Apple has just released an update to QuickTime that fixes a problem introduced in QuickTime 7.4 that caused problems with After Effects renders. In short, when a render to a QuickTime file took over 10 minutes, QuickTime thought it was an attempt to hack the file and would abort the render. (Frank Capria reported this problem – and gave workarounds – here.) This has been resolved by the 7.4.1 update, which should be noted was out in record time.
You can update your Mac by using clicking on the Apple icon in the menu and selecting Software Update, or by going to Apple’s downloads page. Little information is given on the web site about the specific fixes; MacWorld provided more details on their web site.
And there was much rejoicing…
