ITunes won't play .mov QuickTime files anymore

My hard drive crashed two weeks ago and it has been replaced and almost all of the information was salvaged--thank god!
However, now in iTunes when I go to play a movie that previously played in iTunes, it says that the file requires QuickTime and that it is not supported by this version of iTunes.
I have over 9,000 movies in my iTunes MOVIES section that are of various formats (none are flv or avi, as I don't think iTunes has ever played those). I've never had trouble playing mov, mp4, m4v, mpg files before. Is this likely a problem with my reinstall of iTunes or is it that the latest version of iTunes has limited parameters than prior versions?
Thanks for any imput. I'd really like to be able to play all of my movies in iTunes like I could before.
Chad

I'm sorry that I have no solution to offer, but I also have noticed that several video files with the .mov extension that used to play just fine will no longer play in either the current QuickTime Player or in the older QT Pro Player 7. I have no idea what changed.

ITunes won't play movies, Quicktime will

This is very aggravating. My iTunes movies refuse to play in the iTunes player. If I navigate to where the movie file is located, right click it and open it with quicktime, it will play flawlessly.
If I try to play the video in iTunes it will just stick on the first frame, play a couple seconds of audio, then do nothing. I can scrub through the entire movie and the frozen frame will change to where I've scrubbed to, but it will never play.
I've tried complete uninstallation of all apple software as one of the support articles suggested, then reinstalling fresh, to no avail.
I've tried changing the audio from 16 to 24 and used various levels of Hz (44100, 96000, etc) as some people said this was how to fix it but that didn't work.
I've tried disabling Direct3D, and disabling all the hardware acceleration in the quicktime preferences, to no avail.
Can somebody please tell me how to fix this? I am on a very fresh windows 7 install and really have hardly anything installed on this computer. Just google chrome, iTunes, a few steam games, and Skype. I really don't understand what could be causing this issue. I am disappointed that an apple product is requiring more troubleshooting than any windows program I've ever worked with. My iPhone and iPad work flawlessly, it's a shame that iTunes is having such a massive issue (I can't even play the videos I purchase... really?)

Ok so I figured out what was causing the problem and how to fix it.
It turns out that you can't use enhancements on your iTunes audio source. If you go to control panel --> sound --> right click your device on the list --> properties --> enhancements tab, then check "disable all enhancements" your videos should play. You guys may want to add this into the support article about iTunes video playback issues on windows, as it impacted the video playback, but was in the support article for audio troubleshooting.

Final Cut Express HD won't recognize .mov / quicktime files.

I have a MacBook Pro 13-inch with FCE3 installed. I'm using OSX 10.6.6. My camera doesn't put video out through a firewire, only usb, meaning FCE can't recognize it (to the best of my knowledge). So, to get around that, I uploaded the video through iLife '11 and converted all my video into one long .mov/quicktime file. When I try to import the video, I get a "file error" message.
Any tips on how I can get the video form iMovie to FCE? If it means not using quicktime, I'm fine with that, too.
Thanks!

Well, to repsond to Ian, I don't have FCE4. I have FCE3. I'll upgrade eventually, though.
And I have a Cannon FS20. I did what you said in the quicktime player. Here's the format:
"H.264, 960 x 540, Millions Linear PCM, 16 bit little-endian signed integer, 2 channels, 44100 Hz."
The video plays fine in iMovie '11. I even tried the "share with Final Cut" tab in iMovie, but the video still wouldn't work in FCE3.
But I might add that it's not just the video from my camera that doesn't work in FCE3. It's all quicktime video. Even video that worked in FCE3 on my old Powerbook G4 now don't work in the same in FCE3 for my MacBook Pro.

ITunes won't play my music files now

When I open up iTunes, it will no longer play any of the music files in my library. When I click on any song in my library, the file appears in the area at the top of the window where the song-in-play usually appears. However, it does not start; the little diamond does not progress through the song. The iPod however plays everything fine. I have a PC with Windows XP and have been told that it could be my drivers. I am lost as to what I need to do here. Can anyone please help?
Forever grateful for any help,
Greg

Well anything is better than version 7. It was totally unusable.
7.1 is an improvement but songs cut out for me. The dialio thingy shows that it's still playing, just no sound. I pause it and restart, the song continues. Sometimes this will happen three times in a row then not for several minutes. There also seems to be a clicking sound every now and then as well.
Yes I've tried switching it between 24 and 16 bit, no difference.
It's a shame as I really enjoy using itunes. I think Apple should stop using work experience kids to program their windows products. I was considering buying an Apple until this itunes debacle.

