Unreferenced date July 2010 Mouse teeth or herringbone pattern is the term for a distortion arising from deinterlacing video. They occur when two Frame film frames combined for deinterlacing are noticeably different. Similar distortions may also be referred to as tearing or line crawling . This distortion is most noticeable when there is horizontal movement between the two frames, as the lines in the newer frame will be shifted in the direction of motion from the older frame. When the frames are combined a jagged edge mouse teeth will be formed.

DCDi by Faroudja Directional Correlation Deinterlacing is a digital enhancement method developed by Faroudja in 1996. DCDi technology is primarily used for improving the image quality of low Image resolution resolution images. The DCDi algorithm starts by deinterlacing images, using a number of techniques, including Bad Edit Detection , which detects 24 frame s film sources in 30 frame s video streams, converting the stream back to 24 frame s. The DCDi algorithm also employs edge detection to find the moving edges in a scene and adjust the angle of interpolation at each pixel so that the interpolation always follows the edge instead of crossing it. This eliminates staircasing and or jagged edge artifacts. These techniques won an Emmy Award from National Academy of Television Arts and Sciences in 2001. The DCDi technique is often licensed and used in LCD and plasma television sets, as well as DVD and Blu ray players.

unreferenced date June 2009 The field rate of an interlaced video image is twice the effective frame rate , since interlacing draws only half of the image the odd or even numbered lines at a time. For example, a field rate of 60 Hertz will correspond to a 30 frames per second moving picture. A field rate can apply to either a video signal, or to a monitor designed to display that signal without conversion. Theoretically, an interlaced signal could have three or more fields per frame, resulting in a field rate that is a 3x or higher multiple of the frame rate. However no such signal is in common use today. Progressive scan monitors do not have a field rate, however they may still display interlaced video by converting each field into a full frame, a process called deinterlacing . In this case, the monitor s frame rate would then likely match the video signal s field rate. physics stub Category Film and video technology ... more details

As the opponent s punch arrives, the fighter bends the legs quickly and simultaneously shifts the body either slightly right or left. Fighters generally begin the bob and weave to the right, as most opponents strike with their left hand, or jab hand first. The move has been incorporated into aerobic kickboxing classes, performed in a U shaped motion. It is often choreographed into other routines. For example jab, bob and weave, hook.

orphan date June 2009 about the anime programming tool the town in the Palestinian territories Yatta town the pop song Yatta YATTA , Y et A nother T elecide T ool for A nime, is a tool used to IVTC video, usually, but not limited to, anime . It is used by a number of groups to achieve high quality MPEG 4 encodes of anime and other material. It enables the user to perform a series of video cleanup tasks, including but not limited to inverse telecine overriding, freeze frame assistance, and sectioned filter application. The primary focus of YATTA is to perform IVTC i n v erse t ele c ine , which is the act of eliminating combing so called artificial interlacing on the video source caused by the 3 2 pulldown process and lowering the frame rate to that of film. In YATTA s case, this is accomplished in two steps by first aligning telecined fields back into full frames using a current, current, next, next, current ccnnc pattern, then decimating removing the duplicate frame left by the second next match. In addition to pure IVTC, YATTA also allows the combination of IVTC and traditional deinterlacing for sources mixing telecined and truly interlaced material, enabling variable frame rate manipulation to create VFR Matroska video files. The secondary focus is on source improvements through a variety of means. The simplest involves freeze framing to replace bad frames, and moves into more intricate sectioned filtering.

Unreferenced date December 2009 Confusing date February 2009 A flicker fixer or scan doubler is a piece of computer hardware that deinterlacing de interlaces the output video signal. The purpose of a flicker fixer is to adjust a video Signalling telecommunication signal prepared for television TV to the needs of an ordinary cathode ray tube CRT computer display. One example of a computer that was capable of producing an interlaced image is the Commodore International Commodore Amiga . The Amiga s default video mode is PAL or NTSC . NTSC and PAL interlaced screens have two fields called odd and even. The fields switch every 1 60th of a second on NTSC, or 1 50th of a second on PAL, which allows for more higher resolution whilst using a narrower signal Bandwidth signal processing bandwidth than full 50 or 60 frame rate FPS progressive video would require, but it can also produce an alarming jitter ing effect for graphics with high contrast details between fields. This NTSC PAL compatibility gave the Amiga a distinct edge in uses such as television production or computer game gaming , however since the original Amigas were unable to produce vertically high resolutioned displays without flickering this was unsuitable for other, office like uses, where there s a need to work with clear high resolution image often for several hours in order to perform typical tasks. Flicker fixers were devised to remedy this. Flicker fixers sampling signal processing sample the NTSC PAL output from the Amiga and store each scan line from the field currently being displayed in Random access memory RAM while simultaneously outputting the line alternately with the corresponding neighboring lines from the field stored previously. Outputting the image at double scan rate essentially composes a progressive display with all lines from both fields at full vertical refresh rate. This promotes the horizontal frequency of the signal from 15.734 kHz to 31.47 kHz in the NTSC case, numbers for ... more details
Dicdef notability date January 2011 In video , a field is one of the many still images which are displayed sequentially to create the impression of motion on the screen. Two fields comprise one video Film frame frame . When the fields are displayed on a video monitor they are Interlaced video interlaced so that the content of one field will be used on all of the odd numbered lines on the screen and the other field will be displayed on the even lines. Converting fields to a still frame image requires a process called deinterlace deinterlacing , in which the missing lines are duplicated or interpolation interpolated to recreate the information that would have been contained in the discarded field. Since each field contains only half of the information of a full frame, however, deinterlaced images do not have the resolution of a full frame. In order to increase the resolution of video images, therefore, new schemes have been created that capture full frame images for each frame. Video composed of such frames is called progressive scan video. Video shot with a standard video camera format such as S VHS or Mini DV is often interlaced when created, whereas video shot with a film film based camera is almost always progressive. Free to air analog TV was mostly broadcast as interlaced material because the trade off of spatial resolution for frame rate reduced flickering on Cathode ray tube CRT televisions. High definition digital television see HDTV today can be broadcast terrestrially or distributed through cable system in either interlaced 1080i or progressive scan formats 720p or 1080p . There are now some prosumer HDV camcorders that can shoot in progressive scan 720p formats. In video editing, it is crucial to know which of the two odd or even fields is field dominance dominant . Selecting edit points on the wrong field can result in a Wiktionary flash frame flash at each edit point and playing the video fields in reverse order creates a flickering image.
