Image capturing black screen

I connected a usb to labview using the IMAQdx. At first, it would run but would produce timeout errors after 5 pictures. Now, I manage to get the cycle to run 50 times but the image only comes out as a black screen. What could be the cause of this and how can I fix this?
Solved!

Thank you for your reply. Attached are two attempts that both produce the timeout error

Problème Image Noir / Black Screen

Bonsoir, j'essaye la version d'essai de photoshop CC, j'ai plus l'utiliser deux, trois fois, mais là, quand j'ouvre une image, celle-ci devient noir alors que la miniature affiche bien la photo normale. J'ai déjà essayé d'aller dans Edition / Préférences / et de désactiver " open GL " et de remettre en normal mais cela n'a rien changé, c'est toujours pareil. Je suis sur un ordinateur portable MSI, avec une AMD Radeon HD 7970M. J'aimerais bien résoudre ce problème au plus vite afin de tester cette version d'essai pour peut être l'acheter plus tard, mais bon, pour le moment c'est plutôt mal parti ...
Donc, toute aide est bonne à prendre.
Cordialement, salutations.

Audio but NO images show - black screen -up in the canvas viewer window????

Hi all,
I'm a newbie having problems with a file in FCP where the audio plays and but no image shows up in the Canvas window. I imported the audio from my camera and had some kind of a problem in the browser window where the sequence didn't show up with the actual length of time...it read 00:00:00. I reimported the quicktime file into FCP Express, and then it showed up fine. When I reopened it in FC Pro, this time, the sequence shows the full amount of time of the file, but I'm still getting all black in the canvas window. I'm at a loss to explain this. I have a feeling I did something wrong during the initial import, and so the actual source file is somehow corrupted. But when I open the source file in quicktime, it plays fine. It's only within FCP that it's all dark.
Help!!!!!
Thanks in advance

sounds like you do not have a source file that FCP recognizes.
What camera and what codec does it shoot? did you convert to a prores or standard QT format before or after ingesting?

Help! Image Capture scanning detected images solid black! Screen cap inside.

I know this is not a forum for Image Capture, but there is no dedicated forum for it, and I figure there are smarter people here with regards to images.
Image Capture is scanning ~some~ detected images solid black. It presents an overview scan just fine, but than the final files are black.
Here is a screen capture:

iPhoto earlier than iPhoto 9 (11) does not support Grayscale because it adds a color profile name Dot Gain 20%. This profile is not compatible with iPhoto. You can either rescan those photos as color photos or change the profile to sRGB or RGB.
I've created an Automator workflow application, Convert to JPG and Embed sRGB profile, that will convert B/W files to a jpg file with the sRGB profile. However, is doing so it adds an additional jpeg compression level to the file resulting is a smaller file size but not a smaller image size. You can download it from Toad's Cellar.
The conversion will have to be done on the photos outside of iPhoto before they are imported. So you will have to export the original files to a folder on the Desktop, run the application on them and then reimport the new files.

Windows Server 2012r2 WDS capture image hangs at black screen

Hello,
Where did you get the original image? If you download it from MSDN or technet, can you provide the link?
And is update 1 integrated with the original image or you install it manually after installation?
In order to address the issue, we need collect some more informaiton.
Thank you.

Using Firefox to access facebook chat Button or online friiend chat button generates a Black screen with CANNOT LOAD IMAGES and no chat window opens.

This does not happen in other browsers and it happens on a variety of computers I have access to and would seem to be a common problem but I can find no identical cases in my searches of
Firefox , Facebook or windows help or Google search. My home machine is only a P2 with WINXPCORP but works fine and I have done all updates but still have this continuing problem every time I try to use Firefox
to access Facebook chat but it does not happen with IE or chrome
The response to clicking on chat button or friend chat is a black screen with small center square box with blue title bar that says
'' VIEW IMAGE FULL SCREEN - (42) FACEBOOK X""
center of box is ""! "" mark in yellow triangle and wording
"" CANNOT LOAD IMAGES ''' OK
clicking on OK returns to facebook page but no chat opens.
Some times |VERY RARLEY if as the page loades you click on
chat button with 1/2 second of it appearing chat will open.

Hi,
Please also see [https://support.mozilla.org/en-US/kb/Problems%20using%20Facebook%20in%20Firefox this.]