Slideshow won't play video(QuickTime file), works fine in Keynote('08), how to fix?

Shows up in the slideshow but video does not start, even though after the time the video would play, the slideshow continues, and even plays the next video OK. The Keynote works perfectly, the problem is only witht the recorded Slideshow, so I can't export a working version. Ideas?

ITunes won't play quicktime videos on Mac anymore.

I'm using 10.7.3
iTunes 10.6
MacBook Pro 2.6Ghz 4GB ram
iTunes won't play my video anymore and it's been a while I'm not sure when it occured if it's after an update to snow leopard or iTunes updates...
When I double click a video I get "This movie requires QuickTime, which is not supported by this version of iTunes." ??
...and cannot convert the option doesn't work I get this other message when trying to convert a version for APPLE TV in advanced menu "None of the selected files were converted because they could not be found."??
But the movies are quicktime movies in my library and the MPEG-4 plays in iTunes but not on APPLE TV.
From all my videos I get one only going through APPLE TV and when I try opening it it says error occured why opening and never works??
It seems APPLE is regularly messing things up in updates to loose people so they have to pay for tech support, I didn't upgrade to iPhoto 11 and cannot import anything anymore into it so my entire library is a dead one ; not a cool way to do business than messing people software so they have to buy newer versions!!!
Any specialists that know how to fix this ??

The 32-bit solution has never, I repeat, never worked for me. I've even done a full reinstall on a clean drive of OSX Lion with a fresh install of iTunes downloading a video of "The Big Bang Theory" that just came out this last thursday and still get the error (just finished the full reinstall to a clean drive now and, no, I didn't do any backup restores.)
The only solution I've found is to remove the video from iTunes, without deleting the file, then import the file back into iTunes.
Switching to 32-bit iTunes to run the file causes iTunes to tell me it needs to open iTunes to play the file then it sits and waits for itself to open until I cancel the process. The video then plays without audio.
I have noticed that I can stream the files to my Apple TV to play even while getting the error trying to play them on the computer I downloaded the files onto.
As a result of this error, I've had to reduce the amount of content I purchase from iTunes. no more buying whole seasons at a time unless I do it at the start of the season. Even then, I'm reconsidering it. The amount of work required to get the files into a playable status on the computer is simply too great on an on-going basis.

TS1859 I have a .mov file that won't play in QuickTime Player, MPEG Streamclip or in FCP but plays in VLC, how can I convert it so I can use it in FCP?

hi
download perian from internet, it'll solve your issue.

Mov files won't play in Quicktime?

Hi,
I have to cut some footage with Final Cut Pro. I used an G5 for that which worked fine. But I have to change to a MacBook Pro with Intel Core2 Duo now, because the G5 is to slow.
Sadly, the footage I have won't play with Quicktime and - of course - neither with Final Cut Pro on the Intel Mac. I just have the sound, but no video. Seems like a codec is missing. but when I download the codec it won't install because it seems to be already installed...
I don't know how the footage was captured, I assume with FCP though... Info says: "Apple Intermediate Codec".
I updated everything except "Compressor" because the update fails.
I use MacOS 10.6.2 with my old FinalCut Pro HD 4.5 (Rosetta). I have Perian installed.
What can I do?

