QuickTime Files - No Icon Preview

I like in Finder the way that it shows you Icon Previews for images, so that you can see a thumbnail of the image when you're in icon view mode.
However, QuickTime files don't seem to have an icon preview, which is a shame. Is there any way to enable this? It would be great for all the Poster Frames to show up as the icon preview.

Open your file with QuickTime Player.
Use the controller to find the image you want (arrow keys will step through frames).
Command-C (Copy).
Switch to the Finder and highlight the QT file. Open the Get Info window.
In the upper left corner you'll see the QuickTime icon. Single click on it and it will "highlight".
Command-V (Paste).
Custom icon preview using an image from your file. If you keep a lot of videos in a single folder set the Finder icon preview to 128X128 and it's easy to find the "right" one.

Random Flashing Color Bars within Quicktime Files during RAM Preview Only

I have been getting random color bar flashes within quicktime files in AE CC during RAM previews using Multi Processor rendering. Files other than .mov seem to not have this issue (although I have seen it twice...though it may be due to quicktimes in the comp). The rendered output using MP rendering is completely fine. If I turn off MP rendering the ram preview is fine. The source material is coming off a RAID 5 at 600-800MBs, I have moved the footage to a local SSD and a standard spindle drive with the same results. I have tried everything.....disabling GPUS in preview, disabling Fast Adaptive Preview, Disabling Disk Cache, Adjusting MP settings and RAM usage per core, disabling hardware accelleration of interface, adjusting gpu memory useage, every codec under the quicktime wrapper including uncompressed codecs, updating Blackmagic drivers, updating quicktime, limiting how many processors Windows 7 64bit can see, resetting AE preferences. I even installed After Effects clean on my second boot drive for gaming with no plugins or other apps, same issues. Have discussed this heavily with tech support at Adobe and they are working on it for a few days before getting back to me. When I got off the phone the tech was of the mind that I have too many cores for the Quicktime codec to handle.
My system :
Windows 7 64bit
Dual Xeon E5-2687W: 16 Physical cores and 32 cores with Hyperthreading
32GB 1866 DDR3
3xNvidia GTX 680 4GB cards
SSD boot and seperate SSD media cache drives
8TB internal SAS RAID 5 using a ATTO card
Blackmagic Deckline Extreme 3D+ card
Any help or thoughts would be greatly appreciated as this is a huge boon to my workflow. Having purchased a $12K system for grading and rendering....not being able to use the ram preview in AE with multiple cores is a huge inconvenience.

Here is the requested taskmanager screenshot. As my test comp only has a single duplicated quicktime in it, it renders too fast to really catch the AE instances doing anything. So this is from a heavier comp. Settings are as pictured above with 3GB per core using 8 total cores of the 32. It did flash the bars.
Here is what I tried tonight:
- Followed the link on Quicktime having trouble with too many processors. Using MSCONFIG I dropped the recognized Processors to 21, 16, and 8 and tested all three settings. Each had the flashing bars issue. Again as usual, at random, sometimes 3 previews before showing up, sometimes the first preview run. I have noticed that the ram previews that take a little longer seem to be clean. Then sometimes it seems to fly through the preview, grabbing large chunks on the green progres bar above the timeline, or many little chunks very quickly....these are usually the preview runs that will show the flashing bars. I make a point of purging the cach between each one so it doesn't remember, plus I have disk media cache off, but sometimes I get the feeling it's remembering bits.
- I removed all the Quicktime Components from the QTComponents folder and tested it. Flashed the very first run without any quicktime components.
- Followed the Firewall or TCP instructions and made sure everything was allowed through ZoneAlarm. However I could not find the QT32 Server listed anywhere or figure out how to add it. No matter because I closed and force quit all of the firewall processes as well to make sure. Still flashed.
- I followed all the advice on the landing page for Quicktime-related problems
- I also tested out ram previews again thourougly with the same clip but converted to a Tiff sequence. No matter what I tried there was never any flashing in the ram preview with tiffs.
- I also re-tested the clean render output. Made a ram preview with the flashing bars, then without purging rendered it out to a quicktime file and there were no bars at all in the rendered output. I even tried duplicating this render output 6 times in the render queue and rendered them all at once. Not a single one had a flashing bar frame. I even played all 6 1080P uncompressed 4.2.2 YUV 10bit pieces off the RAID with no dropped frames or hichups.
- Killed every process in the taskmanager but for essential windows processes and the flashing bars were still present
- Set the priority to Real-time for every AE process including Adobe QT32 Server, Dynamiclinkmanager, and all the AE processes. Still flashed.
I am now considering disabling two of my GPUs in the device manager. However I'm a bit worried about disabling the wrong one and being locked out. Any thoughts? Is the computer to powerful for some process somewhere? Why only in RAM preview? Thanks again.

