Quicktime won't play my .mov files since I upgraded to Mavericks.

Quicktime won't play my .mov files, even those from an iPhone, since I installed Mavericks. "Tell Me More" doesn't tell me anything about a solution. Any suggestions?

What do I do?
Frankly, if you have deleted the original movie clips from your camera/camcorder and iPhoto, then it sounds as if you are up the proverbial creek without a paddle and there is nothing further that you can do.
Some facts:
For some reason, the movieclips are awful small (13-30 KB).
640 x 480
Codecs: H.264, AAC
While these facts are of little value without file duration information, as you yourself have already noted, the file sizes quoted are extremely small. A typical VGA H.264/AAC file of reasonable quality would normally have a combined total data rate in the 700 to 1,700 Kbps range depending on specific settings, profile, and level of the encoding software and could be even higher or lower depending on the quality levels required. Therefore, it is reasonable to assume that files in the 13 to 30 KB range only contain 104 to 240 Kbs and either have durations measured in fractions of seconds or do not actually contain enough data to be played. (E.g., the video data may be missing or the file is corrupted.) Thus, it is most likely that something was wrong with the workflow used to "export" your files to the external drive and when you ignored the fact that the files were not playing correctly, you closed the door on anything that you could do when you deleted the source files. (I.e., the normal workflow here is to copy the entire iPhoto library to the external drive, switch libraries, confirm the new library is working properly and only then delete the boot drive copy of the iPhoto library.)
OBS: When I try to convert the files into something else (AVI, MP4 whatever) either it comes with an error, nothing happens or the converted file wont open. This happens with various convert-programs.
If the data in the files is missing, then there is nothing to be converted by any application.

Quicktime won't play my movies, just plays audio

I have some movies downloaded that were .avi files when i got them, I used Divx Doctor to convert them to .mov files. Now, they play fine on my iBook G4, but on my new iMac all I can get is the audio. The movie info says the video is 3ivx 4.5.1 and I have the 3ivx codec installed on my iMac but it still won't play. In fact I have all the same codecs on the iMac that I have on my iBook. Any help would be greatly appreciated.

Try playing it on the iMac under Rosetta. Believe 3ivX v4.5.1 is for PPC Macs only.

Quicktime won't play HDV .mov

I upgraded to Lion, and noticed that Final Cut Pro was not playing my HDV .mov clips off of an external drive in the timeline.
Upon closer inspection, Quicktime also couldn't play these HDV clips either. Quicktime X said "The document ... could not be opened. This media may be damaged." Quicktime Player 7 (Pro) says "The movie could not be opened. An invalid public movie atom was found in the movie."
I then take this same external drive to a Snow Leopard installation, with FCP on it, and all clips work fine, and can be opened in both Quicktime X and Quicktime Player 7 (Pro).
I can also open these files in VLC in Lion without an issue, so it seems that maybe it's a Quicktime codec issue. I look in /Library/Quicktime/ and the AppleHDVCodec.component is there.

Thanks for your help with this, it is very kind of you.
As I understand it, a flattened Quicktime file is one where all of the information of the video and audio are interleaved in the data track. In a non-flattened file, this same data can be spread across a resource fork and a data fork, and can cause issues with certain applications. The files my Direct to Edit (DTE) machine makes are not flat. I think I can make my DTE create a different filetype of footage that'll work properly in Lion and FCPX, but my hours and hours of existing footage that is not flat will have issues.
Before OS X, I remember having issues sharing Quicktime files with Windows users; even if they were using Quicktime. The simple fix was always to flatten the file (usually just opening the file in Quicktime and then re-saving the same file--not re-encoding the file to a different codec or anything, just re-saving it), and the file would then be flattened and work in Windows. I've never had any issues with non-flattened Quicktime files in OS X until I downloaded FCPX on a Snow Leopard machine to test it out. I tried to import the media that works just fine in Quicktime and FCP7 into FCPX and it said it was an unsupported media file. Flattening that same file made it work just fine in FCPX.
It appears to have the same result in Lion--Quicktime suddenly can't read non-flattened files. I wonder if another good test of this would be to use iTunes in Lion. Usually, if you have a movie file in iTunes and add metadata or change metadata through iTunes on that file, the file is not flat. I wonder if Lion would then not be able to be read it?

IPhoto slideshows will no longer play songs from iTunes since I upgraded to Mavericks. In fact trying to use a song from iTunes crashes iPhoto. Any suggestions?

