>Avoid QuickTime 7.4 for Now

>UPDATE: QuickTime 7.4.1 Fixes Rendering Bug

*******************

Just like with QuickTime 7.2, the newly updated QuickTime 7.4 seems to be creating problems when rendering, not only from After Effects but even from FinalCut Pro. People report getting a errors like:

After Effects error: opening movie – you do not have permission to open this file (-54)

There are some suggestions that this is the movie rental DRM in iTunes that tries to verify the copy-protection in all open QuickTime movies every 10 minutes.

The work-around is to render to a file sequence, such as TIFF, and then either assemble that into a QuickTime movie in QuickTime Player Pro or by importing the sequence into AE and rendering out a movie from that sequence.
