Pete, thanks also for your input. Those of us with high-end CPUs probably don't realize (I didn't) just how much CPU processing UHD uses. I do know when CloneBD "hits the wall," it really does appear dead. I once let it go for about a full day and it still was going (I say "going" but there was no indication of any CPU activity). Your advice, "just don't" is good advice.
EmpathicEar, what works for me now is that my new computer has an NVIDIA Quadro card which CloneBD can take advantage of CUDA hardware acceleration. From what I've read, the AMD (including Radeon) hardware is a "work in progress" as far as CloneBD hardware acceleration is concerned. I updated the drivers on my previous computer that has a Radeon card and updated CloneBD and still no luck. CloneBD allowed the dots to be "checked" for AMD hardware acceleration, but still didn't employ that hardware acceleration in the UHD encode.
At this point, CloneBD appears to be the best solution for "shrinking" UHDs. I have always liked BD-Rebuilder but it still appears not to be able to take advantage of hardware acceleration and thus is much slower. CloneBD has a great interface and plenty of options for full disc, feature-only, and even whether to keep Dolby Vision, or downgrade audio to DTS. The caveat being that if you're doing UHD, having an NVIDIA card is nearly a "must," at the very least, highly recommended.
