Quick fix if it works:
Unhook your internet cable or aluminum foil your wireless antenna until there`s no talking there.
Remove the Intensity Pro then uninstall any of it`s programs in the programs bar as regularly as possible.
Reboot the box once or twice.
Borrow another type of PCI-e card to stick in the same slot and it`s software if it`s around.
Then install the software if you have it,-
then remove the disk and put the card in the slot and finish it`s installation.
Then remove the card and uninstall that software, original or Windows type.
Reboot the computer, you might be clear now to do a good installation of the Intensity Pro.
One also checks the setup bios settings to see if the Intensity Pro`s software was installed and the card detected in the first place, then the computer disabled them in the first reboot because the PCI-e slot was set to be turned off in the first place.
Otherwise it sounds to me like prepare for the usual data surgery.
-Just a quick and dirty guess and try that might work.

Do all of the above but some of us have partly wooden vans and a serious start on you! If you`re near water see if some boat builders have spare wood and metal struts you can laminate.Your cutting and drilling tools should have harder cutting surfaces than what they`re digging into, and sharp.

Assuming you`re not using your production computer as a, the, typical internet beast you should actually see no problems at all. Backing up the data from the new drives, even if on borrowed maedia, is the safer than safe, safety step you can use. You`ll be able to swap those Raid sets endlessly, just like you wish.

[Fred Jodry]

Since you have “9 terra bytes of storage and ever expanding”, you`ll be heading for Raid 5 not Raid 1 or Raid “0 + 1”. You don`t have to check out much of the rest of the internet, the Cow and it`s advertised products, software, and advice is rather full and has had a steady load of it since late February. Look and see that you have a full battle plan for stepping into the future, like not neglecting (incremental? manual?) backup and restore software if it`s something you need. My own boxes have “oversize” custom air filters on fan inputs to keep them clean without overheating them. I can`t see anything described outside of stepping up to a regular Raid box array except that it seems as though you`re saying that filling and uncabling hard drives is one of your ways of storage. It`s a good one. One thing you should do whether to mention those unhookable hard drives, or the ones in the Raid box, is try to pick hard drives that can be bought in identical batches, and that even have swappable circuit board cards in them for the furthest reaches in data rescues. “9 TB and ever expanding” sounds like a regular description of needing to “back up” data in two types of storage. Have you planned- in an uninterruptible power supply? It sounds like you`re on your way, just get a good night`s sleep (one that makes it all the way to your brain) and include pencil and paper in the things to pack for the trip. What`s your specific use? Some uses like banking or web serving have different stresses than the usual video or audio production that we usually see here. Ah! HD video storage. OK, regular.

[Fred Jodry]

Usually the computer setup just sees the returning Raid drives as a detected partition (or a couple of them) and you`ll soon be rolling. It`s only if software updates, new software, or viruses, go attacking that you have problems, and in these cases it`s the usual, big computer, little you. If the Raid drives are subjects of an Operating System drive, then you drop them back in, detect them properly and there`s certainly the possibility that there`s little or no trouble. If the Operating System was installed (split?) into the Raid drives then you should roll the clock (date) back in the setup of the computer to barely later than their retirement`s date and re- introduce them the easier than easy way. If you made the mistake of putting your production computer on the internet and antivirus programming it (with the old Raid in use) then you`re usually in for the big surprise of a big attack from maybe both antivirus software and viruses, so you`ll be reaching for the help of the usual data rescue business.

[Fred Jodry]

Sachin, Bob`s advice esentially trumps mine in that he`s already done the stuff and knows much more about the data horsepower. However I`d still recommend that you use a Raid 1 setup. Fortunately it doesn`t need 3 or 4 equal “editing workspace” hard drives, only 2 of them because it`s Raid 1 not Raid 5. Buy a small nice (deluxe) Hitachi or similar hard drive for the non-Raid operating system hard drive and you`ll have one of the 2 TB hard drives around as a spare “workspace” drive. Save some wallet`s money for what goes out of tweak someday.

[Fred Jodry]

If you fire your DeckLink HD Extreme 3D up to full tilt 3D (stereo pictures) input and editing, then 206 MB per second Raid 5 will crash and probably corrupt from low data horsepower. Unfortunately if you try to run your 6 GB of data real estate without growing a single Dandelion (that`s Raid 0) in between all those Raw Audio Video takes and Raw Audio Video Edits asparagus, you`ll be in for a bad surprise of weeds really soon. You can use your 2 TB each hard drives as Raid 1 backup projects amongst other possibilities but you`re in for a surprise just how many hard drives you`ll need running Raid “0 + 1” or Raid 5 that you`ll need next to a deluxe controller card that tells the rest of the computer that here`s a good place to go taking and editing, even rendering. Raid 0 is sensible for small hard drives and economy (redo-able later) takes, not main load professional uses. I`d might as well let the other Engineers chime in on general recommendations but at least what (array) you`ll next buy can be seen on your right or left. Are you making regular flat one eye HD tv, or 3D 2 eyes HD tv?

is Mac Pro RAID Card really capable for video
by Sachin Desai on Apr 24, 2010 at 10:34:41 am

Hello!

