Hardware improvements for fcp ?
I have recently started working with fcp and my computer is happy for about an hour before it grinds almost to a halt and I need to restart. I have a Mac Pro Quad 2.8ghz with 6gb ram and an ati radeon hd 2600 xt. Is there anything I add to this system to make it work for longer and more quickly ?
Thank you !

Would you mind explaining RAID as I don't know what this is. Thanks.
A RAID is when you take several hard drives and "stripe" them so that machine connected to them sees them as one drive. There are several iterations possible. Like RAID 0, RAID 1, RAID 5, others.
RAID 0 = the fastest setup, least secure. Zero redundancy. If one drive fails in the RAID you lose it all.
RAID 5 = slower, redundant safety. If one drive fails, you pull it out, slide in the replacement and the computer will re-build the data for you. A RAID 5 scenario requires hardware.
You can set up a "Soft RAID" RAID 0 right now, if you wanted. Soft RAID = software only. Not controlled by hardware. Or you could get a card to do a full hardware RAID setup.

Optimal Hardware/Software configuration for FCP
I switched from PCs to Macs about 1/2 a year ago to due overwhelming frustration at numerous Windows crashes. I have used Adobe Premiere Pro, Audition and Encore on a PC desktop to do video projects. I now have a 17" 1.67 Powerbook with 2gb of ram and the FCP suite. On a Windows PC, I tweaked everything to get the most out of the computer, partitioned a drive for the video projects, did regular defragging etc etc.
Now that I am on a Mac, I am not sure what needs to be done and what doesn't. I have an external 320 gb Firewire 800 HD that has my iTunes library, some backup files and will be the drive I use to capture video to and edit from. The drive is not partitioned. I have read that partitioning is not really necessary in Mac OS as the file management is much better. I would like to partition it anyway to make a small boot drive in case the hard drive on the Powerbook fails. Is there any benefit to partitioning a drive for video/sound files for FCP projects?
Any other suggestions would be greatly appreciated. I haven't found much information on system optimization for FCP.
Thanks,
Philip
17" 1.67 Powerbook Mac OS X (10.4.3) 2gb of ramCreating a back up system drive is a really good idea and it makes sense to partition your external drive to organize things. The other option is to just purchase another drive for that purpose.
If you want to back up your system, Carbon Copy Cloner is a great app.
There is a very nice program called Volume Works which will do partitioning and resizing partitioning on the fly. Very useful if you like to use partions as a way to organize system drives and media on the same disk.
Since the Mac OS is essentially Unix at the core, it was designed from the ground up as a robust 24/7 OS. There are maintenence things that need to be regularly run ( called CRONs) and there are other disk file and directory maintenence activities listed below. Other than that, if you REALLY enjoy getting down with text based interfaces and mucking about you can find all sorts of folks who are tweeking the system - for example - moving the location of the system swap file on the system disk. Not for the faint hearted...
General things to do ...
Repair Disk Permissions
Repairing disk permissions is simply good system maintenance and should be done as part of ANY upgrade and/or application addition. In addition it should be run regularly just as a preventative tool. It makes sure that the permissions on application files are set to the read/write/execute permissions they should have. Sometimes these are changed through the addition of new/updated programs which can cause varied and difficult to track down problems.
Verify Directory Structure
Disk Warrior is a file directory repair/optimization program. It analyzes and repairs your disk directory structure as well as optimizing it. It will pick up and repair problems that the OSX included Disk Repair Utility can not address. It is an essential tool.
Run the Cron Utilities
If you leave your machine on 24/7 these ought to run on a regular basis. If you turn the machine off at night (or, are like me - during the day - vampires anyone?) you want to force these crititcal utilities to run. Download and run a program such as OnyX which gives you a number of options regarding CRON, flushing caches, prebinding (aka optimizing) dumping log and temp files and so on and so forth.
Down load and have ready to run the application FCP RESCUE. You can find it on Versiontracker. It is another one of the those really useful tools. It deletes all your preference files when they become corrupt. Once the system is working again and set the way you like it, it will back up the same files so the next time things go south, you simply overwrite the corrupt with the good -sounds like batman doesn't it...
Take care of your machine and it will take care of you!

Please help me configure a new 8core for FCP
PLEASE HELP A PC GUY MOVE OVER...
I need to configure a new 8-core for FCP mainly. I need to keep the expense reasonable so dont want to spend extra $$$ if i dont have to.
I edit files from many different camera's these days. Mostly weddings & demos.
I want to go with an 8 core either Two 2.26GHz, OR 2.66GHz? Is the 2.2 fast enough with FCP?
How much ram do i need?
Do I need to stripe 2 sata drives together for the video?
Which video card?
Can you recommend any other software/hardware that will help me?
Here is a link to apples spec page:

Either will work fine.

