Strange thumbnail/preview generation

Today Bridge ( cs4 ) decided on his own to recreate the thumbnail and preview cache . Now some pictures have
blown highlights and look horrible - nothing to do with the previews I had before this improvised cache renewal .
I tried to purge it again but it still creates the same washed previews . If I open a file in preview , quicklook or photoshop everything is ok , it's only
the bridge thumbnail/preview that looks wrong . PSD files aren't concerned by the problem , only .jpgs

Hi Ann,
Thanks for your reply. Do you know if there is somewhere this can be logged as a feature request?
It does seem styrange as other NLE's I have used in the past, always retain thumbnail previews between the restarts of the NLE application.

Thumbnail preview generation

Maybe it's just me but everytime after starting up Premiere Pro and looking at my h264 clips in the project Premiere Pro always takes time to generate the thumbnail previews. I don't mean in the timeline but in the windows of where clips viewed in the project. Once they are visable/generated you can close and open the window and they appear instantly.
However if I close Premiere Pro down and restart and open the same project and then open up the already imported files in the project and view as thumbnails it then goes and takes time again to generte them all over again.
Maybe I've missed an option some where to store or cache these previews, would love to, atleast to save a little time.
Any input would be great.

Thumbnail/ Preview Question

I have used Aperture since the start.... but i am getting a strange behaviour with thumbnails/previews.... imported raw files from a Canon 1DS MK2 in to a new project. Activity monitor shows the processing of the files (1,146) i am then getting previews that look faded.... until i turn off 'Quick Preview' and it will load the properly saturated preview. I have rebuilt the thumbnails and reprocessed a few times..... and when this has finished there are still a mixture of good previews and faded previews. Makes it very hard to edit properly.
I am using a referenced project with the images stored on an external FW800 drive.
Any ideas ?
Thanks.

Maybe it isn't the smartest way, but this should work: ... call info.Parse (host, stream) etc here - the usual stuff { // find biggest jpeg image for preview unsigned int subMaxW=0; int subMaxI=-1; for(unsigned int i=0;i<info.fIFDCount;i++) { dng_ifd* pIFD=info.fIFD[i].Get(); if (ccJPEG==pIFD->fCompression && 1==pIFD->fNewSubFileType) { if (pIFD->fImageWidth>subMaxW) { subMaxW=pIFD->fImageWidth; subMaxI=i; } } } if (subMaxI>=0) // load desired jpeg preview { unsigned int i=subMaxI; dng_ifd* pIFD=info.fIFD[i].Get(); if (ccJPEG==pIFD->fCompression && 1==pIFD->fNewSubFileType) { // seek to pIFD->fTileOffset[0] and load jpeg } } }

Where are my thumbnail previews?

After upgrading my hard-drive (time machine restore) most of my thumbnail previews in Aperature 3 are gone. Most but not all. Also, many without the preview will render only in large format - but no thumbnail sticks after backing back out. The photo's are there but no previews are shown. I've tried "updating preview" to no avail. Aperature CPU usage ramps up for a minute or two then fades away without completing the preview generation. Any suggestions?

FYI. It says my HD is offline so it can't update from the Master. But the weird thing is only some of the files are effected by this. Tell me I don't have to repoint Aperature to each file again. I guess I could reimport the projects...
Since your Library and your file structure should be unchanged by the drive replacement, it should be simple work to reconnect any and all images with missing Masters to their Masters.
The next thing to test is your Aperture installation.
Create a new Library, populate it with a few dozen images. Does it work as expected?
Can you open your Library on another computer (one with, of course, Aperture installed)?
Do you have any other back-ups of your Library? Something seems to have gone badly wrong over the course of your drive replacement.

Layer Thumbnail Preview Problems CS4

I recently started having an issue with the layer thumbnails. In the past, when I would create a new shape (with the rectangle tool for instance) the layer thumbnail preview would look like the first image I've inserted. Now when I create a new shape with the same tool (in a new file) I get a layer thumbnail preview like the second image. All the panel options are the same, so it isn't the thumbnail size setting under panel options. I prefer the thumbnail preview from image 1. I am creating documents that many people will be using (most have basic photoshop skills) so the preview from image 1 is much easier to use and understand. Any help with this situation would be much appreciated, as I cannot figure out what back end setting has changed?

