There's really not much new in the clip, tbh. It's mostly just some extended scenes of the panda village and Po meeting a few more random villagers. I think if you've seen the previous trailer, it shouldn't spoil much, if anything, for you.
It's not so much plot spoilers I'm trying to avoid, though. Trailer are purposely tailored to be somewhat "misleading" by not giving the context of what you see, whereas clips are straight from the film and therefore filled with more context. I want to save the actual, sequential footage of the film for when it comes out, even if it doesn't really reveal anything new.
