Can't open .mov files in quicktime anymore

I can't think of any system changes that I've made recently but a few days ago I was able to open .mov files with quicktime and now I can't. I get the following error when I try to open one. Error -1856: an unknown error occurred (filename.mov) I've uninstalled quicktime, rebooted and reinstalled with no luck. I've searched these forums and googled the error number but can't find anything. Does anyone know what might be going on? Thanks.

Actually, I can't open anything in quicktime anymore. I've tried opening avis, mov, mp4 and m4a files... all give the same error message and number. I've reinstalled both qt and itunes but no luck.

Can't open movie files in browser or email

Hi, I'm not sure if this issue has been dealt with yet; however, I can't open movie files contained in emails or in my Safari Browser--even ones labeled as QT files. I am running Quick Time 7.0.4 on my 10.3.9 eMac. This is a recent problem, as I didn't have this difficulty until the last month or so. I had unchecked the "Open Safe Files" box in Safari's preferences some time ago as a precaution against a virus/worm, but rechecked it after the last one or two Security Updates. What else should I do to resume opening movie files? QT Player runs just fine with movie trailers, etc, but not in mails or the browser.
eMac, iBook Mac OS X (10.3.9) 1 Ghz G4, 768 mb ram

Under the Safari Help menu choose "Installed Plug-ins". This will confirm your QuickTime install.
Under Safari Preferences/Security make sure you've got plug-ins enabled.
Try dragging the email attachment to the Desktop and see if it plays from there.

Can't open movie files

I downloaded windows media for mac and I still can't open movie files. When I click open a error window pops up saying "the file is not a movie file." That's crap I can open the files on my pc but not on my mac. By the way the files are on a external hard drive western digital my book. Is there some way I can convert the files to play on quicktime? Any kind of ideas would be helpful.

Can't open WMV files in Quicktime since Snow Lep upgrade.....

I Can't open WMV files in Quicktime since Snow Leopard upgrade
I get an error message saying 'Quicktime player must be installed to run this application'
This is happening on both of my macs
Any help appreciated

I had this problem. Double clicking the WMV file produced the message you had. However, if I open by dragging the WMV file onto the QuickTime X icon in the dock it did indeed open.
I then looked at the WMV's Get Info window and found that it was set to open in WMV Player by default. Obviously I do not have WMV Player installed. The drop down menu on this setting did have QT Player as the other option. When I changed the option to QT Player as default the "Change All" button became active. Previously it had been greyed out. Things have been OK since, but I have not tried it on any new WMV files.

Can't open mov files on my ipad

Since one of the last IOS updates, I can't open Mov files sent from my own IPhone via email.
I have had a new ipad swapped under warranty, and have reloaded all software from scratch.
When I get the email with the video file. The file is an attachment, I click the file, it downloads, then when I click it to view the video I get a white screen with the file name in the middle and the words quick time movie. And nothing happens

You should download VLC and try viewing the .mov file with it - for troubleshooting.

Try to open mov file with quicktime, says can't open pdf files.

Hi to everyone,
Suddenly I try to open a mov, any mov file, with quicktime 10.4 and some times opens the finder and nothing more, some times says that it cannot open one pdf document ( a document I actually have but never try to open with QT). some times QT says it canot open some png or jpg file.
But I double click mov files. And the incoherence is permanent, I mean that for the same movie file says it can't open the same pdf file, and in other file the same png, or the same jpg.. it depends on the mov file I try to open. Like if somewhere, somme kind of cache, adresse or reference is wrong.
this is the text of one of those messages when I double click a mov file:
"The document “phoenixRoomfillerB_v001_0104.jpg” could not be opened. QuickTime Player cannot open files in the “JPEG image” format."
And if I try again and again, at some point QT open only the finder window.
The weird thing is that on the finder window i can see the preview and play the preview. and the same mov files play well with VLC. And if I copy the mov file to my desktop it plays well unless QT start to open only the finder window, if that happens it does not work anymore with any file.
The files are on an external drive with 3 partitions.
And I make all the possible cleaning that I can:
I am the administrator of the imac and I am the only one to use it.
I am the owner of the volume
I use disk utility to check and everything is ok
I use onyx to clean as much as possible, cache, boot, volume structure, smart status, home folder permissions, kernel, extensions, QT components, etc. and everything works fine.

thanx.

Try QT v7.x which is located inside your Utility folder.

Can't upload .mov files to iTunes anymore

Hi! I don't know if this just started when I upgraded to Lion and did all of the recent updates to iTunes, and added iCloud, etc, but suddenly I can't drag .mov files into iTunes like I used to be able to do. I can't add them with the Add To Library menu either. Because of this I can't put them on my iPad. Is anyone else having this problem? Is there a fix? TIA!

Actually, I can't open anything in quicktime anymore. I've tried opening avis, mov, mp4 and m4a files... all give the same error message and number. I've reinstalled both qt and itunes but no luck.

