For several months now, when I receive videos in Quicktime, I only hear the audio and see no video.  I don't understand what the problem is.  I am up to date on my upgrades and I use the Lion operating system.  Does anyone know how to fix this?


MacBook Pro, Mac OS X (10.7.3)

    To fix a problem, you have to know what the problem is. As always, the first step is to determine what codec components were used to create these files. Since you say you can hear the audio, the files must be loading and playing. So open your Inspector window and tell us what audio and compression formats are listed in the window.

    Here is what I understand.  This video was created on a Mac.  It was compressed using Microsoft Windows Media Player.

     

    Here is what comes up in the Inspector Window:

     

    Format:  'WMV3', 640 x 480

    Windows Media Audio 9 Standard*, 2 channels, 44100 Hz

     

    FPS: 14.99

     

    Data Size:  8.6 MB

     

    Data Rate:  765.23 kbit/s

     

    Current Size:  640 × 480 pixels (Actual)

     

    Is this helpful?

    Do you have any of the Flip4Mac WMV software codec components installed?

    Yes, in fact I just purchased the pro version thinking that was going to solve my problem.  Restarted my computer and still did not work.

    Have you installed a major OS update recently? If so and the codecs were installed prior to the update, you can try re-installation to ensure they are being recognized.

     

    Do you normall re-start the system following installations and repair disk permissions?

     

    Is the Flip4Mac version compatible with your OS/QT software combination?

     

    Have you installed any codec components which may comflict with the use of the Flip4Mac codec components or run conflict tests on your own?

    i have uncompressed 10-bit video and I have the same problem on Windows 7. Do I need to install a codec component in order to see the movie?

    Despite its name, uncompressed video is actually a digital video format requiring a codec (encoder-decoder) component to both write and read/play the data properly. Whether or not you "need to install" a codec component depends on the software already instlled on your system. If you are using a video player that has a built-in uncompressed 10-bit codec, then you would not need an additional component for playback when using that player application. If you are using an "open" player that employs codecs stored by the OS for general shared use by one or more applications, then an appropriate codec must be included in this configuration. In most cases, uncompressed codecs are considered "pro" editing software and are installed by commercial "pro" editing software packages. If you are not using a "pro" editor application, then you may have to install the required codec manually if you can find or purchase one. If you cannot locate the required component for independent installation, your best bet would be to have the person who encoded the current file recompress the data to a compression format supporterd by your system.