As much as you want but 8G will be adequate. More might not help significantly.
sarecco wrote:

Depends on the video you're trying to use or if you want to do 9 camera multiclips. Maybe.
sarecco wrote:

The stock 4870 is the gold standard for Motion; the current rev of FCP does not care much about the GPU but we are hoping future revs will use the card directly.

Umm, withotu knowing what you need to do, of course not.

No sweat, ignore those other guys. We see this post about once a week around here so you can easily research it on the forum. Strongly urge you to locate your local Macintosh user group.

Please have a look at my system and give me ideas how I could eventuially improve it.
regardsI agree completely with Harm. A 550W PSU of average (or middling) quality like the one that you have (which, by the way, is based on a CWT PSH or PSH-II platform) is not quite enough to power a power-hungry CPU like the i7-950 of yours, especially if a better-performing GPU such as the the GTX 560 Ti that Harm suggested is added along with two or more additional hard drives. (Your system currently has exactly two hard drives, which is the absolute minimum that you should have in an editing system unless you want performance to be slower than an old Pentium 4. However, one of those hard drives spins at only 5400 RPM - far from ideal for an editing system. You really want all of the hard drives inside that system to spin at 7200 RPM.)
Speaking of the GTX 560 Ti, you don't need the one with 448 cores since a non-overclocked (read: stock speed) i7-950 can't take full advantage of that higher-end GPU (and please note that the GTX 560 Ti 448 is actually a GTX 570 with one of its shader units disabled whereas the standard GTX 560 Ti is a different chip altogether). The standard GTX 560 Ti, with its 384 CUDA cores and a 256-bit DDR5 memory bus width, would suffice. However, if you do wish to overclock the i7-950 (to at least 3.8GHz), then the 448-core edition of the GTX 560 Ti would make more sense. (The 9500 GT that you currently have is not only old, it's slow and weak as well: It has only 32 CUDA cores, and it uses really, really crummy DDR2 RAM with only a 128-bit memory bus width. Such a card would have made the GPU-accelerated mode significantly slower than software-only mode during certain operations within CS5.x.)
By the way, I was wrong six months ago about the Dell systems sold during Fall 2011 that came with a 1.25GB version of the GTX 560 Ti: I had assumed that that card had 448 cores. Well, I did more research, and discovered that there was an OEM version of the GTX 560 Ti which did use a 320-bit DDR5 memory bus - but it had only 352 CUDA cores. It uses the same GPU as the GTX 570 and GTX 580, but with only 11 of its 16 shader units enabled, making it a GTX 570 with four of that GPU's shader units disabled. The Dell version of the GTX 560 Ti is, indeed, only a 352-core unit that was based off of a GTX 570. That made the Dell GTX 560 Ti expensive for what it is - at around $300, it cost as much money as the 448-core version of the GTX 560 Ti sold for around that time. -
Magic stable OS X + QT combo for FCP
I'm self-moderating and moving this from a different thread:
I just ordered my Mac Pro and will be sticking with FCS1 (FCP 5.1.4) for now. I will be doing a fresh and squeeky clean install and want to make sure I have a rock solid system from the start.
Shane Ross wrote:
Magic Combo for FCP 5.1.4:
OS 10.4.11 or 10.4.10
QT 7.1.6. 7.3 also works fine...but 7.1.6 is solid.
What about using with OS X 10.5? I'm looking forward to the OS upgrade which comes along with the hardware.Zebulun wrote:
Do yourself a favor and move to FC Studio 2.
Is that an offer to cover the cost?
I very much want to move to FCS2, I don't need to be talked into it at all -- but it just is not in my budget at the moment. I've already sunk into as much debt as I can handle with the machine upgrade.
Zebulun wrote:
Shane is right with those versions. Do a bit of searching and you'll find folks have problems with QT 7.4.x and FCP 5.1.4
I actually haven't had any issues at all running FCP 5.1.4 with QT 7.4.1 on OS X 10.4.11. So, I guess I'm one of the lucky few. -
