Poster Attribute
One additional attribute available for the <video> element is the poster attribute. The
poster attribute allows us to specify an image, in the form of a URL, to be shown before
a video is played. The example below uses a screen capture from the video as the poster for
the Earth video.

Video Fallbacks
As with the <audio> element, video fallbacks are also necessary. The same markup
format, with multiple <source> elements for each file type and a plain text fallback, also
applies within the <video> element.