Having a lot of problems with iPhoto since upgrading to Mavericks. Wondering if there's not enough memory in my version (I was unable to update iMovie because my system is incompatible with the new version.) A slideshow will play but silently even though there appears to be a song from iTunes attached. Two songs where I've had this problem were not purchased from iTunes but downloaded from personal CDs. Very frustrating as I simply cannot figure it out. And getting direct help from Apple either via Chat or Phone has become near impossible as you try to wade through the roadblocks of links upon links. I tried to create a new slideshow and pull in songs but the same thing happened. The aforementioned songs play OK on my iPad just not on myiMac - it's a 2.4 GHz Intel Core 2 Duo, so aging not well perhaps! Any ideas welcome.

OK, answering my own question..well, via Arleen 259 and Old Toad apparently courtesy of keysandfood! (Copy of Old Toad post below. Thanks to all...IT WORKED!
In iTunes go File -> Library -> Organise Library -> Reorganise Library.
Then quit and restart iPhoto.

HT204382 quicktime won't play a .avi file?

I donwlaoded a movie and its a .avi and i am getting an error post "converting" where it says
QuickTime player can't open
Help please

Hey agrantapple,
Thanks for the question. After reviewing your post, it sounds like there is trouble with a specific codec. I would recommend that you read this article, it may be able to help you resolve or isolate the issue.

I recently purchased QuickTime 7 Pro to convert avi files to mov files for editing on Imovie. However, QuickTime won't play the files. How can I get them to play and how can I convert them to mov files?

Both the AVI and the MOV file extensions refer to the file container and not the compressed data the file contains. Both are generic file containers in that each may contain any valid combination of audio and/or video data that is compatible with the codec component configuration of the system on which the file was created. On the other hand, whether a file is playback compatible, conversion compatible, and/or edit compatible depends on the data actually contained in the file container. So, you are basically dealing with two separate issues here—the container and what is inside it.
Basically, if you want to make your files ediit compatible with iMovie, you must change your file container to one that is acceptable to iMovie and convert the data to edit compatible audio and/or video compression formats as may be necessary. The best approach is to determine what codecs were actually used to create the original AVI files and add them to your system if possible. In most cases a codec package like Perian can be added to your system's codec component configuration to may the AVI file playable. Once they are playable, in the QT 7 app then they can be chnged or converted to file types and compression formats that can be edited in iMovie. (While Perian handles most codecs commonly used to create AVI files, it does not handle all possibilities and, while the Perian codec package still works under cureent Mac OS versions, its development group has decided to drop further development/support of the package.)
Background: AVI is a file container originally developed by Microsoft back in 1992 but for which official support was discontinued about 11 years. Despite its limitations, Windows users still tend to use this file based on its open source ease of use and generic nature, thus, making its use so popular that most users are unwilling to switch to more modern but less generic file types. Since some AVI legacy compression formats have never been transcoded for the Mac or use beyond OS 9 or OS X PPC platforms, it is often important to know what specific compression formats are contained in the AVI file to know which codecs to add to your system and which not to add in order to avoid possible codec conflicts.
You can use many different converters to convert AVI files to iMovie edit compatible files. Most third-party apps contain their own buit-in codecs which do not relay on the Mac codec component configuration. Free ones, like HandBrake, usually have limited conversion capabilities while those that have more varied outputs are usually commercial in nature and will cost you additional cash. QT 7 Pro or the free MPEG Streamclip app allow you to access you own system's component configuration and use any available codec component like DV, AIC, MPEG-4, H.264, Photo JPEG, etc.—all of which are iMovie compatible for editing purposes—but only after making the AVI file QT 7 player compatible.
In order to determine what compression formats wewre used in your AVI files you can
1) Try checking the Finder "Info" window,
2) Use the "Inspector", "Media Info", or "Properties" window of any player app that will open the file, or
3) Use a general media utility app like "MediaInfo" to read the file characteristics.

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.

Since I upgraded to Mavericks I cannot play .AVI files in Aperture

Hi, I have about 1 Tera of .AVI videos as referenced files to Aperture libraries that I have spent long time organizing, tagging, and keywording... Since I upgraded to Mavericks I cannot play these videos any longer. I can play them with VLC or DivX but not within Aperture. Is there any way to ask Aperture to use VLC to play the videos? Or to get Quicktime to play them within Aperture? I assume I am not the only one with this problem but haven't found any way to solve it.
Thanks a lot for any hint!

