4k calculator- what's the easiest way to find out how much storage you need

[juanito bandito]

I am sure there is some info out there, but I am trying to find out if there is a guide or a calculator to estimate how much storage I would need for a shoot? I am looking to figure out how much per minute on average.  I know it depends on bit rate, etc. but has someone figured all of that out?

The FujiFilm specifications give you a rough estimate:

The calculation is:

Take the bit rate , multiply by number of seconds , divide by 8.

For 100Mbps that would equate to 750MB/minute (i.e. 100 *60 / 8).

Double for 200Mbps and quadruple for 400Mbps.

So for 4K at 400Mbps you will be using roughly 3GB per minute.

The camera doesn't always use exactly the specified bit rate but this gives you an approximation.
