10 bit color spectrum is the best thing to happen to anime since moe and cgdct
other than that i have no actual complaints other than it being proprietary

Educate yourself. 10bit only means smaller file sizes.

Relevant only if youtube or the anime cartel decides to adopt it.

how is that not the best thing with moving to a new codec

Which it won't be considering the outrageous way HEVC is licensed. It will still probably end up on newer Blu-ray iterations, though.

It also means better gradients.

is yt h.265 yet?

h264 is completely free software

Is that what RealMedia format used to do? I remember downloading 30MB episodes of Bleach over a 56k connection and it looking pretty decent.

h.265 requires you to pay to two organizations

does haswell have HW accel for it?

Not patent free yet.

>using a video format which wants 0.5% of your entire revenue

top lel
also hardware resources are more valuable than bandwidth right now.

Patent royalties are no concern of end user. Nvidia/AMD/Intel already pays for it

Well, it's a mostly a question of relevancy. h264 became relevant because it was used by the blu-ray standard and by streaming sites like youtube. It also has very reasonable licensing. With the way the h.265 licensing is going, it's going to be difficult for it to gain any sort of ground in the online space.

Free software distributors don't pay MPEG LA, so you cannot legally use ffmpeg and such in certain countries where software patents are valid.

yeah no you fucking imbecile

H.264 isn't even software, it's just a spec. Implementations of it may or may not be free software, but even if it is, it's still subject to patent restrictions.

Brilliant. Love the smaller file sizes despite having more than enough space. Bandwidth is a necessary consideration for me living in the boonies of Iowa with a 1MB down connection, too.

There's another free codec coming along I think I heard about, but heck I'm fine with it. HEVC runs fine on my machine because I can afford new stuff.

Distributions can't include it, but you can legally use ffmpeg yourself as an end user because royalties don't apply to them. Worry only if you are planning to open a streaming site or professionally selling your HEVC encoded work.

Apple adopted HEVC, chunk of streaming industry will adopt it as well.

It takes fucking FOREVER to encode.
Otherwise, I don't really see any downsides, aside from its non-free license.

>Educate yourself
>Is un-educated
Wow made me think

>watching 10 bit color spectrum on a 8bit monitor

EXPLAIN

Let me hold your hand for a second here.
How many permutations in 10 bits?
How many permutations in 8 bits?
What do the bits represent?

We know DVD is 20+ years old, so the patents of MPEG-2 video(H.262) should be expired now along with AC3 and DTS.

Apple's support for it is waning and everyone else, including youtube, amazon and netflix, is on the AOMedia train. AOMedia exists because pretty much everyone in the industry is pissed off by the h.265 licensing. HEVC is not going to gain ground in the digital space. Only place I can see it being used is in Blu-ray discs and DTV boxes. Even the DTV space is shaky since BBC is on board as well.

10bit in compression formats don't refer to each color channel having 10bit range. It refers to each color being encoded into a 10bit value (which includes all channels).

> Apple adopted HEVC, chunk of streaming industry will adopt it as well.
Everyone except Apple went for AV1.

Different color spaces. Video uses YCbCr and the display uses RGB. High bit deptb does better conversion.

while on a technical level sure, but what you can notice with the visible eye, it makes no difference.

Any time you see banding in anime or some other shit it is almost entirely due to low bitrate for video

256-256-256 become 1024-1024-1024

AV1 is nice and advanced tech but won't be remotely usable until 2020. Maybe even later for mobile till hardware AV1 decoders in chips arrive, consider HEVC wasn't much usable until 2015. Those streaming oriented companies won't pass Apple market, it's size would worth the HEVC investment even for 3-4 years of use.

>due to low bitrate video
You know full well that isn't the full story.

neither is the text you quoted

>is almost entirely

Even 40 mbps commercial BluRay adds grain in the background to avoid the banding. Usual 16-235 scale is simply not enough for smooth gradients.

>patents expiring
haHAA im 12 btw

It's really great. Episodes came from 800 MB to 400 MB.

If you have the hardware to push it, then sure.

