An overview of the creation of animation in the modern era

History[ edit ] Starting in the late s to the early s, several types of video production equipment that were digital in their internal workings were introduced.

This made it easier to either correct or enhance the video signal, as in the case of a TBC, or to manipulate and add effects to the video, in the case of a DVE unit. The digitized and processed video information was then converted back to standard analog video for output.

Later on in the s, manufacturers of professional video broadcast equipment, such as Bosch through their Fernseh division and Ampex developed prototype digital videotape recorders VTR in their research and development labs. Bosch's machine used a modified 1 inch type B videotape transport, and recorded an early form of CCIR digital video.

Ampex's prototype digital video recorder used a modified 2 inch Quadruplex videotape VTR an Ampex AVR-3but fitted with custom digital video electronics, and a special "octaplex" 8-head headwheel regular analog 2" Quad machines only used 4 heads.

Like standard 2" Quad, the audio on the Ampex prototype digital machine, nicknamed by its developers as "Annie", still recorded the audio in analog as linear tracks on the tape. None of these machines from these manufacturers were ever marketed commercially. Digital video was first introduced commercially in with the Sony D1 format, which recorded an uncompressed standard definition component video signal in digital form.

Component video connections required 3 cables and most television facilities were wired for composite NTSC or PAL video using one cable. Due this incompatibility and also due to the cost of the recorder, D1 was used primarily by large television networks and other component-video capable video studios.

InSony and Ampex co-developed and released the D2 digital videocassette format, which recorded video digitally without compression in ITU format, much like D1.

But D2 had the major difference of encoding the video in composite form to the NTSC standard, thereby only requiring single-cable composite video connections to and from a D2 VCR, making it a perfect fit for the majority of television facilities at the time.

D2 was a successful format in the television broadcast industry throughout the late '80s and the '90s. D2 was also widely used in that era as the master tape format for mastering laserdiscs. PACo could stream unlimited-length video with synchronized sound from a single file with the ".

Audio Video Interleave from Microsoft followed in Initial consumer-level content creation tools were crude, requiring an analog video source to be digitized to a computer-readable format.

While low-quality at first, consumer digital video increased rapidly in quality, first with the introduction of playback standards such as MPEG-1 and MPEG-2 adopted for use in television transmission and DVD mediaand then the introduction of the DV tape format allowing recordings in the format to be transferred direct to digital video files using a FireWire port on an editing computer.

This simplified the process, allowing non-linear editing systems NLE to be deployed cheaply and widely on desktop computers with no external playback or recording equipment needed.

The widespread adoption of digital video and accompanying compression formats has reduced the bandwidth needed for a high-definition video signal with HDV and AVCHDas well as several commercial variants such as DVCPRO -HD, all using less bandwidth than a standard definition analog signal.

These savings have increased the number of channels available on cable television and direct broadcast satellite systems, created opportunities for spectrum reallocation of terrestrial television broadcast frequencies, made tapeless camcorders based on flash memory possible among other innovations and efficiencies.

Overview[ edit ] Digital video comprises a series of orthogonal bitmap digital images displayed in rapid succession at a constant rate. In the context of video these images are called frames.

Since every frame is an orthogonal bitmap digital image it comprises a raster of pixels. If it has a width of W pixels and a height of H pixels it is said that the frame size is WxH.

Pixels have only one property, their color. The color of a pixel is represented by a fixed number of bits. The more bits the more subtle variations of colors can be reproduced. This is called the color depth CD of the video.

An example video can have a duration T of 1 hour seca frame size of x WxH at a color depth of 24 bits and a frame rate of 25fps. This example video has the following properties: The formulas relating those two with all other properties are: The first half contains only the odd-numbered lines of a full frame.

The second half contains only the even-numbered lines. Those halves are referred to individually as fields.The Online Writing Lab (OWL) at Purdue University houses writing resources and instructional material, and we provide these as a free service of the Writing Lab at Purdue.
