# How many GB or TB is 1 hour of raw uncompressed Ultra HD film?

I was looking on wikipedia but couldn't find any definitive answer.

I think it's because it depends on how many bits is the color pallete and frames per second.

Please, could somebody help me make a rough estimate how much GB or TB would be a standard 24fps? or 30fps? (I am not sure which is the standard frame rate for UHD movies) Ultra HD movie (3840x2160) with the length of 1 hour.

I want to know the uncompressed raw size of the movie file after exporting from Adobe Premiere

I am not sure what is the standard 8 or 12 bit or some other? So, I will be thankful for your advice.

There are some storage calculators: AJA DataCalc, Video Space Calculator. Nothing complex, but keep also in mind that actual required storage size will be more than raw disk size due formatting, RAID levels etc.

• Thanks but here is digitalrebellion.com/webapps/video_calc.html only Redcode36 raw which gives me 126 GB. But that is already compressed. BTw. there is I think 42 which is compressed a little less, but still compressed. Any advicce where can I found a calculator that have uncompressed 4K option. On that site is 1080 maximum except redcode. Jan 13, 2013 at 15:04
• Try DataCalc: 1 hour/4K/uncompressed/10 bit + 2ch audio = 3,62 TB. Jan 13, 2013 at 18:20

A 'base' value is ~33 GB per minute for 8-bit RGB at 24fps. Multiply by 1.25 for 30fps, and/or by 1.5 for 12 bits/pixel, or 1.25 for 10 bits/px.

3840x2160 = 8294400 pixels per plane
x 3 for RGB = 24883200 px per frame
x 24 fps = 597196800 px per sec
x 60 sec = 3.5831808 x 10^10 px per hour
x 8 bits per pixel, / 8 bits per byte = 3.6 x 10^10 bytes / hour
So, roughly 33 GB per minute for 8-bit 24 fps

• according to this it is 1,6TB and not 33GB web.forret.com/tools/… Jan 13, 2013 at 15:27
• @Derfder: You selected 12-bits per color channel, rather than 8. You also selected interlaced, which halves it. Though he forgot that there are 3600 seconds in an hour, not 60; that's why his calculations are off. He's computed 33GB per minute. Jan 13, 2013 at 19:48
• Heh, this pops up again a year later. And yes, I slipped and computed the per minute size -- multiply by 60 to get the hourly rate. Jul 17, 2014 at 0:59
