Colour shift - how to fix?

I'm working with an old video clip which features bold yellow text. However, the chroma has shifted slightly to the left giving it a blurred look, with the yellow appearing slightly outside of the text itself. Is there a way to fix this?

This is Y/C delay. High end vtrs used to have a knob to correct this (which got worse with generations) Assuming that's not possible google for AJW's Y/C Delay" filter and try that.
Or you could try Channel Offset in the effects tab of FCP Having captured media with the error, this allows you to move channels around relative to each other. To correct for Y/C delay on yellow text you will need to add two instances of the Channel Offset to shift red and green channels (equals yellow in additive colour space)
Good luck.

Firefox crash when change language with ctrl + shift how to fix it

I know that there is key combinations in firefox starting with ctrl + shift. I wonder how to disable this combinations instead of language change

It would be better to disable the Ctrl+Shift combination to rotate the installed languages and instead assign the specific key sequence (Alt/Ctrl+Shift+number) to select each keyboard layout to avoid such issues.

Why have all my Lightroom and Photoshop files just developped an awful colour shift? how do I correc

Why have all my Lightroom and Photogshop files suddenly developped an awful colour shift when they did not have this a week ago? I can open them in other applications and they view correctly. How can I correct this in Lightroom? HELP urgent!!

Antonia,
Probably your monitor profile is corrupt.
If you're on Windows, see here:
http://www.lightroomforums.net/showthread.php?14070-How-to-assign-an-sRGB-ICC-Profile-to-y our-monitor-%28Windows%29
If you're on a Mac, you'll need to try something similar to set your monitor profile to sRGB. NOTE: this is merely a temporary fix. You need to acquire a hardware calibrator (decent ones can be had for around $100) and calibrate your monitor with it.

Strange colour spots (red & green) appear after RAW files converted to JPEG, anyone know how to fix it?

Strange colour spots (red&green) appear after RAW files converted to JPEG, anyone know how to fix it? Thanks.

I use "Export" function to convert the picture from RAW format to JPEG format, resolution 240 pixels per inch. Strange red dots appeared in the area supposed to be dark grey, as per the picture below. The red colour does not appeared in the original RAW picture when viewing from Lightroom, only exist in the JPEG it created. Any ideas how to fix this? Thanks!

Weird colour shift on TV through HDMI

Hi,
I'm using my TV with XBMC to watch videos on my computer more comfortably, but even since I changed my computer the image get those weird shifts where it goes black for about a second, comes back on looking weird, then about 20 seconds later it's one second of black and then back on as normal again. But if I change channel on my TV when it happens, and then switch back to the HDMI channel corresponding to my computer, the image is fixed. I've tried timing this issue, and it seems to appear roughly every 20 minutes, but it can appear twice in 5 minutes, or not at all in 40...
Because an image is worth a hundred words, I took a picture with my phone during one of these colour shifts, here's what it looks like: http://img152.imageshack.us/img152/3284/imag0063gc.jpg . As you can see by the xbmc menu looking weird too, this is not the video's fault.
I've also tried switching the cable, but the issue remains. I've been using this setup for a while, but as I said, I changed computer recently, and part of this change was going from a nVidia card to an ATI one, more specifically a radeon HD 7870, and I'm using the official AMD driver (which is kind of required, since the free driver apparently doesn't support sound over HDMI for my card yet).
It's probably worth mentioning that my primary display, which is plugged in VGA, does not have this issue. Also, I have a Windows dual-boot, but I have yet to test if this issue also appears on Windows (which is kind of a pain to do, due to the randomness of my issue...).
I've tried googling this for days and have yet to find anyone reporting the same issue, but seeing how English isn't my native language, I might not have used the right keywords...
Because I guess this is relevant, here is my xorg.conf on pastebin: http://pastebin.com/2eWPKnt2 . This was generated using amdcccle, so it should be legit (though I do miss nvidia-settings, amd got some work to do on their GUI tool). Not sure if this is relevant, but just in case : to launch the computer on my TV, I use this xorg.conf (named xorg.conf.TV in my system), and start X with the following command (through an alias, of course):
xinit .xinitrcTV -- /usr/bin/X :1 -config xorg.conf.TV
And my .xinitrcTV containing the following:
setxkbmap fr
xbmc
xterm
So here I am, and I don't really have any idea what I could do to fix this problem... Any help would be greatly appreciated.

