Picture 6-17 Encoding Format
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. The higher the resolution is, the more bandwidth it requires.
Bit Rate Type: Options include CBR and VBR, by which you can control stream rate.
CBR is fixed bit rate while VBR means the bit rate is adaptive within the upper limit.
CBR transfers stream by average bitrate with high speed compressing, but there
may be mosaic on the images; while VBR adjusts bitrate automatically with slow
compressing, but could ensure image sharpness under complex conditions.
Image Quality: When selecting “VBR”, select image quality level from the dropdown
list according to actual requirements. The higher the level is, the clearer the image
will look.
Frame Rate: Set the encoding frames per second. The higher the frame rate is, the
more bandwidth is required and the more storage it will take.
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.
