There is a Calculation method of video file size. 

Video file size (MB) = recording time (s) * code rate (Kbps) / 8 / 1024

For example:  Resolution = 720P;  Quality = 3, Code Rate = 2048Kbps, Recording Time = 1 hour; channel =  1;

Then the Video File Size =  3600s * 2048 / 8 / 1024  =  900 MB


Second,File size comparison table about one hour one channel (unit: MB)

Note: The above is the theoretical calculation value, the actual video file size may have a certain deviation from the theoretical value.


Finally,Kindly find the attached Excel which can calculate any situation you want.
