H.265 encoding technology

[wildwestgoh]

As topic stated, it's a new encoding technology that recently got approved, file size just get smaller for the same quality.
But, yes... there's always a "but", has anyone tested it?
1. Does it really get smaller without compromising the quality?
This probably needs some people to do some sample encoding.
2. Does it support 10-bit encoding?
Needs someone to do the sample obviously.

Discussion is open.

[kitamesume]

1. yes it does, it does so by making it more complex to decode, meaning it takes more processing power to do so.
2. yes it does, its works similarly to the older H.264 aside from it's more refined algorithms, expect H.265 10bit to be much more taxing.

its more like this : H.264 8bit < H.264 10bit =< H.265 8bit < H.265 10bit

I'm starting to be thankful that I bought a laptop with an i7. Because fuck you anime community, fuck you. Stop jumping on every new piece of tech you can.

[wildwestgoh]

I don't think it require until i7 to decode it, i3 with integrated graphics is plentiful enough for current technology, those whom still using Pentium 4, Core Duo or even earlier Core 2 series should upgrade, well... it's getting cheaper anyway.

Who's releasing stuff in H.265 already?

[Saras]

Not yet. But it's coming and you know it.

[vuzedome]

It has to prove itself to be better overall, not just partly, before mainstream pick up among the fansubs.

[kitamesume]

^it already proved itself worth it, theres already drafts in wikipedia(if you deem that legit) that leads to it being much more superior than H.264

note worthy quotes:

Two approaches for standardizing enhanced compression technology were considered: either creating a new standard or creating extensions of H.264/MPEG-4 AVC.[9] The project had tentative names H.265 and H.NGVC (Next-generation Video Coding), and was a major part of the work of VCEG until its evolution into the HEVC joint project with MPEG in 2010.

The preliminary requirements for NGVC was the capability to have a bit rate reduction of 50% at the same subjective image quality compared to the H.264/MPEG-4 AVC High profile and computational complexity ranging from 1/2 to 3 times that of the High profile.[11] NGVC would be able to provide 25% bit rate reduction along with 50% reduction in complexity at the same perceived video quality as the High profile, or to provide greater bit rate reduction with somewhat higher complexity.

On February 29, 2012, at the 2012 Mobile World Congress, Qualcomm demonstrated a HEVC decoder running on an Android tablet,with a Qualcomm Snapdragon S4 dual-core processor running at 1.5GHz, showing H.264/MPEG-4 AVC and HEVC versions of the same video content playing side by side.[29] In this demonstration HEVC showed almost a 50% bit rate reduction compared with H.264/MPEG-4 AVC.

to point out, there seems to be specific techniques to even result with a reduction of both bitrate and decode complexity, meaning a H.265 of the same quality would both be smaller and easier to decode.

I read an article (without source) that it's not heavier in decoding than h.264 but encoding takes the toll? Is that true?

[kitamesume]

possibly true but the decoding weight depends on how it was encoded, they managed to boost the decode efficiency at best so it wouldn't be a surprise if it did boost encode toll.

I rather like that anime encoding gets better rather than sticks with say 700mb DiVX releases. Just because some people go out and buy fixed hardware devices doesn't mean everyone else should have to deal releases only the set top boxes can play.

this i can agree, although i wouldn't mind people still creating old encodes but having such as an "only option" is kind of irritating, i mean i still see such a thing as either "raws" or "divx/avi".

[halfelite]

You can test it now with the reference encoder/decoder

But its not much use yet.

mehh... i'll   just wait for h.297   and ultramegaHD.... :/

Since you're already waiting, why not just wait for the holodeck?

Unless you're encoding it's not like you'll have to do anything on your end. If sub groups opt to release stuff in the more efficient format would you go outta your way to avoid them?

In any case, no anime production company is going to increase the resolution of their source material if fan groups adopt h.265 anyway. You'll still be free to get 720p stuff for awhile now, I'm sure.

[kitamesume]

more like 720P is the standard now a days, 1080P being the higher end and 1440P or 4K being the niche section.

no matter what encode type is developed, unless 1080P(or something higher) becomes standard, 720P will remain as the main choice of resolution for most encodes.

I was thinking of anime in particular. Whether a higher resolution encode exists is immaterial if no one produces higher resolution anime to take advantage of it. Well other than pointless upscales anyway.

I won't hold my breath for anime studios to produce stuff at 4k anytime soon at least.

[megido-rev.M]

4K is way overkill, at this time anyway.

Whoops, I meant for anime.

[vuzedome]

We'll need some very good upsampling filters for that.
