Apples has released a new QuickTime (QT) version which did seem to fix the rendering issue that the previous QT version caused when rendering in After Effects. Rendering beyond 10 min has been reported to be working from many sources . As the 7.4.1 update addresses security issues as well, including “Impact: Visiting a malicious website may lead to an unexpected application termination or arbitrary code execution” the update could be naturally needed by all QuickTime user. Quicktime 7.4.1 has been made available by Apple for Leopard, Tiger, Panther and Windows.