But not all devices, namely some set top boxes, smart tvs, and some phones, don't have the ability to decode some 1080p streams, and mostly all 4K streams without some lag.

It's a future codec, but current hardware holds it back.

Apple has no hold if it doesn't have content to utilize that capability. Pretty much the only thing that apple is using that h.265 hardware for is facetime. Streaming providers, on the other hand, would probably prefer sticking with h.264 for now instead of paying the expensive h.265 fee for five years and then suddenly converting all of their content to AV1. The fee is not worth it, especially now since there's barely any 4k content to justify the expense. By 2020, you'd probably have enough 4k content to start using more advanced codecs.

Mfw i see 720/1080p hevc shit and filesize is same as old dvd rips i have.

it depends, there are a lot of cheap boxes that have HEVC hardware decoding.
The discontinued Nexus Player for instance, and I assume the new Google player that is in the works.
My phone and tablet do it just fine too.

The Nexus Player SORTA works. Plex loves to crash when attempting HVEC direct play on the Nexus Player.

Pile of junk on top of a patents minefield. That's why nobody is interested in contributing to x265 and why x264 still produces better results at the same bitrate.

AV1 bitstream freeze SOON FOR REAL THIS TIME, my fellow video compression enthusiasts.

I dropped my Nexus Player for the Nvidia shield, the Nexus Player has really weak wifi even on 5ghz.

>random bullshit out of my ass
Bitstream will be frozen in December. Hardware support will be there next year. Encoders will mature quickly by the end of next year. There are quite literal billions at stake for streaming services and all the major hardware vendors are in it since the start.

Dithering.

I would but I can't justify dropping $200 for an android set top box that more or less does the same exact thing with a tiny bit less of errors.

To be fair I do like going back and grabbing HEVC shit to "clean up" space on my drives, but you have to be careful you get the right shit or you end up dropping quality hard from your 264 stuff. Keeps me busy I guess.

Any weeb distributes his fansub in VP9?

I was going to buy a mi box or something but I just thought "fuck it, I don't want any issues anymore".
The advantage is it can host a plex server and transcode quite well, my NAS is too weak to transcode.

I know if I did it all again I could have bought a cheaper android TV and a more expensive NAS but I can only go forward.

>Pretty much the only thing that apple is using that h.265 hardware
You haven't heard the news? They enabled HEVC in safari and general app use in iOS 11 and High Sierra, that new 4k Apple TV also enables supports it for 4k content, new 4k HDR movies are in HEVC in itunes.
developer.apple.com/videos/play/wwdc2017/503/

Netflix and Amazon already uses HEVC for their 4k rollout, they will utilize it for Apple too. Don't be surprised if other backend companies (CDNs etc) announce their HEVC friendly services soon

Remind me how many years it took for x264 and x265 to mature? In their presentation they specifically said it's a "soft" freeze and that may mean anything in between including bugfixes or adding new features. AV1 will mature faster but you're naively optimistic if it would be passable for general consumption until 2020. At best case you get youtube support in 2019.

No, why the fuck would they bother?

topkek

I converted my old PC into a media server. The benefit being it has enough power to transcode three streams, and I can shove nearly as many drives as I want to inside it. Currently hosting 12 TBs.

It just took longer time, quality almost identical, I shaved almost half storage space (10 tb to 4 something like 6 hdd) from my old DVD and bluray but took like months+ to convert, I'm not bother with it anymore I get a new hard drive kek.

/thread

this is obviously great for flexibility, expandability and always having enough processing power to do what you want, but I'd be wondering about how much it would affect my electricity bill having a built x86 NAS instead of a power efficient store-bought unit.

better jacobians

patents do expire. what are you referring to?

Wuh? 10 Bit is only useful for color accuracy, which is pretty much useless for anime.

h.264 = your bandwidth gets raped
h.265 = your CPU gets raped

It's vp9 which is better

I am on Ivy Bridge, and 10 bit HEVC runs fine with no stutter.

Smaller files = better.
With hardware generally strong enough to handle it on both ends it's a clear win to me.

does it rape your cpu like 265?

