Video/Audio.
In this interface, you can set the resolution, frame rate, bitrate type and video quality.
Three video streams can be adjustable.
Resolution : The higher the resolution is, the bigger the image is.
Frame rate : The higher the frame rate is, the more fluent the video will. However, more storage
room and bandwidth will be required.
Bitrate type : Including CBR and VBR. CBR means that the video compression bitrate will
always be kept constant. This will not only facilitate better image quality but will also help to
calculate the capacity of the recording. VBR means that the compression bitrate can be
adjustable according to the change of the video resources. This will help to optimize the network
bandwidth.
Video Quality : If VBR is selected, you will need to choose image quality. The higher the image
quality you choose, the more bitrate will be required.
Bitrate : Please choose it according to the actual network situation. The higher the bitrate –
the better is the image quality (less compression)
I Frame interval : It is recommended to use the default value.
Video encoding profile : Baseline and main profile are available. Baseline profile is mainly
used in interactive application with low complexity and delay. Main profile is mainly used for
higher coding requirement.
Stream of snapping photos : Please set according to the requirement.
Video encode slice split : If enabled, you may get more fluency image even though using the
low-performance PC, but this may result in poorer image quality
Watermark : If selected, you can input the watermark theme. You may check the watermark
when playing back the local record in the search interface, lest the record files is tampered.
