Video Quality:
When bitrate type is selected as
Variable
, 6 levels of video quality are selectable.
Frame Rate:
The frame rate is to describe the frequency at which the video stream is updated and it is
measured by frames per second (fps). A higher frame rate is advantageous when there is
movement in the video stream, as it maintains image quality throughout.
Max. Bitrate:
Set the max. bitrate to 256~16384Kbps. The higher value corresponds to the higher video
quality, but the higher bandwidth is required.
Video Encoding:
The
Video Encoding
standard can be set to H.264.
H.264+:
Set it as ON or OFF.
Profile:
Basic Profile, Main Profile and High Profile are selectable.
I Frame Interval:
Set the I-Frame interval from 1 to 400.
SVC:
Scalable Video Coding is an extension of the H.264/AVC standard. Select OFF/ON to
disable/enable the SVC function. Select Auto, and the device will automatically extract frames
from the original video when the network bandwidth is insufficient.
Smoothing:
It refers to the smoothness of the stream. The higher value of the smoothing, the better
fluency of the stream, though, the video quality may not be so satisfied. The lower value of
the smoothing, the higher quality of the stream, though it may appear not fluent.
