Save Video with shader effects from webcam

Hello,

I am working on a application which is having features to save Images and videos  from webcam  with  shader effects. I am using WPFMediakit for the same. I have done Saving Images with effects, It is working fine even I have added video saving feature with the help of http://learnwpf.com/post/2010/01/08/Adding-Simeltaneous-Video-Recording-2b-Playback-to-WPFMediaKits-VideoCaptureElement.aspx.

Now When I am adding shader Effects on Videocapturelement, It is not saving on video, Video is plain with  no effects. Please help me.

Thanks
