i am using after effects cs5 10.0.2.4
before installation of quicktime 7.6.9, the openGl previews were available and i am frequent user of openGl for previews. After installation of quicktime, this option is greyed out in preview preferences. The openGl info button shows nothing.
I uninstalled quicktime and the openGL previews were available again.
adobe website's system requirements for AE CS5 are fully met. I have latest catalyst center for my HD4850 graphic card.
here are my system specs:
OS: WIN 7 x64 sp1
RAM: 2 gb
HDD: 1000 gb
MSI HD4850 512mb graphic card
Catalyst Control Center 11.6 Driver version 8.61 (latest available on amd website)
OpenGl version 126.96.36.1993
and also i only found 32 bit quicktime installation.
Please help in this situation.
Have you tried different/earlier versions of Quicktime?
