Yesterday, The CW released a minute-long promo trailer for the fourth season of The Vampire Diaries - you can find it here - and now, thanks to Mr. Video, we have some screen captures from a "generic" 30-second version of the trailer.
It's mostly like the long one, though almost all clips are from Season 4. The recap clips from the Season 3 finale don't seem to be present. To our knowledge, there are no clips that aren't already in the longer promo, though more eagle-eyed vampire fans than ourselves might see something that hasn't been seen before.
Enjoy the screencaps, and feel free to come by KSiteTV's TVD forum! The Vampire Diaries Season 4 premieres October 11, 2012 on The CW.