I’m planing to buy a new mac pro with following configuration

Two 2.26GHz Quad-Core(8 core) Intel Xeon “Nehalem” processors
6GB (six 1GB) memory
640GB hard drive1
18x double-layer SuperDrive
ATI Radeon HD 4870 512MB DDR5
DeckLink HD Extreme 3D as edit card
2TB x 3 HDD = 6TB with mac pro raid card

now I want to edit 10bit uncompressed HD 24P 1920×1080

is this mac pro raid card is capable of editing the 10bit uncompressed hd footage

i read the mac pro raid card data streams and with sata raid 5 is giving 206 mbps.

I believe if I make Striped RAID 0 it will give me much faster if i’m, not wrong.

please advice should i proceed with this configuration??

thanks

Jeff, Alan is setting the background ranges of the (knobs?)on his MONITOR (cathode ray tube display or similar). Anything that works and still leaves range for adjusting works, just like a tv. When it comes to making video in the first place, Both NTSC (National Television Standards Committee) and NTSC 2 (color tv committee around 14 years later) made the black pedestal 7 1/2 IRE units above zero, the positive plateau of “untilted” synchronization pulses. 5 to 10 IRE are accepted limits and can be seen as reasons of gamma correction or simply acceptable error. When making NTSC video that “goes somewhere” in this world, use it or you`re out of specifications for the composite signal. RGB lines going out of a camera head towards the combiner or encoder are examples of zero pedestal black uses and not the composite signal yet. Which pedestal and voltage gain he uses depends on the part of the operation. If we read Alan`s inquiry again carefully, I seem to remember that he`s asking about an RGB- style input, maybe Pr, Pb, Y, where Pb and Pr probably have zero pedestals compared to clamping but can maybe, maybe go both positive and negative of it, and the Y signal probably also has a zero pedestal but only goes positive. Pb, Pr, Y is really a mixing level brought up to annoy red, green, blue, (“already mixed” spare luminance, like keying etc.) and synch. cabled video users. SMPTE is a modern committee or really an engineering society.

After I`ve done a full reinstallation of software, sometimes I make a few folders and load a stack of DVDs in them with no intention of using them. Later when fragmentation bogs things down I empty the folders and use them or their space for work. This is no big trick but it does let me “lose some steam” at will if the fragmentation gets too bad.

[Fred Jodry]

Alan, since you are using standard output instead of one for Beta, the N10/ SMPTE one is the standard to use on the monitor when running NTSC, and in some other cases. Now let`s look at the trouble you weren`t going to get into:
In point of fact, since you are feeding a display monitor and looking at it you can probably make a proper display on the screen, both background brightness and acceptable drive, by adjusting within the reasonable range of the brightness and color/contrast “knobs?” on the monitor as you use any of the 3 settings. (If the brightness range on your Sony doesn`t have a wide enough swing, break out your circuit diagram and soldering iron and get to work.) The real test is not whether the Intensity Pro`s output looks right on the monitor, which it will usually pass even if it`s wrong in certain directions but how it looks on the oscilloscope. Feed properly adjusted color bars or other test signal input into the Intensity Pro`s recording then feed out the playback to a properly terminated oscilloscope (which can be in line with the monitor and whatever else is getting fed) and look for proper signals on the oscilloscope`s display. A good stored test recording can substitute. You`re then set up and ready to monitor your camera or similar.
Below, is a list of voltages for color bars as Pr, Pb, and (Y?) for N10/ SMPTE.

“Their (color-difference signals) amplitudes are expressed in percentages of the full amplitude primary signals (700 mV). These signal amplitudes are reduced by scaling factors to meet specific signal amplitude range requirements. When the allowed amplitude range of these signals is 700 mV (±350 mV), as specified in the EBU N10 Standard and the ITU-R BT 601 recommendation, the color-difference signals are given by the following expressions:

E´CB = 0.564 (E´B – E´Y), also known as PB in North America
E´CR = 0.713 (E´R – E´Y), also known as PR in North America”

Intensity Pro analog component output type
by Alan Okey on Apr 20, 2010 at 9:15:57 am
I’m monitoring the component analog output of an Intensity Pro (downconverted to SD-NTSC) on a Sony PVM-20M2U. The monitor has a choice of three different settings for Component Level:

N10/SMPTE
Beta 7.5
Beta 0

Which is the proper setting to use for monitoring component analog SD (NTSC) from the Intensity Pro?
