I could not manage to get the above example to work. However I did find another library that works amazingly well once. Try via NuGet "accord.extensions.imaging.io", then I wrote the following little function:

    private void makeAvi(string imageInputfolderName, string outVideoFileName, float fps = 12.0f, string imgSearchPattern = "*.png")
    {   // reads all images in folder 
        VideoWriter w = new VideoWriter(outVideoFileName, 
            new Accord.Extensions.Size(480, 640), fps, true);
        Accord.Extensions.Imaging.ImageDirectoryReader ir = 
            new ImageDirectoryReader(imageInputfolderName, imgSearchPattern);
        while (ir.Position < ir.Length)
        {
            IImage i = ir.Read();
            w.Write(i);
        }
        w.Close();
    }

It reads all images from a folder and makes a video out of them.

If you want to make it nicer you could probably read the image dimensions instead of hard coding, but you got the point.

I bit late but I have made a tutorial on how I solved my similar problem if you did not succeed yet: Image sequence to video stream?

Same question asked here.

The answer there points to here, which is not exactly what you're doing, but is easily configurable to do the job.
