I have used Unity to develop multiple games and I think I can surely fix your animation. I am not so sure about the video, however, because I do not know if it is technically possible. Unity itself only supports full-screen video for mobile apps but maybe your plugin has solved this. If you think my proposal is good, please contact me. I think I can even do the project for less, but the minimum bid is 20 US dollars.
If you think I can help you finish your app, which I would love to do, please contact me.