Quicktime files only show up as icons, not as thumbnails in my files

None of my quicktime files appear as thumbnails (in their folder), even though I have selected 'show icon preview' in the view options menu. I would love to see the first frame of the video clip to help sort my clips.
I've tried posting this question in the quicktime formum with no response. I'm hoping someone can assist me with this. I would also be amenable to posting it in a more appropriate forum, if someone has such a suggestion. Please advise. Thank you in advance.
Fredsel

Mine are mixed - some QT files show as icons, some as thumbnails. The same is true of .wmv files and other formats - some do, some don't.
I have a feeling this may be related to a long-standing problem with the way OSX generates/displays file icons. I'm no expert at all, but I think that it has to do with the data contained in the resource forks. However, I am fully open to correction on this.
Advice elsewhere in these Discussions suggests trashing the Launch Services plist and restarting or logging out/in: see below for a suggestion I found in another topic.
delete the file: homedirectory/library/preferences/com.apple.LaunchServices.plist and log out/in
I've just tried this myself, and it did not appear to work for me - it apparently fixed just one file and not the rest. However, when I did "get info" on the unchanged files and used edit/cut on the file icon, it then changed the QT icon into a thumbnail.
This may have nothing to do with trashing the LaunchServices plist, but I suspect it might as this didn't happen when I tried cutting the icons earlier. However, it doesn't seem to help with other applications (eg vlc).

Icon previews - mp4 files

Leopard can show icon previews for mp4 files now. But most of my mp4 files start off with a few frames of blank screen - so my icons (when I choose to display them) are just an ugly little black square.
Anyone know if you can specify a frame of the mp4 movie that you want to use as the icon??
Thanks.

Actually, I've just answered my own question!
A bit long-winded...
Start to play the mp4 in Quicktime.
Pause at a suitably artistic moment in the action.
Shift-cmd-4 to take a selection of the screen and grab it as a file (I have my system set so it grabs it as a jpg.)
Open that jpg in Preview.
Select some of the image and cmd-C to copy it
Cmd-I to open the 'info' on the file in question.
Highlight the icon in the top left corner.
Cmd-V to 'overwrite' that with the image you have just put on your clipboard.
It works! But like I said, it does seem a VERY circuitous route.
Also seems to highlight the fact that you can use any size of jpg image as an icon. Is this something new in Leopard?
Anyway, I'm sure there's a clever person out there who knows how to do this 'properly'...?

Can you Choose a Particular Frame for Quicktime Icon Preview?

Is it possible to choose a specific frame for a Quicktime file icon preview? A lot of movies start out with a black frame and the icon preview in Finder is therefore a black square. I would like to be able to choose the frame to use for the preview.

I don't know if this is possible (ask in the QT forum) but you can trim the movie with QT player to get rid of the black frame at the beginning of the movie. you can also take a screenshot of any frame you want and apply it as a custom icon to the movie.

QuickTime Thumbnail Icon Previews?

Is there any way to get automatic thumbnail icon previews for QuickTime files in Windows? You get them automatically for MPEG, AVI and WMV files, but not for QuickTime files. Any help would be greatly appreciated.

Why having displayed both generic icons for the PDF and JPEG files and automatic preview of the JPEG files in an ordinary folder are mutually exclusive in Win7?

