Encode

Enable Preview
1. Select ON to display video on the monitor that is connected to the composite or HD-SDI
video port.
2. Select the Output format accordingly in the end of the Video page.
Note that 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
signal bypasses the network and encoding.

Resolution
Select the video encoding resolution required.
18 resolutions are available.
The Scaling option is used when the encoding resolution is different from the input compression. Without
the Scaling option, input video will be croped according to the encoding resolution. On the other hand,
if Scaling is selected, the input video will be adjusted according to the encoding resolution.

Frame rate
Select the maximum number of frames per second for the video stream.
A frame rate of 1,2,3,4,5,6,8,10,15,20,25 and 30 can be selected. The actual frame rate of video can be less
than the maximum frame rate set due to any network bandwidth limitation.

Preference
Select the encoding mode to control video quality: Quality or Bit rate.
If „Bit rat
e‟
is selected, the video encoding will be affected by the „Bit rate
‟
value entered. Therefore, 'Bit
rate' mode is CBR (Constant Bit rate) encoding.
If „Quality
‟
is selected, the video encoding will be affected by the quality of image selected. Therefore,
'Quality' mode is VBR (Variable Bit Rate) encoding.
