Quicktime not opening .avi files

After I've upgraded to Lion, QuickTime stopped playing .avi movies.
I've Perian codec installed and I've tried to disable it and both with it enabled or disabled QuickTime does not work.
Moreover, I've another problem: after having selected the option "open this file always with VLC" the system is still not working properly since it keeps opening .avi videos with QT.
Any suggestions?

Hi,
Remove Perian and restart.
Remove FlipFor Mac and restart (you are ?).
Install Perian and restart.
In Perian prefs plane : "desable" Load external subtitle
Work for me ! Good Luck.
Latest Version 2.3.8.1 not support OSX Lion
Intel or PowerPC G4 & G5
Mac OS X 10.4–10.6*
Note: Support for Mac OS X 10.7 Lion coming soon
QuickTime 7 or later
Note: QuickTime X does not support conversion using third-party plug-ins. For Snow Leopard and Lion users, , we recommend installing QuickTime 7.6.6.

Quicktime not opening AVI files in Lion.

I just installed OS X Lion but when I try to open any AVI video with Quicktime that reads "The Document <filename> could not be opened. A required codec is not available." I clicked the "Tell Me More" button and I redownloaded the DIVX codec but my files still don't open with quicktime. Is it possible that my codec is not compatible with Quicktime for Lion? But then again the Quicktime application is still the same, it hasn't been updated since Snow Leopard. Is anyone else encountering this?

divx might interfere with perian because perian already covers divx and xvid. Only one solution, not both..
simply uninstall every 3rd party codecs you have installed and go with just one if there are more then one to choose from.
Perian and WMV ( flip4mac ) is all I have on Lion and it plays everything, even downloaded youtube videos ( flvs ), the videos my Samsung mobile phone makes and the strange encoded avis that my sister sends me via email from her vista machine.

QT does not open AVI file

hello,
I have installed Perian but with Mountain Lion QT does not open AVI file (no audio and no video)
do you have any suggestion?

I am using QT pre-installed in Mountain (should be X)
QT X can only play files using codecs it is programmed to expect to be used in the loaded file container/with the loaded file's stated extension. For example, QT X will not play a "muxed" MPEG-2/AC3 file with an MOV or VOB file extension but will usually play the file if the extension is changed to TS, MPG, or MPEG. On the other hand, the QT 7 Player tends to look at the internal header information and select a codec based on what the file says it needs for the actual playback. Thus, the QT 7 Player may frequently play files that the QT X Player does not play.
Besides supporting the the AVI file container, your QT system must also be configured to support the actual audio and video codecs contained in the AVI file and not have a "conflict" problem. For instance, Motion JPEG support for QT was dropped with the release of Lion. AVI files containing MJPEG video thay plays correctly under Snow Leopard will no longer play under Lion or Mountain Lion with additional support. In this case, Perian still provides such support. It also still provides support for DIVX, XVID, 3IVX, and similar third-party codecs commonly found in AVI containers. However, Perian support for such files can become conflicted if you have also installed the actual third-party codecs along with Perian and the different codecs fight over which is to be used for playback. This is why it is important to know the actual codecs used to create files using generic file containers like AVI and MOV and the codec components actually installed on your system, as well as, their potential for creating conflicts.
As to the actual playback of files, there are basically only three options (as indicated by the URL provided above:
1) You can conform the file and/or your system codec component configuration to play your files using a QT player app if possible,
2) You can use an alternative media player app the contains "native" support for the file containera and/or codecs used to create the files, or
3) You can convert the file to a compression format and file container that that is already natively supported by QT-based applications.
Since do not seem to know or are unwilling to identify the specific codecs causing a problem here, the only workflows left to you would be to try playing the file in an alternative media player which contains its own built-in codec support (e.g., VLC) or convert the files to something your current QT system configuration can handle (e.g., use a converter with built-in codec support like HandBrake).

HT3775 how do you extend quicktime to open avi files?

I can't open AVI files, says I'm missing a codec. Using a Macbood Pro with Retina display. Are the files just corrupt?

No; there isn't a codec installed to play those specific AVIs, and the required codec may not exist for Mac OS X. Opening them in the free MPEG Streamclip may reveal exactly what is needed.

Quicktime not playing .avi file!

I have been trying to figure out why it doesn't play for a day now. The thing is, it only doesn't play this .avi file, others I have can play it. It says it needs another component to play it and directs me to the extra quicktime downloads page, but I don't know which one I need. I tried downloading the XviD component, but now it says "Movie cannot be opened. Mac OS Error -1." I need help!

I just solved this issue on my machine. Something in the Perian bundle also conflicts with Intel core MacBooks. I finally resolved the issue and avoided the white screen by removing ALL 3rd party QT plugins (including Perian) and restarted. I was then able to view the AVI files and avoid the white screen. When I added back Perian, I could again not see the files. So, the solve is remove ALL QT 3rd party plugins. I suppose you can add Perian back after you have used the files you require, but be aware there is still an Intel conflict within Perian for certain AVI files.

NEW - Quicktime not opening .mp4 files

I posted this in another topic, but want it to be seen.
I am having a similar problem. .mp4s are not playing. Used Handbrake to create an .mp4 file. It plays fine on every system but the one I need it to play on. Quicktime 7 won't play any video, just a white screen like it is missing a codec. I haven't had this problem before, and nothing has been recently installed that would effect Quicktime. Is there an easy way to reinstall the codecs? I've reinstalled Quicktime several times with no effect, recreated the .mp4 file several times, everything else plays fine. The .mp4 plays in Compressor, iTunes, and, oddly enough, Full Screen mode in QT player, but not in the regular mode. Any ideas?