Hi, I have about 1 Tera of .AVI videos as referenced files to Aperture libraries that I have spent long time organizing, tagging, and keywording..
It is probably not a question of avi or mov. AVI is just a container for media with a variaty of codecs. It will depend on the codecs you installed, if Aperture will be able to show these.
What is your Aperture version? Have you upgraded to Aperture 3.5.1? My Aperture version has no problems to show my AVIs. I installed Perian 1.2.3 to have more codecs.

HT3775 I have Mac OS X v10.6.8 and it won't play an mpg file. Any idea why not?

I have Mac OS X v10.6.8 and it won't play an mpg file. Any idea why not? I get the message that The document “M2U00002.MPG” could not be opened. The movie is not in a format that QuickTime Player understands. You may need to install additional software to open this type of file. But when I go to the help page it says that Quick TIme will play MPEG. Any help would be appreciated a lot. Thanks!

Try VideoLAN media player

HT3523 I can play an .mov file but cannot open it to move it to another drive/disc/etc. When we try to open it, we get a message that says "The movie file for "beanmine.mov" cannot be found. Without this file, the movie cannot play properly."

We can play a .mov file (a full-length film created in final cut pro) but cannot actually open it in QuickTime. We get the error message saying that a file is missing, and the movie can't play properly without the file. The thing is, we can play the film, we just can't open it to move it to another drive. Help?
Also, can the lost file (which was deleted) be recovered from a Mac HD or an external hard drive?

Sounds like you created a "Reference" file here. I.e., a "Reference" file is a file that tells the player how to play the data contained in a "Resource" file. When you try to open the "Reference" file in the QT Player app, the first thing the player does is check to see if the "Resource" data file is is still available where it is supposed to be. (I.e., moving/deleting the resource file or moving reference file without moving the resource file to maintain the relative path between the two will generate the error message you mentioned.)
Also, can the lost file (which was deleted) be recovered from a Mac HD or an external hard drive?
That depends. Deleting a file does not actually erase the data immediately. Instead, the operating system just tells the system directory that the space containing the movie data is available for reuse if/when needed. As time passes, the chance that some of the data sectors will be re-written by other data continuously increases. To restore the file normally requires use of a special utility that both locates and restores all of the linked sectors containing the "deleted" movie data in their correct order. Other methods of restoring files would depend on the software you routinely have active on your system. For instance, do you use "TimeMachine?" or orther software that automatically backs up your data periodically? If so, then follow the instructions for your particular application to recover a deleted file.

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.

Playing a .mov file on ipad

Hello,
I cannot open/play a .mov file from my dropbox on my ipad. Message <<file type is not currently supported>>. I made the movie with imovie and it works fine on my computer. I am also capable of using video in the photo center. How come I cannot open it from dropbox? Is there another way to send the video to my ipad and save it there.
thanks!!!

Hi loliza,
If you are having issues opening a .mov file directly from Dropbox, you may be able to sync it to your iPad from iTunes. You can also verify that the file plays directly in iTunes, and/or see if it may be necessary to convert/create an iPad-specific version. You may find the following articles helpful:

Quicktime will not play any video files

When trying to play any compatible video files .mov, .mp4 etc... all I get is a small black box in the upper left corner of the screen. The computer is not frozen I can close the window with the red x. I can open Quicktime and the web stuff opens but opening a video file on the computer causes this. I confirmed the latest version of Quicktime in installed and I have confirmed the video files I'm trying to play work on another computer and the .mp4 file plays in media player on this computer. The video card driver is up to date. I want to play my .mov files from my iphone but can't.

all I get is a small black box in the upper left corner of the screen.
Curious ... I wonder if this is a blown-out display preference?
Could you check something for me please? Create a new user account on the PC with full sdminidtrative rights. Log out of your usual account and log into the new account. Try playing a file in the new account. Does it display properly?
If it works okay in the new account, let's try to get things working in the normal account again with the instructions from the following thread:

Playing AVI movie files??

Help. I have 3 Macs: G4 Flat Panel, Imac G5- which play AVI movie files just fine. Mac Mini (specs below) which does not. Been at it for hours. The two older ones are non-intel, the mini is intel, this is the only difference I can see. I have the same software and plug-ins installed; (quicktime pro, flip for mac, windows media player, divx plug-in, xvid) All of them are running 10.4.11. When I put in a movie encoded in AVI in the mini I get a prompt that says roughly 'additional software plugin might be needed', can't think of anything else to do. Any info appreciated. Thank you.

If anyone else has this problem with an intel based mac here is link that solved my problem.
