I have to believe the whole issue is related to some X265 setting, although I have failed to find it. If I output several UHD movies to a single UHD disc (low bitrate as a result of a CRF of 23 or so) it seems to sync ok. Interestingly, the higher the bitrate used the worse the sync issue gets. if I can find a way to get past that annoying audio sync issue when using TSMUXER to create UHD-BDs, I'll feel better. It also shows how much wasted space is used on the original UHD discs (probably just to make them harder to copy). It's just one more example of how superior X265 is to most HEVC encoders. The UHD with a fixed CRF was shrinking much smaller than I had expected. I can't wait to get a chance to see how good it looks after compressing like this.Īctually I was surprised in my testing also. While I managed to watch a few other 4K converts I did, and they looked better than internet streaming (UHD via VUDU) of the same titles, Valerian just finished over night so I didn't get to watch it yet. (70gig was using MakeMKV to rip to MKV file without compression/etc.) For example, Valerian And the City of a Thousand Planets compressed from 70gig down to 13gig.

Playing the files via SPMC 16.7.4 on my FireTV Cube with my Sony XBR 4K TV, the TV reports HDR and colors look right (good). With i8700k cpu, it takes anywhere from 7-9hrs depending on the movie.

using Alt Movie Only, CRF=20, Encoder+better(fast), "MKV Container, HEVC, NO_RESIZE, Intact Audio" First off A+ for adding UHD to MKV support.
