To add a video profile
You can add as many codec as necessary so that a variety of profiles can be applied
according to the recording condition.
Select a profile number.
Provide the name and select a codec.
Specify the conditions under which the codec will be applied.
Specify the details of the selected codec including resolution and frame rate.
Resolution : Set the video size of the MPEG4, H.264, and MJPEG files.
Framerate : Specify the frame rate.
Compression : Specify the compression rate of the video.
Bitrate control : You can select either the fixed bit rate or the variable one for the
compression type.
If you set the resolution to 1280X1024, the maximum frame rate is 22 fps.
Target bitrate : Specify the bit rate at which you will transfer the video.
Encoding priority : You can set the video transfer method to Framerate or
Compression.
GOP size : Select a GOP size between 1 and 15.
Profile : The H.264 profiling method is fixed to <HIGH>.
Entropy coding : Reduce the possible compression loss due to encoding.
Multicast (VNP) : Specify the use of the VNP protocol.
IPv4 : Enter an IPv4 address with which you can connect to the IPv4 network.
Port : Specify the video communication port.
TTL : Set the TTL for the VNP packet.
Multicast (RTP) : Specify the use of the RTP protocol.
IPv4 : Enter an IPv4 address with which you can connect to the IPv4 network.
Port : Specify the video communication port.
TTL : You can set the TTL for the RTP packet.
What is GOP size?
GOP (Group of Pictures) is a set of video frames for MPEG4 and H.264 format
compression, indicating a collection of frames from the initial I-Frame (key frame) to the
next I-Frame. GOP consists of 2 kinds of frames: I-Frame and P-Frame.
I-Frame is the basic frame for the compression, also known as Key Frame, which
contains one complete image data. P-Frame contains only the data that has changed
from the preceding I-Frame.
You can set between 1 and 15 for the MPEG4 and H.264 CODEC.
