HUGE-SYSTEMS 1.5GB/s(!)

HUGE-Systems (www.hugesystems.com) have a new raid called 4440 that has a data rate of 1.5GB/s. That is enough for one 4K stream or two 2K streams (uncompressed).

It will be most interesting to see the RED-RAID and compare it with HUGE´s RAID solutions when it comes.

HUGE also have a system called 4210 (600GB/s) that is very interesting for 4:4:4 @ 1080P.

Well, this is build for 4k playback, but not recording. the 1600 MB/sec will drop to about 600 MB/sec when writing (RAID6).

The RED-RAID should be a RAID0 setup for optimized writing speed.
 
I know that the ability to record uncompressed 4k video is the holy grail of cinematography but I hope RED also develops a practical way to record a compressed version of 4k video.
 
Minimum performance is 800MB/s (at RAID 6). And why can You not record at RAID 0? Why do You need higher redundancy when recording?

That thing is sweeeet...

to avoid confusion that has already started, you dont need to run Raid 6 to write.. The Huge, and almost every single other raid system can be set to Raid 0.
 
Thank You for that clarification. :)

"That thing is sweeeet..."
Yes it is. My salivary glands is aching... ;-)
It will probably inflict some pain on my wallet too... ;-)

The problem with Raid 0 in this case is that the number of HDDs is extremely high. Even if the HDDs are reliable, there are 40 of them. If any one of them fails, the whole data will be lost.

This is in quite a big contrast of the Raid 6 operation where 2 HDDs out of ten can fail at the same time and still the data will be safe. When they came up with the idea of including 40 small HDDs in that system, I'm sure they paired that idea with the inclusion of Raid 6 as well to counterbalance the high number of disks. And together this is a brilliant system.

In my opinion if you are forced to use that raid system in Raid 0, you loose the whole point of that thing.

But recording compressed 4k that looks good enough to pass for uncompressed would be the holy grail of practical cinematography?
 
I think this is exactly where Red is missing a solution as things are now.

Now you can have the Red Drive which is capable of recording compressed visually lossless 2K video.

Or you have the Red Raid which is capable of recording 4K+ uncompressed video.

The second option requires much higher data storage amounts. Not only because the resolution is much higher, but because there is no compression.

You should provide an external compressor in front of Red Raid that could compress the 4K image in the same way as 2K is compressed. If you can store 2K on one single small disk, you could store the 4K video on only 4 small disks (still visually lossless). That would make an absolutely practical 4K camera.
 
"But recording compressed 4k that looks good enough to pass for uncompressed would be the holy grail of practical cinematography?"

How much does compression mess up green/blue screen work and color grading compared with lower color space?

What is to prefer? For example: 1:1 @ 4:2:2 or 3:1 @ 4:4:4 for FX when shooting? (assuming that the materials looks the same for the eye)

Very interesting idea. The horsepower needed to do this kind of computation would most certainly require an external unit as you suggest. Even if a unit like this couldn't be available at the launch of RED I imagine it would be a very useful product for those needing to shoot 4K.

Hopefully in the fall when RED releases footage they have extensive green screen shots that we'll be able to look at in the various color spaces and resolutions. Should be very interesting.

Personally speaking, I prefer slightly higher compressed RGB 4:4:4 than less compressed YCbCr 4:2:2, as long as both compressions are mild and visually lossless.

Thanks for the feedback though on my question!

I saw the Codex at NAB, was an interesting solution.

On the 4k 4:4:4 compression thing, i agree with Graeme, and usually 4:4:4 compresses (depending on the algo) alot better than 4:2:2 so squeezing a little more out of the 4:4:4 should result in a very stable image.
 
All this is "luxury concerns" when it is possible to pull a good (well at least decent) matt from from DVCPRO-HD via the Varicam and that is 6.7:1 @ 4:2:2.
As mentioned before, HDCAM SR is 3:1 @ 4:4:4 and it is good enough for George Lucas! :)
Can I have a Varicam for USD17500 AND S35 size on the sensor AND variable frame rate AND 2K AND 4K...it blows my mind! :)

If it is "only" as good as the Varicam I will buy it! Think of it. A Varicam for 17.500! I myself do not expect the quality of a HDC-950F from the RED...if it is, well then Mr Jannard will rub shoulders with the Lumiere brothers in the history books! :)

I expect it to exceed it.... Seriously. No reason why it shouldn't.

Sorry to travle offtopic but:
After making the last 2 Starwars (children) flicks - how can anyone say that George Lucas is about image quality?
Good enough for George Lucas doesn't mean anything after what he did to the original flicks..

Well, when you shoot 16:9 HDCAM and crop down to 2.35:1, I don't think image quality comes into it any more.....

ha ha ha.. that got the first laugh of the day from me :)

Only good thing about going to 2:35:1 from HDCAM is with a fixed rate 8 pixel macroblock compression algorithm, it allows for better compression in the actual picture area.