I love it, I may re-rip my DVDs 'n shit to put em in HEVC instead of h.264

Depends on hardware support, so pretty much the same as h265

>he doesn't own a 10bit monitor

With hardware decoding it won't use much processing power at all.

Old hardware won't get hardware decoding although GPU decoding is probably possible.

better laplacians

Soon to be deprecated.
AV1 (releasing at the end of the year) will be technically superior and with Google adding it to youtube and android, Mozilla supporting it in Firefox, Microsoft in Windows, Netflix, Amazon, Hulu and hardware manufacturers (Intel, AMD, ARM, Nvidia) on board it will dominate HEVC.

Not a problem, just buy new hardware ;)

Yeah fuck that.

A fucking 1080p anime ep that's 20 minutes long is half a gig

A porn vid that's 40 minutes is 4 gig or more

Will this new codec make the file size smaller but keep the exact quality, pixel by pixel?

How on Earth do you watch non-dithered HDR10 material?

The only way I have found out is to plug in a drive to the television (LG OLED) itself.

PS4 Pro dithers or HDR flatout works terribly.
PC, nVidia and Windows can't get it working since Creators Update.

How the fuck do you watch HDR10 properly? I tried test sample in "Movies & TV" application that is supposed to support HDR but it just dithers the test sample to 8bit.

And mpc-hc with madVR looks really fucking bad in HDR, like half the colors are missing or incredibly burned/bright.

>AV1 (releasing at the end of the year)
I feel I've been reading this for a couple of years now

Dithering.

>AV1 bitstream freeze
the what

its not about can we see it, it's about banding.
10bit nearly eliminates it from human perception, and yes, when you have a large area of a slight gradient compressed the banding is obvious, but even on an 8 bit screen, if you have more color to pull from the banding is less if not unnoticeable allowing for smaller file sizes while retaining much of the quality.

I will say you are right on can we really perceive it though, most people even artists who work in color have a real hard fucking time seeing a 1 point difference in color, what is going to happen when there are 3 more colors in between said points to pull from?

At the same quality level, H.265 is about half the filesize of H.264. Which itself is much better than previous codecs.

Obviously you will lose some pixels converting because these are all lossy formats. The main way they achieve such small filesizes is by discarding some information in ways that are imperceptible to the human eye.

At higher compression rates you will lose a bit of detail, but in exchange you can get ridiculously small file sizes and the quality isn't that much worse. H.265 in particular focuses on removing a lot of weird artifacts that digital compression is notorious for, like weird color ripples and blockiness. There's not really any reason to be using multiple gigabytes for videos less than an hour.

Anyone? I'd really love to have working HDR10 with games and films in Windows.

>vp9 which is better

>laughing_girls.flif

>RealMedia

That shit blew me the fuck away back in the day.

I watched some anime in 10bit a week ago and couldn't tell the difference

Was I memed to?

Thoughts on the codec? Pretty good. Powerful, extensible, efficient.
Thoughts on the patent hell? Awful. It's the reason it will barely be used for UHD blu ray and for some streaming services that suck the MPEG dick.
Thoughts on the encoders? They all suck. Bad. Software or hardware. And i'm including x265.

>is yt h.265 yet?
No, and it will not. It's currently VP9 for PC and modern phones, h.264 for old phones and assorted devices, with AV1 replacing VP9 starting next year.

>I watched some anime
I hear suicide is a good cure for that.

>That's why nobody is interested in contributing to x265 and why x264 still produces better results at the same bitrate.
Right, I'm sure that x264 being written by weebs and x265 by pajeets has nothing to do with one being infinitely better than the other. It's totally the codec's fault.

No, hw accel on Intel started with Broadwell.

Try 4k 30/60fps video (the only content worth using hevc for) and report back.

negligible unless running 24/7 and even then idle should be under 100 watts.

the 10bit meme was truly a fucking mistake

Any android box that can play 4k, HEVC, HDR etc, besides the Shield?, $200 seems like a lot for a tv box

I have the 1080p Seasons 1-11 episodes encoded in HEVC, and damn they are small file sizes. Like 90megs per episodes.

Hey, nice baito

AV1 > h265 > vp9 > h264 > vp8