Can't open .wmv files in Quicktime after archive and reinstall of OS

After recently archiving/reinstalling OS, I can no longer open .wmv files in Quicktime. "The movie could not be opened". "The file is not a movie file" is the error. This applies to newly downloaded as well as previously downloaded and played files. Qtime version is 7.6.4. Changing extension to .mov doesn't work. Any assistance appreciated.

Reinstall Flip4Mac.

Can't open avi files in quicktime 7.5

When I try to open avi files with quicktime .5 i am told that Quicktime needs soe extra files and am taken to the quicktime page on appl.com What files do i need? Any suggestions welcome!

'AVI' is a container which can house a variety of codecs.
These are the downloads and the settings you need in order to view/hear pretty much everything that the net can throw at you: The setup described below has proved repeatedly successful on both PPC and Intel macs, but nothing in life carries a guarantee!
It is known to work in the great majority of cases with Safari 3.0.4, 3.1, 3.1.1, QT 7.3, 7.4.x and 7.5 and OS 10.4.11.
Assuming you already run Tiger versions OS 10.4.11 and have Quicktime 7.2 or above, and are using Safari 2 or 3, download and install (or re-install even if you already had them) the latest versions, suitable for your flavor of Mac, of:
RealPlayer 11 (which is no longer in beta) for Mac from (you may need a different site for the US):
http://uk.real.com/player/mac/
Flip4Mac WMV Player from http://www.microsoft.com/windows/windowsmedia/player/wmcomponents.mspx (Windows Media Player for the Mac is no longer supported, even by Microsoft)
Perian from http://perian.org/
You should read this support page http://perian.org/#support in case you need to delete older codecs.
Adobe FlashPlayer should first be uninstalled using the appropriate uninstaller available here: http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_14157&sliceId=2 and then the latest version obtained from here: http://www.adobe.com/shockwave/download/download.cgi?P1ProdVersion=ShockwaveFlash and installed.
(You can check here: http://www.adobe.com/products/flash/about/ to see which version you should install for your Mac and OS, but please see my footnote if you are running Leopard.)
In earlier versions than QT 7.1.3 in Quicktime Preferences, under advanced, UNcheck Enable Flash, and under Mime settings/Miscellananeous only check Quicktime HTML (QHTM).
You should also ensure, if you are running Tiger 10.4.11, that you have downloaded and installed all the correct version for your Mac of Security Updates up to and including 2008-003. (N.B. Security Updates require both a restart and a permission repair.)
In Macintosh HD/Library/Quicktime/ delete any files relating to DivX (Perian already has them). However it should be noted that Perian is not an internet plugin and will not play DivX files imbedded on a website. For that you will need the DivX Player browser plugin available from http://www.divx.com/divx/mac/
Now go to Safari Preferences/Security, and tick the boxes under Web Content (all 4 of them) to enable Java.
Lastly open Audio Midi Setup (which you will find in the Utilities Folder of your Applications Folder) and click on Audio Devices. Make sure that both Audio Input and Audio Output, under Format, are set to 44100 Hz, and that you have selected 'Built in Audio'.
Important: Now repair permissions and restart.
You should also consider having the free VLC Player from http://www.videolan.org/ in your armory, as this plays almost anything that DVD Player might not.
There is an additional 'fix' you could try if you are having problems with Flash and Quicktime, depending on which type of Mac you have:
On Intel Macs, make sure that you are not running Safari in Rosetta. You can check this, and change it, in the Get Info window.
On PPC Macs, go to the Hard Disk/Library/Internet Plug-Ins folder, and drag the file 'QuickTime Plugin.webplugin' to the desktop. Quit and restart Safari. If things have improved you can trash that file. If they haven't put it back, as the lack of this plug-in can cause QT content in some widgets to cease functioning.
And now there is an additional kid on the block: SilverLight. Microsoft has created their own version of what a replacement for Flash should be. You can read more about it here:
http://silverlight.net/
So, if you go to any sites that have been designed for this new Silverlight stuff, you can download the plug-in from here (but make certain that you are downloading SilverLight v.1.0 for OS X (10.4.8 upwards):
http://silverlight.net/GetStarted/
FOOTNOTE
If you are running Leopard:
Some users have mentioned that the latest Flash Player (v.9.0.115.0) conflicts with Leopard, and that they have needed to revert to v. 9.0.47. This can be downloaded from here:
http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_14266&sliceId=1

Can't open WMV files in Quicktime. How can I reinstall Quicktime?

For some reason I am unable to open WMV files in Quicktime even though I have Flip4Mac Player Pro (WMV files played fine in Quicktime until recently).
ANY help would be GREATLY appreciated!

