 Quality
Select the required Video quality. Eight levels of quality are available.
Quality mode (VBR encoding) adjusts the bit rate according to the image complexity, using higher
bandwidth for increased activity in the video and lower bandwidth for decreased activity.
For active video content such as sports, or when network bandwidth is limited, It is reccomended
that CBR or Bit Rate encoding be used.
 Bit rate
Set the bit rate value between 32 ~ 8000kbps.
Bit rate mode (CBR encoding) allows you to set a fixed bit rate that consumes a predictable
amount of bandwidth. If the network capacity is sufficient use of a fixed bit rate of 4096 kbps
or higher will maintain a high quality picture regardless of content.
 I-Frame Interval
Set the I-frame Interval between 0 and 255.
There will be no I-frames if 0 is selected.
 H.264 Profile
Select the H.264 Profile: High Profile or Baseline Profile
The standard defines various sets of capabilities which are referred to as profiles targeting specific
classes of applications.
- High Profile (HiP)
The primary profile for broadcast and disc storage applications particularly for high-definition
television applications (for example, this is the profile adopted by the Blu-ray Disc storage format and
the DVB HDTV broadcast service).
- Baseline Profile (BP)
Primarily for low-cost applications that require additional data loss robustness, this profile is used in
some videoconferencing and mobile applications. This profile includes all features that are supported
in the Constrained Baseline Profile, plus three additional features that can be used for loss
robustness (or for other purposes such as low-delay multi-point video stream compositing).
