Profile
Profile
sets the H.264 encoding profile for your stream. The
available options are Baseline , Main , and High . Typically,
High profile provides the best image quality and is suitable
in most instances. However, depending on the decoder
used when viewing the stream, such as with mobiles
devices, a Main or Baseline profile may be required.
Video Bitrate (bps)
The bitrate of the video specifies the amount of
information stored in the video. The higher the bitrate is,
the clearer the video is. However, when choosing your
encoding settings for streaming, you should first check
your available upload bandwidth. A good rule of thumb is
for the bitrate of your stream to use no more than 50% of
your available upload bandwidth capacity on a
DEDICATED
line. For example, if the result you get from a speed test
shows that you have 2Mbps of upload speed available,
your combined audio and video bitrate should not exceed
1Mbps.
Usually high bitrate means good image quality; however,
there are also exceptions. For example, SD video may
appear acceptable at 1000 Kbps (1M) but HD video is
unacceptable at 1000 Kbps. Therefore we recommend the
following settings for your video bitrate:

When NVS-31 is in record-only mode, the
recommended video bitrate is 16 Mbps.

When NVS-31 is in stream-only mode, the
recommended video bitrate is 10 Mbps.

When NVS-31 streams and records simultaneously,
sum of the stream and record video bitrates should
not exceed 12Mbps.
Audio Bitrate (bps)
The NVS-31 offers the user the following audio bitrates at
which you may want to stream the audio. It is
recommended to select 128Kbps or higher.
