Talk:Ultra HD Blu-ray

Compared to what ?
The article says: "Ultra HD Blu-ray supports 4K UHD (3840x2160 resolution) video at frame rates up to 60 frames per second,[2] encoded using High Efficiency Video Coding.[2] The discs support both high dynamic range by increasing the color depth to 10-bit per color and a greater color gamut by using the Rec. 2020 color space".

 * Versus Blu-ray. I'll clarify it in the article. &mdash;ajf (talk) 17:38, 24 March 2017 (UTC)

Physical differences between this and regular blu-ray?
"Ultra HD" is incompatible with existing blu ray drives, so there is presumably a physical difference on their construction (optics, tolerance) vs. simply a marketing gimmick. What is it? Silenceisgod (talk) 14:04, 13 March 2018 (UTC)

physical or video quality difference or backward compatibility issue? the disc is in round shape just as any other disc dvd blu ray or audio cd,its just that you need uhd tv or  uhd player to play uhd disc thats it.4k or whatever .it wont play on regular dvd player. — Preceding unsigned comment added by 103.39.81.132 (talk) 07:35, 2 January 2019 (UTC)

BD-XL?
Does the storage media use BDXL ? — Preceding unsigned comment added by 2001:980:1241:FE:F1AF:8E75:B5ED:804B (talk) 06:45, 14 September 2018 (UTC)


 * Apparently not. A three layer 4k Blu-ray disk (i.e. 100GB) cannot be read by a Blu-ray disc drive that reads and writes BDXL 100GB discs. 81.153.20.205 (talk) 17:08, 15 April 2023 (UTC)

Merge with Blu-ray?
In technical and physical terms, the Ultra-HD Blu-ray ultimately is either a traditional 2 layers BD-ROM, a 3-layers BDXL or the equivalent of a 3-layers BDXL with just two layers used. I suggest to merge this page with the Blu-ray page not to give the impression that a new physical disc specification, different from Blu-ray, was created.—79.54.48.13 (talk) 16:35, 24 November 2019 (UTC)
 * , the Blu-ray page is already loaded and should probably have it's AV format part split.
 * Users looking for UHD BD want just that, not land in the middle of an all-encompassing multi-generation essay. Plus for all practical purpose, a UHD BD does not read on a BD player, just like a new disc format.
 * Instead add your physical disc clarifications, and links to and from related pages. --Musaran (talk) 18:24, 14 February 2020 (UTC)
 * At the very least, the linking between the two articles should be improved, such as the question above about the relationship between UHD and BDXL, which doesn't appear to be answered in either article. Perhaps the "AV format" section of the article could be spun off into its own article, and then this one merged there, referencing back to the "parent" article for the hardware details? - IMSoP (talk) 19:26, 29 May 2020 (UTC)
 * ✅, this is not a separate format from regular Blu-Ray, the technology is the same. All that differs is the encoded formats on the disk. BD association marketing jazz is not a sufficient reason to split this page from the rest of the Blu-ray format. Ergzay (talk) 03:51, 7 December 2020 (UTC)
 * , UHD Blu-rays have updated standards, including additional, severe restrictions with DRM as well as restrictions enforced by licensing. For example, there is no longer ANY officially supported way to play UHD Blu-ray video on PC with modern hardware and current software versions. There are significant changes that warrant this being its own article. Also the Blu-ray article is extremely bloated as well (and should probably be split up, however that's another discussion). —danhash (talk) 15:31, 29 November 2023 (UTC)

Sales and reception
Although the sales of dedicated Ultra Blu-Ray players have been modest, the format is also supported by a number of game consoles (Xbox One S, Xbox One X, Xbox Series S, Xbox Series X, and PlayStation 5) and sales of those consoles greatly exceed the number of dedicated players that have been sold. Sales figures for the discs (which are not given here) are likely to be more relevant measures of the format's success than player sales, as they would also capture information about how many of those game consoles are being used to watch Ultra HD Blu-Ray discs.

"Initial releases by movie studios and distributors" part
Should I make this part as a table?

This will have these columns: - Studio / Distributor name - Disc Title - Release Date - Other Notes

 * You obviously gave up on this but for posterity, absolutely not.WP:NOTDIR Thanks. — Smuckola(talk) 19:47, 14 September 2023 (UTC)

PS5 and 100GB discs
"Software made for the PlayStation 5 can use 100 GB UHD Blu-ray discs." Isn't the same true for Xbox Series X? —danhash (talk) 15:32, 29 November 2023 (UTC)