In Win7 Pro all my:
PDF documents, with the 'Large Icons' option chosen in the View tab, display contents of their first page with a tiny thumbnail in the icon's lower right corner, instead of a generic PDF icon.
JPEG files show Icon size photos, instead of a generic Nero 9 PhotoSnap Essentials icon.
Folders containing the JPEG photos, however, automatically show preview, when opened, which is desirable feature.
I found that the Win7 option "Always show icons never thumbnails" in the View tab: Windows Explorer -> Tools -> Folder Options, (where ironically the present 'thumbnails' have nothing to do with 'Thumbnails' from the View option in WinXP), causes the unwanted effects described in points 1 & 2, when unchecked.
Checking this option solves the problem of the PDF and Nero icons. This time, however, I can only see a Nero 9 PhotoSnap Essentials icons, instead of photos preview on opening of any standard folder with the JPEG photos.
Did I make a mistake somewhere or maybe Microsoft made changes in Win7 with respect to WinXP, which make it impossible to have both the features working at the same time?

Hi,
You can install the Win 8.1 software drivers using this link.
http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?cc=us&dlc=en&lc=en&product=4323648&task=&
Once installed, it should have the same features as the Win 7 drivers for scanning.

No prores422 Quicktime icon preview in finder OSX Mavericks

I upgraded to Mavericks osx 10.9 and now I no longer get a thumbnail preview on my prores quicktime files in the finder o. I do get a preview with any other type of quicktime codecs the only affected files are prores files. I shoot a lot on the blackmagic cinema camera and it's not good for me just to see a Q on those thumbnails. I'm a Final Cut Pro X user so I have the proper codecs to view the files. I have tried the view options and it does not affect Prores files. I've also downloaded the latest codecs from apple. So I want to know I'm I the only person this is happening to? I'm thinking I may need to reinstall mavericks but before I do that I need to know if anyone else is experiencing this? I have attached a screen capture to illustrate what I'm talking about. Quicklook does still work on the prores files but I need that thumbnail.

I've tried reinstalling Mavericks and I'm still having this issue. I'm considering wiping my drive and going back to Mountain lion. Qucktime player in Mavericks seems to suck. I'm having several other issues playing back older quictime files. Most play in Quicktime 7 but a lot have no quicklook previews. The sheer volume of prores files I shoot makes this extremely inconvenient for me. How can Apple not support their own Codec????

Icon Preview is not shown for mp3 files in finder

Hi. Recently I noticed icons of mp3 files are no longer as used to be in finder. Previously I had a dark music note icon and when i hover my mouse there was a play button. Now I only see itunes icon in mp3 files. "Show Icon Preview" option is enabled, and i can preview image and pdf files in finder. But something happened to the mp3 files. It is very annoying. Please guide me to get back the good old icon preview for mp3 files.

Displaying icons as previews of files
In Finder windows and on the desktop, the icons for files can appear as thumbnail previews of the file contents. For example, instead of seeing a generic icon for a PDF file, you can see a miniature version of what’s in the PDF file. If you “hover” over the icon for a movie or sound file, you’ll see a Play button, which you can click to view the movie or hear the sound. (If you don’t see a Play button, enlarge the icon.)
NOTE:If you’re using Cover Flow view, you’re already previewing files and don’t need to change any settings.
To display icons as previews:
To work with icons in a Finder window, click the Finder icon in the Dock.To work with icons on the desktop (the background area of your screen), click the desktop.
If you’re working with icons in a Finder window, click one of the View buttons in the toolbar to select icon, list, or column view.
Choose View > Show View Options.
Select “Show icon preview.”
If you’re working in a Finder window, you can also set the following options, depending on which view you’re using:
In Icon view: Use the “Icon size” slider to adjust the size of the preview image.
In List view: Click one of the two “Icon size” buttons.
In Column view: To see a larger preview in the adjacent column, select “Show preview column.”
NOTE:The Finder may not be able to show a preview for some files.
Another way to get a quick preview is to select one or more images, and then click the Quick Look (eye) button in the Finder window toolbar, or press the Space bar.

Icon preview not working for occaisonal file

Hi y'all.
I'm using Illustrator CS4 and there is a particular file that I cannot seem to save with an icon preview.
And yes, I've selected pdf compatibility, with no success.
Could it be that I'm resaving an old file that was originally created in Illustrator 10? Could it be related to the use of many patterns?
Any other suggestions?
B.