Thanks! They are exactly the same in every way. I think I've figured it out. It seems the layer preview is based on the size of the file or document. For instance, the problem started when I created a business card file sized at 3.75" wide by 2.25" high. Don't know what the magic number is, but when I created a file sized at 5" by 5" square, the layer thumbnail preview looks the way I want it to (image 1). It's strange, but it looks like I'm going to have to live with it when creating file sizes like this...

Lightroom thumbnail previews

Just imported a folder with 32 DNGs, and the generation of thumbnail previews stalled after creating three images; would appreciate help on getting the remainder of the folder's images to appear. Thanks!

Re: Lightroom 3.3 Corrupt Thumbnail Previews
LR 3.3 and PS 4 ext. The original was a camera phone jpeg.
No, I have only VERY rarely had this happen. I don't use this workflow. I was trouble shooting an issue for someone that is having a problem. I was quite surprised to see it happen. The computer is an i7 running Vista 64.
Your fix would require ALL previews to be rebuilt. I have a catalog of over 80,000 images. I don't see that as a reasonable fix. If it was a problem, I'd rather try deleting image from catalog and then sync the folder again and see if that fixed it. No need to trash a bunch of good previews for one bad apple. : ) especially since it's just a test jpeg image. I suspect a read/write time with image size and such playing a role.

Aperture Preview Generation Error

Hi folks,
I've a couple of images and a movie that are queued up for preview generation, however when Aperture 3.4.3 reaches them it stops responding, I get the colour wheel, and my CPU goes into overdrive. I have to force quit Aperture.
I've been getting round this by simply holding shift to stop preview generation starting automatically when launching Aperture. But its not a solution, and I need to get it fixed.
I've removed the offending files from the Aperture Library manually and relocated them for now. Other applications seem to be able to view them without problem.
The problem is Aperture still thinks the images are present in the library (though marked as missing) and trys to generate preview still. I've tried to delete them through Aperture, but the moment I select them Aperture stops respondning again, and I have to force quit again.
I've repair the permissions for the Library, rebuilt/ repaired the database. but I still have the same problem.
My HDD has a clean bill of health, ran disk util to verify and fix permissions etc.
Any ideas how I get rid of these problem files?

I can open Aperture using the Shift key, everything works fine. Preview generation does not start. This is how I've been managing to use Aperture recently.
It's when I start normally, the previews start generating within 15 secs. Then Aperture freezes.
I've unticked Maintain Previews for both Projects (top level) and the projects that the problem images reside in.
When I tried to manually remove the images, I located them within the Previews, Thumbnails and Masters folder using Spotlight and moved them to my desktop. I made a note of where they came from and have replaced them.
However the issue I'm having remains unchanged, both before removing, after removing, and replacing them. As I understand it the thumbnails and previews are generated on request, and as such are temporary files anyway.
I've read articles mentioning deleting these folders entirely to resolve other issues, but I don't want a 15 hr preview marathon only to get stuck on the same images. Might be worth a shot if I can't find another solution though.
What I have realised though, is that these images are referenced from my old iPhoto Library before I jumped on board Aperture, wonder if I can delete from iPhoto instead of Aperture? I'll report back.

Acrobat Pro 9 - Disable thumbnail preview in PDF file icons on Desktop

After upgrading to Acrobat Pro 9, the file icons of PDF files on my Windows 7 desktop changed to showing a thumbnail preview. I want to get the standard PDF file icon back for all PDF files. Can someone please tell me how?
Thanks.

Did you ever find an answer for this??? I had the same issue and was searching for an answer. I saw this and since I fixed mine I thought I would tell you what I did. Also, in case someone else finds this and needs an answer.
Opened Windows Explorer -> Tools -> Folder Options
Go to the View tab
Check "Always show icons, never thumbnails"
Hit Apply
All your PDF files on your desktop should now show with the generic PDF icon.
Reverse this to get the preview icon "thumbnails".

Display thumbnail preview for images in a Document Set

I have a Document Set with Images in it. I would like to show a thumbnail preview of the images in the view of the files in the document library. I added the Thumbnail Preview column but it just shows a large File Icon.

