Resolution
Select video compression resolution. Compression resolutions are different depending on input
formats.
The scaling
option is used when compression resolution is different from input
compression. Without
the scaling
option, the input video image will be cut according to
compression resolution. On the other hand, if
scaling
is selected, the input video size will be
adjusted to the compression resolution.
"
Frame rate
Determine the maximum number of frames per second for the video images to be compressed.
The frame rate of actually transmitted video can be affected by a network bandwidth limitation
"
Preference
Preference for video compression and transmission: With ‘Bit rate’ selected, the video
compression will be affected by the ‘Bit rate’ value entered. With ‘Quality’ selected, the video
compression will be effected by the quality of image selected. Therefore, ‘Bit rate’ and ‘Quality’
corresponds to CBR (Constant Bit rate) and VBR (Variable Bit rate) respectively. CBR will try
and maintain an average bit rate equal to the Bitrate value set. In Quality mode the bit rate will
vary within limits determined by the Quality setting selected.
"
Quality
Select Video quality. 8 levels of quality are available.
Quality mode (VBR encoding) adjusts the bit rate according to the image complexity, using
higher bandwidth for increased activity in the video and lower bandwidth for decreased activity.
It is preferred when the activity changes in the video are significant or the network capacity is
insufficient to maintain certain bit rates continually.
"
Bit rate
Determine bit rate value between 32 ~ 8000kbps.
Bit rate mode (CBR encoding) allows you to set a fixed target bit rate that consumes a
predictable amount of bandwidth.
