Parameter
Function
Encode mode
There are seven options: H.264, H.264H, H.264B, H.265,
MJPEG and MPEG4.
H.264: Main Profile encode mode.
H.264H: High Profile encode mode.
H.264B: Baseline Profile encode mode.
H.265: Main Profile encode mode.
MJPEG: In this encode mode, the video needs to enlarge
bit stream to guarantee the video definition. You can use
the max bit stream value in the recommended bit to get the
better video output effect.
Smart Codec
It can set smart codes as on or off.
Resolution
There are multiple resolution types. You can select from the
dropdown list.
For each resolution, the recommended bit stream value is
different.
Frame Rate (FPS)
PAL: 1～25f/s，NTSC: 1～50f/s..
The frame rate may vary due to different resolutions.
Bit Rate Type
There are two options: VBR and CBR.
Please note, you can set video quality in VBR mode.
In MJPEG encode mode, only CBR is available.
Reference Bit Rate
Recommend a reasonable bit rate value range according to the
resolution and frame rate you have set.
Bit Rate
In VBR, the bit rate here is the max value.
In CBR, the value is fixed.
Refer to “Reference Bit Rate”, bit rate value can provide
best reference range.
I Frame interval
Here you can set the P frame amount between two I frames, the
range varies according to the frame rate, the max is 150, it is
recommended to set twice as big as the frame rate.
SVC
Frame rate can realize layered coding, it is a scalable encoding
mode in time domain, and it is 1 by default, which is not layered.
It can set 2, 3, 4 layer coding setting.
Watermark Settings
By calibrating watermark, to see if video is modified. Select
Watermark function. Default watermark is Digital CCTV.
Watermark character can only be number, letter, _, - within 128
characters.
