<h4>1、Introduction</h4>
<p>The table details the full frame quality bitrate comparison table and the video package length calculation formula for different platforms.</p>
<h4>2、Calculation formula</h4>
<p><strong>PAL:</strong> recording packing time (s) = disk block size / [(frame rate / 25) X code rate X number of channels]</p>
<p><strong>NTSC: </strong>video packing time(s) = disk data block size / [(frame rate / 30) X code rate X number of channels]</p>
<p><strong>Examples:</strong>
Lian Yong98323，The resolution of the main stream is set to 1080P, the picture quality is set to 1, the standard is PAL, and the resulting bit rate is 8192kbps, the machine has a total of 6 channels of video recording, the frame rate is set to 15, and the device disk size is 1T, (follow the table instructions，data block size of 1G，1GB=1073741824 byte)，The length of the video package is calculated according to the formula ：1073741824 / [（15/25）X （8192 X 1024 / 8） X 6 ] = 284（s）</p>
