Im newbie in color no matter in FCP nor COLOR. Thanks for help guys

What is this footage that you are trying to color? The hardware used really doesn't matter in this case, all they are doing it outputting a signal to your monitor. How that footage looks and how far you can push it isn't dependant on the cards...it is dependent on the footage you have to work with.
I know your English might be poor, so I hope you don't get lost.
Read this first: http://en.wikipedia.org/wiki/Chroma_subsampling
Now, if you have 4:4:4 footage, you can push it very far. Film, HDCAM SR, Viper...all sorts of high end HD can have this sampling. However, a more common high end format is 4:2:2, like DVCPRO HD, HDCAM SR, D5. If you shot HDV...HD on those miniDV tapes, then your chroma sampling is 4:2:0. You are missing information COMPLETELY. So HDV cannot be pushed very far when color correcting. DV is 4:1:1, so it too cannot be pushed very far. If you shot on those formats, there is only so much you can do.

What's the best way to apply a detuned effect to a piano (audio or midi)?

Hi, what's the best way to apply a detuned effect to a piano (audio or midi)? I was trying to add the detune effect to a piano to make it sound warmer and old fashioned, any suggestion?
Thanks

Are you looking for a Honky Tonky Piano effect?
you need two istances of the same piano (exs24 Logic patch are great)
use fine detune (pitch) only one of the two piano istances.

What is the best soft wear update for a mac desktop with   System Version:     Mac OS X 10.5.8

What is the best soft wear update for a mac desktop with   System Version:
Mac OS X 10.5.8

It will depend on the actual model you have.
Upgrade Paths to Snow Leopard, Lion, Mountain Lion, or Mavericks
You can upgrade to Mountain Lion or Mavericks from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99 while Mavericks is free. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
Upgrading to Snow Leopard
You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard — Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s iCloud services; fees and
           terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service — this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
Upgrading to Mountain Lion or Mavericks
To upgrade to Mountain Lion or Mavericks you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion or Mavericks (Free) from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion — System Requirements
     OS X Mavericks- System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         1. iMac (Mid 2007 or newer) — Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) —
             Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) — Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) — Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) — Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) — Model Identifier 3,1 or later
         7. Xserve (Early 2009) — Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.

What is the best anti-virus software for my Mac?

What is the best anti-virus software for my IMAC?

If you are still using OS X 10.4.x "Tiger" please confirm.

Use what Apple already provided.
There will always be threats to your information security associated with using any Internet - connected communications tool:
You can mitigate those threats by following commonsense practices
Delegating that responsibility to software is an ineffective defense
Assuming that any product will protect you from those threats is a hazardous attitude that is likely to result in neglecting point #1 above.
OS X already includes everything it needs to protect itself from viruses and malware. Keep it that way with software updates from Apple.
A much better question is "how should I protect my Mac":
Never install any product that claims to "clean up", "speed up", "optimize", "boost" or "accelerate" your Mac; to "wash" it, "tune" it, or to make it "shiny". Those claims are absurd.Such products are very aggressively marketed. They are all scams.
Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources.
Illegally obtained software is almost certain to contain malware.
"Questionable sources" include but are not limited to spontaneously appearing web pages or popups, download hosting sites such as C net dot com, Softonic dot com, Soft pedia dot com, Download dot com, Mac Update dot com, or any other site whose revenue is primarily derived from junk product advertisements.
Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
Such "phishing" attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iTunes or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
Don’t install Java unless you are certain that you need it:
Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
Java can be disabled in System Preferences.
Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
Block browser popups: Safari menu > Preferences > Security > and check "Block popup windows":
Popup windows are useful and required for some websites, but popups have devolved to become a common means to deliver targeted advertising that you probably do not want.
Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
If you ever see a popup indicating it detected registry errors, that your Mac is infected with some ick, or that you won some prize, it is 100% fraudulent. Ignore it.
Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them:
The most serious threat to your data security is phishing. To date, most of these attempts have been pathetic and are easily recognized, but that is likely to change in the future as criminals become more clever.
OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.
If you elect to use "anti-virus" software, familiarize yourself with its limitations and potential to cause adverse effects, and apply the principle immediately preceding this one.
Most such utilities will only slow down and destabilize your Mac while they look for viruses that do not exist, conveying no benefit whatsoever - other than to make you "feel good" about security, when you should actually be exercising sound judgment, derived from accurate knowledge, based on verifiable facts.
Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.
Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind.

What are the best settings to use for the newest AirPort Extreme (AC wifi) with my optimum online service provider?

I have the current generation of the AirPort Extreme and a handful of devices that utilize the new 5Ghz A/C frequency. My internet speeds were blazing fast when I had first set it up but lately it has been lagging terribly. I was told that changing my dhcp did help, which it did it seems like it might be back to its normal speeds but I just want to know what are the best settings to configure for the airport so that I can get the most out of my service on all my devices? I'm using a CAT 6 cable which does help, I have a guest wifi setup with a wifi password which I understand will slow it down a little. Can anyone just point me in the right direction or just give me a step by step guide on what settings to configure? Should I really consider turning off the guest network?

