We’ve received feedback from some of our users that have recently updated to the latest Apple OS X Mavericks, and are having major issues in After Effects.
Apparently Apple is doing away with Quicktime, which creates a problem for our workflow that recommends using the Quicktime ‘Animation’ codec, and also causes a couple of our templates to crash After Effects that use Quicktime videos as pre-rendered assets (Pro Motion Menu Kit 12 – Making Memories, and Pro Motion Menu Kit 13 – Rays of Light).
We are working on a solution to this problem and should have a fix shortly!
You can bypass these issues by rendering to a different codec (Quicktime Pro Res or H.264) and convert the Quicktime assets loaded by those two kits to these codecs as well.
