-
GOP (Group of Pictures) size:
Set up the number of P frames between each I frame
-
Profile:
The profile defines the subset of bit stream features in H.264, H.265 (HEVC) stream,
including colour reproduction and additional video compression. Select main for an
intermediate profile with a medium compression ratio. Select High for a complex profile
with a high compression ratio.
-
Bitrate mode:
Select the bit rate control scheme of video compression from CBR (Constant
Bit Rate) or VBR (Variable Bit Rate).
o
CBR: Guarantees the designated constant bit rate; video quality will vary with scene
complexity.
o
VBR: Guarantees the designated quality; the bit rate of video stream is changed in
this mode depending on scene complexity.
-
Target Bitrate:
If Bitrate mode is set to be CBR, user can set the Target Bitrate
-
Quality:
For VBR control mode, the Target Quality of video can be set up
-
Smart Bitrate Control:
Off / CVBR (Framerate priority) / CVBR (Quality priority) / CBR
-
Extension option:
SVC-T (Scalable Video Coding) can be selected. It is a video compression
algorithm that enables effective and efficient transmission of video files over low bandwidth
networks
To make any changes to this setting effectiv
e, press “apply” button at the bottom of the menu (see
