On Win10 running Intel i7-7700K with a GTX1080ti, 64GB Ram
Rendering a sequence 4096x4096 with Alpha channel and masks.
Setting render off as QT Animation with Alpha. If i keep AE window open it seems to progress well, as soon as i move over to Premiere and continue to edit, i hear the chime and see AE has stopped my render.
Is this a memory issue?? Never come across it before.
Any help or fixes much appreciated.
It's possibly a memory issue. What are your memory settings in preferences?
You might consider updating AE to the latest version since you're not on version 14.2.
You also might consider sending it directly to the Adobe Media Encoder. That usually does a better job of working in the background.
