Question 147831
I'll take a shot at it.
26 frames/sec x 60 sec/min = 1560 frames /min
there are 1600 x 1200 pixels/frame, or
{{{1.92*10^6}}} pixels/frame
1560 frames/min x 1920000 pixels/frame = {{{2.9952*10^9}}} pixels/min
Each pixel is in {{{x}}}-bit color, so
each minute of video requires {{{(2.9952*10^9)*x}}} bits/min
The hard drive is {{{80}}}GB
80 GB x 1024 MB/GB x 1024 KB/MB x 1024 Bytes/KB x 8 bits/Byte
So the hard drive's capacity is {{{687.19477*10^9}}} bits
The number of minutes one can get out of the 80 GB hard drive is
{{{687.19477*10^9}}} bits / {{{(2.9952*10^9)*x}}} bits/min
{{{T = 229.432 / x}}} min
If {{{x = 32}}},
{{{T = 7.1697}}}min
That isn't much time. Maybe I goofed, but I think
my method is OK
