  • Transcoding Digital Video

    ‘Digitisation’ is a process in which analogue materials become digital, while ‘transcoding’ is the shift from one digital format to another digital format. This brief paper looks at some common situations which call for transcoding, such as when ‘migrating’ data to new formats in order to avoid obsolescence.

  • Planning a Video Digitisation Project

    The digitisation of an existing video collection has many potential benefits; newly digitised materials offer opportunities to reach new users and to engage with new and existing users in new ways. Digitisation may also prove to be the only viable way to make our vulnerable video materials available to generations of future users. The complexities of achieving a successfully digitised and fully accessible video collection can be considerable but through careful preparation, the task can be broken down into manageable stages.

Audio advice tagged 'digital preservation'

  • Uncompressed Audio File Formats

    This document summarises the main features of uncompressed audio file types, including WAV, AIFF and Broadcast WAV (BWF). It gives an overview of these ‘raw’ formats, and a simple explanation of the common options they will offer the user when creating or working with digital audio. It also looks at lossless compression tools for subsequently reducing the size of these files which will allow reconstruction of their original audio data sonically unaltered. Several sections include links to further resources covering specific relevant topics in more detail, so this is a good place to start if you want to learn more about any of these formats.

  • Copyright and Other Rights for Creating Time-based Media Resources

    This advice document provides some basic information on rights issues associated with creating time-based digital media resources. By time-based we mean resources that change over time - including spoken audio, music, animation, and video - as opposed to still images or screen shots, which do not change over time. Rights issues include copyright, recording rights, moral rights and performance rights.

  • Metadata Standards and Interoperability

    This advice document aims to provide a comprehensive look at the various choices the developer of multimedia collections has in terms of metadata standards and the principles behind using them. It attempts to provide a synopsis of general metadata trends, a) in usage for audio, moving and still image format types; b) in specific areas of practice such as museums, archives, libraries and education; and, c) in various activities and tasks such as preservation, interoperability and resource discovery. For an overview of the whole series of papers, and an introduction to the metadata issues discussed here, please see An Introduction to Metadata.

  • Systems for Managing Digital Media Collections

    Everyone's collection and context is unique, so your choice of a system (or systems) for managing your digital media will require a careful assessment of your needs and resources and an evaluation of the available options. This paper provides an overview of a number of different approaches to media management: from some very cheap and 'low-tech' approaches to much more complex and specialised solutions.

  • Audiovisual Signal Types and Interconnects

    Over the decades various technical standards have been adopted for analogue and then for digital video and audio. As the popularity of systems declined they were generally replaced by improved technologies, making many system configurations entirely obsolete. Obsolete interconnects can be difficult to use in conjunction with modern equipment.

    This paper looks at the nature of audio and video signals and then surveys significant historical interconnects (such as RCA) and contemporary, digital equivalents (such as SDI and SPDIF).

    Any method of transferring digital data, such as USB (Universal Serial Bus) can potentially be used to transfer digital audiovisual files, but such technologies are not primarily associated with audio video signal data and so are not discussed here.

  • An Introduction to Digital Preservation

    Digital preservation aims to ensure that a digital collection remains usable, regardless of the inevitable changes in technology the future will bring. Without the appropriate preservation methods in place a digital collection can easily become inaccessible and so useless in just a few years. This paper discusses the preservation of digital output and the associated metadata.

  • Digitising Analogue Video Recordings

    Over the past fifty years the videotape has grown from an obscure television production tool into a vibrant and vital social document. But videotape has proved to be a fragile long-term medium and its contents are at risk. This risk can only be mitigated through careful planning. This workshop will investigate the challenges associated with the preservation of videotapes. Through practical exercises, we will look at how digitising materials to archival standards can both safeguard and help develop a collection. We will also look at the challenge of creating a sustainable digital collection. Quality assurance procedures and best practice will be referred to throughout.
