Quicktime won't play audio correctly in IE and Firefox

It just get's stuck and seems to have a hard time processing the audio part of the video, and if I move cursor to later in the video it takes forever to load. This problem just started recently and appears in both internet explorer and firefox meaning it shoudln't be the browsers fault. Itunes works fine but apparently quicktime is having the same problem outside of internet applications as well.
I have tried uninstalling it and reinstalling it. I deleted the whole quicktime folder after a few tries and also tried installing a new version. None of these seem to have done the trick. Any help appreciated.

Not sure if all FF versions are the same. In v1.5.0.11:
FF>Preferences>Downloads
Click on the "View & Edit Actions" button.
The next window should show if your browser QT plug-ins are installed.
I do not know how FF v2.x preferences are set up.
If push comes to shove, you may wish to try out Michelle Newcomb's suggestions or the following:
See if repairing permissions & restarting helps. If not..........
Try the following:
Make sure you have the latest versions of Adobe Flash Player Software
QuickTime Preferences > Advanced > MIME Stettings > Miscellaneous.
Deactivate the "Flash Media" option.
This tells the browser not to to display Flash Media and lets the newly installed Adobe software work its magic.
Good luck!

Quicktime won't play audio of .MOV files

Quicktime displays the video portion of .mov files from my digital camera, but the audio sounds like a (very loud) jackhammer, and seems to hang. Ditto with other viewers (irfanview, etc.) that depend on Quicktime.
However, Nero ShowTime plays the same files just fine.
It's as if quicktime didn't fully install codecs, although uninstall/reinstall sequence didn't help, and no messages indicating any problems.
PS... it used to work great (months ago) -- no clue how it was broken.

I'm experiencing the same problem, with the only difference that my qt has no video on one account, and behaves normally in another account. I compared the versions, but the seem to be the same.

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.

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.

Flash won't play audio. Please help!

To anyone who can help,

I'm experiencing the same problem on Snow Leopard 10.6.8. If I go to YouTube, I don't get audio. Other websites are fine (I'm not seeing a pattern on exactly which sites). What I had to do was uninstall Adobe Flash (I used the Adobe Uninstall utility). Now I have audio on YouTube, but now I'm getting a lot of 'missing plugin' messages from other websites. I've opened

IOS 6.0.1 Safari won't play audio files. Error: "Cannot play audio file."

I recently updated my iPad to iOS 6.0.1, now Safari won't play audio files in any format. Error: "Cannot play audio file." Previously, it worked fine. I tried downloading and using GoogleChrome and Opera Mini, and these also won't play audio. What's up??

Solved the problem. It seems that once iOS 6.0.1 installed, it caused all of my browsers to mishandle audio files. When I reset the iPad, that cleared up the problem.
Before upgrading to iOS 6, my browsers would "autoplay" the sound files. After iOS 6, "autoplay" is disabled so you have to manually click play to play them.
Nonetheless, everything is working fine again except for "autoplay," which I can live with.

After the update iTunes keeps crashing and won't play any of my music and keeps restarting my phone.

Thank you!

Well, I hadn't rebooted after the 7.1.1 upgrade, but obviously I had to restart iTunes. After I rebooted my iBook iTunes worked... Maybe the 7.1.1 update should be marked with a must reboot?

So I've downloaded a tv series from iTunes onto my macbook pro, for some reason the episodes on my iTunes won't play at all. no sound and no images. any suggestions and help?

Hi,
As you have match, I suggest that you create a new library by holding ctrl whist launching iTunes. Select create new library. Sign into iTunes Store and activate match. You will now have access to your music and will be able to stream your music.
Options : get a new external drive formatted for mac and either download music from match or copy music from old drive to new one. Alternatively you could reformat old drive and download music from match - I would not be comfortable using this option as it means erasing drive before being able to use with mac.

If it works in Windows Safe mode then you have a problem with other software, possibly security software or a system driver, that is running on your computer.<br />
It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

QuickTime 7 Audio Issue (Won't play audio in certain video clips)

I'm having a problem getting audio to play with clips in QuickTime 7, and it doesn't play at all in iDVD when I drag a clip in to burn a DVD. I'm also having problems getting Final Cut Pro to play audio from time to time. Is this being caused by a recent Apple security update or is there something else going on?

Quicktime Kirk,
I have downloaded another persons inquiry because it is exactly the problem I am having. Here is his post
"I make movies of cells and convert them to quick time and insert them into powerpoint for presentations for conferences. I never had a problem with this until I upgraded to office 2004 and now many (but not all) of my movies won't play. They seem to be there but when I click play they go white as though there is only the first image. I had saved them as cinepak and or jpeg A usually with image J or older ones from the original NIH image and I can't figure out what the problem is. I even upgraded to quicktime pro to resave them as self contained but still they don't work when I insert them. I can play them all with quicktime player and when I make new ones now in image j I save them as video and that seems to work but it would be very difficult to go back and do that with everything. Does anyone know why or how to fix this?"
My additional comments would be I used the Sample_iTunes.mov from QT and it plays like a champ in PPT. My movies are all from 2004. When I save them in the QT 7.1.3 it doesn't seem to make any difference. The older movies insert into PPT as a QT icon with 4 color quadriant. Everything including .swf are now working in QT. Thanks for your help. When I go back to 7.0.3 they work but then I can't play my videos in iTunes unless I do an erase and a reinstall to get rid of the updated iTunes. Thanks

FCO 10.2 won't play audio. Was fine in 10.1.4, projects open fine, the meter shows it playing, made all correct connections in Inspector, but no sound to system?

