Question
After Effects: Unable to allocate 0.000MB of memory.
I you are seeing this every time you close a project I believe it is an issue between AE 2019 and BlackMagic Desktop Video Drivers 10.11.2 and later. Running 10.11.1 will fix the problem, as will sticking with AE 2018. BM have been notified and hopefully will be providing a fix. I would be interested to know if anyone else has seen this as we've had it on two Win 10 systems and on Mac also.