I am assuming that you are looking to configure your network to provide the highest level of bandwidth possible for your network clients. If that is the case, the following are a few things to consider:
The Internet modem should support Gigabit Ethernet. That is the Ethernet connection between the modem and your 802.11ac AirPort Extreme should be Gigabit Ethernet.
Use CAT-5e or CAT-6 Ethernet cables between all wired connections.
Only expect 802.11ac performance with 802.11ac clients in the same room as the base station.
Eliminate or significantly reduce any forms of Wi-Fi interference on both the 2.4 & 5 GHz bands.
When streaming, especially HD video on your local network, use wired connections between the host and player devices when possible.
Other than the above suggestions there are no "magic" settings that you can make on your AirPort. Note: The Guest network shares the same bandwidth as the "main" network. Unless you have a network goal to provide this type of network, it is best left disabled.

What are the best dimensions to allow for iPad 3 Retina for full-page landscape images?

What are the best dimensions to allow for iPad 3 Retina for full-page landscape images?
I read an article and cannot find it that said something about trying to make it 2million pixels and JPG to keep it small, but what exactly should the dimensions be that I ultimately import? Is there some kind of a "density" setting I have to use, as well, when exporting from Photoshop, for example?

See Optimizing performance in your iBooks Author books
Density is discussed by Apple in this context as 'dpi'...

264 - new iPad

Good luck.

I have a 2007 macbook and I am wondering what is the best external hard drive for my Mac?

What is the best external hard drive for a 2007 Macbook?

The Apple USB superdrive would be a great choice for you, ( http://store.apple.com/ca/product/MD564ZM/A/apple-usb-superdrive?fnode=5f ) I am not certain but I am pretty sure that it has the same form factor as the MacMini (Not thickness but all the other dimenetions) so it fits just under and looks like an extension of your mac.

What is the best external hard drive for the MAC Book Pro with Retina?
I was looking at WD MY PASSPORT FOR MAC and Toshiba. I want something that will work best with time capsule! Suggestions on the best external hard drive would be greatly appreciated!!!

A Time Machine backup drive should be substantially larger than the system drive. If you have a 128 or 256 GB SSD then a 1 TB drive will suffice. If you have a 512 GB SSD then a 2 TB drive will suffice. As leroydouglas indicated any brand other than WD will do.
For 1 TB drives PlotinusVeritas gives some great suggestions here:

A 2 TB drive sold by Apple:
http://store.apple.com/us/product/H9378ZM/A/lacie-2tb-usb-30-porsche-design-p923 3-desktop-hard-drive
$130
A 2 TB drive just as good for only $92.

Hi, does your MacBook have Firewire, or just USB?
FW is far faster if you have that.
Avoid Bus powered ones.

What is the best virus/spyware software for OSX 10.6.8?

What is the best virus/spyware software for OSX 10.6.8 on an iMac?

Csound1's answer albeit short is correct. Because there are no viruses (as in zero, none, nada, zip) for OS X having antivirus software is a waste of time, resources and possibly money. About the only need for antivirus software is if you frequently download files you know nothing about and then forward them to Windows users. In that case even though you still don't need anything for OS X you are protecting the Windows users from your passing along infected files. Most anti-virus software for OS X tend to create more problems than they solve however if you insist I'd recommend ClamXav which is free, non-intrusive and is frequently updated.

What is the best word processing program for mac?

What is the best word processing program for Mac?

That's an impossible question to answer - what type of writing will you be doing?
Before we can point you in a direction you need to tell us what kind of writing you will be doing. As phrased, the question is a bit like "what's the best car?" Well few would doubt that a Ferrari is superior to a Honda minivan, but the Ferrari will not much use if you're dragging 4 kids, two dogs and the grandparents along.
Academic?
Word is the nearest thing to a standard format in the Humanties, but in the sciences and math you'll find Tex more useful for laying out formulas. The older Pages is quite good as a substitute for Word in many cases in the Humanties, but you'll have big problems with citations in the newer version. Apps like Nisus Writer Pro and Mellel are more powerful than Pages, but each have shortcomings. Scrivener and Ulysses are excellent drafting tools but you'll need a Word Processor for final layout. There are lots and lots of lightweight editors out there - Byword, iaWriter (and Writer Pro), OmmWriter - that have little functional use in Academic settings - poor or no support for citations for instance, or poor or no interoperability with Word - but which might be excellent for other uses.
So, back to the key question: what kind of writing will you be doing?

What is the best word processing program for ipad2?

What is the best word processing program for ipad2?

I would recommend using Pages for what you are doing. It is the best one to use on the iPad itself, and has the ability to convert to an MS Word format. I know that it can do this through email, but I am also fairly certain you can import it in this format through iTunes, though you may need to convert it on the iPad itself.
With iOS 5 and iCloud, I recommend kicking Word to the curb altogether and going with Pages on both machines. Not only will everything be more seamless, but iCloud will update the changes you make, on either device, automatically. And Pages is only 20 bucks through the App store for the Mac (OS 10.6.7 or later needed).
