Calculate video size
HD Output HDMI (1920*1080)
I would like to find out how big a file size of one hour of recording. It is a CCTV with 960h resolution. I am thinking of buying a 500 Gb drive to store the video. Thanks. |

That greatly depends on which video encoding type, encoding video quality, and other encoding parameters. IMO, an enough quality for a 1080p video encoded using H.264 would use about 2500kbps bitrate. An hour video would be around 900MB. Better quality would require larger bitrate, thus larger file size. |

Thanks. I presume there's some reason why you haven't just tried it to find out? (Perhaps you haven't bought the CCTV yet. But you could record something from a similar-resolution source, to get some idea - a minute's worth should give a ballpark figure. Plus, you could experiment with various encryption and encoding algorithms to see if any give unacceptable results.) -- J. P. Gilliver.

I have not got the cameras, but they are in the mail. I originally bought a 720p, but there were out of stock. They are instead sending some 1080p as no extra charge. :-) I am also expecting a 1/2 Terrabyte h.d. as well. Andy Andy |
