Bitrate Type

CBR: Constant Bit Rate (CBR) is used to
maintain a specific bit rate by varying the
quality of video streams. CBR is preferred
when limited bandwidth is available. The
disadvantage is that video quality will vary and
may decrease significantly with increased
motion in the scene.

VBR: When using Variable Bit Rate (VBR),
video quality is kept as constant as possible,
at the cost of a varying bit rate, and regardless
of whether there is motion in the image. VBR
is ideal when high quality is a requirement,
especially when there is motion in the picture.
Bit Rate(Kbps)
Number of bits transferred per second. Select a
value or select
Custom and then set a value as
needed.
Frame Rate(fps) Number of frames per second.
Image Quality
This parameter is effective only when Bitrate
Type is set to VBR . 9 levels are provided.
I Frame Interval
Number of frames between two adjacent I
frames.
I Frame Range Range of I frames.
Smoothing
Use the slider to control the sudden increase of
bit rate.
Smart Encoding
The advanced mode achieves higher
compression ratios.
