We have to remember that the audition is happening because they're going to be on this special, rather then it's own thing. And that it said right here when it first got announced that stuff would be voted on by the audience and that the MV will happen after the special is all finished with.

They will show all of the qualifiers' works live on the Big Chance show and the audience will vote for their favorite in real time. The winner will be revealed live. later, Morning Musume.'15 will work with the winning director to make and film the new music video for the next single.
Personally it's the fact that they will be on this special is happening that I'm more excited for rather than the idea of the audition itself. I assume they won't be the only audition on there and the special will have a lot of general public watching it who might not have been exposed to current MM yet. General public may become attached to some of the auditionees and end up paying attention to the upcoming single because they want to see the video and then hopefully the song will be kick-ass and we will hook more fans >D!
This also means we might get a few different styles of mini-MV type things with the 9-nin, that'll be cool.
