Black Thumbnails for MP4 files in iPhoto

The MP4 files from my digital camera show up as black icons in iPhoto 09. I don't recall this happening before Snow Leopard was installed. Some MP4 files work show thumbnails. Regardless, all the MP4 files DO open via iPhoto, and the thumbnails can be seen in the Finder.
These files are MPEG4 h.264/AAC codec. If I run these files through MPEG Streamclip to remake them as the same file type, then the thumbnails DO appear in iphoto when reimported. Comparing the "get info" data on both types of the files (ones with black thumbs and ones with real thumbs) shows no difference in file types.
Short of having to convert all my small videos and reimporting them, or getting another camera who's MPEG4 is consistent with iPhoto, I'm at a loss. I have done a rather complete internet search and several others report a similar problem. The camera I am using is Samsung TL34HD.
Appreciate any help short of what I am currently doing (converting to the same file format and reimporting the videos in batches).

thanks larry. when i open in quicktime and go to the first frame, it is not black. also, for some reason, when i import the movies into itunes, the thumbnails show up fine (i.e. no black frame). i'm guessing that it has something to do with how iPhoto generates the thumbnail (vs. iTunes), but i don't know enough to change these settings.
if the first frame is in fact black, do you know if there is a way to force iphoto to use something other than the first frame when generating thumbnails?
thanks very much.

Black thumbnails for video files

hi, i'm having problems with black thumbnails showing up in iPhoto 06 for mp4 video files
mpeg files work fine, and the same mp4 files actually work in iTunes (meaning iTunes generates a correct thumbnail but iphoto thumbnails are black)
does anyone know how to correct this?
thanks very much

Thumbnail images for MP4 files vanished again - how can they be restored?

My thumbnail images for MP4 files have vanished again and could you tell me how to resttore them please? I am running Windows 8.1 and IE11 Browser and use the Real Player to play these files. When I run a flash test it says one minute it is not installed in the browser and the next test confirms that it is installed. Is this a known problem with Windows and can it be fixed by adjusting a setting somewhere. Thanks for your help.

Enable Compatibility View for IE: http://windows.microsoft.com/en-us/internet-explorer/use-compatibility-view#ie=ie-11 and the plugin will be recognized.

IPhoto 11, Black Thumbnail for all Faces

In iPhoto, when I go to Faces there is a black thumbnail for all faces. If I double click to go to the actual fotos of one of the faces (names), the thumbnails are also black, if I double click the actual individual foto then you can see the actual foto. I have reinstalled iPhoto but it still shows onlt Black thumbnails for all faces (names).
Please help.

haarrrrummmm... don't know why I'm not able to edit my own posts, but there you go...
Rebuilding is only rebuilding if you get a dialog box showing 4 options. If you don't see this, then you may not have options and cmd keys depressed correctly (long enough etc) at startup of iPhoto.
You should see a dialog box presenting four choices:
repair permissions,
repair thumbnails
repair database
rebuild database
(Doing this from my head so the order may be a bit different)
Anyhow, start with repairing permissions, then thumbnails.
Repairing thumbnails will take time, especially on bigger libraries. Allow the machine to finish the task.
Repairing and rebuilding database are the big guns here. Make backups before letting these loose.

No Thumbnails for AVI files in organizer

My AVI Video clips are not showing thumbnails in the PSE 11 Orgazizer.
Here is what I have observed as I have been troubleshooting this:
The files are MJPEG.
When I double click on it in the organizer window, I get audio, but no video.
If I open the file for edit in Premier Elements, the video thumbnail shows up in project assests and the video correctly plays in the Premier Elements editor.
If I double click on the files in Windows Explorer they open up in Quicktime Version 7.
The thumbnails for the files show in up windows explorer when I browse to the folder they are in.
I selected a file in PSE, chose 'Export to New File" and the file that I created by doing that showed a generic Quicktime icon without the thumbnail in windows explorer. When I double click on that file it correctly plays in Quicktime.
Selecting "Update Thumbnail" has no effect.
Thumnails are corrctly showing for .mov, .mpg and .mp4 file types.
Any one have any ideas what is going on with the organizer that might be causing this beavior or is this a know limitation of PSE Organizer. What is the point of having the organizer supporting video If I can't see the video without opening it in the Premier Elements Editor?
I am providing the "Systems Info" if that helps anyone.

