My Blu-ray collection doesn't look appreciably brighter or more lifelike than current high-quality streaming service fare. I'm sure the resolution is better w/Blu-ray, but is it a classic case of a distinction w/out a difference?
because quite simply, streams vary greatly in their compression, and the less compression, the better they look. Every streaming service has to compress, just like cable TV channels have to compress. So if you are watching a 4K stream, it all depends simplistically on how many bits per second you are getting. And a stream will never be the full bits per second you will get from an original disk, at least in my experience. I will say that the 4K bluray from a disk source is far and away the best home video I've ever seen. I watched Vertigo, which I've never seen in a theater, but which I've seen many times, and it was a new experience in 4K.
I have only a few 4K UHD Blu-ray discs and they DO look sharper on my 4K capable TV vs 4K from streaming services like AppleTV or Netflix.
Interestingly, I also find that over the air local HDTV broadcasts are sharper than the same content coming through our Cable TV service. For example, if I'm watching a live sporting event like NFL football the over the air broadcasts are sharper than the same event coming over Cable TV. They're both good, but over the air is a bit sharper. But I can't rewind and instant-replay over the air like I can with Cable TV ;-)
A nice article about why ota is less compressed than cable.
using an antenna provides the best picture quality. Now of course, this is all relative...there are all these side channels now, like 7.2, 7.3, etc. and many of those are bit starved and look terrible. But a major station like a network will likely look best over the air.
I get all my rentals from Netflix in Blu-ray format if available. There is a very noticeable improvement over regular DVD as well as all the streaming I have done. Amazon Prime and Netflix have been my main sources for streaming. I will say their steaming quality has improved over the years.
the enormous size of the bits?
That depends on you internet speed. Netflix streams 1080p (Blu-ray equivalent) at about 25 Mbps. I don't know about other services. That's in the ballpark of most Blu-ray discs. Their 4k is only about 15 Mbps.
"According to ReviewGeek, the blu-ray disk outperforms streaming by 3-5x. Streaming promises 4k viewing but the maximum quality is only 25 megabits per second while blu-ray plays at 82-128 megabits per second."
I don't doubt those numbers, but money probably plays a role. Not all discs or streaming are done at max bit rate. Netflix has stated that it was cutting back on bit rates, other sources may not be doing that. I just know what the gear tells me.
When my Oppo goes to that great HT in the sky, I'll get a 4k player so I can see what my TV can really do. :-)
No idea. It's in the info when they stream. I don't know if other sources do this too. They don't give the info. Maybe it takes too much bandwidth?
. . . I don't know how much compression is involved.
One of note is Zero Dark Thirty. The scenes of the raid on Bin Laden's house, in the dark, are better resolved on Blu Ray. Black crush, even on the trusty ol plazma, is quite noticeable whilst streaming.
I'm currently streaming Barry Lyndon and, while I don't have the Blu Ray to compare it to, my recollection of it on the big screen is of a brighter, richer, color palette.
On many others, the resolution and detail is striking and I'm guessing, improvement, if any, would be on the margins.
"E Burres Stigano?"
Probably a moot point when I watch my 14 year old 42" 720p Panasonic plasma at 12' away!
haven't been beaten. Soooo realistic.
Still using my 14 year old Panasonic plasma (50"). Still looks great to me.
I do really like it. It's the commercial/professional model and although only 720p does look great. I'm hoping it lasts a long time!
I had a Pioneer 1080 and loved it. Didn't want to risk moving it so a neighbor got gifted; he's still amazed.
Blu-ray looks noticeably better than 1080p streaming on my set, both in detail and colors. Sounds better too. Now 4K streaming is another story. I don't have a 4K disc player to compare. The best 4k streaming is better than 1080p Blu-ray. my guess is that 4k discs look better than 4k streaming. FWIW, Netflix cuts the bit rate way down on their 4k streaming.
