  • Why does the video appear darker it is?

    Hello

    I used FCPX for a few years but I started on FCP and must go back occasionally.

    I don't know how or why, but the images in the viewer and canvas appears darker than it really is. But when I export without problem, everything's fine.

    Any ideas? At something I touched on by mistake?

    What's also weird is, there is no record for the FCP or FCS in the Applications folder. There should not be? In one case, shouldn't be Qmaster or something or other? I just installed FCP of FCS on my new MBP 8 months past, but maybe I trashed a few things by mistake. Should I color or any other application?

  • Why does my signature appear clearer than normal text?

    I typed in my signature, as noted, but it does not appear as the "body text" or the same as the body of my emails that I type. He appears as a footer and is lighter than normal text.

    Thunderbird shows after the separator of signature (dashboard dashboard entered space) in gray. Maybe others don't have the right signature delimiter? Note that the signature is not physically changed in gray text in the outgoing email, it is just a matter of how Thunderbird displays it.

  • Why does my image appear black?

    I just loaded CS4, open a previous file in Photoshop, the image appears in black, it looks fine in the browser, and when I drag the screen he appears, as soon as I let go he turns on the black for again. The file seems fine in Bridge. I have Windows Vista and updated for CS3 where the image seems in good condition when opened in Photoshop.

    ... also make sure that you have updated PS version 11.0.1 and, if the problem persists, turn off OpenGL in Preferences > Performance.

  • Why my picture will appear on the screen when I click the print module in Lightroom?

    I have had no problem printing in Lightroom until this weekend.  Now when I select an image in the library module, then click the print module at the top right, I get the general page for the print module with right and left selection committees - but no picture.  Just an empty space with the grid lines, etc.

    A possible problem, is that I figured out how to contact sheets last Friday (which worked fine).  My problem started next time I open Lightroom, then maybe I clicked on something wrong by mistake when I was doing the contact sheet.  I've been through to get to its previous state, but something still does not work.

    Suggestions welcome!

    Thank you

    Kathryn

    For the record, I understand the problem.  When I created a Board-contact, I used "select flagged photos" to indicate the pictures you want to include.  When I went to print single images, I forgot to turn off this feature and return to "selected picture" for printing.  Where the problem.  Now, it seems to work very well!

  • Why does my magazine appear melted in kiosk

    Hello

    I updated the tools DPS for the last. I used v28 to create 2 apps for the newsstand magazines.  This is not my first time. I followed all the steps, but to my surprise when I downloaded a copy of developer to test on my ipad. the attached screenshot is what I got. My magazines seem to fade. When I type on them, none of them open.

    Please note that I have ios7 running and the version is iOS 7.0.4 I use MAC OS X 10.8.4, my apps are all up to date. My iOS is expiring on certificate of membership, but I will renew it shortly.

    What could cause this behavior of my magazine app appear bland in kiosks.

    Please, I beg you, I await your response, newsstand.jpg

    This happens when your .mobileprovision file is not UDID of your device in it. Go to the iTunes and re Developer Portal - generate your mobileprovision file and make sure to explicitly check the box next to the UDID of your device. Then rebuild the application with that file.

  • Why does a number appears in parentheses next to the number of font size in the character Panel? as 9pt (8.84)

    I m working on a book, and when I select a title, in the font option in the character panel size appears a number in parentheses next to the number that indicates the size of the font. For example, I chose 9 pt for the title, but after I applied this seting, in font size option appears: 9pt (8.84) so the size of the cuff is 8.84 and I couldn t change that!   I compare this title with other people, whose size is 9 and is a little smaller.

    I applied a paragraph Style to the headline, located in 9 pt font size, and the same appears: 9 pt (8.84) the problem is that I have a lot of headlines this ditch the book and I would like to change their size in the paragraph style and it doesn´t work, always appear a smaller number in parentheses.

    I know not if I chose Auto in the option of the attack, a number in brackets appears to indicate the proportional main of the text, but it in font size option. What is going on? Can how I change this?  HEEELP please! (Sorry if I have some errors, I usually speak Spanish ) Thank you!

    Luis

    Are you sure the version number? Version 3 is CS and CS3 is version 5. I do not see the parentheses in CS3, but it doesn't really matter. Select the image, and then in the context menu of Palette control seek an order as "Reset scaling to 100%" which should correct the figures to represent exactly the size of the type currently is. Then fix the setting that Bob stated in your preferences.

  • Black box appears on the screen, don't know why.

    Don't know what I did, but this just black bar appears on my screen of firefox and I can't seem to go in. Make a right click on it does not work. I tried to restart my computer and restart firefox, but that did nothing.

    Hello

    Try Firefox Safe mode to see if the problem goes away. Safe mode is a troubleshooting mode, which disables most of the modules.

    (If you use it, switch to the default theme).

    • You can open Firefox 4.0 + in Safe Mode holding the key SHIFT key when you open the desktop Firefox or shortcut in the start menu.
    • Or open the Help menu and click on the restart with the disabled... modules menu item while Firefox is running.

    Once you get the pop-up, simply select "" boot mode safe. "

    If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to understand that one. To do this, please follow article Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems .

    To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

    When find you what is causing your problems, please let us know. It might help others who have the same problem.

    Thank you.
