why not release the app and try to get that discovered and get feedback. Unless your video is viral material, its hard to get it discovered. You could try virool.com, youtube.com ads, collegehumor.com, facebook promotions. If you release your app in the app store, try freemyapps.com, submit to app review sites (search google), email to some campus list servers to get college students to use it. If worried about ratings, release it with different name than planned, get feedback, tune, and release it again with planned name / branding.
