How long would you have to film something in HD to collect 1 PB of data?
To determine the duration required to collect 1 PB (petabyte) of data while filming in HD (high definition), we need to consider the data rate or bitrate at which the footage is being captured.
Let's assume the following parameters:
- HD resolution: 1920x1080 pixels
- Bit depth: 8 bits per pixel (standard for HD)
- Frame rate: 30 frames per second (typical for HD)
- Compression: Uncompressed (to simplify calculations)
To calculate the data rate per second, we use the following formula:
Data rate per second = (Resolution x Bit depth x Frame rate) / 8
Data rate per second = (1920 x 1080 x 8 x 30) / 8
Data rate per second = 186,624,000 bytes or 186.6 MB
Now, let's determine the duration to reach 1 PB by multiplying the data rate per second (in bytes) to reach 1 PB (in bytes).
1 PB = 1,000,000,000,000,000 bytes
Duration = 1,000,000,000,000,000 bytes ÷ 186,624,000 bytes per second
Duration ≈ 5,360,418 seconds
To convert this into hours, divide by 3,600 (seconds in an hour):
Duration ≈ 5,360,418 seconds ÷ 3,600 seconds/hour
Duration ≈ 1,489.0 hours
So, it would take approximately 1,489 hours (or around 62 days) of continuous filming in HD to collect 1 PB of data with the provided parameters.
