What is an HTML5 Video File?

The HTML5 video is a new kind of video element, designed to replace a portion of the original object element. This allows the users to watch videos on websites without the need for any plugins. For this, the webmaster has to create HTML5 coding that corresponds to the links where the video can be downloaded. The formats include OGG, WebM, and MP4. Once your webmaster has created the coding, it gets placed into the body tags of the webpage’s HTML coding. This makes the HTML5 video viewable in all the browsers, such as Google Chrome, Internet Explorer, Firefox, and Safari. If you are downloading these browsers for the first time, then make sure to have the latest updates downloaded for them as well. This guarantees that your browser is compatible to read HTML5 coding on all websites.
