6.3 Video Settings
1) Video Format
Support 50Hz (PAL) and 60Hz (NTSC) formats.
2) Encode Level
Support baseline, mainprofile and highprofile.
3) Encode Codec
Support H264 and MJPEG.
4) Resolution
First stream support 1920x1080, 1280x720.
Second stream support 1280x720; 640x360. The
bigger the resolution, the clearer the image, and
the larger the code stream, the more network
bandwidth will be taken.
5) Bit Rate
You can specify the bit rate, the larger the bit rate,
the clearer the image. The configuration of the
bit rate needs to be combined with the network
bandwidth. When the network bandwidth is
narrow and the bit rate is configured larger, the
video stream cannot be transmitted normally,
and the visual effect will be worse.
6) Frame Rate
You can specify the size of the frame rate, the
greater the frame rate, the smoother the image;
the smaller the frame, the more beating the
image.
7) I Key Frame Interval
Set the interval between two I frames, the bigger
the interval, the slower the response when
opening the image for the first time.
8) Bit Rate Control
Two modes for bit rate control:
CBR (Constant Bit Rate): Video coder will be
coding according to the preset speed.
VBR (Variable Bit Rate): Video coder will adjust
the speed based on preset speed to gain the best
image quality.
9) Slice Split Enable
Enable or disable the Slice Split function.
10) Split Mode
Split Mode Fixed bytes.
11) Slice Size
Size for slice.
