Encode
 Enable Preview
1. Select ON to enable to Display Video on the monitor that is connected to the
Composite or HD-SDI Video Port.
2. Select the Output Format according to the end of the Video Page.
When Enable Preview is ON, Dual Streaming is not available. When the video is
transmitted directly to the monitor through BNC cable, the video does not go
thorough network and encoding. Therefore, there is less delay and no effect
from network limitation.
 Input Format
Choose Video Type to be used between Composite NTSC or Composite.
 Input De-Interlace
De-Interlace Function is activated if ON is selected.
 Resolution
Select Video Encoding Resolution. Scaling Option is used when Encoding Resolution
is different from Input Resolution. Without Scaling 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.
 Frame Rate
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 Video Quality or Bit Rate: Video Quality (VBR) or
Bit Rate (CBR). If Bit Rate is selected, the Video Encoding will be affected by the Bit
Rate Value entered. Therefore, Bit Rate Mode corresponds to CBR (Constant Bit Rate)
Encoding. If Video Quality is selected, the Video Encoding will be affected by the
quality of image selected. Therefore, Quality Mode corresponds to VBR (Variable Bit
Rate) Encoding.
 Quality
Select Video Quality. 7 levels are available. Quality Mode (VBR Encoding) encodes
every frame in a constant quality. Therefore, resulting Bit Rate may vary depending on
the complexity or activity changes in the Input Video. Quality Mode is preferred when
Constant Video Quality is required and Network Bandwidth is sufficient for streaming of
a highly varying Bit Rate.
