Local Media Storage Capacity
Each 60 minutes 512k call to RealPresence Capture Server requires about 450M storage (the 512k call raw
+ the default mp4 VoD). For 1024k, the storage space is about double, which is 900M. You cannot calculate
an accurate ratio because the size also depends on the video quality.
