How to add Scroll news in a Video using C#?

I am new in this area. I am trying to create a n开发者_如何学Goews scroll bar which will scroll over a video using C# . Where will I find necessary helps, or is it even possible?

You can either overlay the video control with a transparent control or you can watermark the video with animated text. Have a look at Microsoft expression encoder, there's a free version. But since you want to scroll news, you'll want the text to be dynamic, so you'll probably need to do an overlay.
