The first video features Michael Sheen's Volturi leader Aro, as Irina (Maggie Grace) informs him about Edward and Bella Cullen's offspring Renesmee.
Kristen Stewart's Bella narrates the second preview clip, which shows sinister Volturi Jane (Dakota Fanning) and her brother Alec (Cameron Bright) using their powers to rob victims of "sight, sound and touch".
The pair of clips arrive on the back of last week's arm-wrestling showdown between Bella and Emmet Cullen (Kellan Lutz).
Breaking Dawn - Part 2 will be the shortest Twilight movie yet, clocking in at 115 minutes. The longest film in the vampire franchise is 2009's New Moon, which has a running time of 130 minutes.
