    Recovering Quicklook for DNxHD on OS X 10.9-10.10

    Posting a little tip that corrects a little annoyance with Mavericks and Yosemite.  It is no longer possible to preview DNxHD Quicktimes (and all other QTs in codecs other than Prores ou H264) with the space-bar.

    It turns out that the old behaviour can be recovered by "transplanting" the quicklook components that handle quicktime files from a copy of OS X 10.8.5.  It works fine - although you need to redo the steps when you update the OS, and you need access to a machine with 10.8.5 to grab the files.  

    On a machine with Mountain Lion installed take a copy of the following two files/directories:

    /System/Library/QuickLook/Movie.qlgenerator

    /System/Library/Frameworks/Quartz.framework/Frameworks/QuickLookUI.framework/PlugIns/Movie.qldisplay

    Put them safe somewhere (Avoid FAT32 formatted USB keys as permissions may be lost - zip them if in doubt)

    On the machine with Mavericks/Yosemite, take a copy of the existing files/directories in these locations and replace them with those copied from 10.8.5.  Be careful to only replace these files (not any part of the directories that contain them - doing so will create major headaches)

    Run the following commands from the Terminal to repair permissions (you need to have a password set on the account):

    sudo chmod -R a+x /System/Library/QuickLook/Movie.qlgenerator

    sudo chmod -R a+x /System/Library/Frameworks/Quartz.framework/Frameworks/QuickLookUI.framework/PlugIns/Movie.qldisplay

    sudo chown root /System/Library/QuickLook/Movie.qlgenerator

    sudo chown root /System/Library/Frameworks/Quartz.framework/Frameworks/QuickLookUI.framework/PlugIns/Movie.qldisplay

     

    Enter your password when prompted (nothing will appear this is normal)

    Reboot.

    The Space bar will now preview DNxHD files and QT reference files as before.

    This should also work with El Capitan, but you will probably need to deactivate System Integrity Protection to replace the files (boot in Recovery mode (Cmd+R on startup), Launch Terminal and type csrutil disable), reboot, replace the files then you can probably reenable System Integrity Protection (csrutil enable in recovery mode) - I have not tested this.

    Re: Recovering Quicklook for DNxHD on OS X 10.9-10.10

    Cool tip.

     

    Note that the feature was removed as a security measure.  Third party codecs can cause malicious code to be inserted into QuickTime movies.  Using QuickLook to preview can allow allow that malicious code to be executed even without the file being opened.  This is also why third party codecs are not supported in QuickTime X anymore.  Apple only supports codecs they supply in QuickTime X.  You'll see any file encoded in an unapproved codec will be automatically transcoded when you attempt to open it in QuickTime X.

     

    there needs to be a simpler override for Pro Video Users.

    Fantastic Tip!!!

    Just successfully used it on El Capitan 10.11.3 using the csrutil disable and enable commands in recovery mode :)

    Thanks a Million!

    And for those of us who don't have Mountain Lion installed is it possible to post these two files somewhere? Would be much appreciated.

    Can we go back to the way audio nodes used to be selected? Please? ie if you have audio nodes at the same time on selected tracks; then selecting 1 audio node selects them all at that time. Having to shift select nodes or add an in and out is time consuming and counter productive. At least make it an option.

    Re: Recovering Quicklook for DNxHD on OS X 10.9-10.10

    That really made my day, thank you very much!

    A while ago, probably when 10.9 came out, I wondered if doing so would be possible. All Mac "power users" around me said nope. And I gave up and just hated Apple each time I hit spacebar on a DNxHD QuickTime file I came across...

    Never give up on hope!

    Thanks - for some reason copying and pasting the chown commands out of the PDF didn't work. It came up asking for correct usage. Copying form Janusz original post worked. Who knows - they look identical and I imagined you just copied hte post..
