Configure encoding
l
the type of motion that is captured; and
l
number of users accessing the stream.
When adjusting the frame rate, you may need to try different values to
achieve the best outcome. The following table provides the performance
expectations when typical settings are used.
Bitrate
In general, higher bitrate mean higher image quality in the stream, at the
cost of higher bandwidth needed to transmit it.
For comparison against something you are likely familiar with, an HD Blu-
ray video is typically in the range of 20 mbps, standard-definition DVD is
usually 6 mbps.
If you don't know what value to use, a good place to start is 5000 kbps
(slightly less than a typical DVD). Test to see how this works for your
viewers and adjust.
Configure audio codec
If your channel sources included audio (see
or Create a multi-source channel), your
stream will be default use the AAC audio codec at 48 kHz. You can modify this setting to best match your