This is a quick time Codec problem... I want nothing to do with FinalCut...
I have a series of videos from my wedding that I want to convert into some other format that can be edited in Premier.
The videos open in quicktime, but only give me audio and no video. VLC will wont even play them saying
"No suitable decoder module:
VLC does not support the audio or video format "icod". Unfortunately there is no way for you to fix this."
Any ways, I opened them up in quicktime and get the properties of the videos
Video track - 27.58MB - Apple Intermediate Codec
Sound track - 531.72KB - Integer (Little Endian)
The file itself is 28MB, so I know the video is still in there somewhere.
If someone could please tell me how to convert these, I would be greatly appreciated. These are the only videos of my wedding, so I really need them to be saved.
Please email me if you might have any suggestions.
Thanks

Quicktime won't play movie files

I upgraded my iMac from 10.5._ to 10.6.4 and now my video files won't play on Quicktime 10 by double-clicking. I have to drag them to the Quicktime icon on the dock. How do I set the iMac to play use Quicktime as a player when I double-click?

brianak welcome to the discussion forums- How about if you highlight your file, then command-i, and in this info panel select *open with* QuickTimePlayer and *change all.*
Hope this helps.

MacBook Pro won't play .mov or .wmv files.

Since "upgrading" to Lion my MacBook Pro won't play .mov or .wmv files, all I get is a black screen and the audio. It's so frustrating!!
I've read many other posts all along the same lines and wherever possible I've tried to follow the advice which has been given but nothing works.    I've updated all the drivers I can and I've even reinstalled Lion, nothing makes a difference.
I'm not really looking for any more advice, all I want is someone from Apple to read these posts, realise there is problem and get working on a fix or update.
I had no problems when running Snow Leopard and it would seem, looking at everyone else's problems, that the common issue is Lion.   Seriously, this is one area where Lion is a backwards step.   It should just work (like most things from Apple), but it doesn't.
Personally I believe there is a problem with Lion but from what I've found out from speaking to friends with other Apple kit, this might be a random issue only affecting some people as some have said they've had no problems while others have had the same issues as me.    One guy reinstalled Lion and it resolved the issue for him, I've not been as lucky.
As I say, I'm not really looking for more advice, simply some sort of update from Apple to fix it.   PLEASE!!!

This is a peer-to-peer user forum. Perhaps you would see more action if you and others would file a formal "Bug" report with Apple QuickTime technical people rather than repeatedly reporting a possible problematic problem which may or may not affect others on a random basis. QUICKTIME PRODUCT FEEDBACK
Since you aren't seeking further advice here is what I have observed. Not being a regular WMV file user, I had to create my own sample file to test—a WMV 9 file containing WMV3 compressed video and WMA2 compressed audio. Since I normally use QT 7 as my primary media player, I also stored the WMV data in its partially decompressed form in an MOV file container to avoid pre-playback delays in "classic" player routines and also provide a secondary playback test of MOV wrapped content. These files play as follows using the Flip4Mac component/player support and uncoded URL uploads:
QT 7.6.6 "Open File" - both files play correctly.
QT 7.6.6 "Open URL" - both files play correctly.
QT X.1 "Open File" - WMV file plays correctly. MOV file plays video without audio.
QT X.1 "Open Location" - WMV file appears to open but plays with "black" screen and no audio. MOV file plays video without audio.
VLC "Open File" - WMV plays correctly. MOV file doesn't open,
VLC "Open URL" - WMV file plays correctly. MOV file appears to open but nothing plays.
MPEG Streamclip "Open File" - both files play correctly.
MPEG Streamclip "Open URL" - both files play correctly.
GarageBand - WMV file will not import but MOV file does.
iTunes - WMV file will not import. MOV file container is accepted but as soon as iTuness sees the compression formats, it aborts import.
Safari - WMV file URL auto-downloads and playes in the QT X.1 Player. The MOV file URL opens and plays in Safari.
As you can see from these results the files do play but are subject to many different constrints based on old/new video technology support, independent QT subsets and/or container trapping constraints. In short, individual user results will depend on presence/absence of component support, actual compression formats, file container, application being used, and how the application is being used. Unfortunately, most users here can't or won't provide the prerequisite information or a sample file for independent examination. This makes it next to impossible to give advice in these matters or categorize the specific nature of the problem.

ITunes won't play audio with mp4 or mov video

I have wasted many frustrating hours now trying to get iTunes to play mp4 and mov videos but can't get any sound. A few months back it was working fine. Tried ALL the suggested fixes like uninstalling, updating and checking all the MIME/File boxes. When I went back to QT 7.5 and played the files independently of iTunes everything was fine. Quicktime 7.6, 7.67 & 7.7.1 do not play the audio independently or under iTunes and of course iTunes won't play video with QT less than 7.7.1. The same mp4 videos uploaded to my iPOD work fine. I currently have iTunes 10.5.3.3 installed on a Windows XP SP3 on an e-machines pc. Ideas please!!

