The 21st Century Communication and Video Accessibility Act, recently signed into US law on October 8, 2010, requires that producers and content creators of online video must provide closed captioning.

For videos posted to YouTube and other video sharing sites, content creators should consider adding a full written transcript of the video as a way to increase audience engagement and interaction.

Before filming content for web video marketing purposes, content creators need to determine the reasons for creating audiovisual content.
