  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Video - GTX 480 performance in Adobe Premiere Pro CS5

My SSD is 200+ MB/sec read. That's faster than my 5 disk Sata Raid 5.

Thats a very very slow RAID. Its not just about the data rate of the stream, its the data rate available for CC layers etc etc, you will not get smooth full res playback off of anything except a fast RAID, yes 1/4 or 1/8 but not full res.

Jay,what would you consider a fast raid,or fast enough?
 
i thought a fast raid would hit in excess of 700mb/s + or im just talkin outa my butt. as far as i can tell my system will edit scarlet footage flawlessly and for 2500 bucks. thats not a bad deal.
 
You can build a 700 mb/s RAID 5 for about 1500 dollars. Thats the start of what I would call a fast single array, its not fast at under 500 mbps in my opinion, for the investment in a RAID you should be getting at least 500 out of it, unless its an Xserve RAID which was designed to be used in large quantities for speed not individual arrays. I have built and bought hundreds of RAIDs and 500 is the least you should be looking for.

For editing i'd recommend (Personal use) something that will push out about 600 mbps because it can be done on a budget, if your looking to color correct, edit, conform, grade etc on a single system, try and get around 750/800 out of a RAID it will actually pay off the investment in the amount of time your not waiting for the bottleneck, and also allows you to do all the above in higher quality thus lowering the chance you have of not passing QC.
 
PCI-E for sure with something like an Atto R380 can push 800mbps

with some high density 7200rpm drives like the 7200.11 in 1.5 TB

in a SAS Expander chassis like something from ProAvio or similar (Hundreds of options)

Comes in at around the 1500 mark or so I think. Just off the top of my head, theres other options at higher and lower cost too. The above solution is one of the most popular ways of getting a fast raid at a good price though.
 
Or also, I don't really like recommending it for the PC platform as I have never used it on a Windows system I use the Caldigit RAID card and HDElements for client systems a lot. Great pre-made out of the box and it works system. But ((DISCLAIMER)) I have only ever used it on a Mac Pro system never a PC so I'm not sure of the performance.

I don't really understand why 1/4 would play smooth and full rez would not based on hard drive speed. Isn't an R3D an R3D and coming off the drive at the same speed regardless of which resolution you're decoding to?

RED is only 36MB per second. Seems like any modern hard drive will play a single layer of that at full rez just fine.

Can anyone with a REDrocket confirm that?

It's worth remembering we're WRITING REDCODE RAW to a couple laptop drives in a RAID hanging off the back of the camera.

My tests indicate the bottleneck is CPU and not hard drive or ram. The GPU is handling all the CC and FX I can throw at it. That's got nothing to do with hard drive speed.

Yeah, I've got a "slow" 5 disk Sata raid that does 150MB to 200MB per second that cost me $350 plus drives to build. Actually I can add more RAID enclosures for $200 plus drives each. For typical narrative editing I haven't seen a disk speed problem yet. (admittedly, typical narrative isn't usually stacking many layers - so it's really easy on hard drive speed)

Now if you're doing uncompressed editing - sure you're going to need a Caldigit. I'm skeptical most people need that kind of speed. REDCODE is a very compressed raw codec that is a MOTHER to decompress/debayer - but that's a CPU thing.
 
keep in mind his intent is for the future with scarlet footage, which will be way over 30-42 mb/sec. a fast raid set up will offer more streams, multi cam etc. you're right about the debayer process being limited to the CPU, but eliminating bottlenecks wherever possible can only benefit the workflow, it won't take away from it. Hopefully rocket support will come to premiere soon and we are looking at a complete r3d workflow being cut together like it was dv25...

You'll still have the option to record at 28 or 36. My attitude was/is I'll start with a simple, inexpensive RAID and upgrade when it's clear I need to. I haven't needed to yet. We'll see what EPIC and 5K bring. I'll test the different data rates. I'm guessing it'll be 42.

Sure it's easy to advise buying all the most expensive stuff. A lot of people here like to do just that.

But I think a lot of people have to allocate their money very wisely and want to know where they can start. That's a much more challenging thing to answer. I'd tell 'em to throw down on a CPU and a good graphics card first. And probably better actors after that. :-)
 
Ya I just bought the 480 and 6gb more ram. I don't think il be able to use it to its full potential unless I drop a grand on a solid raid setup. But I'm guna hold off on that until scarlet is released. Right now my system is used for editing accurately which it handles without issue. So I'm good to go.
 
you sound pretty good for now, and as storage gets cheaper, and in higher capacities, you'll be good to go for scarlet release. the advise was mainly for what you should get for massive r3d files, and wanting to be able to cut it like butter at higher playback settings. I personally can't afford all the biggest SAS raid setups and so on and so forth, wish I could have it all, but rent and food supersede all that :)

But your setup as is now is pretty rockin, and yeh, cheaper solutions are in order for your current workload. But like any workflow I like to have to best combination of performance, capacity, and safety. So a decent raid 5 is something to look at more than the heavy duty monsters until you feel like that current setup just isn't doing it for you anymore.

I don't disagree with you at all Joel, and fortunately there are tons of options for every workflow. And a bad actor can easily destroy any workflow...

I think your issue with Red playback is insufficient system RAM at 6GB. Plus, Adobe recommends a minimum RAID 0 of a pair of 7200 rpm drives for high data rate footage playback...

Adobe's own 64-bit document recommends 32GB of RAM for working with Red 4K footage, which requires a Server or Workstation motherboard...

Maybe somebody out there can confirm this?

I have system with this spec:
2x(Xeon x5550)
48GB Ram 1333 ECC Reg
Quadro FX 3800
MB supermicro X8da3
1X300GB SAS HDD for OS and Programs
3X1.5TB 7500 RPM RAID 0 for Projects

OS Windows 7 64bit
Adobe CS5 Master Collection

and it's trouble for 4K footage!!!!

I've called Adobe tech support about the exact system configuration needed to run 3-4 streams of Red 4K footage with effects as in the demos, and I get nothing but a runaround with no specifics, quite disappointing for dropping thousands to get Master Collection...

Only two things that might seem might be at issue for you Mohammad are the speed of the RAID 0 you have, and the CPU speed- I keep hearing overclocked desktop CPU outperform the dual server CPU's, but that of course limits the RAM available for After effects to 24GB... That, plus not "everything" is accelerated, so YMMV depending on your expectations for Premiere Pro and After Effects...

So far, I'm not happy with Adobe's response...
