Post types in Obox Themes have a custom theme options panel where you can setup special features such as featured videos. We strongly recommend using the Video Link field to take advantage of oEmbed, which is a set of advanced functions used by several popular providers such as YouTube, Vimeo and DailyMotion (and Twitter and Flickr too!). See How To Add a Featured Video for details on using this feature.
oEmbed links enable your posts to display extras such as likes and views, and will also auto-generate featured thumbnails for your videos. This is explained more under your theme’s documentation.
