There were recently two new clan introduction videos released for Bloodlines 2: Brujah and Tremere.
If you're even the least bit familiar with VtM you'll know that clan Brujah are your general anarchist/rebellion type vampires. They're pretty set in the "I'll do what I want, when I want, and how I want." mindset and heaven help you if you get in their way.
Clan Tremere are, more-or-less, are the mages of the Vampire world, even nicknamed Warlocks. They are very interested in the mystical arts as well as being a fairly "young" clan. Clan Tremere are heavily mistrusted by most of the other clans not simply because of their sorceries but because the actual origin of the clan is not "natural". Tremere himself first becoming a vampire through ancient rituals, then diablerizing the 3rd generation Antediluvian, Saulot to cement the Tremere's place among the clans.
Check out the introduction videos below for the Brujah and Tremere clans.
