I am trying to import red epic dragon 6k footage into Adobe After Affects and so far it is proving unsuccessful. I am fully updated and Premiere runs the 6k files without incident. I noticed in the "supported video" help document seen here http://www.adobe.com/products/premiere/extend.html that After effects should be able to handle this. Is there a patch on its way? Any help would be extremely appreciated.
The document that you linked to is for Premiere Pro.
There are some improvements regarding RED import in the next version of After Effects, coming soon.
