==== Video ====

Metadata is particularly useful in video, where information about its contents (such as transcripts of conversations and text descriptions of its scenes) is not directly understandable by a computer, but where an efficient search of the content is desirable. This is particularly useful in video applications such as [[Automatic number-plate recognition|Automatic Number Plate Recognition]] and Vehicle Recognition Identification software, wherein license plate data is saved and used to create reports and alerts.{{Cite web |url=https://www.dhs.gov/sites/default/files/publications/LPRStandards-TN_1012-508.pdf |title=System Assessment and Validation for Emergency Responders (SAVER) |last=Homeland Security |date=October 2012 |access-date=30 January 2018 |archive-date=31 January 2018 |archive-url=https://web.archive.org/web/20180131080908/https://www.dhs.gov/sites/default/files/publications/LPRStandards-TN_1012-508.pdf |url-status=live}} There are 2 sources in which video metadata is derived: (1) operational gathered metadata, that is information about the content produced, such as the type of equipment, software, date, and location; (2) human-authored metadata, to improve search engine visibility, discoverability, audience engagement, and providing advertising opportunities to video publishers.{{cite web |last=Webcase |first=Weblog |title=Examining video file metadata |year=2011 |url=http://veresoftware.com/blog/?p=364 |access-date=25 November 2015 |url-status=live |archive-url=https://web.archive.org/web/20151126114622/http://veresoftware.com/blog/?p=364 |archive-date=26 November 2015}} Avid's MetaSync and Adobe's Bridge are examples of professional video editing software with access to metadata.{{cite web |last=Oak Tree Press |title=Metadata for Video |year=2011 |url=http://veresoftware.com/blog/?p=364 |access-date=25 November 2015 |url-status=live |archive-url=https://web.archive.org/web/20151126114622/http://veresoftware.com/blog/?p=364 |archive-date=26 November 2015}}