Colour shift when placing PSD files into illustrator

Hi there
I have tested this issue on CS 3,4 and 5.
bascially if I create a CMYK document with a colour image and save this down as a psd file with the coated Fogra 39 embedded in it. If I create a new file within Illustrator with the same colur management and place the psd file into the document and check the link option (so it is a linked file), the colour shifts when using the colour picker. If I print the document from each APP they visually look different as well.
If I place the psd into illustrator without selecting the link option the colour has the same CMYK values as the psd within Photoshop and also prints correctly.
i can only assume that there is an option somewhere in regards to the "link" option and how this changes tha colour values somewhere? If not is there anyway I can get around this issue so I can use linked files without the CMYK values changing?
Thanks in advance
Paul

Hi guys
Thanks for the responses.
I use bridge to blanket the colour settings so this i feel this is not the issue here. If you have a moment and would kindly create a colour tint within PS of what ever colour, save this down as any format and place this into illustrator with the link checkbox checked you will see the colour data has physically changed for the CMYK values. This results in the prints looking different as well. If you deselct the link check box when placing the file the CMYK values are the same.
I tried the overprint preview option. This changes the viewable colour on screen but not the CMYK data of the file.
There seems to be a fundamental floor with this link option for some reason.
I might have phone Adobe direct for this iisue as I cannot find a fix for this.
Many thanks
Paul

Colour shift in save for web when saving on PC and then viewing on Mac

Hey peeps, I am aware of this colour shift when saving images for web. I have a designer resizing, cropping photos, and then saving on PC. He uses PC and when he sends the photos over to me on my Mac there is a big colour shift (photos are much lighte
Could anyone please explain exactly what he needs to do in order for these photos to look the same as the originals on my computer, basically no lightness shift? Any help would be much appreciated.
Thanks
Adam

Because the WWW is based on untagged (2.2 gamma) sRGB - your genius is probably sending you untagged sRGB if they were Saved for the Web (that's how I prepare my Web color).
Your Mac display should be profiled to 2.2 gamma (you are likely at the old default 1.8 gamma now if you're seeing a lightness shift on untagged sRGB)...if you want "your color" back in Photoshop, you will need to (re)Assign the sRGB profile...

Whenever I try to use my macbook, it will work for about 10 min. then the screen will go black, the computer will not respond to my commands, and I have to restart it. Can anyone tell me what's going on, and how to fix it? Thank you!!!

Hello everyone, like most people on this site, I am having difficulties understanding and fixing my Macbook Pro. About a month ago my computer screen went black, the computer was unresponsive, and it started making a beeping noise. I restarted the computer, and it seemed to have fixed itself. 6 days ago, I put my laptop into it's case with some papers, went home (about 30 min. after putting laptop into case), and opened my bag. My computer's fans were on, the computer was really hot, and when I opened the computer, the screen was black and unresponsive. I turned it off, let it cool down, turned it back on, started to stream a video on Hulu, and about ten minutes after, the screen went black again and the computer was unresponsive. Now everytime I turn it on after about ten to fifteen minutes the screen will go black, the computer will become unresponsive, and I have to shut it off. The weird thing though is that everytime I restart my computer, when I reopen my account, my computer acts as if nothing has happened, and everything I had opened or unsaved is still there without autosave saving the documents.The screen also goes black and the computer becomes unresposive when I move the computer around. I get a lot of pop-up ads and other crap on my computer when I am on the internet. I don't know if one of those pop-up websites might have given me a virus or may be the cause of this problem. I don't now what is wrong with my computer or how to fix it, but if anyone has any advice, I WOULD GREATLY APPRECIATE IT!!!!!!! Thank you very much!!!
-- Sincerely, A very confused, scared, and hopless Macbok Owner

To get rid of "pop-up ads and other crap on my computer when I am on the internet", click on Safari in the Menu bar, and select Preferences. Next select Extensions. Delete all of them. Restart Safari.
The first step in addressing the black screen is an SMC reset.
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

I am having major issues with links in keynote! Even though the links (a navigation system) are on the master page, they are only working on some of my slides. Anyone have ideas on how to fix this or similar issues? Help!

I am having major issues with links in keynote! Even though the links (a navigation system) are on the master page, they are only working on some of my slides. Anyone have ideas on how to fix this or similar issues? Help!
I have created a navigation system on the master pages and set the presentation to links only mode. I also have other links scattered throughout the program, like a linkable table of contents, etc. Some of them work, some of them don't. Not sure why. Anyone out there having similar issues? Or have any idea on how I can solve this issue? Any help would be appreciated!
Thanks!

