Breast cancer awareness

My classes focused on breast cancer awareness month the past two weeks. They had to create a public service announcement (psa) about breast cancer for one project and create ribbons and psa signs for the school. The student played a lot (of course) and completed the ribbons and signs for the school. The hallway in front of my class looks amazing. I was like a proud mommy for the work that the students completed. However, some of the psa were not that good. They had the content, but little creative thought when into them. So, when we began to video tape themselves, the students began to realized they needed or wanted music and some type of background. I believe that the students are not use to doing this type of work in class and don't believe me when I say we will record it. I tell them that I want their work to be good enough to be on TV or radio and they look surprised of my expectations. I think they are coming around in believing me, but the assignment is due now. So, my heart says let them do it over but the time clock says that we need to move on to the next topic. How do I improve the quality of the project? How do I grade the students work? (yes, I gave a rubric, but if I use it to grade their project the grades will not be that great)
