Personally Iâm hoping Microsoftâs project silica takes off and replaces blurays. Having worked in a movie theater, I can tell you the files on blurays arenât the same ones that get played at a theater. Same resolution and framerate (probably), but dramatically higher bit depth (though I dunno if you could tell the difference normally). This could be a way of releasing master quality recordings for home use.
IDK what Project Silica is, but I donât want Microsoft in charge of the future of physical media. That experimental multi terabyte disc standard should be where physical media goes next.
I mean, iirc, Blu-ray was originally Sonyâs thing; VHS was JVC. Most formats were something a company came up with and then became so widely used that people thought they just sprung out of the ether.
The multi-terabyte disc thing sounds neat. Project Silica is the sci-fi crystal data cube thing, where they vaporize tiny bits of crystal with a laser to write data, and then read it back with a laser as well. I like the idea of project silica more just because âmuh sci-fi data cubesâ, but discs capable of holding terabytes of storage would be sweet.
A lot more. A 4k disc has a bitrate of 128Mbps. Right now there are HDMI cables that can push 8Gbps and can be bought at Walmart.
The returns definitely are diminishing though. I am really struggling to see differences between 4k and 8k on an 80" screen at 6ft away â granted, I was looking at a floor model.
I think the real value is in archival though. If you have the true copy then youâll know youâre not suffering any generational loss whenever you transcode the file. Itâd also be nice to get the IMAX versions of movies with no loss of detail.
Iâm not sure physical home media has enough life left in it to attempt to change players/formats again, not for that small of a (noticable by end user) change. Thatâs the sad truth.
Sorry I mean to say how much more meaningful data? Like with modern and upcoming common TV tech would there be much noticable difference?
Unfortunately physical home media is dying. I hate it but itâs true. I donât think it has enough life left in it to have another format/player change and it certainly wouldnât be worth trying for the limited return.
Afaik HDMI hasnât been a bottleneck for movies in a long time. The 4k masters I had when I was working at a theater averaged around 100-200 megabits per second, which translated into movies that averaged around 200-300gb. Larger WORM (write-once, read-many) storage would potentially allow for master quality recordings to be produced for cinemaphiles.
While you might think there isnât enough demand for it, you might also not be aware that movies from back-catalogs come on hard drives. When your company has an outing to a movie theater where you all watch Elf together, that movie was likely originally on a hard drive (afaik only new releases get the luxury of being transferred via satellite). Instead of shipping spinning drives, they could ship data crystals (project silica) instead. This would have the side effect of potentially making the crystals reasonably priced for collectors and enthusiasts, allowing them to get the master quality version of their favorite movie(s).
For archival purposes, you want a lossless master so that new copies can be made from the original using any new codec that is later developed, whether that codec prioritizes quality, file size/bitrate, encoding/decoding cost, certain hardware optimizations, etc.
That way a 1995 film can be shown using a 2035 codec when the time is right, rather than relying on a 2035 encoding of a 2020 encoding of a 2000 digitization of a 1995 analog master.
though I dunno if you could tell the difference normally
yeah, that. given the infinitesimal amount of people with the equipment and eyes to discern that difference, i doubt that will be a financially viable business. already most people are fine with streaming which is worse quality than 4k discs.

I mean a 4k blurays can already hold like 100GB of data. How much more can you push through home connections like HDMI?

I suppose, but I was just answering your question.
Your hardware needs to support this though and itâs typically higher end hardware that can do this reliably
Whatâs wrong with a harddrive?
Nothing really. But I doubt theyâd ship a whole hard drive for one movie.
Some 8k things are barely noticeable and some are MAGNIFICENT. The best ones Iâve seen are nature shit. THE FUR
True. Especially in theaters
The most recent HDMI versions are limited to 48Gbit/s, so you could fit almost 17s of a movie on a 100GB disk!

On a Blu-ray 1:1 remux, I definitely notice choppy gradients on my Sony bravia, and Iâm not much of a snob for video as long as itâs HD.
