    Where are these files from and what codec are they? (.mov doesn't tell you the codec).

     

    Try VLC Player (videolan.org) or the Perian plugin in QuickTime.

    Click on the file once to highlight it, and click cmd-i to Get Info. In the Info window, what is listed under "Codec", and what does "Open with" say?

    From "Get Info"

    Codecs: H.264, AAC

    Open with: Quicktime Player 7 (Pro)

     

     

    Screen darkens in a few seconds with Quicktime Player 7 and/or Quicktime.
    Plays just fine within iTunes.

    I have the identical problem with videos created on iphone 4S.  Codec H.264, AAC.  I get a video of a blank screen with no sound.

    I just solved this problem by downloading Nice Player and using that to play the videos.  Works fine.  I tried VLC, but I've had many problems with VLC over the years and couldn't get it to work, and perian is no longer being kept up to date.  So Nice Player is the way to go.  Good luck Lizkoh.

    i am not sure what codec is but these .mov files are videos created from my iphone. if anything, these videos should be compatiable to QT ?

    MOV is the generic QT file container. It may contain data compressed by any codec supported by the originator's QT codec component configuration. This does not guarantee that you have all of the originator's codec components installed on your system.

    If you mean the entire screen dims and then the display goes to sleep, then go to the System Preferences window and change "Display sleep" delay setting in your "Energy Saver" menu. If you mean the files will not play at all in the QT player app, the you may have a security update problem which prevents a file that should play from playing on certain systems.

    Sounds like a possible security update problem since the 4S files should normally be playback compatible if properly transferred between from the mobile device to the computer.
