I put premiere pro CC edits in After Effects CC through dynamic Link every day. Since I upgraded my systems to Maverick and first installed the 12.0.1 and afterwards 12.1 the rendering of the After effects projects that have Dynamic Link Edits on the timeline slow down from 10 hours (in12.0 on Mountain Lion) to about 90 hours. When I replace the dynamic Link with a QT Movie, it renders about 10 hours again. It is normal that Dynamic link slows dow the rendering, but this is extreme and since this wasn't the case on Mountain Lion and 12.0 for the same project with the same dynamic link, not normal. I couldn't figure out what causes this. Is this Maverick on my 2008 Mac Pro ? is this a bug in 12.1 or dynamic link ? Or can I solve this with a simple setting somewhere in Maverick or AE ?
I was having a very similar problem. I wasn't able to solve the issue as such, but I did find that if I quit After Effects before attempting to render my PP timeline with the linked comps in it it worked just fine. The speediness we had pre-Mavericks returned.
Now, admittedly, this isn't a perfect solution. I mean, every time I want to make a change to one of the linked comps I need to re-open AE, make the change, then close it again, but it does let me finish rendering the project before I grow a long gray beard.
Definitely something to put forward to the powers that be.
Good luck and hope this helps!
I'm going to try it, I noticed that it isn't happening all the time. I think you shouldn't touch premiere at all when rendering. Yesterday I rendered two 15s ads with only one text layer that had different information. They both had the same dynamic link sequence and all the graphics and effects were the same. The first one rendered in 7 minutes, the second in 16 minutes ... I once thought it had to do with the cache folder that was growing to his limits but when I purged the cache it wasn't solved.
I have had some issues with render times and serveral slowdowns in premiere, after effects and encore after mavericks update, I found in other forums that the new feature called power nap was the problem, after disabling it, adobe prodcuts work like a charm. Go to your application folder, right click your app and check the option to disable power nap, tell me if it work for you.
