Hi, After many hours of testing we have discovered that aerender.exe is unstable with certain effects. Note, this has only been an issue since moving to AE2018. The effects we have found unstable so far... Fast Blur (Legacy) Fast Box Blur Simple Choker Directional Blur If a basic comp is created using any of these effects (or combination of), and rendered by command line (aerender.exe), the comp causes aerender.exe to become very unstable. However, we have also discovered that these crashes depend on the amount of VRAM (GPU RAM) that is free on the system. On my system if the VRAM goes over 60-70% (which I can force by opening several images in Photoshop) then aerender.exe will render a few frames and fail every time. No error is given, even using the "-v ERRORS_AND_PROGRESS" flag. With the VRAM level back down to 50% or less, the renders always work. Command line used: "C:\Program Files\Adobe\Adobe After Effects CC 2018\Support Files\aerender.exe" -project "D:\test\AE2018_CrashTest folder\AE2018_CrashTest.aep" -comp "test" -s 0 -e 200 -output "D:\test\CrashTest\test_[#####].png" There is clearly a VRAM memory issue in regard to these specific effects, causing an instability in the aerender.exe AE 2018 (15.1.1), Windows 10 x64 Pro (16299.402), Nvidia GTX-770 4GB (Driver 391.35), Intel i7-7700, 32GB DDR4.