I cannot view images in iphoto - only black screen

I had problems being unable to boot my iMac this week and ended up having to take it to the Apple store where they re-installed the operating system and all seemed fine. Now however, although I can view thumbnails in iPhoto, when I click on them I just get a black screen.
I've checked the images do still exist in the file folders and I had a slideshow running as a screensaver - this still shows the images but I cannot access them through iPhoto.
Can anyone help?
Thank you

There are several possible causes for the Black Screen issue
1. Permissions in the Library: Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Include the option to check and repair permissions.
2. Minor Database corruption: Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild.
3. A Damaged Photo: Select one of the affected photos in the iPhoto Window and right click on it. From the resulting menu select 'Show File (or 'Show Original File' if that's available). (On iPhoto 11 this option is under the File -> Reveal in Finder.) Will the file open in Preview? If not then the file is damaged. Time to restore from your back up.
4. A corrupted iPhoto Cache: Trash the com.apple.iPhoto folder from HD/Users/Your Name/Library/ Caches...
5. A corrupted preference file: Trash the com.apple.iPhoto.plist file from the HD/Users/ Your Name / library / preferences folder. (Remember you'll need to reset your User options afterwards. These include minor settings like the window colour and so on. Note: If you've moved your library you'll need to point iPhoto at it again.)
If none of these help:
As a Test:
Hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Create Library'
Import a few pics into this new, blank library. Is the Problem repeated there?

OS X LION Issues with Full-Screen; iPhoto, Image Capture & Mail

Hello,
I'm experiencing un-Apple-like issues (bugs) with Lion in Full-Screen mode.
For example - iPhoto doesn't seem to like Full-Screen mode. If iPhoto is open and I connect a camera, for which I prefer Image Capture to retrieve my pics... Image Capture opens 'behind' the full-screen iPhoto, but I can't get to it. Image Capture shows as open on the menu bar in iPhoto's full-screen mode. If I go to the desktop (where it should be opening) Image Capture isn't 'on top' and clicking it takes me back to iPhoto full-screen
Similarly, if I get mail and return to the desktop (the only way to see the dock) and I click on the 'Mail' app icon - I am catapulted into Image Capture... or iPhoto. Returning to the Desktop to click the Mail icon from the dock... takes me to Image Capture... or iPhoto. The 3rd try takes me to the Mail.app which is usually always open and in full-screen mode.
While I'm complaining about bugs, I'd like to mention that I am fully dismayed by the loss of control in full-screen mode when using apps such as Mail or iPhoto. The Mail app opens an email to edit (such as a reply) but you can't access any other mail docs to 'cut and paste' info from. I can only click SEND or CANCEL.
What if I don't want to CANCEL? I just want to go to another email and cut a piece to paste.. I have to exit full-screen mode which allows me to open two email documents at once, then cut and paste. Essentially Mail in Full-Screen is only a reader... not a work area. I can only access the document I have open, since it greys out the Message Viewer. You can't click on the message viewer nor access any of the features of Mail.app. You can only write your email and either Cancel or Send. Where is the 'hold on a second while I go cut and paste'? I don't want to cancel.
Can't seem to use Safari since I'm constantly three-finger swiping it away. My cursor hovers over a text field and suddenly it's zooming in and locks text input. I have to iPhone-like swipe to expand to exit this inadvertent partial (very slight) zoom. Sometimes the zoom is so partial that I can't figure out what's going on until I just exit full-screen mode, close the window and start over.
Seems like I'm starting over and over and over... just to do simple things. Inadvertent zooming, inadvertent 3-finger returning to Desktop, inadvertent changing apps... ugh.
I'm willing to let go of the old and embrace the new future but so far it's been pretty uncomfortable for me to constantly monitor my overly sensitive trackpad gesturing combined with constant bugs and glitches. I'll save complaining about iPhoto's over-simplification (apparently for dummies) like the new Edit menu, Export menu, etc.. since it's more iLife than Lion related. Rate Lion: 2 out of 5 stars for ease of use & features complicated by unrefined software issues.

I've tried follwoing these instructions but I have an issue with
# Create snort user. The intention is to let user snort have access only to the snort database.
$ sudo createuser -U _postgres -P snort
Password:
Enter password for new role:
Enter it again:
Shall the new role be a superuser? (y/n) n
Shall the new role be allowed to create databases? (y/n) n

It keeps telling me "could not connect to database postgres: could not connect to server: No such file or directory"
I'm running OSX Mountain Lion, and have verified using serveradmin status postgres that it is up and running.

