I upgraded iphone 4S to iOS 6 today and noticed that .mov movies created in iPhone Camera app, when copied over to Windows 7 version of Quicktime Pro version 7.7.2 have a problem with the codec.   Movies I recorded before the upgrade play fine in Quicktime on Windows 7, but after the upgrade the movies have sound but no video.   I am using Windows 7 64-bit.   I tried uninstalling and reinstalling Quicktime Pro but the problem recurrs.  I've made several short movie clips and they all suffer the same problem.   Was someone in Quicktime division asleep at the switch when iOS 6 was prepared?  Any suggestions?


I should have mentioned that the movies play fine on the iphone itself.  They just don't show any video when played in Quicktime on Windows 7.

Problem solved for me anyway.  Another Apple thread suggested using Quicktime 7.7.1 instead of the newest version.  The only problem is that version does not show up on the Quicktime site and the next earlier version available is 7.6.  Version 7.6 played video but dropped frames and was not useable.  It has something to do with a progressive vs. non-progressive codec file.  Anyway this is an easy fix.


This is for PC Windows 7 not sure about Mac or other Windows versions


1.  Go to control panel in Windows and find programs and features.  Find Quicktime, highlight it and then go to the top and select uninstall or change program.  Uninstall Quicktime


2.  Go to this link  If you prefer to look at the website before downloading go to and search for Quicktime 7.7.1.


3.  Download this version of Quicktime and you will be good to go.  Quicktime and my editing software (Corel Video Studio Pro X5) all work fine now.


Life is good again.

    I have the exact same problem. I have iPhone 4s with iOS 6 installed and Windows 7 on my 32 bit laptop. Whenever I make a video using the iPhone camera, transfer that video to my laptop, and play with quicktime, the video only shows a black screen but plays the audio.

    The videos created with iOS 5 worked fine in quicktime.

    I need this fixed ASAP or the Samsung Galaxy S3 will start to look more appealing to me.

    Jonnosphere - hopefully someone will be able to give some advice on our problem.  I've since noticed that the .mov files created on iphone 4s with ios6 and transfered to my Windows 7 laptop play just fine in Windows Media.  There is just audio only in Quicktime, as you've also reported.

  • BeaverDam Level 1 Level 1

    My issue is similar. But, am not making videos. I just try watching videos, from internet searching, using my iPhone 4S. The video will play for a few seconds and then it's only sound. At this point the grey QuickTime background appears and the sound is only heard. No video though.  I updated today using my Mac book pro.

  • ElderGrue Level 1 Level 1

    Same problem here.  Also noticed that the video does not play in Picasa.  Just sound there, too.  I think somebody in Cupertino overlooked something.

    Exact same problem... just upgraded my 4s to iOS6 (also use Windows 7 64bit), and took video of the space shuttle flyover L.A. (which was stoopidly cool), moved file from iPhone to PC, and in Quicktime - sound but no picture. Also no picture (yet there is sound) in Sony Vegas HD Platinum 11 where I dicovered this issue trying to edit my vid. BUT... it DOES play with picture in new iTunes --- I hope this has a fast fix. When I thought it was a Sony Vegas problem... I tried everything and could not get the picture. Ugh.

    I have videos created on iPhone 4s that play perfectly when copied off the phone to my desktop PC.  But any video taken on the same phone after ios 6 was installed only show a black screen with video.   The video plays fine on the iphone.   What gives???????

  • iWhyme Level 1 Level 1

    Hi everybody,

    I'm having the same problems and I'm really disappointed that nobody from apple has solved this… since the first post was made on September 19.

    I hope that this will be solved soon !!

    Thank you.

  • Bright Badge Level 1 Level 1

    Same issue as all of the above here.

    -Videos work and record fine on the phone with ios6 installed. (I have the 4S)

    -Black screen with sound in Quicktime

    -Video works in VLC (Free Media player download)

    -Won't work in my video editing software- Corel Video Studio =


    Something changed with the ios 6 update, as I have videos on my phone from prior to the update and those are fine.

  • Bright Badge Level 1 Level 1

    Update: I successfully transfered the videos over to my laptop, which has Windows 7. They all work on there. Everyone having the problem running XP??

  • Gerald Edgar Level 3 Level 3

    Tried my iPhone 4.  With iOS6.  A movie recorded on the iPhone, moved to my Mac.  It played OK in QuickTime Player 7 and in QuickTime Player X.  These MOV files show codecs H.264 and AAC.  So is this only a QUickTime for Windows problem?

  • cptharpe2 Level 1 Level 1

    Im having same issue with laptop, windows 7 and quicktime pro. all are current..

  • Bright Badge Level 1 Level 1

    Maybe we that are having the problem need that codec: H.264 and AAC. Any ideas how to get them?

  • NDallas Level 1 Level 1

    I found that if I reinstalled Quicktime Version 7.60 (instead of 7.72) I could view the ios 6 created videos that I copied off the phone to my Windows 7 64 bit desktop machine.   Videos also played correctly using the VLC player for both new and old videos.   I reviewed the properties for both videos and they appear the same except for the Current Size property:   358 x 636 pixels on pre-ios 6 videos  and 1628 x 916 pixels for videos created using ios6.    I was still unable to view the newer video uploaded to Facebook as it shows "loading" and then displays an error message "The video you requested could not be loaded.  Please try again later".   I know others have been able to view the video online due to their posts about the video.   Still has be bumfudled!!  LOL

    The same problem occurs on my iPhone 4S (iOS6) and Windows 7 (64bits) :

    - no picture while playing in QuickTime for Windows, but the sound plays

    - green screen when editing in Vegas Pro, the sound is ok


    But :

    - the latest version of Media Player Classic plays the picture and the sound without problem

    - Adobe Premiere Pro CS5 handles the videos properly


    I phoned Apple, explained the problem : I was told that maybe QuickTime will soon be updated, since the last update is dated May, 2012. He said something like : wait and see, you'll receive an QuickTime update via Apple Software Update, or via iTunes, when the problem corrected.