Low cost Mackie control surface for FCP 6?
Could someone recommend an inexpensive control surface for FCP 6? Perhaps a bit more expensive than the Berhinger but cheaper than the Tascam.
I've had nothing but grief since installing the FW-1082 and sure could use some help when you return. Here is my current situation (copied from my post on the TASCAM forum which yielded zero responses):
I know the instructions say that the FW-1082 should be plugged directly into the computer interface and that nothing should be plugged into it. Unfortunately my Intel iMac only has one FW400 and one FW800 port. There are other FW400 peripherals such as HDD's and camcorder video capture. With only one FW400 port, it means either I plug the FW-1082 directly into the computer and then connect the FW400 hub to the second FW-1082 port, or plug the hub directly into the computer and the FW-1082 into it. Which ever approach I use, it results in very unstable operation. Sometimes the 'Firewire' LED never lights. Other times the FW-1082 keeps reseting itself every few seconds. Unfortunately I no longer have the option of returning it, so I must find some way to use it with my existing hardware.
I just installed V1.06 of the Mac drivers and 'Fix for Mac OSX 10.4.10 FireWire' from the TASCAM website, restarted the computer, and now the Firewire LED on the FW-1082 never lights. The 'fix' mentioned above rolls back the extension 'AppleFWAudio' to V2.0.1. to resolve a problem with the OSX 10.4.10 update. Unfortunately, I don't know how to restore it to its previous state. Help!
(I apologize for posting this in the FCP forum, but this is the only place I've been able to find fellow FW-1082 users.) -
Not sure which Mac to get for FCP/Avid... Input much appreciated
Hello,
My question is...
I work in television production and I am making the move to get into editing and I plan on purchasing a Mac in the next few weeks, and I am looking for a bit of advice.
Basically I would like to run FCP on the Mac, and if possible I would like to be able to run a version of Avid Express. The projects that I will work on at home will probably be run through FCP, but if possible I would like to be able to install some version of Avid on the same machine to help me learn.
My main question is... I actually have a television that I purchased about 2 1/2 years ago that has an easy option to use it as a computer monitor, and first off I would like to see if you can tell if this will work for a Mac Pro... Secondly, would it make more sense to shell out $2500 for the Mac Pro and use my existing monitor, or should I go with an Imac and not use my monitor. Basically I would like to know if there is a major difference between a low level Mac Pro and a higher end Imac. I am just a bit uncertain what would be the best way to go. My limit would be $2500 but I would really like to keep it around $1700.
I am not sure if my tv/monitor can handle graphically what would be done so I have included a link for the model that I have.
Any input would be appreciated.
Westinghouse LTV-27W2 27" Widescreen Progressive-Scan LCD TVYou might - just - get a Mac Pro for $1700, if you bargain-hunt, but bear in mind that you'll likely need to upgrade the RAM, and certainly get hold of a decent amount of HD space for your media and renders for both programs. Check lowendmac.com regularly - they have a good range of vendors with used and refurb models.
Avid no longer sells Xpress Pro - it's all Media Composer now. Note that Avid does have very specific hardware requirements for supported systems. Not even every Mac Pro is supported (which doesn't necessarily mean it won't run, but you may have problems with it). Pay close attention to which graphics card you're getting, and check that table. Also, Media Composer requires specific versions of OS X and Quicktime, so you'll either have to settle on one system (and avoid Software Updates) or have different systems (eg, two partitions) for the two programs.
Your television has a DVI input, which will work fine with either a Mac Pro or an iMac. Note that Mac Pros still have one DVI port; for an iMac, you'll need the separately-sold Mini DisplayPort to DVI adaptor. Either way, it will be fine for video editing.