No image when embedding a video/movie into my PDF file,just a black screen?

I cannot embed videos with an image on my computer into my Acrobat Pro 8 file. I get only a black screen, which I must click on to play the video. How do I import the visual image along with an arrow for playing or a navigation bar at the bottom for play/pause?

If you're creating video content in Acrobat 8 then it's "legacy media", which has a different structure to the Rich Media Annotations created by Acrobat 9 and later. RMAs use Flash Player and there are inbuilt choices for the play control buttons when you create a new annotation, but legacy media hands over control of the video rendering to whatever external application it can find installed on your computer, so what you see will vary.
The poster frame for a video can be controlled when the annotation is created - either sampled from the video or selected manually from an image file.

I want image instead of black screen when video ends.

Hi guys,
I am wondering how you place an image at the end of a VC video. I tried placing several images at the end of a recording but it always ends with a black screen when it is produced. Here is the video I am working on and I want the last text you see to stay on screen instead of the black screen.
Thanks Gary Garnett

Hi,
I would try a Safe Boot first. (This will take longer than a normal Boot and you will need to Restart afterwards).
If it were an older OS I would also suggest going to System Preferences > Displays and making sure the display is set to Millions. (My MacBook Pro does not have this option in Snow Leopard so I did presume Snow Leopard does not have it).
With some laptops there have been some issues with the cable up the back of the screen pulling loose with regular and frequent use of the lid, but this will not apply to you based on your specs. (it does take time to appear and is also somewhat rare). However it seems enough contact with the camera can make it appear in System Profiler and power it on but not give a pic.
If a Safe Boot does not work I would also try a PRAM reset.
Shut down the computer.
Restart it holding down Apple/CMD (or ⌘)+ALT( ⌥)+P+R Keys until you have heard three Start Up Bongs.
This is actually "less" destructive in that it clears less memory items than Safe Boot but they are different enough to warrant trying.
Do you have an older version of iGlasses installed ?
The one for Leopard does not work for Snow Leopard.
Do you have Web Browser open ?
This may point to Google Video Chat Plug-in and Flash Conflict. It would be rare to allow another app to access the camera even if not displayiong a Pic.
(Chrome Installs the Plug-in as does the standalone download).
Knowing what "any application" exactly you are trying might help us pin it down.
Any additional downloaded apps that can use the camera ?
Do you happen to have something balck in front of the camera ?

Capture is just black screen

just got fce 4. using sony camcorder to capture. capture area says VTR OK, and controls allow play, stop shuttle---thats working fine, but when i CAPTURE NOW, i just get a black screen. saw other posts that suggested setting view>video to canvas. did that. still black screen. what am i missing?

Do you mean that whilst you are supposedly capturing, the capture screen is black ?
Also you give no details about your computer, camera, how FCE is configured (Easy Setups etc.) and exactly what you are doing.
A black screen is not common and without more details it is unlikely anyone will be able to work out where you are going wrong.
Have you forgotten to rewind the tape and are capturing from the empty tape past the last shot ?

I want images instead of black screen on VC video.

Hi,
I made a video with VC but I want an image instead of a black screen when it is producd. I tried ending my production with various images but when it is produced there is always a black screen. Any help would be appreciated. Here is my video I am working on- http://www.computertuneupvideos.com

When I select an image, why do I see a grey warning triangle and black screen?

When I select an image, why do I see a grey warning triangle on a black screen? I can see the image in the Event review, but it won't let me see it independently.

The ! turns up when iPhoto loses the connection between the thumbnail in the iPhoto Window and the file it represents.
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. (In Library Manager it's the FIle -> Rebuild command)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

FCP 10.1 DV capturing from camera breaking the scenes into unwanted clips by flashing a black screen on import window. But its fine and accurate with adobe premiere pro cc ? Any solution * Advance Thanks

FCP 10.1 DV capturing from camera breaking the scenes into unwanted clips by flashing a black screen on import window. But its fine and accurate with adobe premiere pro cc ?
Any solution * Advance Thanks

FCP X will import into separate clips every time it detects a scene change (as when you stopped and started recording in the camera). There is no option to avoid this, as far as I known.
You may try importing from camera using Quicktime Player X and then bringing the imported file into FCP X.