I do not use Organizer, but instead Adobe Bridge (included with some other Adobe programs, like Photoshop, InDesign, Illustrator and Premiere Pro), or ThumbsPlus (Cerious Software), and find that some AV formats/CODEC's just do not display thumbnails. I have had that issue with some, like MPEG-1 files, some WMV files, almost anything with DivX, or Xvid.
I have not used any MJPEG files, so cannot comment on them, but have helped others Import and edit those (never tried to work with any in Organizer, Bridge or ThumbsPlus), and in those cases, it usually boiled down to having the exact MJPEG CODEC installed. As each camera mfgr. seems intent on tweaking the MJPEG CODEC, it is normally possible to Import and edit, if THAT particular MJPEG CODEC is installed, and usually from the camera's utiltiy disc. Other times, the generic Morgan, or MainConcept MJPEG CODEC's have worked - though that seems to be less often, as Nikon, Panasonic, and others, keep tweaking.
As for the display of any problem AV files, it is usually an inability of the organizing utility to find a proper display, though in some cases, there IS a display, but the first Frame of the AV file is black, with a Dip-to-Black (in this case basically a Fade-in) Transition.
Good luck, and I wish that I had a fail-safe way to always display a thumbnail for ALL AV files, and even better, the ability to set the Poster Frame to what I wanted. So far, no organizer utility, that I have seen, can display thumbs for ALL AV formats - some will handle some AV formats/CODEC's, that others will not, but none has been perfect.

I can see my thumbnails for my events in iphoto, but when I click to open the folder, no photos show up. However, when I hover over the thumbnail, it shows the flicker of images
that should be inside the folder, as well as # of images in each folder. It also occasionally says the following when I try to even open iphoto: "Your photo library will not be readable by previous versions of iPhoto after the upgrade. The upgrade process for very large libraries may take an hour or more to complete." So, I am scared to hit "upgrade" for fear I will never recover any of the images as the wording in this quote seems odd. The photos are not in the trash. Did I lose them all? Do you know if/how I can retrieve them?

iPhoto 08?
Try these in order - from best option on down...
1. Do you have an up-to-date back up? If so, try copy the library6.iphoto file from the back up to the iPhoto Library (Right Click -> Show Package Contents) allowing it to overwrite the damaged file.
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.
3. If neither of these work then you'll need to create and populate a new library.
To create and populate a new *iPhoto 08* library:
Note this will give you a working library with the same Events and pictures as before, however, you will lose your albums, keywords, modified versions, books, calendars etc.
In the iPhoto Preferences -> Events Uncheck the box at 'Imported Items from the Finder'
Move the iPhoto Library to the desktop
Launch iPhoto. It will ask if you wish to create a new Library. Say Yes.
Go into the iPhoto Library (Right Click -> Show Package Contents) on your desktop and find the Originals folder. From the Originals folder drag the individual Event Folders to the iPhoto Window and it will recreate them in the new library.
When you're sure all is well you can delete the iPhoto Library on your desktop.
In the future, in addition to your usual back up routine, you might like to make a copy of the library6.iPhoto file whenever you have made changes to the library as protection against database corruption.

Thumbnails For QuickTime Files In Windows XP?

Windows XP shows thumbnail previews of video files in Windows Explorer. However, it doesn't show thumbnails for QuickTime files. Does anyone know why this is? Does Windows Vista also share this problem? Is there a way to add this feature to Windows XP?

