UHD discs have three layers on one side and will need new burning laser and firmware for the task.
Only commercial UHD 4K disc use the odd 66GB. However, several UHD Bluray burners already support dual, triple and quadruple layer burning (25, 50, 100, 128GB).
I've read several other forums on this subject and most posters appear to be hung up on the idea of the 'commercial' standard. Consumer software has never been able to produce 'commercial' quality or most of the 'commercial' standards.
If PD16 could just create a regular Bluray structure and menu, but encode the file to 4K (AVC or HEVC), the disc would probably play in any 4k player. Personlly, I could care less HOW the disc was create as long it played with the menu.
-------------------
I have tried that, using TsMuxer, it creates the structure as BR but the video is 4K. The Samsung 8500 does not recognize it but it plays fine on the pc with Media Player Classisc and VLC including menus.
The file structures of a commercial 4K and HD BR are exactly the same except for their content of course. The 4K and the HD version have both the
exact same files:
AACS
BDMV
CERTIFICATE
Below is contend of BDMV:
AUXDATA
BACKUP
BDJO
CLIPINF
JAR
META
PLAYLIST
STREAM
Indexbdmv
MovieObject.bdmv
But the content on some must differ from UHD and HD, and perhaps that is all that needs to be altered by CL. Their 4K HEVC is playing fine on the 8500 and is looking great, that part is the most complex and difficult, yet was
already done years ago.
The disc is ROCKY MOUNTAIN EXPRESS filmed in IMAX and true blue 4K and is reported to be one of the best UHD experiences. And who can resist the impact of a steam engine with the sound turned up !!!
It has a 25GB HD and 50GB UHD version in the same box. Both discs are 95% full, so here, to obtain spectacular UHD, the storage capacity is
only doubled.
An other outstanding one I like is BBC PLANET EARTH II reported to be downconverted from 5K original video.
The sad fact is that perhaps 75% of UHD discs are hardly better looking than their HD versions because they did not originate in 4K.
I have hours of 4K video of our vacations captured by the Sony FDR AX100, still the standard as far as PQ is concerned and I like to play that in the UHD standard w/o resorting to tricks.
As mentioned in my last post, anyone who can edit stutter free HD should be able to do so in UHD using shadow files.
No new BR optical drive needed.
