A little late to this, but…

After several “output module failed” errors and some digging I found that Quicktime for PC does not support more than 21 cpu cores (including virtual/hyper-threaded). I don’t think it’s for all of the codecs, but h.264 definitely does not work with more than 21. Anytime I want to export h.264, I have to run msconfig from the start menu, go to the Boot tab, click on “Advanced options…”, check the Number of Processors box, set it to 21, and reboot. Everything seems to work fine after this, I just have fewer cpu’s to work with.
