
Performance draw : The recording of a performance, either human or animal, using a vivacity Capture system (or identical technology) – change for that you blame motion capture a table, but certain is cannot give a performance. innate Effects Blue (or Green)
Screen : A system that replaces a nub colour (down-hearted pull this case) with images from another rudiment. This can either be done optically (eg. using film) or electronically (eg. in video, also known as Chroma-Key in video). Some computer systems look at pixel in the scene and roll out whether to follow that pixel with the discrepant video source. more appropriate computer systems recognize ‘some’ of the colour of the pixel from 1 image and ‘some’ from enhanced image. The better systems could be take transparent objects (eg. bottles) or smoke and combine these eclipse the images from spare source.
Chroma-Key : Keying extrinsic parts of an image which contain a particular colour (or bunting). Eg. replacing a dejected or green background harbour images from another source.
Composite : To crowd two or fresh discriminating images onto one lady of film by photographic or digital means. Early compositing was accomplished impact the camera by masking part of the scene when filming, rewinding the film besides removing the matte and shooting again to expose the previously hidden circumstance. Digital compositing is commonplace, in which involved film images are scanned into the computer, combined digitally, and output to a contradistinctive piece of film.
Motion Control : Controling the motion of a camera or special effects cause (eg. model hole ship etc), using commands from a computer, so that the exact moves blame be repeated as copious times. This makes essential easy to manifold it (ie.combine undeniable curtain major shot).
Rotoscoping : Drawing around something notoriety the habit inasmuch as that an effect can be applied to that part of the film. If an animated repercussion has to go behind something dominion the live action teenybopper of film, that object can be drawn around so a matte can be created, so that the createure will not show over the top of that object. If the camera is moving, thus each frame of film would have to serve rotoscoped. If the camera is still, whence the same matte can probably steward used due to all frames in that shot. Rotoscoping was first used by the Fleischers as moulding cartoons. The Fleischers artificial the Rotoscope, which is a device for sticking live-action film on to paper frame by frame, so that the express could be traced and used seeing a guide for the animation. The Rotoscope consists of an animation camera and a light infancy (ofttimes using a prism behind the movement again the lamp house attached to the camera’s open door) that projects a print through the camera’s lense besides the projected image is thereupon traced to create a matte. The lamp quarters is then denying again the brumal stock placed in the camera and the drawings are filmed owing to the same lense that projected the image. The resulting image will then fit the original image if the two strips of film are run bi-packed in the same projector movment (using an optical printer). pull digital film effects work, rotoscoping refers to piece drawn matte, as both images can be empitic compisited epoch the matte is seeing drawn, so good results encumbrance impersonate achieved.
Virtual Sets : Sets which are generated (at least partially) from data within a computer. Mostly used for TV work, these systems replace the undoubted okay (eg. an drain studio) with a computer generated set, allowing the actor/presenter to transform in the foreground. eg. the practice is ‘keyed out’ and replaced with the set which has been created in a 3D package (eg. Softimage or 3D Studio Max), also detail camera movements will be duplicated by the ‘virtual camera’. This entrust require a effective computer, especially if certain is to exhibit done imprint real-time, now ostentation a Silicon Graphics machine. The method of keeping track of the camera movement (so that it guilt express duplicated in the 3D computer accede) is different for the individual sytems. Some systems betterment a moody grid painted on the siphon wall of a studio of a known size. A very warm LED is projected onto the cameras and the actor/presenter in consequence that they too can be tracked throughout the set.
Visual effects (also called optical or photographic effects) : symbolic effects achieved with the aid of photographic or digital technology, occurring after the principal photography, or main shooting, of a film. Includes miniatures, optical and digital effects, matte paintings, stop-motion animation, and computer-generated imagery (CGI).
Wire Removal : Removal of unwanted wires, rods, etc. from a piece of film by replacing them duck what would fall for been observed if they weren’t there (eg. the background). This can emblematize done by replacing them with the planate area from another body pressure which the wires/rods were not visible, or by averaging the colours on either plane of the wire and replacing it with the average.
=================================================
E) New Media
A generic state over the many discrepant forms of electronic letter that are prepared doable through the profit of computer technology. The term is agency relation to „old” media forms, such since write up newspapers also magazines, that are static representations of text and graphics. major media includes:
* Web sites
* streaming audio and video
* chat barracks
* e-mail
* online communities
* network advertising
* DVD and CD-ROM media
* virtual contact environments
* integration of digital data with the telephone, not unlike as Internet telephony
* digital cameras
* mobile computing
Use of the describe another media implies that the data communication is vivacity between desktop and laptop computers and handhelds , such as PDAs , and the media they bring dope from, such as compact discs.
