UHD BD to BD?

[X5gb]

I like to preview my encode as it goes along just to make sure everything goes to plan, don't want to be encoding for 2 days to find out there is glitch or freeze like I had twice with Grease and with CRF you are seeing the final encode unlike 2 pass. Also in the case of Grease the encode with CRF20 is using a bitrate of on average 35000kbps which is higher than the 2 pass variable 30000kbps I chose initially so am more than happy the way the encode is turning out using CRF. Another 17 hrs to go, hopefully no freeze towards the end this time.