Quicktime X is a great little piece of software. However, Quicktime X is very finicky on which codec/file format it can decode/play.
Luckily, there are DOZENS of alternative video/media players and extensions available for the Mac. Some of them are even FREE. Some of the better FREE ones include...
PERIAN (quicktime extension)
http://www.macupdate.com/app/mac/22923/perian
QUICKTIME 7.6.6
http://support.apple.com/kb/DL923
VLC Media Player
http://www.macupdate.com/app/mac/5758/vlc-media-player
NICEPLAYER
http://www.macupdate.com/app/mac/15136/niceplayer
... And if none of those work, there is a possibility that, that video file may be corrupted.

Can't view .mov file with quicktime

Hello. I need help viewing a .mov file with Quicktime 7.5. It was recorded on a Canon Vixia HV30 camcorder and given to me on a dvd. But when I try to view the .mov file with Quicktime, I can hear the audio but the screen is black. Sometimes, it asks me to continue to the following link:
http://www.apple.com/quicktime/resources/components.html?os=Windows&ctype=696d64 63&csubtype=69636f64
I'm not that computer savvy - what is wrong? Any advice would be greatly appreciated. Thanks in advance!

Sorry. My "then" (above) should have been "they".
They sent you a data DV containing the "source" from the camera and the HDV codec isn't available on your PC so you can't view the file.
Ask the authors to convert the file using H.264 Video codec (or others) so your Windows version of QuickTime can play the file.

Logic X can't open .mov files?

Logic Pro X won't allow me to open .mov files, whereas Logic 9 had no problem. Is Logic 9 still better for "Music to Film" projects?

Hi, when Garageband 3 (GB07) came out, the same thing happened but they released a patch/update shortly after. Seeing as how iLife '08 just came out, I'd say just sit tight for a week or so and they're bound to come out with the update.

Can't open .mov files for iMovie editing; can't even view in QuickTime, etc

Our band recently had a videographer record our performance using two panasonic hd cameras: AG-HVX200 and HPX170. Both were set to hd 720 X (?) at 30 fps.
All files were saved as .mov files.
We can't see them at all. We were told that they were designed to be opened in Final Cut Pro (which we told him not to do).
We do have Final Cut Express, but neither FCE nor iM allows us to select the files ("grey'ed" out).
Can someone please help us understand how to open these files? Do we need a specific codec?
Thanks much.

I am no expert on DVC Pro HD, but here is what I found out.
HD compression format by Panasonic.
Similar compression type to DV 25 but uses a higher bit rate up to 100 Mbit/sec, depending on
the specific HD format being recorded. Highly popular format because of its lowe r bit rates, and
incredible resolution considering how highly compressed the format is.
This format is very popular as an acquisition format used with Panasonic's Varic am camera as well>as several Panasonic cameras that record to P2 card systems. A lso used heavily to convert higher->end HD formats into a high quality offline e diting format. Uses component recording, DCT
compression at approx. 7:1 (intraframe), 4:2:2 color sampling, 8->bit depth and up to 8 audio channels.
1080 formats record at 1280x1080, 720 formats record at 960x720. At 1080p, frame rates include>23.98, 24, 25 fps. At 1080i, frame rates include 25, 29.97, 30 fp s. At 720p, frame rates include
23.98, 24, 25, 29.97, 30, 59.94, 60 fps.

I agree that you want AIC not DV. AIC is a 4:2:0 codec so you will lose some quality, but it is your best option without buying FCP.

Can't open movie file in idvd

I made a slideshow in iphoto and exported it as a Quicktime movie. Then put it into the Movie folder so I could access it from idvd. But when I open idvd and try to open the file to work with it it is grayed out. And the existing file that I was working on before is grayed out. Anybody have ideas on why I am unable to open these in idvd so I can create theopening and burn to a dvd disk?

This frequently helps solve some problems. Quit iDVD. Search for the file named com.apple.iDVD.plist and trash it. (A new one will be created next launch of iDVD.) Or look in: User/Library/Preferences. This may solve project loading errors too. Restart and use Disk Utility to Repair Permissions.
You'll need to reset some Preferences.

Opening MOV files in QuickTime?

In iPhoto 09, when I double clicked on a video it would automatically open in QuickTime X, where I could edit it and share it to iTunes. In iPhoto 11, when I double click the video it opens up a little editing window within iPhoto, which is cute and all, but totally removes the easy link with QuickTime. Am I missing something? Is there no longer a way to get a file in iPhoto to open in QuickTime? Or, if not, is there a way to export directly from iPhoto to iTunes?

Just noticed this behavior too. I can't get videos I've imported into iPhoto to open externally in quicktime, and there is no longer an option to right-click and "show in Finder." I guess they're really trying to force us to use iMovie, but... would still be nice to have direct access to the video file from within iPhoto.
Anyway, here are two workaround that I believe I've found.
1) select the video and go to File > Reveal in Finder > Original File. This will open up Finder and go to the .MOV file, that you can then open in quicktime from the Finder
2) from iPhoto, drag and drop the video onto your desktop or into another folder in the Finder, and it will create a copy of the video file for you that you can open in Quicktime