I got this problem as well. Seems as soon as I moved to version 7.6 it stopped playing my video audio. My music plays fine, but my video audio is non-existant. It's not the file itself because I can play off my iPod (though not off my iPod through iTunes) just fine. I've done all the suggestions above and NOTHING has worked. Is there anything else we can find???

I paid for and downloaded a song, but it won't play saying the file could not be found. It says this even when I click on the song IN the itunes store, so I can't even listen to the sample now??

I haven't kept records of the songs I have paid for, and a number of songs have recently been displaying this message, making me search my computer for them. Most I have been able to find, but this one immediately "disappeared" the moment I attempted to play it after downloading...... how do I either get it back or get my money back???

How did you do this move? Unless you know what you are doing you have to move the whole, complete iTunes folder.
iTunes: How to move [or copy] your music to a new computer [or another drive] - http://support.apple.com/kb/HT4527
Quick answer if you use iTunes' default preferences settings: Copy the entire iTunes folder (and in doing so all its subfolders and files) intact to the other drive. Open iTunes and immediately hold down the Option (alt) key (shift on Windows), then guide it to the new location of the library.

Quicktime V7.4 won't play movie rentals

I upgraded to QT 7.4 and now iTunes won't play my movie rentals. It just somes me the movie with no sound. I have even gone so far as to uninstall 7.4 and install 7.1, but then the movie won't play at all, just goes to the iTunes store and then stops, doing nothing. Can anyone help? Much appreciated.
Larry

I was having the same problem but just found a solution for IE. You need to make sure the QuicktimeCheck Class addon is enabled. Tools>Internet Options>Programs>Manage Addons. (Addons currently loaded in Internet Explorer)
I am not sure how this got disabled but enabling it got rid of the "Get the latest Quicktime" message and allowed me to view trailers once again.

Premiere Elements 4 audio won't play on mp4 files, codecs missing/unavailable on .mov files

I dowlnloaded Premiere Elements 4, and when I import mp4 files, the video plays but the audio will not. I've also tried to import .mov files, and an error message pops up that says "Codec missing or unavailable." I downloaded the latest version of Quicktime, but that didn't change anything. The files will play back on the video camera, but I"m having trouble with them on my computer. The audio on the mp4 files plays in Quicktime, but not the video, and vice versa when I import them into Elements. Any suggestions?

Does Quicktime Pro also edit .mov files on a PC?

Premiere Elements 4 pretty much works with tape-based digital video. That would be video from a miniDV or HDV tape-based camcorder. It doesn't handle other formats very well.
If you plan to edit MP4s, you definitely want to upgrade to a more current version of the program. If you can't install a current version of the program, you may need to address issues on your computer (such as an outdated operating system or underpowered hardware configuration).
Short of that, you could buy Quicktime Pro from Apple for $29. It will edit MP4s, even on a PC platform.

Why is Lion so slow? Everything takes 2-3X as long as before and iTunes won't play most of my movies.

Got Lion. Now, opening a movie with Quicktime takes 10 seconds, opening ANY application takes twice as long as before, and iTunes won't play most of my movies that used to play in previous versions of iTunes. I'm frustrated. Even the web is markedly slower with pages taking 5-6 seconds to load up (and they are simple pages sans videos).
What gives? Any solutions? Anyone having similar issues?
The ONLY thing that took less time was Disk Utility...it ran in 4 minutes when it used to take 7--8 minutes.

Lion is much more demanding on memory. It is almost unusable on my computers that have 2 gig of memory. On the macbook air I am typing this from, it is using 1.5 Gig of memory out of 2 gig. Anything like playing a movie is going to be quite compromised. SL used about 400 MB for normal low-demand operations. The memory is soldered on in this laptop, so I am screwed, but it is fairly cheap and easy to add memory to most others. OWC is a good place to look. Max it out. I think your iMac can take 6 GB.
