To preview video captured in two panels

I am developing a program that is meant to get video from a capture device input and preview into two separate panels.

using DirectX.Capture;

So using the code below I am only able to view in one panel (panel1) and not both

public partial class myVideo : Form
{
    private Capture capture = null;
    private Filters filters = new Filters();

    public myVideo()
    {
        InitializeComponent();
    }

    private void btnPreview_Click(object sender, EventArgs e)
    {
        Filter videoDevice = null;

        capture = new Capture(filters.VideoInputDevices[0], null);
        capture.PreviewWindow = panel1;
        capture.PreviewWindow = panel2;
    }
}

Kindly help me figure out how to have it in two panels instead of one.
