to add a video profile
You can add as many codecs as necessary so that a variety of profiles can be applied
according to the recording condition.
1.
Select one from the <
video profile
> options.
2.
Provide the name and select a codec.
3.
Specify the conditions under which the codec will be applied.
4.
Specify the details of the selected codec including resolution and frame rate.
Click <

•
Resolution : Set the video size of the H.264 and MJPEG files.
•
Framerate : Specify the frame rate.
•
Compression : Specify the compression rate of the video.
•
Maximum bitrate : Specify the maximum bit rate of the video.
J
`
As the bit rate can be adjusted limitedly according to the resolution, frame rate and screen
complexity, the actual bit rate can be greater than the maximum bit rate. So you must
consider the use conditions when setting the value.
•
Target bitrate : Specify the bit rate at which you will transfer the video.
•
Bitrate control : You can select one from constant bit rate and variable bit rate for
compression. Constant bit rate (CBR) varies the video quality and fixes network
transfer bit rate, while variable bit rate emphasizes the quality by varying network
transfer bit rate.
J
`
If the bit-rate control is set to the Constant Bit Rate, the actual transmission frame rate
may be less than the set frame rate because the Frame Rate First Mode is changed to the
Compression Rate First Mode to ensure the highest image quality at a bit rate which is set
depending on the complexity of the screen.
•
Encoding priority : You can set the video transfer method to Framerate or
Compression.
•
GOV length : You can select the length of GOV.
(2Mega mode : 1~150, 3Mega mode : 1~100)
•
Profile : You can select the H.264 profiling method.
•
Entropy coding : Reduce the possible compression loss due to encoding.
•
Smart codec : Specify the use of Smart codec.
M
`
The Smart Codec will be active only if the codec is of H.264 and the compression system is
CBR.
