Multi-Stream: It means the same video source is encoded in several streams with
different resolutions. This parameter can be configured according to actual request
and the setting will be validated after reboot.
Stream Type: Configure the resolution and bitrate of main or secondary stream.
Resolution: According to the requirements of image quality by user, select resolution
from the dropdown list.
Bit Rate Type: Options include CBR and VBR.
Image Quality: When selecting "VBR", select image quality level from the dropdown
list according to actual requirements.
Frame Rate: Set the encoding frames per second.
Average Bit Rate: Set the average bit rate for CBR.
Encoding Format: Select according to actual requirements, options including H.264,
H.265 and MJPEG.
Encoding Complexity: Select encoding complexity level according to actual request.
Under the same bitrate, the higher the complexity level is, the better quality the
image will have and the more bandwidth it will require. When the encoding format is
MJPEG, the encoding complexity is certain to be low while when the encoding
format is H.265, the encoding complexity is certain to be middle.
Max Key Frame Interval: Configure the interval frames between two key frames,
ranging 1 ~ 250. Suggest applying the default value 75.
Smart Encoding: Enabling "Smart Encoding" will reduce the frame rate. When
enabling Smart Encoding under low bit rate, the image quality will be improved.
Please select according to actual request. It takes effect after reboot.
Stream Smoothing Factor: Drag the slide bar or enter a number to set the value. The
smaller the value is, the clearer the image will be; the larger the value is, the
smoother the stream transmission will be.
Note:
 When the bit rate type is "VBR", the parameter "Average Bit Rate" will turn to "Bit
Rate Upper Limit", whose range is 32 ~ 16384 (Kbps) and the default being
4096.
 The parameter of Image Quality is enabled only when "VBR" is selected and it
will remain "Middle" when "CBR" is selected.

Different encoding formats have different levels of encoding complexity.

The higher the Encoding Complexity is, the more the stream will be compressed.
In this way it will relieve bandwidth restriction somehow, but meanwhile it will
also occupy the CPU resource of more devices. Suggest using the default level.

After enabling Smart Encoding, some functions will be disabled, such as ROI
and Max Key Frame Interval.
