Strorage Space Needed for Filming and Capturing 4K and 8k video

Here is a chart I've made based upon OUR OWN company's
storage needs after recording 4k, 8k and even 16k video using
single and multi-camera arrays. We use HUGE hard drive arrays
so we are able to do this calculation easily from ACTUAL real-world
recording experience with outdoor high-motion action video footage
which is hard to compress using 4:2:2 H264/MP4. We usually shoot
and EDIT in RAW and then compress to whatever our clients need
and want for final output.

For 8K video these are the storage space requirements
and if you want the 4K results just Divide by 4 on all the numbers:

8192 by 4320 pixels (8K 1.89:1 cinema aspect ratio)
at 16 bits per channel RAW (48-bit RGB colour Pixels)
and for H264/MP4 4:2:2 colour sampling at 10 bits
per color channel with typical 10:1 high quality
MP4-style compression) these are the following
calculated TYPICAL recording sizes for each frame rate
of 24 fps, 25 fps, 30 fps, 50 fps, 60 fps, 100 fps and 120 fps.

35,389,440 Bytes per RAW
RGB 16-bits per colour channel
or 48-bit RGB colour pixel video frame
at 35.3 megapixels per frame.

I hope this helps!

All I can say is that high-end video shooting 8K Uncompressed RAW
or 8K 10-bit 4:2:2 H264/MP4 take a LOT OF HARD DRIVE SPACE !!!

Remember! To get the 4K video storage space numbers,
just Divide-by-4 on all the above numbers!
