Well, reactivating codec isn't anymore an option on CC 2014 ???
This is a big deal
We are not speaking about realiable codec etc, in general h264 isn't reliable because of it's destructive nature
We are speaking about Work in general and how Adobe tends to complicate things in general.
-> H264 is used most of the time to client review, team review, iterating version fast, etc...
Doing just that is a pain in the *** on the artist side, doing that in AME IS time consumer, IS complicating the Artist work
Definitly Adobe don't gets their consumers...
