Suddenly, about a week ago, whenever I try to open these files in QuickTime, I receive a message saying the required codec is missing.  Yet, these same files will open in iTunes.


In Quicktime, when I click on "Find out more," I'm taken to an article titled, "Media formats supported by QuickTime Player," Article: HT3775, which lists MPEG-4 as a supported format in QuickTime.


I do not understand.

    I'm not sure what settings you used, but I would check again.  H.264 is support on the Mac if you have Quicktime 7 or higher installed.

    I have checked.  As always, I use Handbrake's default settings for "iPad2." I do not root around in Handbrake's customization settings.


    As the files in question open in iTunes, I assume the problem lies somewhere in the QT side, maybe via a corrupt preferences file or something.  I do not know.  I just wondered if others had experienced the same thing.

    Handbrake is not using Quicktime for encoding, so it may produce H.264 that could be incompatible.  It is an open source project is not by guaranteed to be Quicktime compatible.  If you encode the H.264 by running it through conversion program such as Apple's Compressor, it will always be compatible with Quicktime.

    Brad Wright2,


    You have a good idea, but I do not know how to run the video through Apple's Compressor.  I assume it's simple, but you use a term I have not before seen.


    Thank you.

    You want to convert your DVD video to Quicktime first, and then encode your video with compressor.  Compressor gives you the most options for converting the video.  Apple's compressor gives you lots of options for setting the size and quality of the H.264 file you want to create.  Since it's Apple, the H.264 you create will work in Quicktime.  Compressor is also really cheap at $50 on the Apple store.


    There's several good options out there for converting DVD video to Quicktime.  I recommend taking a look at DVDxDV.
