Hello, I have the same problem
32G RAM, only used up about 10G during processing.
Version: 4.5.3, build 1374.
It kept quitting and I thought it was random (tried 5 times, adjusted 1000-700 once, all ended with a warning window).
Any update would be helpful.
Projector: Acer K132 + 1/2/4/10 X closeup dai. 52 mm.
Camera: Grasshopper 3 GS3-U3-28S4C-C (@ 1600 X 1200, 30 fps); Lens: 8-50 mm F/1.4.
Computer: USB 3.0, CPU: 2.6-3.5 GHz, GPU: 3G NVidia 970M, 32G RAM.
