How many minutes of video can I store on my HD?

18 minutes of uncompressed UHDV footage consumes 3.5 terabytes of data and 1 minute of footage consumes 194 gigabytes. If 1920×1080p60 high definition video has a bitrate of 60 Mbit/s using current MPEG-2 compression technologies, then 4 times the width and 4 times the height will roughly require 16 times the bitrate. That would translate to 100 GB for 18 minute of UHDV, or 6 GB per minute. This would mean that a 12cm Holographic Versatile Disc at 3 micrometer separation of different colored tracks (with a capacity of 3.9TB) would be able to store roughly 11 hours of MPEG-2 compressed UHDV, compared to the 18 and a half minutes of uncompressed UHDV. Additionally, an eight layer Blu-ray disc (with a capacity of 200GB) would be able to store approximately 36 minutes of MPEG-2 compressed UHDV, compared to the 1 minute of uncompressed UHDV.
