The video capture that Richard privided is from the scene in Hogsmeade where Harry has snuck into the village. When Harry is about to sneak into the pub, right before he goes in there, a man walks in wearing a kilt. He walks in kind of quick, so you have to keep your eyes peeled. You can also spot a man with a highland cow later in Hogsmeade.

Because the editors desaturated the colors so much (a wonderful effect for this film), it's hard to tell what tartan it is.
