Configuration: Encoder
Configuration: Encoder > Template
Seven selectable templates have been preconfigured for many common applications. There
are always trade-offs when selecting 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 to both the WM Appliance sender and to the viewer who is receiving the WM
Appliance video streams. The Cable/DSL 128K High Motion template is the default template for
the WM Appliance. The appliance is configured and shipped with this template installed and
the values you initially see in IWS are those defined by this template. The templates are
briefly described in Table 8 below; they are described in detail in WM Templates
on
page 131.
Templates apply to
Video and Audio settings only. If, after applying a template, you override
any audio or video settings, the note Parameters do not match template will be displayed on
the Template page. A change on the template page also causes an interruption in the video
and audio output of all video and audio encoders and all transmissions including multicast,
HTTP, RTSPU, and Push. If an archive is in process, a template change causes the current
archive to be closed.

Note You cannot select and use a template when configuring multiple bit rate streams. In order
to select a template, Video Rate2, Video Rate3, and Audio Rate2, Audio Rate3 must be
disabled on the Configuration: Encoder > Video and Audio pages.