Links should not create any problems in Keynote. If they are set up correctly on text, the text will be underlined. Objects that have links will have a curved arrow bottom right, if you click the arrow a popup will display the link information.
Try this repair for Keynote, ensure you complete all the tasks and in the order shown:
1
delete all the iWork applications if you have them, not just Keynote, using Appcleaner from Mac Update, its a freeware application
2
empty the trash: Finder > Empty Trash
3
Shut down your Mac, wait 30 seconds, then power on the Mac, immediately after the start chime, hold down the Shift key
When you see the grey Apple symbol and progress indicator (a spinning gear), release the Shift key.
If you are prompted to log in, type your password, then hold down the Shift key again as you click Log in.
4
Let the Mac fully boot up, it will take longer as the OS is repairing the drive
5
when fully booted, go to Applications > Utilities > Disc Utility; click on the boot drive then First Aid tab and click repair disc permissions
6
when complete, restart the Mac normally, Apple menu > Restart
7
install Keynote from the Mac App Store
let us know if this helped

Viewing angle (with no colour shift) on new iPad much narrower than older iPads

I just got a new iPad yesterday and the new display's resolution is magical!! I am unfortunately experiencing the yellow tinted screen that others are, but I'm hopeful this will improve over a short time as any glues involved perhaps dry. I THINK perhaps it's already improved though this could be my imagination, hard to tell. It's also clear on a totally black screen that it fails to go as dark as my iPad 2, which itself failed to go as dark as my iPad 1. Still, that resolution, spectacular...
I am however also experiencing a very narrow viewing angle, especially in the vertical direction, it's the most worse when held in normal portrait orientation with the cameras at the top, if I tilt the top of the iPad away from me then the entire screen colour shifts to yellow quite strongly within about 10 degrees or so. I'll shoot some video of it at some point compared to the iPad 2. I wonder if the colour yellow could be linked to the general yellow tint that can be seen on whites even in perfectly straight viewing. But I also wonder if the new retina display just has a much narrower viewing angle without colour shift compared to the older iPads.
Would love to hear how other people's new iPad screens are performing in this regard. Are they all shifting as they're tilting, especially in that vertical tilt I described?
Cheers

I have the same problem. Here is the pic I took to compare with my old iPad 2.

my mac keeps freezing when i try and print anything from preview. any ideas as to what the issue is or how to fix it?

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up a guest account” (without the quotes) in the search box.
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem(s)?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
Note: If you’ve activated “Find My Mac” or FileVault in Mac OS X 10.7 or later, then you can’t enable the Guest account. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.
Test while in safe mode. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

Unfortunately if there are various colours across the screen then you have broken the LCD Screen and it will need replacing. If the colours change when you press the area lightly then this is another symptom that you've broken the screen.

When spanning new tabs (firefox) my users are asked to re-authenticate with pages already signed into. Can you tell me how to fix this issue for firefox users?

With some research I found regedit setting called “TabProcGrowth” that allows tabs to span without re-authenticating with certain browsers. Can you tell me how to fix this issue for my Mozilla Firefox users? Our current version of Mozilla Firefox is: 24.5.0 (x86 en-US). This was first noticed with a product called Confluence that we use in our Tech Support area. Users are having to reenter their password every time they click on a new link in confluence. Any help would be appreciated.
Thank you,

Hi Bernie:
As long as you are accessing your internal server on http:// or https:// then I would expect the normal rules to apply. To see whether some external requests are being blocked, you might try using Firefox's Web Console, Network tab.
You can open the console in the lower part of a tab using either:
* Ctrl+Shift+k
* "3-bar" menu button > Developer > Web Console
* (menu bar) Tools menu > Web Developer > Web Console
Click "Network" on the top bar of the Web Console.
Then use the address bar or a bookmark to launch Confluence in the same tab. Each request made by Firefox should be displayed along with the result. You can click a row for more details.
When I look up "TabProcGrowth" it seems related to the Protected Mode feature of IE8 and newer, which is not (yet) applicable to Firefox. http://blogs.msdn.com/b/askie/archive/2009/03/09/opening-a-new-tab-may-launch-a-new-process-with-internet-explorer-8-0.aspx
However, if Confluence is heavily reliant on plugins such as Flash or Java, that could be a factor because plugins are run out-of-process in Firefox. In that case I suggest checking with Confluence for suggestions.
