  • ASPECT RATIO Aspect Ratios Are One of the More Confusing Parts of Video
    ASPECT RATIO Aspect ratios are one of the more confusing parts of video, although they used to be simple. That's because television and movie content was all about the same size, 4:3 (also known as 1.33:1, meaning that the picture is 1.33 times as long as it is high). The Academy Standard before 1952 was 1.37:1, so there was virtually no problem showing movies on TV. However, as TV began to cut into Hollywood's take at the theater, the quest was on to differentiate theater offerings in ways that could not be seen on TV. Thus, innovations such as widescreen film, Technicolor, and even 3-D were born. Widescreen film was one of the innovations that survived and has since dominated the cinema. Today, you tend to find films in one of two widescreen aspect ratios: 1. Academy Standard (or "Flat"), which has an aspect ratio of 1.85:1 2. Anamorphic Scope (or "Scope"), which has an aspect ratio of 2.35:1. Scope is also called Panavision or CinemaScope. HDTV is specified at a 16:9, or 1.78:1, aspect ratio.If your television isn't widescreen and you want to watch a widescreen film, you have a problem. The most common approach in the past has been what's called Pan and Scan. For each frame o a film, a decision is made as to what constitutes the action area. That part of the film frame is retained, and the rest is lost.. This can often leave out the best parts of a picture.

  • Screen Size Selection
    Screen Size Selection One of the most important decisions in screen selection is to determine the correct size of screen based upon the dimensions of the audience area and the projection format(s) to be used. In some situations, these two questions yield the same answer; in • Ceiling Height—The bottom of the screen should be approximately others they do not and compromises must be made. Here are the key 40–48" above the floor in a room with a level floor and several rows considerations— of seats. In rooms with theatre seating or only one or two rows, • Audience Area—In determining the correct screen size in relation to such as a home theatre, the bottom of the screen should usually be the audience area, the goal is to make the screen large enough so 24–36" above the floor. Try to make sure that the lower part of the those in the rear of the audience area can read the subject matter screen will be visible from all seats. Extra drop may be required to easily, but not so large that those in the front of the audience area position the screen at a comfortable viewing level in a room with a have difficulty seeing the full width of the projected image. high ceiling. • Height—Use the following formulas for calculating screen height for • Projection Format—Once you have determined the correct size of maximum legibility.

    MARK FREEMAN Encyclopedia of Science, Technology and Society http://www.factsonfile.com/newfacts/FactsDetail.asp?PageValue=B ooks&SIDText=0816031231&LeftID=0 WIDESCREEN The scale of motion picture projection depends upon the inter- relationship of several factors: the size and aspect ratio of the screen; the gauge of the film; the type of lenses used for filming and projection; and the number of synchronized projectors used. These choices are in turn determined by engineering, marketing and aesthetic considerations. Aspect ratio is the width of the screen divided by the height. The classic standard aspect ratio was expressed as 1.33:1. Today most movies are screened as 1.85:1 or 2.35:1 (widescreen). Films shot in these ratios are cropped for television, which retains the classic ratio of 1.33:1. This cropping is accomplished either by removing a third of the image at the sides of the frame, or by "panning and scanning." In this process a technician determines which portion of a given frame should be included. "Letterboxing" creates a band of black above and below the televised film image. This allows the composition as originally photographed to be screened in video. The larger the film negative, the more resolution. Large film gauges allow greater resolution over a given size of projected image. In the 1890's film sizes varied from 12mm to as many as 80mm, before accepting Edison's 35mm standard. Today films continue to be screened in a variety of guages including Super 8mm, 16mm and Super 16mm, 35mm, 70mm and IMAX. Cinema and the fairground share a common history in the search for technologically based spectacles and attractions.

Leveämpään päin. Eri kuvasuhteet ja niiden käyttö fiktiivisessä elokuvassa Opinnäytetyö. Kemi-Tornion ammattikorkeakoulu. Kulttuuriala. Viestinnän koulutus- ohjelma. Sivuja 34. Liitteet 1. Opinnäytetyössäni käsittelen fiktiivisien elokuvien kuvasuhteita ja niihin liittyviä tekni- siä ja taiteellisia ratkaisuja. Tarkoitukseni oli kuvata lyhytelokuva siten, että sen kuvan lopullinen rajaus ja kuvasuhde määriteltäisiin jälkituotantovaiheessa. Tavoitteeni on selvittää, toimiiko ja miksi elokuva näin jotenkin paremmin sekä mikä vaikutus ku- vasuhteella on elokuvan eri tuotantovaiheisiin. Käsittelen opinnäytetyöni aluksi elokuvan kuvasuhteiden historiaa ja teknistä toteutusta 35 millimetrin filmillä sekä videolla ja digitaalisella elokuvalla. Lisäksi tutkin ku- vasuhteiden taiteellista puolta eli miten kuvan sommittelu eroaa eri kuvasuhteilla. Opinnäytetyöni kirjallisessa osassa paneudun siihen, mikä merkitys valitulla kuvasuh- teella on elokuvan toteutukseen ja lopulliseen visuaaliseen ilmeeseen. Teososa on lyhyt- elokuva Mitä mä haluan, jossa toimin kuvaajana. Valitulla kuvasuhteella on suuri merkitys elokuvan tuotantoon. Sen lisäksi, että se hyvin pitkälti määrittää elokuvan visuaalisen ilmeen lisäksi paljon kuvauksissa käytettävää tekniikkaa. Eri kuvasuhteet tarjoavat sommitteluun

