Quicktime no audio in 10.10 but audio in 10.9

I have an iMac that is running 10.10.2 and I have quicktime 7.7.6 and 7.7.3 as well as the quicktime x that came with the 10.10 OS.
On my macbook that is running mac os x 10.9 I have the same quicktime file. when I open it, it has sound. SO I thought that maybe the file that I have on my 10.10 iMac maybe corrupt. SO I connected to my macbook thru my iMac and transfered it over to my iMac. It downloaded and I clicked on it and what do you know, NO SOUND!! It was a .mov file when I first downloaded it 3 years ago, but I saved it as a .mov file in quicktime and it worked in all os x updates until 10.10. I have VLC, M Player X, Flip for mac, and perian. I just can't get this file to play audio

QuickTime 10 has ended support for "legacy" codecs and that's why they don't play except in QuickTime Player 7.
Use QuickTime Player 7 from this download link:
QuickTime Player 7 for Mac OS X v10.6.3 or later

Strange QuickTime conversion audio problem

QuickTime on my G5 will no longer export Final Cut files properly as H.264 - the video is perfect, but the audio just stops after about 1'30.
This never used to happen. I have tried with FCP container files and with FCP self-contained files, and the problem is the same. It started before the QuickTime upgrade, but even after upgrading, it is still happening.
Yet when I moved the exact same FCP file over to my MacBook Pro, and tried an export with the same settings as I used on the G5, it worked fine.
I can also do this export fine on the G5 with software such as MPEG Streamclip - just not QuickTime.
What on earth could be wrong that QuickTime's audio is failing at 1'30?

I confirmed that it's either a QT 7.2 issue, or OS 10.4.10 issue (guess which I think is more likely :-)).
I moved the iMovie to my wife's macbook, who thankfully usually hits cancel when the software update screen appears so it was still on 7.1.6 and OS 10.4.9. The movie exported fine. Not a great test, since I was changing processor types, iMovie versions, and OS versions, but it did work. Then I upgraded her to 7.2 and 10.4.10 (in retrospect, should have just done 7.2 to only change one thing, oh well), did the exact same export procedure, and the audio was corrupted the exact way that my computer broke it.
So it's in one of those components for sure. I opened a bug, #5345205, for what it's worth. Hopefully they'll be able to replicate somehow and issue a fix. too bad there's no easy way to rollback an update.

Where did the media file come from?
Does it use a variable frame rate?

after exporting a video from imovie, to quicktime, the audio has been duplicated. How can I fix this?

iMovie works best with uncompressed audio. If your track is MP3 or AAC, you may get better results by converting your track to the AIFF format and then using that in iMovie.
You can do this in iTunes. Go to iTunes/Preferences and click the General button. On the General page, click the Import Settings button. Choose IMPORT USING: AIFF ENCODER.
(note: remember what you changed it from so you can change it back later, before you import another CD)
Now, in iTunes, select your track. Then click FILE/CREATE NEW VERSION/AIFF VERSION.

Audio on the timeline, especially stream, tends to play very reliably. Is this project under any NDA or can you provide a FLA to examine? Let me know if you want to private message it and I'll shoot you a message.
What version of Flash Player are you targeting and is this AS2 or AS3?

Export a Quicktime puts audio out of sync.

Hi
I've just cut some footage capture on my iPhone.
When I export the quicktime the audio is out of sync. When I play the final cut timeline it's fine.
Any suggestions please?

Hi - Do you want the detailed explanation or the quickest solution?
If the quickest solution:
Click anywhere on your timeline.
Type Command + 0 (zero) to bring up your sequence settings.
When it opens change
!http://www.spotsbeforeyoureyes.com/SeqSettingH264.jpg!
to this:
!http://www.spotsbeforeyoureyes.com/SeqSetting422LT.jpg!
and click OK.
When you have done that a red render bar will appear over your sequence, click anywhere on the timeline and type Command + A and the type Command + R to render it all.
Now export your Quicktime movie.
Hope this helps. If you want the detailed explanation post back.

I am running Mountain Lion, I have also installed flipformac, divx, and vlc. They are working fine.

You can only use QuickTime Player 7 to play that 12 year old format.

Hi
Did You go via Compressor ?
Did You use QuickTime Conversion ?
I don't
I do
• In TimeLine set In and Out-Points to the full Movie/Project
• Select ALL - Clips and Audio
• Go up to Sequence and down to Render Only - down to Mix Down Audio
• then Sequense and Render Selected - Both (Video and Audio)
• then Export and as QuickTime .mov (NOTHING ELSE)
• I use to do - Not Self-Contained as it saves both time and space

Quicktime File Crashing Both Quicktime App and Finder in Mac, but Not Windows

Hi,
     I have a drive full of Apple ProRes Quicktime files. Almost all of them play perfectly, except 2. Those 2 files have played in the past, but I've had problems with them. They've come back to functionality in the past, but now they are not working again and I don't understand why.
     Whenever I go to open the files with Quicktime Pro 7, Quicktime X, FCP 7, Adobe Premiere or Adobe Media Encoder, I get the spinning beach ball and not only does Quicktime crash, but the finder crashes as well. If I go to restart the finder, it never comes back online and I have to restart my late 2011 macbook Pro.
     I've tried repairing permissions and on the Macbook Hardrive and have used Disk Utility and Disk warrior on the hardrive containing the 2 quicktime files. Nothing has solved the problem.
     At first, I thought the Quicktime files might have become corrupted, but I installed Windows 7, using bootcamp, on the same macbook, hooked up the external hardrive and was able to play the quicktimes perfectly in Windows with quicktime 7 (not pro, because I don't want to buy it just for windows). So, there is some sort of incompatability between these two quicktime files and my Macboook.
     Does anyone have any ideas as to what could be going on?

