option, input video will be cut according to encoding resolution. On the other hand, if Scaling is
selected, input video will be adjusted according to encoding resolution.
-
Framerate
Determine the maximum number of frames per second for the video stream.
1,2,3,4,5,6,8,10,15,20,25,30 and 60 frame rate can be selected. The actual frame rate of video can
be less than the maximum frame rate set due to the network bandwidth limitation
-
Preference
Select encoding mode to control video quality or bitrate: Quality(VBR) or Bit rate(CBR). If ‘Bitrate’
sel
ected, the video encoding will be effected by the ‘Bitrate’ value entered. Therefore, “Bitrate” mode
corresponds to CBR (Constant Bit rate) encoding. If ‘Quality’ selected, the video encoding will be
effected by the quality of image selected. Therefore, “Quality” mode corresponds to VBR (Variable
Bit Rate) encoding.
-
Quality
Select Video quality. 7 levels of quality are available.
Quality mode (VBR encoding) tries to encode every frame in a constant quality. Therefore, resulting
bitrate may vary a lot depending on the complexity or activity changes in the input video. It is
preferred when constant video quality is required and network bandwidth is enough for delivering
the stream of highly varying bitrate.
-
Bitrate
Determine bitrate value between 32 ~ 16Mbps.
Bitrate mode (CBR encoding) allows you to set a fixed target bitrate that consumes a predictable
amount of bandwidth. In order to keep the bitrate limit, video quality is controlled dynamically
according to the complexity or activity changes in the input video.
-
I-Frame Interval
Determine I-frame Interval between 1 and 255.
-
H.264 Profile
Select 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 application.
