Found this clip last night and was really amazed at how much detail this guy pulled from his dvx camera. He won the zombie dvxfest contest they did a little while back. If you don't like zombies or a little blood don't look (not too much blood). The detail is very nice....the outside shots are great (he used 1/150 shutter outside). Not really Vegas related but it is nice to see what results can be achieved with a regular three chipper (and some good color work in post). He used FCP and After Effects but I see no reason this couldn't be done in Vegas.

Edit: in addition to blood and zombies there is a tiny bit of language (full disclosure here)