One other thing to explore - do these particular files begin with Black Video?
Good luck,

How do i change the file preview image for mp4 files? I replaced the image but it doesnt show in my dock, instead it shows the first still of a movie

http://imageshack.us/photo/my-images/21/screenshot07m.jpg/
http://imageshack.us/photo/my-images/39/screenshot04s.jpg/
pls help. i change the file preview of a movie file, and it shows that i have changed the preview in finder but when i open the folder on my dock, it shows the still of the movie instead.
the image shows the film the hangover as an example. the movie poster is visible in finder, but reverts to a default movie still from the dock. this only seems to occur for mp4 files.

its nothing to do with itunes, its movies form the internet. i got the file preview by taking an image off the internet, pressing command c and pasting it on top of the small icon in the get info section

I guess you are calling BDC right after some event which is locking the data or before the commit of previous data could happen. Sometimes data update needs time. You can try using WAIT statement right before it and wait for 1 or 2 seconds and see if it works.
If it does, I would recommend you to check the lock on the corresponding object and when lock is removed update the data as waiting for 2 seconds for a larger set of data will just make the program a bit slow. Depends on the amount of data though, if it is just one set of transaction, you may use WAIT for 2 seconds.

API to access and set properties for MP4 files

I am looking for some APIs in Visual C++ to use in Visual Studio to set
and get properties for .mp4 files. Can anyone help me in this regard?

Hi Rahul,
Try using the Windows Media Format SDK with help from the below document:
http://blogs.msdn.com/b/tims/archive/2004/03/28/extracting-metadata-from-windows-media-files.aspx
Alternatively, you can give a try to ffmpeg libraries for a open source alternative.

PSE 12 Has stopped showing thumbnails for new files

PSE 12 has stopped showing thumbnails for new file imports. Have Windows 8.1 update

In the PSE12 Organizer, the last files imported show an hourglass thumbnail. I am importing from the camera card. Other images have the correct thumbnail. I see the spinning icon on the lower bar showing it updating the catalog. Thank you for your assistance

Cs6 bridge not showing thumbnails for raw file

Just upgraded to CS6
cs6 bridge not showing thumbnails for raw files.
Can see thumbnails in CS5.1 bridge and LR 4.2 which fortunately i did not uninstall.
Bummer since I am up against a hard deadline.
Really Sucks

We can't know. You are not offering any system information or e.g. info about what image files you are working with. Since they do show up in your otehr programs, my assumption would be that you need to switch the Camera Raw engine back to the 2009/2010 version in Photoshop and not use the default new 2012 one. Perhaps your thumbnails will appear then....

Thumbnails for mkv files

After installing Perian and Movist (a video player software), I believe that I have solved most of the problems for mkv files in Leopard. I can play .mkv videos in either Quicktime or Movist, and I can tap the spacebar to quicklook the video when browsing in Finder. But one thing that I cannot change is that the thumbnails for these files remains a generic icon, unlike .mov files that have thumbnails of the screens of the movie. Thus when I'm browsing with cover flow, I can only quicklook the mkv files in pop-out window, rather than playing it in the upper part of Finder as what I can do with .mov or .avi files.
Is there anyway to improve this? I know Mac may not support .mkv files as good as .mov, so I'm wondering if there's any third party softwares that I can rely on to resolve this problem? I'll be grateful if somebody could shed some lights on this.

Hope someone knows it. Thanks again!

How do i view thumbnails or .mp4 files in my windows folders? for quicktime

i noticed since switching my cameras i used to be able to view thumbnail pictures of my movies.
my new computer uses .mp4 files for HD movies so now my files only show .mp4 icon instead of a thumbnail for the video.
anyways to fix this?

According to Adobe's supported-camera list, you need at least ACR 8.1, so 7.4 is too old:
Camera Raw plug-in | Supported cameras
According to Adobe's Camera Raw list, Elements 11 only works up to ACR 8.0:
Camera Raw-compatible Adobe applications
So you have to buy PSE12 or use the free DNG Converter to convert the ORFs to DNGs that will then have enough information in them to open in your older Elements version. You can download the latest DNG Converter near the top of this page:
http://www.adobe.com/downloads/updates
If you need an older version due to your OS being too old, then you can download older versions from the DNG Converter section further down the page but make sure you use at least DNG Converter 8.1.
