I don't understand what the hell happened on this one. I did a partial copy of Ready Player One UHD and compressed to BD-R (25 GB) in the options with maintain original menu and direct play main title both checked. Output to ISO. I kept the Dolby Vision track. I expected the output to be roughly 25GB. Instead the ISO is 5GB. This is using my nVidia 1060 card for decode/encode. I've attached my log.
