Video search engine A video search engine is a web-based search engine which crawls the web for video content. Some video search engines parse externally hosted content while others allow content to be uploaded and hosted on their own servers. Some engines also allow users to search by video format type and by length of the clip. Search results are usually accompanied by a thumbnail view of the video. Video search engines are computer programs designed to find videos stored on digital devices, either through Internet servers or in storage units from the same computer. Utility The main use of these search engines is the increasing creation of audiovisual content and the need to manage it properly. Search criterion The search criterion used by each search engine depends on its nature and purpose of the searches.  Metadata is information about facts.  All video formats incorporate their own metadata. Video metadata  Title and Description Filename Tags Frame Analysis
