*From [http://www.ahds.ac.uk/preservation/video-preservation-handbook.pdf Arts and Humanities Data Service Preservation Handbook: Moving Image, Gareth Night, 2005]: "For preservation purposes, the significant properties of digital video are the video length (e.g. 90 minutes, 20 seconds), frames per second (25 for PAL, 30 for NTSC), video dimensions (e.g. 720 pixels x 576 pixels), bit-rate (kbps), associated metadata, and file size. If audio is also provided, the audio bit-rate (kbps), frequency (kHz), and number of channels." (p.7)
