So some good news on the UHD BD authoring front! DVDFab just released their UHD BD authoring tool. It can handled HDR10 and Dolby Vision. I’m going to give it a try. However, like other DVDFab authoring tools, it has no menu authoring tools.
It’s $40 for a license and it can author to BD-25’s, BD-50’s, and BD-100’s (BD-66’s are probably an anomaly to account for since they aren’t an even multiplier).
The free community sourced TS2UHD is making some progress but it’s still very pre-alpha at the moment only being successful with certain players and TV’s. It will get somewhere eventually I hope.
