I'm bringing this topic back to life, if only to see what other people might be using for their startup videos. For me, I found two vids online which exemplify the gaming culture somewhat, and I've always loved both of them. That being said, they might not be 'acceptable' startup material, but I think they're impressive nonetheless. I'm sure many of you have likely seen one (or both) of them at some time or another.
I like them for random startups, and since you might be talking to buddies or otherwise busy while starting up, they might be just the thing to add more 'wow'... ...especially since I don't have any experience editing together my own videos.
