The clip shows Bella Swan (Kristen Stewart) and Edward Cullen (Robert Pattinson) starting off their honeymoon in a luxurious setting after their wedding.
In the video, Edward lifts Bella over the threshold because he is "nothing if not traditional", before she asks him for a "few human minutes" as they set out in their married life.
The Twilight Saga: Breaking Dawn - Part 1 is released in cinemas worldwide on November 18, followed by Breaking Dawn - Part 2 on November 16, 2012.
It will be preceded by special screenings of the first three films in the series in selected cinemas.
Two new TV spots were released for the first part of the series finale earlier this month.
