Hi Brad…
Why I’m curious….
is that if you Cache Preview in AE (using GPC) then that’s (in theory) what PPro ought to be looking at when rendering…. so if you see a blue bar in AE on the seq (this is from my memory not user experience) then should be reading cache off the disk and this is essentially the same as the manual set proxy method.
to answer your other question…
If you Drag an AE project to AME…
then you can set batch renders of all the comps…
once rendered…you could then re-open the AE project and connect the AME renders as Proxies to the originating comps…
AE CC (as I’ve seen on Adobe’s site demo) will allow you to AME render right from AE…
does that help?