Hi,
According to your description, my understanding is that you want to display the picture of the images in the document set.
I recommend to create a hyperlink type column and format URL as picture to show the images in documents set.
Thanks,
Victoria

Thumbnail Preview for RAW Files Not Appearing in Bridge

Hello,
I'm running Adobe Bridge 5.1 on a Mac OS 10.9.2 (recently upgraded to Maverick) and I can no longer see thumbnail previews for my RAW files (which include .NEF, .CR2 and .RAF) though as of a few days ago this wasn't a problem. Not sure if it's related to the Maverick upgrade... but FYI, I do see thumbnail previews for .TIFF and .JPEG files.
I've already purged my cache generally and have also as a test chosen a local file to purge - that didn't work.
I've restarted Bridge at least 2x by pressing and holding the Option key.
I've also checked for Bridge updates - everything is up to date.
My Cache Options (within Preferences) are set to "Keep 100% Previews in Cache" and "Automatically Export Cache to Folders When Possible" - both checked.
Also downloaded the Adobe Camera Raw and DNG Converter 8.3, installed it but that didn't work.
I can't seem to find my Bridge cache folder or at least what's in the Library's "Caches" folder doesn't include anything for Bridge - see screenshot below.
Please help! Thank you in advance.

To me it seems related to your Adobe Camera Raw (ACR) converter. Clue inhere is you only miss the Raw files and have no problems in seeing other formats like jpeg and tiff.
The screenshot you delivered is from the wrong library, however, this same library (the one on system level) also is the location where you should be able to view the correct version of your ACR plugin. The path: library (same as per your screenshot)/Application support/ Adobe/ Plug ins/ CS6/ File Formats. inhere should be only one version of Camera Raw (called: "Camera Raw.plugin") and this should show version 8.3 (141).
I'm not sure about your bridge version number, Bridge 5 comes with PSCS6 but my most recent version of Bridge is 5.0.2.4.
Anyway, if you have only one ACR (8.3) installed in the above mentioned path then you might want to try to delete the Bridge plist file and Bridge cache file manually.
For this you have to Quit Bridge and find the user library (by default hidden, use menu Go in Finder and press option key to reveal).
Inhere find the plist file (user(your user name) / library / Preferences and inhere find and manually delete the file called: "com.adobe.bridge5.plist"
The in same user library find Bridge Cache. User/Library/Caches/Adobe/Bridge CS6. Inhere are 2 files, the adobe Bridge plug in cache and the folder called Cache. delete (or move outside libray) both items.
The restart Bridge (If needed also again hold option key to reset preferences) and this will create fresh files for the previous deleted items, leaving you with an almost out of the box factory set version of Bridge.

(SOLVED) Taskbar thumbnail preview disappears quickly

I have windows 7 RC on my laptop, Dell 1501.
When I start one or more programs from the taskbar and hover my mouse pointer on them I can see thumbnail previews.
The problem is that thumbnail previews disappear too quickly even though my mouse pointer is still on the opened program in taskbar.
I have to move my mouse so I can get another quick preview.
I notice that if I click on an empty space on the taskbar with the left mouse button, and then point to an opened program the thumbnail preview stays for as long as my mouse pointer is on the program.
Does anybody have that problem?
EDIT:
I notice something else,
if I open regedit or computer management and one of them is active, all other opened programs on the taskbar have long thumbnail preview.
But if for example windows explorer is the active window on taskbar, thumbnail previews stay for a short time.
SOLUTION: dell 1501 specific and may be bios version
1. shut down the laptop
2. remove the power supply and the battery
3. press and hold the power button (I pressed it 2-3 times and kept it pressed for about 1 second) --- obviously the laptop will not start.
4. plug in the battery and the power supply, start the laptop and check if the problem is gone.

teeqeela: "I can't believe it! Same dell, same problem, same solution. Thanks man!"
If that was for me, my pleasure.
Noel Carboni: "I'd be curious to know whether you've found the reason it was happening"
I'm curious about the reason, but not prepared to spend the time to find it; I don't think we'd learn enough from it to justify the time. Back pre-Windows pre-Internet I spent weeks painfully debugging. It's
hugely more complicated now, the Internet finds most things quickly anyway, and the tedious tracing doesn't bring many useful insights. I can't give answers, I'll just repeat the facts - any proposed answer must address them. Some details in the numbered points
I made a few messages back. The problem first manifested (for me, and I believe for others) some months after installing Win7 on Inspiron 1501 (specifically that machine). It's cleared by removing all power, and by a couple of software tricks (disable gadgets,
registry hack). Once cleared by power removal, it stays clear for weeks (not months) then recurs (don't yet know how permanent other fixes will turn out to be). One thinks of things such as some bit in system memory that gets set somehow, and never reset until
power is removed (it might be a memory location always alive and watching for a wake-on-lan or other wakeup event), which Win8 expects to find reset. But why the month's delay? Win7 (32- and 64-bit) works fine on Inspiron 1501, but is not officially supported,
and some non-Dell drivers must be used; they work fine. I could go on till the cows come home, but I've got myself a usable machine, and told others about it, so that's it.

