Metadata – As pertaining to digitisation workMetadata

Metadata is data about other data. It helps us manage information about how and when physical media has been digitized.

Metadata can be an independent file or embedded in other files.

Whilst metadata has many other purposes and meanings we are focusing only on the meaning relevant to the digitisation & archival of physical media.

Types of Metadata

  • Embedded in video files
  • Embedded in audio files
  • Embedded in picture files
  • Excel / csv document

Video Metadata

  • Most video files have metadata embedded with them containing details of the file
  • We generally cannot add additional metadata to video files
  • Standard video metadata includes items such as frame size, frame rate, timecode information, track layout, etc

Video Metadata Example:

Audio Metadata

  • Standard audio files requested from clients engaging us for digitisation are:
    • WAV (standard / normal)
    • WAV (BWF – Broadcast Wav File)
    • MP3
  • (standard) wav files only contain basic information about the file: Bit depth, frequency, etc. No additional information can be added to a standard wav file

WAV Metadata Example:
