Parameter Description
Bit rate type This parameter is available only when you set Encoding
protocol to H.264 or H.265.
The bit rate is measured by data bits transmitted in a
unit of time.
– Variable bit rate: The bit rate varies depending on
the image complexity to ensure the clarity of images
with great dynamic changes. The bit rate is low if the
image is simple or static. The variable bit rate is
recommended.
– Constant bit rate: The constant bit rate remains the
same. The upper limit of the instantaneous bit rate is
set to 110%. If the bit rate is incorrectly
congured
for images with great dynamic changes, the images
will be unclear.
Max. bit rate This parameter is available only when you set Bit rate
type to Variable bit rate.
The bit rate range depends on the selected resolution.
Bit rate value Average bit rate when Bit rate type is set to Constant
bit rate.
The bit rate range depends on the selected resolution.
Bit rate control
mode
This parameter is available only when you set Bit rate
type to Constant bit rate. The options are as follows:
– Frame rate priority: Ensure the smoothness of the
video image.
– Image quality priority: Ensure the quality of the
video image.
Frame rate The frame rate is measured by the number of frames
displayed in a second.
A higher frame rate indicates clearer and smoother
images and higher bandwidth consumption.
Image quality This parameter is available only when you set Encoding
protocol to H.264 or H.265 and Bit rate type to
Variable bit rate.
Better image quality requires higher bandwidth.
Therefore, select proper image quality based on the site
requirements.
I-frame interval This parameter is available only when you set Encoding
protocol to H.264 or H.265.
An I frame is an intra-coded frame that represents a
xed image independent of other picture types. Each
group of pictures (GOP) begins with this type of frame.
A smaller I-frame interval indicates better video quality
and higher bandwidth consumption.
