Parameter
Description
Encoding
protocol
Set the coding protocol based on the site requirements.
The options are as follows:
– H.264: The H.264 protocol requires relatively small
bandwidth to ensure video quality.
– MJPEG: The MJPEG protocol decodes and displays
each frame independently without referring to the
previous and next frames. This protocol has a small
compression ratio and requires large bandwidth to
ensure video quality. This protocol is suitable for
video editing.
– H.265: The H.265 protocol is bandwidth-conserving
compared with the H.264 protocol.
Encoding
complexity
The options of H.264 profiles include Base profile, Main
profile, and High profile. Among these profiles, the
baseline profile has the lowest encoding compression
performance and lowest requirements on hardware
decoding performance, while the high profile has the
highest.
Resolution
A higher resolution indicates clearer images and higher
bandwidth consumption.
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 configured
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.
