Quicktime 7.2 only plays audio in safari

Since I've upgraded to 7.2, all quicktimes in the browser now only play the audio. If I reload the page, the movie comes thru. Is there a fix/patch for this behaviour?
I am on a 2GHZ Inte Core Duo Macbook. with OSX 10.4.10
thanks

I've seen dozens of posted "fixes" and most seem to generate to other Web Sites by way of RSS feeds. They all seem to appear after any Mac OS or software update when viewers post "solutions" to issues.
Since those pages generate revenue from page hits it doesn't matter to them whether or not the fixes have actually been confirmed, are posted by other users or are even practical.
What works in one case may not even apply to another and each user.
Example in point is the famous "QuickTime question mark" that many users have experienced. Some were caused by browser plug-in changes that attempted to open Flash media files via QuickTime. Others were errors in Safari browser that failed to properly display .m4a files and a third is the "no video" problem posted here.
Each require a different "fix". Apple fixed the .m4a issue with the 7.2 update but many users have yet to install it. Adobe address some security issues and has updated their Flash player software and it fixes other errors.
I'm sorry if it appears I've singled your post out. It was not my intention to try to discredit your answer to any post here but that suggested "fix" (removing the QuickTime browser plug-in) would only repair Flash media issues (by disabling QuickTime).
We "regular" posters need to ask a question sometimes before giving out a specific fix. And we must understand that a wrong answer can do more harm than good.
And removing any plug-in will, obviously, cause other features to not work.
O.K.
Off my very short soapbox.

  • I am using FC Express HD, and for some reason, when I export a Quicktime movie, the final movie will only play audio, and the video is black.  I only get the actual video if I export as self contained, or if I exportusing quicktime conversion. Why?

    Should be able to go into your sound preferences and choose your output device, you can also try downloading Airfoil and try that, it's a pretty cool app.

  • Panasonic .MOV files only play audio no video in Premiere Elements 11??? Not Working Help

    Panasonic .MOV files only play audio no video in Premiere Elements 11??? Not Working Help

    It all depends on the codec the file uses, Karli.
    What model of camcorder is this video coming from?
    Are you working on a Mac or a PC? Have you got the latest version of Quicktime, per the program requirements? When you started your project, did you select the settings for a DSLR at 720p? This is a vital step since it will activate the components your computer will need to work with many of these types of files.
    BY THE WAY, KARLI--
    PLEASE do not post the same question more than once on this forum! You've already got a thread going with this same question and several responses posted. It's very confusing when you post the same question a second time and start a whole new discussion.

  • YouTube films are only playing audio, no pictures any ideas out there. Mike D

    YouTube films are only playing audio, no pictures. Any ideas out there I have already cleared out my Safari history as suggested in another post, this solved the issue for a day but back to square one now.

    I am having the same problem. Last night during a long call using headphones, suddenly I could not be heard, but I could hear the person I was talking to. I did not try the speaker. This morning with out the headphone twice I placed a call and heard no ringing, but the call did connect as I was told they got the call, but no one was there. I just reset the phone and will see what happens. I was thinking of going to the Apple store were I got the phone, but if they are going to ship it off rather than exchnage it, that is a no go for me at this point.

  • Quicktime only playing audio

    Downloaded some videos from my gfriends video camera & all QT plays is the audio. Tells me that I may not have the components needed to play videos. They are .mov files. She has a newer mac & they play on hers. I downloaded the latest version of QT and it still only plays the audio.
    Info tells me that the codecs are MPEG-2 SD Camcorder, Integer (Little Endian), Timecode.
    I'm lost on what to do.

    Dear KQK, I'm running Quicktime 7.5.5 and I don't get any sound when playing back some of my AVI files I downloaded from a file sharing network. About 1 in 10 has no sound. If you can help me with this problem, I will gladly buy your PDF file about Quicktime. Godspeed

  • Changed TV out to off but ipod still only plays audio and no video

    Just recently my ipod decided not to play video. All the videos in the video folders are gone and now appear in the music folder. Even the video podcasts no longer appear in the video podcast folder. I have changed the TV to out to off and still it continues to do the same thing. I am not sure what happened, I don't believe I changed any settings or anything. I would hate to reset the ipod and lose everything. Need help, thanks.

    It plays fine on my other pc, but I only get audio and no video when I open it on this pc. It shows up like static lines on a tv that has bad reception.
    Open your QuickTime control panel (either via the Control panels, or by going "Edit > Preferences > QuickTime Preferences" in the Quicktime Player). In the Advanced tab, uncheck Enable Direct3D video acceleration:
    ... and click OK. Quit and restart the QuickTime Player prior to checking to see if the settings change has had any effect.

  • Why do my old QT files only play audio on QT X on Lion system

    I have some old NTSC (DV/DVCPRO) videos that play well on my old Leopard system but on my new Lion Macbook Pro, only the audio will play.  The video will play from within Finder but when I double click and it launches QT, QT behaves as if its only an audio file.  This is true when I try to import into Final Cut X.  Final Cut shows it as an audio file BUT 2 of the files DO show video.  These are all 720x480 video dumps.  So 7 files show as audio files and 2 work correctly.  And all work fine under Quicktime 7.7 under Leopard 10.5.8.

    Please disregard this posting.  I took the old file and ran it thru compressor in a 422 format and now everything works fine and only took about 10 minutes per hour of video.  I don't know how to cancel a request and I'm really pressed for time.  Thank you.

  • Videos only Play Audio

    i have an iPod video and iTunes on an hp running windows xp. when i download a tv show, it downloads fine, but it only plays the audio, not the visual of the tv show. it does the same for podcast(idk if podcast's are supposed to have video). i was wondering how to fix this. Thank You

    Have you installed any third-party QuickTime codecs (such as DivX) or iTunes enhancers or plugins since your videos last worked? If so, try removing them and see if matters improve. If not, or you haven't installed any third-party items, you might try uninstalling and reinstalling QuickTime. You can get the download from the QuickTime tab above; just select the option to download without iTunes.
    Caution: as with any significant software installation, it's wise to make a backup of your important documents - in this case your purchased tracks and videos - before attempting the installation, just in case something would happen to go wrong.
    Hope this helps.

  • Embedded video files only play audio

    The newest version of Keynote (v. 4) in iWork '08 will only play the audio portion of video files I add to it. The first frame of the video shows in the navigator panel, and the files show up and are viewable in the media browser. The selection handles for the video files are visible but that's all. This version also doesn't show the video content created in previous versions of keynote. In version 3 files I'd had .avi and .mov files that worked fine. I've checked the quicktime settings in system preferences to make sure that they were set properly. Suggestions?

    After posting the original question about the newest version of Keynote (v. 4) in iWork '08 only playing the audio portion of video files I add to it, I tried every possible fix.
    Since I'd been using a newer PCI video card recently, I tried just hooking up the monitor to the AGP video card that was still installed and it solved the problem.
    If anyone is considering using Keynote v.4, make sure that you have either an AGP or PCI express slot for the graphics card you use since a regular PCI graphics card won't support video or animation files you add to Keynote.

    I have not got quicktime on my desktop pc - I have not loaded any plugins for quicktime - so why does one play and not the other? - and how can I get the other to play please?
    (I have updated my graphics driver )

    Are Forums any good? - whenever I post I always end up having to answer my own question eventually! - aaah well, anyway for the benefit of anyone interested I suspect it is flash player in firefox browser that is playing the MP4's and perhaps it cannot cope with the higher resolution format.
