    WM Templates Seven selectable templates have been preconfigured for many common applications. Templates apply to Video encoder settings. In general, finer resolution detail and smoother motion will require more resources and more network bandwidth. The optimum is to display the finest detail and smoothest motion possible given the network resources available.
