You should store current state in some variable (e.g. _capturing). When variable changing, you refresh IsEnabled property.

Xaml code:

C# code:

public partial class MainWindow : Window
{
    private bool _capturing;

    public MainWindow()
    {
        InitializeComponent();

        // Some code

        _capturing = false;
        UpdateButtons();
    }

    private void StartButton_Click(object sender, RoutedEventArgs e)
    {
        // Some code

        _capturing = true;
        UpdateButtons();
    }

    private void CaptureButton_Click(object sender, RoutedEventArgs e)
    {
        // Some code

        UpdateButtons();
    }

    private void UpdateButtons()
    {
        StartButton.IsEnabled = !_capturing;
        CaptureButton.IsEnabled = _capturing;
    }
}

UPDATE

You should add click handler and your xaml code will work:
