HTML5 is the next major revision of HTML (Hypertext Markup Language), the core markup language of the World Wide Web. The Web Hypertext Application Technology Working Group (WHATWG) started work on the specification in June 2004 under the name Web Applications 1.0. As of October 2009, the specification is in the "Last Call" state at the WHATWG.
HTML5 is the proposed next standard for HTML 4.01, XHTML 1.0 and DOM Level 2 HTML.
HTML5 aims to reduce the use of proprietary plug-in based rich internet application (RIA) technologies such as Adobe Flash, Microsoft Silverlight, and Sun JavaFX, though it would take many years to do so.

Combining the data above...
If the average video is 3.7 minutes long and the only call to action was at the end of the video, 83.38% of the viewers would have dropped off before viewing the call to action.
Place calls to action throughout the video and keep the video at around 60 seconds or less to optimize the effectiveness of your online video.