Hello to both of you. Sorry for the delay in response!
Yes, I've tried doing a "save as" - even to different places on my hard drive.
And yes to the other suggestion: my folder prefs do say show icon preview.
Any other thoughts? Could it have something to do with the patterns I've used? Patterns can do weird things, I hear....

Prev "previewed" files in 10.6 dont scale via "show icon preview" function

1. use DropIcon 3.0.2 under a lower version of OSX than 10.6
2. import your "preview built" files into 10.6 (notice also that files that have a preview built into them are larger in file size than the same file which doesnt have it)
3. scale a folder full of images to for example - 180 px squared
4. notice that 10.6 cant build a new preview based on the new size
how to "show icon preview" files which have been previously "preview built" by apps like DropIcon 3.0.2 ?
This would be very useful....
TIA

You may not think of icons as 512x512, but Apple now does. The transition started in Leopard, and is now complete--pretty much all of Apple's icons will now go to 512pixels in the various and sundry places they are displayed, from window views for Icon, CoverFlow, and the preview pane of Column view, to the GetInfo preview, to Spotlight results displayed in icon view.
As to your own custom thumbnails: if, as mentioned previously, you used Photoshop with the option to save a custom thumbnail, or you used a dedicated program to save a custom thumbnail for an image file, then those custom thumbnails were added to the image file as a resource fork. WAY back such custom thumbnails were 32x32 pixels. In the more recent past they were 128x128. Indeed, that is still the size used by Photoshop when it adds a custom thumb.
If the Finder is displaying any view that shows a preview of the file it will either display the custom thumb that is part of the file, if one is present, or draw its own preview if no custom thumb is embedded in the file. And if it uses the custom thumbs they will NOT scale upwards in any pretty way, beyond whatever their original size was--they'll just get pixalated. The advantage, if you don't need to be able to scale up to 512, is that the display of a folder full of images with custom thumbs is instantaneous, while a folder full of images without custom thumbs may take a noticeable amount of time for all of the previews to be drawn (you can see them appearing as you scroll the folder). The disadvantage to custom thumbs, as you have discovered, is that they don't scale well. If you want to be able to scale the preview thumbnails in various Finder views, you need to remove the custom thumbnails you have added, either via the save option in Photoshop, or with your third party program. You can't tell Finder to ignore them: if they are present Finder assumes you want it to use them, rather than its own preview function.

How can we get icon previews back for alternate media files?

How - if ever - can we get icon previews back for alternate media files?

For the folder you're in do you have the View option set as shown in this screenshot?
What do you mean by alternate media files?

Incorrect file icon/preview for downloaded files

Hey all,
I've recently upgraded to Mavericks and I've noticed an issue where files I've downloaded from the internet will sometimes appear as they should on my desktop with the appropriate icon based on the file extension or with the appropriate icon preview, but in other instances the file icon looks like the one in the attached screen shot. The file still opens fine and behaves normally, but the icon is weird and makes it hard to quickly find when I'm looking or a specific photo or type of file. Any solutions?
Thanks,

It works as it should.

Image files no longer appear as "icon preview"

Previously I could view all my .png image files in the "icon preview" mode in Finder.
I must have accidently changed some setting where I can no longer view .png files in the "icon preview" mode. I just get the generic .png icon to appear in finder. I have the "show icon preview" item checked in view options, and most other image files appear as icons...just not the .png files.
Any thoughts? Thanks.

You could have turned "show icon preview" off and set that as a default.
In a folder with images, set to "icon" press command+j and make sure that "show icon preview" is ON.
If it's ON and still no luck, turn it off, close the folder, reopen and try again.
It seems that some images have previews in them (from Photoshop or similar) and will show previews even with the above option set to off. Others need the option to be ON.
Also, what do you see if you select one of the preview-less images and hit the s p a c e ?

Icon previews wont show for some mp3 files

For some reason I have about 30 albums (out of around 1000...which isn't too bad of a ratio) that wont show the album art for the icon preview. Instead it shows an image of an old iTunes logo, I can't remember which version of iTunes, but it's the version that has a green note on top of the disc. Is there a way to fix this? Thanks.

Do you have an album specified for the mp3 song. I've noticed that if I only have a couple of songs for an artist and none has the album specified, they don't always show up. If I add the album, they will sync the next time. Hope this helps.
