.NETcoder to create app for YouTube Video of Image Slideshow

Need to create slideshows of images (pan and zoom) with ability to post compiled videos to YouTube. And then the YouTube videos would be embededed on a website. This must be achieved dynamically. This module will be incorporated into my current website application which is a .NET C# application. The images are by http url. I'm not quite familiar with how YouTube works. I need to be able to have a slideshow of images using some type of flash player (just guessing) and then compile it as a movie to upload to YouTube. Or feed a string of image urls to YouTube to make a movie. The video also needs to have the ability to have voice over with maybe some background music. The voice over will need to be dynamic to read captions for the images. I have examples of other videos. To be clear, this project needs to make use of sending videos dynamically to YouTube (probably using an API) and then in return get the embed code in order to display on the website. Also, this project needs to be able to run on a Windows 64 bit server. If server-side code required then it needs to be c#.net. Server-side code needs to be done in C#.net 2.0. Database needs to be SQL Server 2005 or 2008.