Hardware Requirements for OC4J and Oracle DB
Hi,
I'm looking for some information about hardware requirements for a server that will run a Oracle DB and OC4J. It will be used for training purpose (about 10 people) and for running small apps using ADF.
Does anybody knows how much hardware I need?
Is there any documents from Oracle for hardware requirements?
Any help appreciated. ThanksGreetings,
We routinely develop and test on a Dell Vostro laptop with OS Windows XP and 4GB RAM. The key is to either run the Oracle db in a VM (10.2.0.1) with at least 0.5 GB RAM for the VM or use the XE db. I personally prefer the XE db as it is lightweight and easily configured or uninstalled. As far as oc4j is concerned, a lot can be done to improve the efficiency by modifying the oc4j.cmd file in driveletter:/oc4j/bin:
set JVMARGS=-Xmx512m -XX:-UseGCOverheadLimit -server -XX:MaxPermSize=256m -Dclass.load.trace=class-not-found -Dclass.load.log.level=finestThe JVM args settings are fully explained at:

Hi Guys
Can anybody tell me what is the correct way to set up a raid card and scratch disk for FCP if you have 3 x 2TB internal hard drives, with the OS on HD1 and drives 2 and 3 dedicated for FCP
Also with this i also have all my documents i.e work stuff, invoices, pictures, music ect from my old windows PC and used to have them stored on HD2 with the Windows 7 OS on HD1 - i have been told that it is fine if i put this on the same drives as FCP is this correct...?
i only ask this as i have been told how to do it in different ways by 3 people......Thanks John, although i'm rather embarrassed to admit that I am a complete newbie when it comes to technical/computer hardware terms (i.e. I have no idea about different types of disks, other than a HDD and a SSD, or even what the difference is between your media cache and a scratch disk).
This means that after reading all the links you so helpfully provided hasn't done much other than making me feel even more stupid!
The best that I can conclude from what I think that i've understood is that I will use:
Intel 530 Series 120GB SSD for O/S, Programs (and Pagefile?? No idea what this is, sorry)
Samsung 840BW 500GB - Scratch Disk (is this the media cache?) and preview
Seagate Barracuda 3TB HDD - media, projects, and exports
Please tell me if i've got something around the wrong way....
Thanks again. -
Have a 3.06GHz intel core 2 duo for FCP?
I all... I have a 3.06GHz intel core 2 duo IMac that I'm using for FCP.
At 3+ years old, I'm wondering if it's time to invest in a new Imac?
GHz speeds haven't gone up by a lot but I have to believe that speeds have?
Are render times in FCP or Compressor substantially improved to justify this purchase?
Thanks so much for your help!
- BKIf you want flexibility then consider moving up to a mac pro, that'll give you a solid base for a performance boost. Unless theres anything wrong with your current machine, you might want to wait a month or so and see what kind of horsepower the new version FCPX plays best with.
cheers

DVD Footage for FCP Edit - how to tell if NTSC or PAL?!
Hi all, apologies if this seems like a stupid request but I have a job at the moment calling for me to extract footage from a DVD, edit in FCP, add a few bits from Motion etc., but I can't work out if the DVD is NTSC or PAL!
I intend to extract the video (no issues with copyright) via DVDxDVPro but am unsure if the DVD has been encoded in NTSC or PAL. The footage it contains is from both the States (NTSC) and South Africa (PAL) so how do I tell? I don't want to go through a standards conversion if I can help it.
I am keen to try to retain as much quality as possible (client can't provide tape) so also any thougts on the best output from DVDxDVPRo for FCP editing?
Thanks all,
Best wishes
MichaelHi Thomas, that's it!
Thanks for this - it clearly shows the TV standard and the resolution plus 4:3 etc., so everything I needed for confirmation.
Glad I cheked because it was in Pal - thought the conversion in DVDxDVPro looked a bit ropey.
This realy baffled me - seemed so simple but couldn't find a way to tell the standard. Learn something everyday...
I am using DVCPro for export from DVDxDVPro - anyone thoughts on a better option?
Thanks again for the answer - and so quick on a Sunday too!
Kind regards

I keep getting this screen and before I have to call and pay and wanted to see if there was something that I could do.
Pavilion dv4-1123us get blue screen with "hardware malfunction call hardware vendor for support"
This question was solved.
View Solution.I would say its just a conicidence and recommend you to do a system restore. As its an intermittent problem, you never know if you face same issue once again.

DO i need some extra hardware interface for receving both Audio and video
hi i m doing e-learning project. i have to capture video from webcam and voice from headphone and send to client.
but my code is working fine for either one at a time.
DO i need some extra hardware interface for receving both Audio and video. im using code AVTransmit and AVReceive found from this site only
After running TX
i give Dsound:// & vfw://0 in Media Locater only sound is received and no vedio
and when i give vfw://0 in Media Locater only live video is transmited.
im using JMF1.1.2e.
if any one know the method to run or cause of it plz reply me soon. i will be very thankfull
transmiter/server side code .first run TX on server

HT4480 I have redemption codes for FCP from my university - how many machines can I install on?
I have redemption codes for FCP from my university - how many machines can I install on?
Do you have these codes because this will be your app? Or is this a "loan" from the school to install on your machine? Do you use your own Apple ID to redeem the code and install the app?
If it is your app, then you may install it on as many Macs as you own or have in your control.

Nuance Dragon PC and/or Mac on Intel Macs???
The Nuance advisory relative to system requirements is that Dragon Dictate works on any Mac with an Intel processor. A rep I spoke with at Nuance, assured me that this is the case and applies to booting into Windows on a Mac to use Dragon Naturally.
