Commentate that - open to bidding

a app like Instagram but you post a video without sound and then your followers post all different commendations instead of a comment and you click on the commendations to listen and watch! you take a video of any length, that video automatically saves, then once you think of a hilarious commentary you simply commentate that video. once you've mastered your commentary you post it to the app and your humor gets shared to everyone. its great because if you mess up you can just go back until you get it right. i'm sure you've seen the "greg jennings" video and the "deer commentary" on youtube! so why not create a whole database