These are the downloads and the settings you need in order to view/hear pretty much everything:
Assuming you already run OS 10.4.9 or above and have Quicktime 7.2, 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 from http://uk.real.com/player/
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/
Adobe FlashPlayer from http://www.adobe.com/shockwave/download/download.cgi?P1ProdVersion=ShockwaveFlash
In Quicktime Preferences, under advanced, UNcheck Enable Flash, and under Mime settings/Miscellananeous only check Quicktime HTML (QHTM).
In Macintosh HD/Library/Quicktime/ delete any files relating to DivX (Perian already has them).
Now repair permissions and restart.
The world should now be your oyster!
You should also have the free VLC Player from http://www.videolan.org/ in your armory, as this plays almost anything that DVD Player might not.

Quicktime doesn't open AVI file with Perian installed

I have installed Perian but Quicktime X doesn't open AVI files for a week. I have repaired permissions. But Quicktime only plays the AVI file if I reboot the Mac. VLC always plays the file. The AVI codec is XVID. Quicktime doesn't play other formats such as FLV. I have deleted .plist files, com.apple.QuickTimePlayerX.plist. I have found other files(com.apple.QuickTimePlayerX.plist.0GH3f31, com.apple.QuickTimePlayerX.plist.0h9MBzV...) that I deleted also. Any idea? Thanks

And now ... surprisingly I view AVI files in Quicktime without Perian.
QT has very limited AVI support (file type and a few older codecs) built in. Most common codecs use by Windows users, however, require the additional support provided by Perian. If the AVI files are now playing in QT without Perian, then simply check the Inspector, Properties, or Info window to see which codecs are in your AVI file and you should be able to tell if they are among those supported "natively" by QT. Also note that this regaining of the ability to play your files may indicate a component conflict of some sort may have existed previously.

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

Hmm . . . comes with a Utility MPEG2 Component ML app with no explanation of what it's for?
The utility app is an "assistant PKG installer." It allows Lion and Mountain Lion users to install the older QT MPEG-2 Playback Component installer PKG file which is not allowed to run on its own under Lion or Mountain Lion since these operating systems already have a QT X only MPEG-2 component embedded in the QT embedded structure. Without this utility you would have to either copy the component from an older system to your Lion or Mountain Lion system, use Pacifist for installation, or manually open the PKG contents and transfer the component to the appropriate component folder.
As to your "discussion" regarding the playback of AVI file types, there are really only two strategies here:
1) You can add component support so that QT can play the files natively or
2) You can convert the file contents to compression formats that are natively compatible with the unmodified QT component configuration.
Each user should decide for his or her own self which approach best suits their needs for a particular source file. In most cases, conforming the system's codec component configuration to play the source file directly results in higher video quality since no transcoding takes place but this strategy will not work if a codec which is required is not available for the user's operating system. On the other hand, converter utilities tend to support more built-in codecs and are easier to use since the user does not have to concern him or herself with the nature of the particular source compression formats but at the risk of some potential loss in visual quality. As to what converter to use, once again this is a matter of personal choice. In the case of commercial converters like iSkysoft, the codecs are built in while MPEG Streamclip accesses the host operating system's QT codec component configuration. I personally prefer the free HandBrake app for AVI, MKV, TS, MTS, and M2TS conversions since it has an exceptionally full-featured X.264 GUI with some user options that 97% of users are likely to never use.

Quicktime Will Not Open Caption Files??

I tried to locate this specific issue in the dicussion forums, but did not find sometihng similar or an answer. My apolgies in advance if I overlooked a similar post.
I have videos that I have captioned that will not open correctly on other computers (in QT), besides my own. I have added captions as a text track and made adjustments to their positioning on the screen. When others open the QT files from another computer, you can either just see the text track and the movie is a white box, or QT will simply not open the file stating this is not in a format that QT understands.
I noticed there is additional codecs listed with these problematic files, specifically VP6F, MPEG Layer 3, Text codecs.
My question what is the best way for me to remove or change the codec so anyone with QT can view? I have a workaround where I place the captioned QT into Screenflow and re-export, which removes the text codec and will work fine on other computers. I just want to see if there is something I can do in QT/QT Pro to avoid this workaround.
Thank you in advance.

Your files are MPEG-2 and you need additional software to view them in QuickTime:
http://apple.com/quicktime/mpeg2
and a different application than iMovie to convert the audio portion:

After recent QuickTime updates fcp and QuickTime will not open .mov files captured on my FS-H200. Iran

After recent QuickTime updates fcp and QuickTime will not open .mov files captured on my FS-H200. I put this onthe quick time thread and they sent me here.

and NEVER do a software update unless you've got a clone of your startup drive so you can restore your system to it's working state if something goes wrong.

Transferring/opening AVI files off camcorder. it wont open! help! not playable?

I bought a Toshiba camcorder a bit ago and this is my first time transfering the videos to my computer. It won't open/play because it says quicktime doesnt play AVI files. what do I do?

Ok, I'm downloading it right now. hopefully that works. Do you know if AVI files are editable in imovie or final cut express? or do I have to convert them to something else? If yes, how do I do that?
