Blank 4K UHD Discs?

See https://forum.videohelp.com/threads/388243-BluRay-Player-with-BDXL-Support You will need to read through the above thread to find out which UHD Blu-ray players can play movies on BDXL media and the maximum amount of space that the movie can occupy on the disc

TLDR version:
Some UHD Blu-ray players can play UHD Blu-ray on BDXL media but others don't. Those that can are sometimes limited to movies that occupy up to 66GB, the first two layers on the disc.

Although BDXL media has sufficient capacity for UHD Blu-ray, the official UHD Blu-ray spec only covers pressed media, so UHD Blu-ray players are not required to read UHD Blu-ray movies on burned media.

Verbatim BDXL media can be found on Amazon but it isn't cheap. Some people get a few BDXL-RE discs to practice with since they are re-writable.

I think it can but maybe not reliably and maybe not if the movie occupies more than 60GB. If you want a definitive answer read through the thread I linked to.

Although I have that player, it is only used for playing original UHD Blu-ray discs, not copies. I'm not planning to burn any copies.

You can try doing that but the Sony-X700 can only play media files from USB, not complete discs, either as file-and-folder structures or ISO files. I don't recall if I tried playing any UHD video files with HDR or not. I mainly bought the Sony-X700 to play my collection of original UHD Blu-ray discs, Blu-ray discs, and DVDs.

yea man https://www.verbatim.com/subcat/optical-media/blu-ray/bd-r-dl/show-products/
are these videos you made with own 4k camcorder?

Don't listen to these guys, BDXL discs only work on BDXL players/recoders. Read the BD white paper, it answers all your questions.

The forum rules here are not the same as at blu-ray.com It's true that discussions involving pirated movies aren't allowed in this forum but as long as it is not obvious that the movies were obtained illegally, members can ask how to make a copy.

I have backed up a couple of my UHD Blu-ray discs as files to play on my computer now that Intel and Microsoft have removed the security features that made it possible to play them using the only method approved by the BDA.

The thread I linked to says otherwise. Some people are clearly able to burn copies of their movies to BDXL and play them on specific UHD Blu-ray players, although to be sure, not every UHD Blu-ray player.

this question wasn't about piracy, I only have experience with my own video I've shot on put on disc, i need to know so I can answer properly.

that means it doesn't work. Buying a triple layer disc only to use 2 layers to play on a specific player renders it unworkable, at $5 per disc, it's a much better, cheaper option to use BD-R 50.

BD-R DL is a cheaper option than BD-XL but 100GB BD-XL discs have 3 layers, so the first 2 layers hold about 66 GB, not 50 GB. Even if someone uses only 60GB for safety, that's still 20% more data than BD-R DL holds. Burned BD media doesn't support bitrates that are as high as what pressed discs support, but a little more storage could still be helpful for longer movies.
