The MIME type denotes the container format of the file, and the container format defines the interpretation of the codec string. The 'type' attribute specifies the MIME type and possibly a list of codecs, which helps the browser to determine whether it can decode the file without beginning to download it. Alternatively, the JavaScript canPlayType() function can be used to achieve the same. Using any number of elements, as shown below, the browser will choose automatically which file to download. The 'video' element supports fallback through specification of multiple sources. The browser in question 'knows best' what formats it can use.

For other features, browser sniffing is used sometimes, which may be error-prone: any web developer's knowledge of browsers will inevitably be incomplete or not up-to-date. Video format support varies among browsers (see below), so a web page can provide video in multiple formats. Its purpose is to be representative of the video. The optional 'poster' attribute specifies an image to show in the video's place before playback is started. Alternatively, playback can be controlled with JavaScript, which the web designer can use to create a custom user interface. The 'controls' attribute enables the browser's own user interface for controlling playback. This is fallback content to display for user agents that do not support the video tag.

The element was proposed by Opera Software in February 2007. The element started being discussed by the WHATWG in October 2006. As of 2020, HTML5 video is the only widely supported video playback technology in modern browsers, with the Flash plugin being phased out. HTML5 video is intended by its creators to become the new standard way to show video on the web, instead of the previous de facto standard of using the proprietary Adobe Flash plugin, though early adoption was hampered by lack of agreement as to which video coding formats and audio coding formats should be supported in web browsers.

The HTML5 specification introduced the video element for the purpose of playing videos, partially replacing the object element.
