Figure 8. Configuration: Encoder > Video – Part 2
Video Template Settings -- Slot1 (Video Rate1)
The video settings can be changed on this page or by modifying a template setting on the
Configuration: Encoder > Template page of IWS. Any changes you make on this page
override the template; they do not change it. If you are using only one video rate you can
choose any resolution from the complete list of supported resolutions (with minor
exceptions). However when you enable
Video Rate2 or Video Rate3 the selections are
restricted. Tables 9 and 10 below show the resolution combinations that are allowed. For
example, 640x480 can be configured on one video encoder and 320x240 can be configured
on another video encoder, but 320x240 and 240x180 are not allowed together. Once
Video Rate2 and/or Video Rate3 are enabled they will be available for selection on the
Multicast, Server, and Archiver pages. If they have been selected for inclusion on the those
pages an error will appear on this page if you attempt to disable them. The resolutions
available for NTSC and PAL are basically identical. The only difference is in 16:9 mode
(Table 10) where NTSC has 384x216 and PAL has 512x288.
