Whatever happened to this? You'd think that most Chinese cartoons would be done on HEVC by now, but most of them are still on H.264. Why? Is it because of Daiz?
>>
Because it's still green. Hell, Daiz is using it for Ajin and it doesn't look any better.
>>
>>137661596
It doesn't have to look better. Compressing a bit without losing quality should be a huge deal. I haven't used ffmpeg in quite a while, so I don't know how long it takes to fully encode a video.
>>
Shameless self bump with TT's HEVC torrents mostly from >Doki.

THERE IS NOT A SINGLE ONE "HIGH EFFICIENT VIDEO" ENCODER FOR IT
>>
>>137662912
So, it's painfully slow?
Making pic related took quite a while on a 3570k OCd to 4.3GHz.
>>
>>137662912
Are you sure you understand the meaning of "high efficiency"?

H265 gives you a smaller file at the same quality and same bitrate. The trade-off is that it takes longer to encode, and older processors that do not have certain features can't decode it efficiently (specifically, special HEVC extensions that are now common on recent ARM/Intel/AMD chips). In those cases, the video player must fall back to software decoding which can make old chips heat up really fast.

If you're a consumer and H265 videos are consuming a lot of CPU power or just plain laggy, you need to buy a newer computer.

If you're an encoder and H265 is taking a long time to encode compared to H264, that's the whole fucking point of H265 and you still need to buy a better computer, or compile FFMPEG to use GPU assisted encoding.

For benchmarking, I have a GTX 760 and it takes me around 10 minutes to encode a 25 minute H265 video, but I usually do so when playing games at the same time to pass the time so eh.
>>
>>137663128
>>137663618
Means there is not a single person in anime business with the skills to encode x265 proficiently.
>>
I've never seen anything encoded with HEVC on nyaa.

I just download the S1 of OPM in x265 to compare against the x264 episodes I already have on my PC.
The episodes with both codecs look exactly the same, but the files encoded with x265 only have 1/6 of the size of the x264 files. How does this wizardry even work?
>>
>>137663618
>10 minutes to encode a 25 minute H265 video
Well shit. How does the output fare in comparison? I mean, what about quality and filesize compared to most H.264 encodes out there? ffmpeg's site here https://trac.ffmpeg.org/wiki/HWAccelIntro mention NVENC and I have a 970, which should do fine compared to your 670.
>>
>>137664042
There were some blurays going around, I think from Sally subs. There's also doki doing it, but then again, it's Doki.
>>
>>137664092
I've got some HEVC shit. philosophy raws uses it, and he(?) does a pretty solid job.

It does use a little bit more processing power, but it really isn't too much of a bother for my machine. I like the reduced file size.
>>
>>137661560
People saw what a shit show adopting hi10p was and are waiting for it to mature more.
>>
>>137661560
It's a pain in the ass to encode from what I understand, and takes longer than h264. The HEVC encodes I've seen (non-anime, granted) have almost all looked like ass, probably because the encoder wanted to go for the smallest possible size, and the fastest encode.
>>
>>137663618
>>137664042
I'm going to read a bit and reconfigure ffmpeg. BSS's Redline just finished being reencoded, but it took 3hours and about 36 minutes with normal presets and a CRF of 17(I really don't know what I'm doing). The normal present only had a 28% file decrease.

Lossless if anyone wants that.

I've got a really nice copy of Only God Forgives in HEVC.

It's small, but it looks excellent even compared to my Blu-Ray copy.
>>
>>137664383
There's the slightest of smudging on the HEVC, but you'd have to have a hawk's eyes to see that in motion

And the second one looks better in every way than the source.
>>
>>137664042
>1/6

x265 isn't nowhere near enough.

Combine with 10bit if you want such results.
>>
>>137664423
Nice. Good movie too. I had some good ones of the Die Hard series that were in 720p, but beyond that, most that I sampled looked crappy. The edges would be softened and the faces of people would have a weird smudged/airbrushed effect due to trying to squash grain/noise. Or they would be pixelated like shitty Youtube videos. I sampled a couple of Battlestar Galactica and The Wire ones that were just plain hideous.

It's a thing I'm definitely going to watch for in the future as it becomes more common, but right now most of it doesn't look nearly as good as it could, simply because a lot of computers can't handle it, or encoders compress too far.
>>
>>137664630
Yeah, I've gotten my mom some tv shows, and they've all looked like ass when I go to sample them, but whatever she can't tell the difference lmao. Still, I don't want her to have like a gorillion GB storage dedicated to shows because of my videophile tendencies.

I think if an encoder actually takes the time to work on the release it will come out looking nice, but most people just crank it through for e-peen most fastest/downloads
>>
Holy fuck, the encoding with this shit is slow as fuck, you need a dual Xeon to do something at a reasonable speed and quality.
>>
>>137665170
See >>137664302 and it's not even on the slow presets.
>>
>>137661560
There's little to no difference between h.265 and h264 with hi10p with almost the same size. And some people still complain about 10 nits, from hevc would just explode.
>>
>>137665509
>from hevc would just explode
I really want this. Besides aren't GPUs supporting HEVC nowadays?
>>
INITIATE THE SUMMONING RITUAL
>>
>>137666300
H-here goes.
>>
>>137663618
A little late on this, but I went ahead and configured ffmpeg for nvenc. I used their example with a slow preset and a crf of 17 putting out a 321MB video. It looks worse than the one done by the CPU, but it was done marginally faster. Also, the storage savings were pretty shit, we're talking 321MB vs 343MB.
>>
>>137667420
The only anime I think were the storage saving it gives matters would be 4k anime if it ever comes.
>>
>>137667523
I'm ready for UHD Redline.

