Hi Ting, I ran another test today. The source was the factory-made DVD for MIDWAY,. First I used DVDFab to copy Movie Only to my C Drive. the source files are 4.52 GB. I started the DVD to Blu Ray copy using AI Enlarger at 7:22 AM my time (US Central Time). The job finished at 9:07PM my time . It took 13 hours 45 minutes. My PC is pretty high-end. It was top of the line a couple of years ago, but it is still pretty respectable even by today's standards. Windows 10 Pro, CPU is i7 8700K, 6 cores, 12 threads with auto-turbo up to 4.5 Ghz. It has 32GB of DDR4 RAM and a GEForce 1080ti video card with 11GB of video RAM. I can't even imagine what it would take to run AI Enlarger with a lower-specs computer. I suspect that the sAI Enlarger module is not taking advantage of the CUDA cores in my video card. I can shrink a Dual Layer Blu Ray movie to BD 25 in 30 minutes or so. I am attaching the logs for this run here. Please let me know if you need any additional info. The dvdfab_ai log file was too large to upload so I copied a few lines from the beginning and a few from the end to dvdfab_ai copy.log. ALso, every time I need to use the AI Extender option I have to rerun the 11601.exe installer in order for the AI Extender module to show as being purchased and activated. If I finish one run DVD to Blu Ray with AI Extender, close DVDFab 11 and start it again, the AI Extender activation is missing. But that is a different and minor issue compared to the long running times issue I am reporting here.
Thank you for your time and consideration.
