The accepted answer is detailed and feels really close to what you are asking for.

edit: I found an example here: http://www.aforgenet.com/framework/docs/html/4ee1742c-44d3-b250-d6aa-90cd2d606611.htm

int width  = 320;
int height = 240;

// create instance of video writer
var writer = new VideoFileWriter( );
// create new video file
writer.Open( "test.avi", width, height, 25, VideoCodec.MPEG4 );
// create a bitmap to save into the video file
var image = new Bitmap( width, height, PixelFormat.Format24bppRgb );
// write 1000 video frames
for ( int i = 0; i < 1000; i++ )
{
    image.SetPixel( i % width, i % height, Color.Red );
    writer.WriteVideoFrame( image );
}
writer.Close( );
