Vassar “Your Space”?

So I just submitted my application last night ED to Vassar and included a “Your Space” submission as well. It’s a YouTube video, something really simple from my talent show last year because I figured why not- it shows I’m willing to try new things. What I’m worried about is that it makes me look too nervous or something like that (especially the intro I made). So I guess my question is how important is the “Your Space” submission to the admission officers? Like will it possibly hurt my chances of getting in?
