Set the following parameters for the selected main stream or sub-stream.
Video Type:
Select the stream type to video stream, or video & audio composite
stream. The audio signal will be recorded only when the Video Type is Video &
Audio.
Resolution:
For the main stream, the resolution of the video output is 1280 x 720P,
and for the sub stream, the resolution of the video output is 640 x 480.
Bitrate Type:
Select the bitrate type to constant or variable.
Video Quality:
If you set the bitrate type as constant, the video quality is medium.
If you set the bitrate type as variable, multiple choices of the video quality can be
selected: Lowest, Lower, Low, Medium, Higher, and Highest.
Frame Rate:
Set the frame rate. The frame rate describes the frequency at which
the video stream is updated and it is measured by frames per second (fps). A
higher frame rate is advantageous when there is movement in the video stream,
as it maintains image quality throughout.
Max. Bitrate:
Set the max. bitrate. For the main stream, the max. bitrate ranges
from 32 to 4096 Kbps, and for the sub stream, the max. bitrate ranges from 32 to
2048 Kbps. The higher value corresponds to the higher video quality, but the
better bandwidth is required.
Video Encoding:
If the stream type is set to main stream, H.264 is selectable, and
if the stream type is set to sub stream, H.264 is selectable.
