Finally! I’ve just managed to render out a composition in After Effects in the Quicktime format!
Here’s how I fixed it:
1. Find the AE application at: C:Program FilesAdobeAdobe After Effects CS6Support Files
2. Next, right click the application called “AfterFX.exe”
3. Go to the compatibility tab and check the box “Run this program in compatibility mode for:” and then select your operating system (vista for me).
4. After that, still on the compatibility tab, under the heading “Privilege level” check the box for “Run this program as a administrator.
By the way this is on windows vista so I’m not sure whether it’ll work on other OS systems but worth a try. Also I’m not sure that step 3 is actually necessary but I don’t want to try it without incase I screw it all up again. Hope this works for you.