Daiz you bastard.
Why doesn't somebody just shoot him?

People release secondhand h265 encode turds on kickass and poo-in-the-loo swarm to it.
>>
>>137669346
>file sizes are pretty small
>quality is alright, watchable
I dont see the problem here?
>>
>>137669546
because making an encode of an encode always decreases quality, no matter how good the codec.
>>
>>137665991
Only the latest models from Nvidia. No idea about AMD or how well this works
>>
>>137672561
Intel as well, though only 8bit.
>>
>>137664383
kills detail, dark area is banded
>>
>>137664302
did you use 10bit hevc?
>>
Last I checked, even the 970 and 980 don't have hardware decode for h265. Though oddly enough, the 960 does.

Either way, it's too hard to encode and decode right now to be a decent replacement for what we currently use. If 10bit pissed a bunch of people off, h265 would make files totally unplayable to some people.
>>
>>137673017
>oddly
970 and 980 are using older chips
>>
>>137673071
Fair enough, I just find it funny that the more powerful cards don't have a feature the 960 has.
>>
>>137661560
>Whatever happened to this
Glad that this shit died. Bad enough, that FLAC is still a fucking thing. No one will hear any difference between mp3 and FLAC. But shit man, lets encode in loseless because fuck it. Fucking dumbass kids.
>>
H.265 is responsible for climate change
>>
>>137661560
Daiz didn't get paid to push HEVC, that's why no fansubber care.
>>
>>137664383
In all honesty, i don't see a notable difference. So i don't really give a shit about h.265.
>>
>>137673144
What fansubbers? Fansubbing is pretty much dead, that's why Daiz can't push it.
>>
>>137673199
Why doesn't Crunchy push it? Lower bandwidth would save them money.
>>
if Daiz pushed it too hard he'd be making it obvious Nvidia paid him to shill it. I mean shit there are people with toasters still complaining about h264, and now he wants to push something that was designed for Nvidia's underwhelming, overpriced 900 line?

I guess Malyasian cartoons isn't high on the bribe list though. They blow all their money bribing game developers to use Nvidia Gameworks™ The Way It's Meant To Be Artificially Gimped
>>
>>137673217
Because compatibility.
>>
>>137673217
Crunchy ain't fansubbers and have to care about their customers being able to play their videos.
>>
>>137673199
Be sure that if Daiz got his money, HEVC would be all around even if he had to start new re-encoding groups.
>>
>>137673251
You are aware that Daiz controlling the fansub scene is just a retarded meme, right?
>>
>>137673251
Re-encoding groups use shit with more compatibility, not less.
There's no other reason to re-encode.
>>
The encoding is much slower and the quality basically the same.
This codec is in danger to be a big fail, or already is.
>>
>>137673248
>>137673241
They could be offering both. They're also offering three different resolutions for h264.
A ten year old computer can play h265 in 1280x720 and the playback is controlled from Crunchy's side.
>>
>>137673248
everything goes through their shitty flash player nonetheless, so their customers wouldn't care for shit since they are already blind paying for such quality
>>
>>137673295
It's not really intended for current content, more to get 4K a decent filesize.
Ergo there isn't really much point in encoding anime in it in the first place, since it's 720->1080 master.
>>
>>137673310
A ten year old computer has problems with 720p in h264 if there are effects like Karaoke-shit added.
>>
>>137673287
>You are aware that Daiz controlling the fansub scene is just a retarded meme, right?
I didn't say he control it, just that Daiz is proven shill.

>>137673291
Re-encode was a wrong word. But even then there were groups who re-encoded 10bit to 10bit with smaller size.
What I meant was commie-like group who just rip subtitles and encode the video.
>>
Daiz is actually using H.265 already, Underwater's Ajin is encoded in it
>>
>>137673337
I never tested on 4k but i doubt it make lots of difference. All the trials i made with the h265 had basically the same quality/size ratio of the h264-hi10. And it was much slower. Plus it require more resources to play as well, and is less compatible.
Is simply not worth the effort.
>>
>>137673353
Crunchy doesn't do karaoke.
My brand new computer had trouble with typesetting.
>>
>>137673538
Karaoke was just an example for many sorts effects.
>>
>>137673126

h265 is actually a good (once it matures) thing though. 4K will depend on it
>>
>>137673217
>crunchy
>giving a fuck about quality or anything
They don't care at all and even if it made shit cheaper, they still probably wouldn't care.
>>
who the hell cares about file size
hevc is worthless for now
there's not a single example of 265 looking any better than 264, even with shit people spent days encoding
>>
>>137673718
Ah, okay. Well, 4k isn't that popular yet. We'll see how it develops. Still think that FLAC is unnecessary, though.
>>
HEVC would be a good idea if we had 4k anime. But most are still mastered below 1080p, so that won't happen for a very long time.
>>
>>137673972
>Still think that FLAC is unnecessary, though.
That's probably because you don't archive. If you are going to make a release with the best video quality you can get it at, you may as well add lossless audio to it as well for archiving purposes. The extra data shouldn't even phase you.
