  • can’t encode QT H264 1080P ?!?! CS6 / windows 7

    all of a sudden i can’t encode videos to a QT H264 in 1080p

    let me elaborate:

    it started that i wanted to export a 1080P project in premiere cs6 to a 720p h264 quicktime. everything worked fine.

    then i did the same process exporting the a 1080p version. the only thing i changed was the size obviously (from 1280×720 to 1920×1080) and the max bit rate from 6000 to 10000.

    it didn’t get over 0% and crashed premiere.

    so i exported a 1080p version with the animation codec and imported that file into the media encoder. i set the file to the 1080p 25i preset. changed it from interlaced to progressive and hit start. after 8% it just hangs and does nothing. i let it be for more than 20 minutes but nothing happened. again. if i do the same process in 720p it works fine.

    my last resort was to do the export directly via quicktime pro. same thing. after 8% it just says “export controller has stopped working”.

    i googled that but coulnd’t find any useful help

    you guys know what to do?

    The QuickTime system will often fail when using a large number of threads. This occurs most on computers with a large number of processors (CPUs), including computers with a large number of virtual processors created through hyperthreading. This is especially a problem with Apple’s H.264 exporter component within QuickTime.

    To get around this problem, disable hyperthreading or reduce the number of processor cores available to QuickTime.

    This document on the Adobe website describes how to do this:

    that’s really unfortunate. apple needs to release a 64bit version of Quicktime for Windows.

    I can’t speak for Apple, but I believe that the QuickTime system is EOL (end of life) and won’t be getting any such updates.
