    Windows 7 x64 - Encode h.264 results in jerky video in WMP 12


      Windows 7 x64 - Encode h.264 results in jerky video in Windows Media Player (WMP) 12


      System: Windows 7 Ultimate x64 EN, Adobe Master Collection CS 4 Win En


      Please download the sample file here:






        H.264 HDTV Testvideos


        Profile: 1280x720 fps 30, square pixel, progressive




        For Testing purpose, just converting the original within Adobe Media Encoder.


        Profile: same as Source


      1) The original source files play fine using any player, so the hardware of my test systems (3 computers) is ok


      2) When exporting the Video to H.264 the resulting video is jerky in Windows Media Player and Quicktime


      3) When converting the jerky result video again, but now into WMV, it plays fine


      The problem can be reproduced on all 3 machines.


      It seems to me that Windows Media Player and Quicktime enforce their own h.264 decoder which has problems playing Premiere Exports.


      These Players seem to play the file properly:

      - VLC Media Player

      - Media Player Classic Home Cinema

      - Adobe media player


      So how can one be sure that the Premiere h.264 exports are just fine and the only problem is on decoder side? However, I feel very uncomfortable not being able to play the h.264 files within Windows Media Player 12, which has uses the built-ind Windows 7 h.264 decoder.


      Any help is highly appreciated!


      Thank you
