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 the video can be less than the maximum frame rate set due to the network
bandwidth limitation.
-
Preference
Select Encoding Mode to control the video quality or bitrate:
Quality (VBR)
or
Bit
Rate (CBR)
. If Bitrate is selected, the video encoding will be prompted by the Bitrate
value entered. Therefore, the Bitrate mode corresponds to CBR (Constant Bit Rate)
encoding. If Quality is selected, the video encoding will be prompted by the quality of
image selected. Therefore, Quality mode corresponds to VBR (Variable Bit Rate)
encoding.
-
Quality
Select Quality Level: 7 Levels of Quality are available.
Quality Mode (VBR
Encoding)
encodes every frame in a constant quality. Therefore, resulting bitrate
may vary a lot depending on the complexity or activity changes in the input video.
Quality Mode is preferred when constant video quality is required and the network
bandwidth is enough for delivering the stream of highly varying bitrate.
-
Bitrate
Bitrate value ranges between 32 and 16Mbps.
Bitrate Mode (CBR Encoding)
allows you to set a fixed target bitrate that consumes a predictable amount of
bandwidth. In order to stay within the bitrate limit, video quality is controlled
dynamically according to the complexity or activity changes in the input video.
-
I-Frame Interval
I-Frame Interval ranges between 1 and 255.

H.264 Profile
Select the H.264 Profile:
High Profile
or
Baseline Profile
A profile defines the various capabilities which target specific applications.
1.
High Profile
High Profile is the primary profile for broadcast and disc storage applications;
particularly for high-definition television application.
2.
Baseline Profile
Baseline Profile is for low-cost applications that require additional data loss
robustness used in some videoconferencing and mobile application. This
profile includes all the features that are supported in the constrained baseline
profile, plus three additional features that can be used for loss robustness.