In the intervening years most people have probably forgotten the hype that attended the film’s release. The digital production, distribution, and screening of Attack of the Clones was heralded in the popular media as marking a watershed moment in the history of film, “a milestone of cinema technology” along the lines of The Jazz Singer (McKernan).

Video and still picture frames have a frame aspect ratio, and the pixels that make up the frame have a pixel aspect ratio. You record video for television in either a 4:3 or 16:9 frame aspect ratio. Additionally, different video recording standards use different pixel aspect ratios. You set the frame and pixel aspect ratios for a Premiere Pro project when you create it. Once these ratios are set, you cannot change them for that project. You can, however, use assets created with different aspect ratios in that project. Premiere Pro automatically tries to compensate for the pixel aspect ratio of source files. If an asset still appears distorted, you can manually specify its pixel aspect ratio. Reconcile pixel aspect ratios before reconciling frame aspect ratios, because an incorrect frame aspect ratios can result from a misinterpreted pixel aspect ratio. Frame aspect ratio Frame aspect ratio describes the ratio of width to height in the dimensions of an image. For example, DV NTSC has a frame aspect ratio of 4:3 (or 4.0 width by 3.0 height).

  • Wasson, “The Networked Screen” - 69
    WASSON, “THE NETWORKED SCREEN” - 69 THE NETWORKED SCREEN: MOVING IMAGES, MATERIALITY, AND THE AESTHETICS OF SIZE Haidee Wasson However conceived—as institution, experience, or aesthetic—the past and the present of moving images are unthinkable without screens. Large or small, comprised of cloth or liquid crystals, screens provide a primary interface between the forms that constitute visual culture and its inhabitants. Animated by celluloid, electronic, and digital sources, these interfaces broker the increasing presence of moving images in private and public life: museums and galleries, stock exchanges, airplane seats, subways, banks, food courts, record stores, gas stations, office desks, and even the palm of one’s hand. Some screens emit light and some reflect it; some are stationary and others mobile. Variations abound. But, one thing is certain. Contemporary culture is host to more screens in more places.1 In film studies, the proliferation of images and screens has largely been addressed by tending to the ways in which cinema is more malleable than WASSON, “THE NETWORKED SCREEN” - 70 previously understood, appearing everywhere, transforming across varied media and sites of consumption. The dominant metaphors used to discuss the multiplication of screens and the images that fill them have been metaphors of variability, ephemerality, dematerialization, or cross-platform compatibility, wherein screens are reconceptualized as readily collapsible, shrinking and expanding windows. Scholars use terms like “content,” “morphing,” and “themed

  • Anamorphic Now You Use the Entire Image Capture Area, Without Letterboxing, and the Result Is a Picture with More Pixels, More Resolution, and Less Noise
    Anamorphic Now you use the entire image capture area, without letterboxing, and the result is a picture with more pixels, more resolution, and less noise . This was one of the original reasons why anamorphic (’Scope) was developed in the first place in the 1950s—to use more film negative area with less grain and more resolution. Peter Märtin of Vantage Film, makers of Hawk Anamorphic lenses, explains. “Anamorphic lenses use cylindrical elements to squeeze the image in one axis only—the width, not the height. That means an anamorphic lens has different focal lengths: the horizontal part of the image is the wider focal length and the ver- tical is the longer focal length. Also, the lens has two nodal points. (The nodal point is where all light beams converge when going through the lens.) One nodal point is for the horizontal part of the light rays, and the other one is for the vertical. Essentially, the lens records the image in a sort of three-dimensional way. “It’s similar to looking at a landscape with one eye closed. If you hold up your hand and move it closer to you, your hand will cover- ing more of the background. Move side to side, and you reveal dif- ferent perspectives behind your hand. You get information about Apocalypse Now, Blade Runner, Close Encounters of the Third Kind, the three-dimensionality of the room. Anamorphic lenses do Bridge on the River Kwai, Evita — if you were enthralled by the look something similar: providing the two dimensional sensor a part of of these classic ’Scope films, you may be considering anamorphic the three-dimensional information.
