  HELP – QT stuttering on interlaced video playback.

  Posted by Andy Stokes on March 20, 2008 at 4:15 am

  Hi all,

  I’m having problems with Quicktime playback of Interlaced video.

  For testing purposes, I’m playing back a PAL 20 second h.264 clip on a secondary display attached to my MacBookPro with the Apple DVI-S-Video adaptor (set to 720×576 PAL).

  When I play the clip, it stutters/flickers (almost like the fields are inverted).. If I pause then play the movie repeatedly the problem seems to rectify itself for a few minutes, then it happens again, until I pause/play again.

  I have tried different codecs and different players, but all with the same problem. It even happens when I “present movie” in quicktime. Has anyone experienced this problem? (and hopefully found a fix). I need to solve this ASAP since the clips need to loop for an unattended tradeshow setup.

  Any help would be appreciated.

  Cheers,
