First, The classification of Coding Rate(unit: Kbps)
Quality | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
CIF | 1536 | 1280 | 1024 | 768 | 512 | 380 | 256 | 128 |
HD1 | 1536 | 1280 | 1024 | 768 | 512 | 380 | 256 | 128 |
D1 | 2048 | 1792 | 1536 | 1280 | 1024 | 768 | 512 | 384 |
960H | 2048 | 1792 | 1536 | 1280 | 1024 | 768 | 512 | 384 |
720P | 4096 | 3072 | 2048 | 1536 | 1024 | 768 | 512 | 384 |
1080P | 6144 | 3072 | 2048 | 1536 | 1024 | 768 | 512 | 384 |
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)
Quality | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
CIF | 675 | 563 | 450 | 338 | 225 | 167 | 113 | 56 |
HD1 | 675 | 563 | 450 | 338 | 225 | 167 | 113 | 56 |
D1 | 900 | 788 | 675 | 563 | 450 | 338 | 225 | 169 |
960H | 900 | 788 | 675 | 563 | 450 | 338 | 225 | 169 |
720P | 1800 | 1350 | 900 | 675 | 450 | 338 | 225 | 169 |
1080P | 2700 | 1350 | 900 | 675 | 450 | 338 | 225 | 169 |
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.
