The duration in minutes of the individual parts (reels, tapes, rolls) of an audiovisual item.


Purpose: Informs users of the playing time for parts of an audiovisual item.


Relationship: This element is dependent on Media Type. Each media occurrence of the archival materials must have a media type specified to create Running Time: Minutes. Running Time: Minutes works in conjunction with Running Time: Seconds. The Guidance for this element explains the details of this relationship.



Enter the number of minutes for the running time of each part of an audiovisual item. Each part (reel, roll, tape) should be described as a separate media type.

If the running time is more than five minutes, round it off to the nearest minute.

If the running time is less than five minutes, indicate it as minutes and seconds. To do this:

  • enter the number of minutes in Running Time: Minutes
  • enter the number of seconds in Running Time: Seconds.

Do not enter the length as "2.5" minutes, instead enter it as "2" minutes and "30" seconds. (The "30" seconds is entered in Running Time: Seconds.)




[For a two-hour motion picture film.]