If you are on Windows Vista and trying to write something to
"Program Files" or its sub folders, write will not end up in the
right place as "Program Files" is protected. What ever you write
might go to a virtual store location. If that's the case try
writing to app storage folder.

Quicktime won't play on Mac but will on windows. Help.

Hello. I'm trying to help a student who's taking an online class using Course Compass. She is on a Mac using 10.6 and I'm using 10.5. Neither of us can get the videos in the course to work. The Quicktime plug in is getting activated, but nothing plays. Strangely enough, the play just fine on Windows. Here is one of the videos: http://www.mathxl.com/Info/MediaMov.aspx?movurl=http%3a%2f%2fmedia.pearsoncmg.co m%2faw%2fawbittinger_prealgebra_5%2fvideo%2fbpa05_0304e05MSTR.mov
Thanks for any help!

I see a box that says "Show legacy codecs" but when I check it nothing happens.
Believe this setting is to enable named list access of the legacy codecs for encoding purposes -- not playback.
As far as I know, you should have playback access under Leopard without having to do anything more. However, this assumes that you are, in fact, receiving the data stream. BTW: this is an RTS (Real Time Streaming) file, so make sure your streaming/transport protocols are properly set.
As to Snow Leopard, I am still unsure if legacy access is handled solely by the dual 32-/34-bit structure embedded in the OS in conjunction with the QTkit or whether the QT 7.6.3 Player must also be installed. (Since I was a QT Pro user, this was all done automatically for me when I upgraded to Snow Leopard.) As to streaming the file to Snow Leopard, I was unable to get the file to stream at all with either QT X or QT v7.6.3. (I.e., it simply keeps "negotiating" with the server until it is finally timed out.) Since many users have complained of streaming problems on a hit or miss basis, I am, for the nuance, considering this to be a Snow Leopard issue.

I've bought quicktime pro, entered the registration code but am directed to buy quicktime pro again

I've bought quicktime pro, entered the registration code but am directed to buy quicktime pro again. Quicktime 7 is showing 'Pro' after I enter registration under 'Registration'. I have an email receipt from Apple store saying it is purchased. Yet when I try to use the Pro features they are greyed out. Ripped off?

I've bought quicktime pro, entered the registration code but am directed to buy quicktime pro again.
Are you pressing the "RETURN" key to enter the registered information or the "TAB" key? "Pro" registration instructions clearly state that the "TAB" key must be used. If you used the "TAB" key to register the "Pro" key information and the "Pro" features are still grey, do you actually have a file loaded in a player window. I.e., the "Pro" features cannot be accessed if a file has not been opened in the application since they are context adaptive and, as QT Kirk pointed out, must be able to "see" the type of file you wish to edit since the features available may depend on which type of file you are trying to edit.

QuickTime Plays Audio But No Video

For the past few days everytime I play an mpg or mov on my QuickTime Player (7.3), I hear the audio but instead of seeing any video, there's only the native aqua gray screen. This not only happens with downloaded mpgs or movs on the Internet, which
plays fine in whatever browser I'm using, but also with mov files I've made myself with Final Cut Pro.
I've already researched similar problems within this forum from the past few months and I've tried various suggested solutions, like trashing the QuickTime preferences, restarting, repairing permissions, but nothing has changed. I've also gone into QuickTime preferences>advanced>mime settings, checked the "video" box, clicked okay, and restarted, but when I drag a mov file onto the QuickTime icon in my dock, the SAME THING happens, audio without video.
This hasn't affected anything within FCP, but I can't see any of my files in QuickTime. The only thing I did lately was install a third party program to change the look of my iTunes interface, but I completely trashed my iTunes program, all related files, including my music library, and reinstalled them from my backup drive, in case that affected QT.
Any ideas?

Hi Mark and welcome to the forums!
You really do need to update your OS to 10.4.11:
The 10.4.11 Combo Updater for PPC Macs is here: http://www.apple.com/downloads/macosx/apple/macosx_updates/macosx10411comboupdat eppc.html
And for Intel Macs: http://www.apple.com/downloads/macosx/apple/macosx_updates/macosx10411comboupdat eintel.html
as well as updating Quicktime to 7.5.5 from the Apple download page.

MP4 VIDEOS OPENS IN QUICKTIME WITH AUDIO BUT NO VIDEO?

I have downloaded may video clips from youtube with tubesock and they worked fine in quicktime pro and I was able to place them on Iweb, now they only play audio no video. What do you think happened.
I can play them with my VLC player and they are fine.
PLEASE HELP
Michael

Tubesock had a bug in their software which was allowing it to create invalid MPEG-4 files. The latest version of QuickTime will no longer play these invalid files, so if you just recently upgraded, that's your problem.
The fix is easy, though. The developers of iSquint have released a Debreaker application that you get for free with the download of the free iSqint (it's all free is what I'm saying Download that app and use the Debreaker to fix your files, and you should be set.
