    185 For presentation July 8, 1971, NATIONAL CABLE TELEVISION ASSOCIATION, Washington, D. C. TELECINE SYSTEMS FOR THE CATV ORIGINATION CENTER by Kenneth K. Kaylor Phil ips Broadcast Equipment Corp. Although 11 1 ive'' programming is considered a necessary part of the program origination services of a community-oriented CATV system, tele- cine facilities will hold the key to success or failure of such an operation from an economic standpoint. The word 11 tele-cine11 was developed during the early days of television broadcasting to define those facil i- ties devoted to the video reproduction of the various film media. Since the original commercial telecine television camera was an 11 iconoscope11 camera which had a very large sensitive surface (about 11 11 3 x 4 ), a film projector was focused onto the sensor by using a standard projection lens as shown in Fig. 1. This technique was quite simple and optical alignment was very easy. E1 im i nat i ng the 11 Shutte r Bar" effect In the case of motion picture film, the theatre projector had to be modified in order to prevent a "shutter bar" effect caused by the 186 difference in frame rates between television and motion picture stan­ dards. Standard sound motion picture film operates at 24 frames per second while the U. S. standard for television scanning is 30 frames per second. The intermittent mechanism had to be modified so that the 1ength of time between "pu 11 -downs" a 1 te rnates between 1/20 and 1/30 second. The average of these two fractions is 1/24 second, or the time demanded by the standard 24-frame-per-second motion picture projection rate.

  • Aspects of Television Temporality
    Aspects of Television Temporality By Andrzej Gwóźdź Fall 1999 Issue of KINEMA ON SOME ASPECTS OF TELEVISION TEMPORALITY If there is a film that makes the way of existence of its images the object of its discourse, then Cinema Paradiso (Nuovo Cinema Paradiso, by Giuseppe Tornatore, France/Italy, 1989) undoubtedly is that film. It is just here that in an almost demonstrative way the duality of a film iconosphere is shown: a pictorial passage on a film reel on the one hand, and immateriality of die luminous screen phantom on the other, a”film-reel” and a ”film-projection.”(1) It is here that the cinema shows its ontology as a mechanism of difference between materiality of a fundamental cinematographic apparatus and immateriality of a cinematic mechanism that actually results in the source of the cinema. If we were to look for a similar justification for the ontology of television, we would surely have to locate it within the ”time of expression,” that is, temporality immanent to a television image on which the ”time of contents” (2) of a programme structure of television is founded. Since theoreticians of the media agree that it is just time that is ”the major category of television,” that ”time is television’s basis, its principle of strutcturation, as well as its persistent reference”(3); that ”the attitude towards television should be basically derived from temporality”(4); that, finally, ”the essence of the [television] screen is [...] its permanent readiness to experience time.(5)” No matter what stratification of the time of television (television time) is suggested by particular writers, they usually agree on the fundamental ontological premise of television temporality.

  • Simulation of Film Media in Motion Picture Production
    Simulation of film media in motion picture production using a digital still camera Arne M. Bakke, Jon Y. Hardeberg and Steffen Paul Gjøvik University College, P.O. Box 191, N-2802 Gjøvik, Norway ABSTRACT The introduction of digital intermediate workflow in movie production has made visualization of the final image on the film set increasingly important. Images that have been color corrected on the set can also serve as a basis for color grading in the laboratory. In this paper we suggest and evaluate an approach that has been used to simulate the appearance of different film stocks. The GretagMacbeth Digital ColorChecker was captured using both a Canon EOS 20D camera as well as an analog film camera. The film was scanned using an Arri film scanner. The images of the color chart were then used to perform a colorimetric characterization of these devices using models based on polynomial regression. By using the reverse model of the digital camera and the forward model of the analog film chain, the output of the film scanner was simulated. We also constructed a direct transformation using regression on the RGB values of the two devices. A different color chart was then used as a test set to evaluate the accuracy of the transformations, where the indirect model was found to provide the required performance for our purpose without compromising the flexibility of having an independent profile for each device. 1. INTRODUCTION AND BACKGROUND The post-production work on a movie is typically carried out on digital representations of the movie frames. The use of digital technology has brought unique possibilities in all aspects of the post-production of a movie (editing, color grading, visual effects) to the creative community of filmmakers.

FILM, RELAY, AND SYSTEM: A SYSTEMS THEORY APPROACH TO CINEMA by Thomas Schur A Dissertation Submitted in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy in English at The University of Wisconsin-Milwaukee August 2013 ABSTRACT FILM, RELAY, AND SYSTEM: A SYSTEMS THEORY APPROACH TO CINEMA by Thomas Schur The University of Wisconsin-Milwaukee, 2013 Under the Supervision of Professor Tasha Oren Film theory is replete with references to systems, yet no theory has emerged to provide a cohesive explanation of how cinema, as both technology and institution, operates as a relay system. Interdisciplinary in nature, my dissertation proposes a systems theory of cinema deriving largely from the work of social scientist Niklas Luhmann. Systems theory is especially productive for the ways that it intervenes at crucial sites of conflict and irresolution within film studies. With its emphasis on nonhuman agencies, systems theory calls for reappraisal of the significance of the human to the cinema apparatus—a significance long assumed to be simply a given.

  • An Alternative Green Screen Keying Method for Film Visual Effects
    The International Journal of Multimedia & Its Applications (IJMA) Vol.7, No.2, April 2015 AN ALTERNATIVE GREEN SCREEN KEYING METHOD FOR FILM VISUAL EFFECTS Jin Zhi Department of Creative Professions & Digital Arts, University of Greenwich, United Kingdom ABSTRACT This study focuses on a green screen keying method developed especially for film visual effects. There are a series of ways of using existing tools for creating mattes from green or blue screen plates. However, it is still a time-consuming process, and the results vary especially when it comes to retaining tiny details, such as hair and fur. This paper introduces an alternative concept and method for retaining edge details of characters on a green screen plate, also, a number of connected mathematical equations are explored. At the end of this study, a simplified process of applying this method in real productions is also tested. KEYWORDS Digital Compositing, Green Screen Keying, Visual Effects 1. I NTRODUCTION The green / blue screen keying technique has been used frequently in many fields for removing a background from a subject, this technique also is called chroma keying in the visual effects industry. The chroma keying technique was used for the first time in a feature film in 1933 [Richard 1994]. A further development of properly using the chroma keying process for creating a traveling matte [1] was in the film, entitled ‘The Thief of Bagdad ’ in 1940 [2]. In the current digital era, because digital camera sensors are most sensitive to green color [Bryce 1976], the green screen is used more than other colors on set.
