I just want to make you aware of some time i wasted last week. Im not a professional editor but quite into PP and AE. On my so far most complex project i have about 60 seconds done in AE. when Exporting the whole project 1 from 100 times the export works. It stops exporting always around the same time but never at the exact time stamp, i varies always by 5 seconds. Its so frustrating that the preview playback works but the export never. I tried everything to fix this export bug, even changing my AE Project slightly (but who wants that ?) I'm fine with slow export times when things are complex, but where not talking about that i did an starwars, just couple of transitions.It neither an RAM or GPU Problem or an Driver Issue. The feedback while it stops exporting is so useless that that is really hart to track down the "why". I spend 2 days nailing down the problem and some fix may helpen (pre render the timeline). But why this helped my i cant tell, and please adobe fix those problems, i like PP and AE but this experience is absolute not good. If i would be an professional editor facing this problem while clients are waiting must be frustrating and makes you look dull in front of them.