Since upgrading to FCP 10.2 from 10.1.4, I'm now not able to get sound even though it shows it's playing in the meter. The clip is a .wav 48k, I have highlighted the audio, gone into the Inspector, chosen Audio, in Pan Mode I've chosen Stereo Left/Right and made sure Stereo is selected on the file in the Channel Configuration. Solo does not help nor is skimming available.
All other audio apps are fine including Quicktime.
Also, I triedstarting a new Project and Importing audio, but the same result. Please let me know what I'm missing.
Is there a way to rollback to 10.1.4 to finish this project?
Thank you in advance for your reply.

Thanks Tom- shortly after I posted I read that and the multichannel change in the AudioMidi Setup was indeed the answer!
In reading through the posts, I see you have had answers to many issues so perhaps you help with this :
In 10.1.4, I had used an FX Factory effect for scrolling credits and now it won't play back on 10.2. If I highlight the clip, I have the ability to edit the text, but it won't play- any help is appreciated.

Thanks again, Tom

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.

Clips won't play at correct time

Hi,
So a while ago, iMovie HD was working just fine, but then it started messing up the timing of my project. I am making a slideshow that is 15 minutes long right now and will get longer. I only use still pictures, music, and titles (no Ken Burns or transitions). Now, when the playhead is at the start of a pic, the photo won't play until about 3 seconds later. Sometimes, when the photo is playing at the wrong time, a different picture flashes. Basically, the duration of the pictures is all different, even though i set them all to have a 3 second duration.
I'm very confused why this is happening, because the same problem is happening to all my imovie HD files, not just the one. However, only pictures are delayed, not video clips or title sequences.
How can I fix this?

Hi
OK - I can give it a guess.
• Trash preference file - and/or -
• Repair Permissions
• Free space on start-up hard disk >>10Gb
this takes care about 95% of people with this problem. If it still persists after this
it will be more tricky.
My general list on this
*Not knowing the origin to Your problem - General approach when in trouble is as follows.*
• Free space on internal (start-up) hard disk if it is less than 10Gb should rather have 25Gb
• Delete iMovie pref file
iMovie pref file resides.
Mac Hard Disk (start-up HD)/Users/"Your account"/Library/Preferences
and is named. (one or more of these)
com.apple.iMovie.plist
com.apple.iMovie3.plist
com.apple.iMovie7.plist
com.apple.iMovie8.plist
and find
com.apple.iApps.plist
While iMovie is NOT RUNNING - move this/these file/s out to desk-top.
Now restart iMovie.
• Hard disk is untidy. Repair Permissions, Repair Hard disk (Apple Disc Util tool)
• Garageband-fix. Start it, Play a note and Close it. Re-try (Corrects an audio problem that hinders iMovie)
• Screen must be set to Million-colors
• Turn off Mac and disconnect Mains/Power for 20-30 minutes - will at least re-set FW-port
• Third party plug-ins that doesn't work OK (not relevant for iMovie’08 or 09)
• Problems in iPhoto Library can affect iMovie to crash on start-up. Re-build this first then try to re-start iMovie.
This You do by
_ close iPhoto
_ on start up of iPhoto - Keep {cmd and alt-keys down}
_ now select all five options presented
_ WAIT a long long time
• iMovie updated ?
• QuickTime updated ?
• Mac OS version ?
• Program miss-match. iMovie 4 - will not work under Leopard
• Program miss-match. iMovie 5.0.2, up to Mac OS X.4.11 AND QuickTime 7.4.1 - is OK
• Program miss-match. iMovie 6.0.3 or 6.0.4, Mac OS X.4.11 AND QuickTime 7.4.1 - is OK (will work under Leopard and Snow-Leopard)
• Program miss-match. iMovie’08 v. 7.1.4, Mac OS X.4.11 AND QuickTime 7.5.5 - is OK (will work under Leopard and Snow-Leopard)
• Program miss-match. iMovie’09 v. 8.0.6, Mac OS X.5.8 AND QuickTime 7.6.4 - is OK (will work under Leopard and Snow-Leopard)
From LKN 1935. (in this case = iMovie HD (5), I tried it all, but nothing worked.
Your answer (above) has been helpfull insofar as all the different trials led to the conclusion that
there was something wrong with my iMovie software. I therefore threw everything away and reinstalled
iMovie from the HD. After that the exportation of DV videos (there has not been any problem with HDV videos)
to my Sony camcorders worked properly as it did before.

I run "Cache Out X", clear out all caches and restarts the Mac.

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???
