July 2011 1 2 Forward This manual on preserving audiovisual or broadcast archives has been drawn up on the basis of recommendations made by the SNRT and other partners of the MedMem project during their meeting in Alexandria in December 2010 We hope that the manual will be a guide to Medmem’s partners for several years, helping them to: Set up preventative conservation measures Share experiences and good practices Continue with or set up a preservation and digitisation programme Devise tangible arguments to convince their management of the urgent necessity to have such a programme To do this we have written the manual in four parts: The sales pitch: why preserve and digitise archives? First steps: where to begin? How to set up a pilot study? Methods: How to design a preservation plan. How to set it up. The manual is particularly based on the contributions of Jean Verra and Jean-Noël Gouyet at the Ina Sup course “Assessing an AV collection and creating a strategy to preserve and digitise it”. Throughout the manual there are references to various “good practices”, some of which are drawn on the experiences of broadcasters around the Mediterranean. The manual has been written by Camille Martin and Ina’s engineering department, working closely with the MedMem project’s organisers. Ina, Bry-sur-Marne July 2011 3 Contents 1.

  • Making Sure What You See Is What You Get: Digital Video Technology and the Preparation of Teachers of Elementary Science
    de Mesquita, P. B., Dean, R. F., & Young, B. J. (2010). Making sure what you see is what you get: Digital video technology and the preparation of teachers of elementary science. Contemporary Issues in Technology and Teacher Education, 10(3), 275-293. Making Sure What You See is What You Get: Digital Video Technology and the Preparation of Teachers of Elementary Science Paul Bueno de Mesquita University of Rhode Island Ross F. Dean University of Rhode Island Betty J. Young University of Rhode Island Abstract Advances in digital video technology create opportunities for more detailed qualitative analyses of actual teaching practice in science and other subject areas. User-friendly digital cameras and highly developed, flexible video-analysis software programs have made the tasks of video capture, editing, transcription, and subsequent data analysis more convenient, accurate, and reliable than ever before. Although such technological developments offer a myriad of opportunities for advancements in research and training, especially in the area of preservice science teacher education, a number of technical challenges and unforeseen difficulties may arise when relying on video-based methodologies. If unanticipated, these challenges can compromise the overall integrity of research data and detract from training effectiveness. The purpose of this paper is to identify the challenges and opportunities specific to incorporating video technology into the research on preservice science teacher education within the context of relevant literature. Lessons learned from an ongoing longitudinal study of preservice elementary science teachers are discussed, including practical guidelines for use of digital video for research and professional development. The application of digital video technology (DVT) and the use of computer software programs provide opportunities for innovation within the domain of inquiry in science teacher preparation and can greatly enhance the research methodology concerned with preservice teacher instruction.

    MAGNETIC TAPE RECORDINGS AUDIO and VIDEO Cassettes A primer on their use, handling and storage.... By Bernie Adams President - Adams Magnetic Products, Inc 4123 North Little Creek Road PO Box 1217 Utopia, TX 78884 830-966-4210 11/03/96 Revised 07/01/2000 Page 1 of 16 MAGNETIC TAPE RECORDINGS AUDIO and VIDEO Cassettes OVERVIEW The purpose of this article is to give a better understanding of what affects the performance and longevity of audio and video recordings. It deals primarily with the proper handling and storage of audio and video cassettes to safe guard the recordings for future use. However, no matter how carefully a wrong type of tape and especially inferior quality tape may be handled during use or storage the quality of the recording is still going to be compromised. The physical makeup of the inferior tapes or cassettes are such that they will not withstand long-term storage. The proper selection, use, handling and storage of magnetic tape for recording of audio or video in any format is extremely important as we are dealing with the preservation of irreplaceable evidence. Careless selection, improper use, handling, or storage can render the recordings useless for submission as viable evidence. For the purpose of this discussion Audio and Video Magnetic Tape Cassettes will generally be treated the same as they both contain Magnetic Tape of very similar makeups and are manufactured using the same basic processes. Of course differences affecting performance, handling and storage will be addressed separately. To understand the proper handling and storage requirements, it is important to understand what makes up a magnetic tape, its transport mechanism i.e., the cassette, the materials involved and the environmental effects of both physical and electromagnetic elements etc.