Zoom the images in asset library thumbnail preview column in display form

Hi,
I have a requirement is:
i have an asset library with 1000 of images and on search of it in the results page, we customized to display the thumbnail preview of that image with title link which links to display form. in the search results on click of thumbnail image it will zoomin.
we need to have the same functionality on display form also. how to achieve it?
Aruna

How are you doing this?
If you delete in iPhoto and empty the iPhoto trash then all versions of the photo are gone
If you use the finder to delete photos then you trash your iPhoto library and will ahve to start over
As to faces - that is not an option so all iPhoto users have face thumbnails
And it is very strongly recommended that you simply stay out of the iPhoto library - there are NO user servicable [parts in it and going into it endangers your photos and other data

Thumbnails & Preview filenames do not match Master filename

Hi - can't find any threads regarding this...
Basic problem is that Aperture is not renaming the Preview & Thumbnail filenames when it renames images on import - anyone else experiencing this problem?
I have a managed Aperture Library (2.1.3). I rename my image files on import using the Import dialogue set to Custom Name & Counter and Apply to Master filename checked. However the Preview file, the Thumbnail file and the Finder folder holding the images do not get renamed.
Since the Media Browser uses the Preview files rather than the Master files when importing images into other apps (eg. Pages or uploading to a blog) the files used all have the wrong names.
For Instance:
I have a canon image file named IMG1234.JPG.
I import this file to Aperture and use the import dialogue to rename to Custom Name SUNSETNEVADA.JPG (with apply to Master Filename checked).
In Aperture what I see in my project is SUNSETNEVADA.JPG as the Version Name and the Master filename - as expected.
However the Thumbnail & Preview files are still called IMG1234.JPG - you can't see this directly from within Aperture you need to open Finder and drill down thru the Library package where you find that your Master file is called SUNSETNEVADA.JPG but it lives in a folder called IMG1234.JPG with a Thumbnail file called IMG1234.JPG and a Preview file called IMG1234.JPG.
I then open Pages and open the Media Browser.
I select Photos, and then my Aperture library, find my project and select SUNSETNEVADA.JPG.
The file that gets imported into Pages is the preview file called IMG1234.JPG.
The same happens in any situation where I use the Media Browser to browse the Apertuer library and import images, because the Media Browser always uses the Preview file.
The only work around I have is to export images directly from Aperture and then browse the Finder to import them to other apps - avoiding the Media Browser and Preview files altogether.
I have notified Apple Pro Support who claimed to be unaware of this error.
If you have seen the same problem please notify Apple Support.
Any thoughts or solutions welcome. Thanks

I am seeing the same thing, as I have lost all my masters and can only get my pics by copying preview files, which all have the old names.

Upgrade to 2013 leaves "Images" library without Thumbnail Preview working

The issue I am seeing is occurring after an update from SharePoint 2010 to SharePoint 2013. The library is a publishing library created in 2010. These features are enabled in 2013. Looking at the "Thumbnail Preview" column in any view shows the
generic sheet of paper icon. Viewing the images in the "Thumbnail" view shows the thumbnails correctly. The images for the list in question are all .gif. As far as I know those are the only ones failing, but we could have missed some other filetypes.
I've tried moving a document to a newly created Images library and the preview shows as expected. So I believe I've pretty easily demonstrated that the actual image is not a problem and that SharePoint 2013 can render it. However, it's not a workable solution
to move these files.
If I open the library with Fiddler, I get a 404 error for 256_icgif.gif. From there it's been sort of a dead end as I wouldn't know where to test and see if that's part of the issue.
This is our dev environment before upgrading to 2013 so we're looking for a fix we can perform during or before the upgrade.
Thanks!

Hi Christopher,
Casting my mind back to the Beta, I hit something similar during a test upgrade and if I remember rightly it was to do with the content type mappings that came across. There are two content types Picture and Image which behave differently, so try swapping
the available content types in the library and changing that.
Paul
