    lower bitrate == lower quality when using the same compression algorithms.

    most streaming services are using h.265, same as 4k blu ray, but at substantially lower bitrates

    streaming dolby vision profiles are also gimped considerably compared to blu-ray dolby vision

      Doubling down on the misinformation, I see. H.265 is a high-efficiency codec, or in other words a better compression standard. Not a static compression level. This is why when you convert media there’s an input for quality, even when using HEVC. And you can absolutely stream the same Dolby Vision profile as a Blu-ray with single track double layer.

      You’re still conflating digital medium with streaming services.

        i am more than well aware of all of this. nothing i said is misinformation. same algorithm, different settings. the primary means by which you reduce bitrate with h.265 is by reducing the quality setting. there is no magical way to cut your bitrate by 75% using the same compression algorithm without sacrificing quality. no commercial streaming service is offering video at the same quality level as a 4k blu-ray.

        few streaming boxes even support dolby vision profile 7, and no commercial streaming service offers it. so saying you can get it through a streaming service is actual misinformation.

        i have literally been doing this shit for 20 years

          Your entire presupposition that Blu-ray quality is better than streaming quality by default is misinformation, and I’ve already explained why.

          no commercial streaming service is offering video at the same quality level as a 4k blu-ray.

          What does that have to do with digital media?

          This is also demonstrably untrue if you take 5 seconds to research self-hosted streaming services.

          few streaming boxes even support dolby vision profile 7, and no commercial streaming service offers it

          Plex on Nvidia Shield. EZPZ.

          there is no magical way to cut your bitrate by 75% using the same compression algorithm without sacrificing quality

          I never said anything in contradiction to this. I don’t know who you’re shadow-boxing.

            OK i see the problem. you’re hung up on the fact that i said “streaming” without specifying commercial streaming services.

            however, my context should have been made clear by the fact that i was talking about ripping blu-rays to my fucking NAS, where they get streamed from.

            i’m saying “you don’t get the same quality from streaming services as a blu ray”. does that make you happier?

              Yup, words matter. I’m not saying this to be snarky or pedantic, I just don’t want anyone to think that they’re getting something inherently inferior if they want to go digital.

              however, my context should have been made clear by the fact that i was talking about ripping blu-rays to my fucking NAS, where they get streamed from

              It’s also really ironic you’d say this, because I’ve seen you completely ignore the original context in my thread on another post and could provide it as an example.

                scroll up. my very first comment, which is the top level comment in this thread, makes it pretty damn clear.

                read the whole context before you go off half-cocked and accuse people of spreading misinformation when they aren’t.

                  I’ll do whatever the fuck I want. Thanks.

                  Start choosing your words more carefully and it wouldn’t be an issue. Your original comment says nothing about streaming and your follow up comment doesn’t clarify anything:

                  blu-rays are often as cheap or cheaper than “digital copies”, and ripping them to my NAS is pretty trivial these days thanks to makemkv. the best part is, uncle jeff cannot legally break into your house and take back the disc just because of some petty rights issue.

                  4k streaming is also way lower quality than a 4k blu-ray

                  I know how a NAS works, but other people might not or possibly even mistake you to mean you transfer media to another machine for viewing. Additionally, I didn’t have any evidence to speculate that you knew there was a tangential reason for the quality disparity despite your comment being easily misconstrued.

                  My very first comment in this thread laid out the correct details you missed and you still debated it as if I said something incorrect. So much for 20 years of experience.

                  Some people…

                    let’s think for 5 minutes here.

                    I know how a NAS works, but other people might not or possibly even mistake you to mean you transfer media to another machine for viewing.

                    I meant what I said. If you interpreted this incorrectly, that is your problem. stop trying to pretend someone else doesn’t know what a NAS is, they are perfectly capable of looking up words they don’t mean. me using a word someone else does not know is not misinformation on my part, it is ignorance on theirs.

                    learn to comprehend the whole conversation, don’t reply to individual comments like they exist in a vacuum. language doesn’t work if you interpret everything hyper-literally. do you fall apart when people use euphemisms or turns of phrase? because those are far more vague than anything i said.

                    maybe most importantly though, don’t be an absolute dick to people when you ask for clarification.
