Operation Manual
Parameter
Description
This parameter can be configured only when the Bit Rate Type is set
as ABR.
The default value of the average bit rate is half of the max bit rate,
and the max bit rate keeps higher than the average bit rate.
Average Bit Rate
Supports for custom average bit rate.
The average bit rate should be greater than the max bit rate.
The number of P frames between two I frames, and the I Frame
Interval range changes as FPS changes.
It is recommended to set I Frame Interval twice as big as FPS.
I Frame Interval
When Encoding Strategy is AI Coding, the I Frame Interval under
CBR supports 1 second and 2 seconds for selection, and the I Frame
Interval under VBR or ABR supports 1 second and even values
between 1 second and 30 seconds for selection.
This parameter can be configured only when the Bit Rate Type is set
as VBR or ABR.
Virtual I Frame is inserted starting from an I frame interval of 4
seconds or more.
Virtual I Frame
You can enable or disable Virtual I Frame only when I Frame
Interval is greater than or equal to 4 seconds. It is enabled by default
and can be manually disabled.
SVC
Scaled video coding, is able to encode a high quality video bit stream
that contains one or more subset bit streams. When sending stream,
to improve fluency, the system will quit some data of related lays
according to the network status.
●1: The default value, which means that there is no layered coding.
●2, 3 and 4: The lay number that the video stream is packed.
Watermark
You can verify the watermark to check if the video has been
tampered.
