Encode

Enable Preview
1. Select ON to enable the video display preview on the monitor.
2. Select the Output Format based on the video preview. Note: when Enable
Preview is ON , dual streaming is not available. When the video is transmitted
directly to the monitor through the BNC cable, the video is not sent through the
network. Therefore, video has less delay and no network limitations.

Resolution
Select video 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 and 30 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 the Video Quality or Bitrate : Quality (VBR) or Bit
Rate (CBR). If
‘Bitrate’ is selected, the video encoding will be effected 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 effected by the
quality of image selected. Therefore, the
“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.

Bit Rate
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
Determine I-Frame Interval 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.
