  1. Digital video material stored on magnetic videotape is considered to be at high-risk of loss or degradation.

    1. Polyester base film used in videotape is considered very stable.

    2. Other components of the videotape, including the binder, are considerably less stable and are more likely to be the cause of degradation.

    3. Format obsolesce, including lack of well-functioning playback equipment poses an equal or even greater risk than degradation, even with higher quality formats such as Digital Betacam

  2. Digital video material stored on magnetic tape should be appraised or re-appraised to determine the nature and signficance significance of video elements contained on the tape and whether the video elements have sufficient archival value to justify reformatting and long-term preservation as digital video files.
