ChristopherPike recently released his 2007 Save Enterprise promotional videos intended to garner attention for the campaign and show Enterprise's potential.
The first is a general promotional video for a Direct-to-DVD release. It shows us where Enterprise has been and where it could go in a fifth season. It uses scenes from the Star Trek: Enterprise, the 2006 Direct-to-DVD trailer, and Star Trek: Nemesis to paint of a vivid picture of the potential in Enterprise.
The second is a hypothetical revamped opening credits for season five, using footage cut from several different episodes of Enterprise, as well as the extended theme from the closing credits and the famous "Space... the final frontier" voice over as done by Scott Bakula.
