Whatever happened to H.265? Is it still too resource heavy to convert entire libraries? Chinese cartoons are usually up to date with this stuff, but not even they are pushing it out.
>>53008612
Takes too long to encode so far.
5x time for 10% less size is not worth it.
>>53008655
That's a darn shame.
In this case, having more cores is definitely useful. How does something like a 5960x fare? I'd love to see comparisons.
My FX-8350 slows down a LOTTTTTTTTTT when using H265. I figured out really quick that it just wasn't worth it for H265 and for the long encoding time the image wasn't that much better.
I have shitty CPUs and this codec rapes my ass. We should all use VP9.

unless you're netflix or amazon in that case it is worth a lot
>>53008655
10% of 6TB is still 600GB. I could very much have 600GB more of Chinese cartoons or movies.

smaller file sizes are better if you plan to stream
Most internet companies are pushing an open license, royalty free format. Nobody wants to pay the video kike his tax.
>Whatever happened to H.265?
What do you mean?
UHD-TV-broadcasts, 4K-streaming and 4K-Blurays are using it in the Main-10bit-flavor. In Germany, 1080p DVB-T2 is using it, too.
Outside of STBs, most hw-decoders in the wild only support 8bit-decoding.
H265 is well on its way to world domination.
some P2P groups are using HEVC. It'll be another 8-10 years before the scene adopts it though.
>>53008612
It's definitely worth it. People claiming that it takes 5 times longer to encode for only a 10% size reduction are just plain doing it wrong, or encoding on a single-threaded toaster oven.
I try to torrent everything in x265 now, but it's still gaining adoption amongst encoders.
>>53008655
Try more like 50% savings
>>53010152
>jumping on a much slower torrent so that you can save a few hundred megabytes
seriously, how much space do you save on your chink cartoons ? less than 100 megs ?
i've watched a couple series and movies in H265 already
>>53010173
depending on what machine he has since h265 main10 has hw decode support he might be saving on his power bill too, don't forget murricans have ridiculously small data caps so a few hundred megs might be worth saving
is my 2500k too much of a piece of cheese or h.265 lags/loads for fucking 2-3mins when skiping like 5 sec? Or is defcon archive just badly encoded?
>>53010173
>chink cartoons
No. Things like entire seasons of The Blacklist, and Person of Interest. The space savings are substantial, probably in the region of 40 - 50%.
>>53010204
I have an i5 3470, so no, it doesn't have hw decode for x265, but it doesn't matter, because the CPU usage is negligible.
Also, not Amercian, but yes, data caps are a problem.

>caring about filesize
who cares? better quality at same filesize. win-win.
>>53010163

?
Currently, an HEVC-encoded frame looks worse than an AVC-encoded one. However the whole video looks better in HEVC than AVC.

>>53009572
You know very well that they will just increase the bitrate until they are the same size.
>>53010252
>who cares? better quality at same filesize. win-win.
Maybe if you plan on keeping all your tv shows/chink cartoons on your home sever forever, as if its to preserve your memories
>just let it go anons
>>53010290
better quality for same file size is still a plus
>>53010326
The impact on your cpu for decoding x265 is pretty drastic compared to the basically no impact of x264.
>>53010365
Whatever, Nvidia cards already have hardware acceleration for it.

>even if a frame looks worse encoded by x265 than x264 (when comparing frame by frame ), when playing the video is much more pleasant for x265 encoded videos
>>53010280
It makes perfect sense though. Although still frames of a h264 video also look like crap despite looking fine while playing.
I reencoded a chinese cartoon with ffmpeg using a slower preset and a crf of 23 and got these results:
http://screenshotcomparison.com/comparison/162102
It looks considerably worse, but I know shit about encoding. Also, it's 119MB of shit video vs 343MB of cleaner video.
I'll try with a crf of 19 next.
>>53010695
Try 17.5 or 18 if you want almost perfect quality. 16 if source is difficult.
>>53010377
newer intel CPUs and AMD GPUs do too

>>53010377
except for 960/950 they only support HEVC 8bit, which isn't used anywhere.
if the mongolian-rotoscope-encoders will switch to hevc fulltime, they will use 10bit for sure.
16bit when?
>>53011176
well those are the only non-gaming cards worth a damn anyway
>>53011217
How are they not for gaming? They aren't a 980 ti, but their purpose is still gaming.
Something like the GT 710 is a non-gaming card.
>>53010163
Enjoy that quality, tard.
>>53011176
Only a bunch of retards and animufans will use 10bit.
>>53011364
TIL netfilx and amazon are animufans
may god bless the souls of their employees
>>53010774
I'll try 17 then, I accidentally removed the one with 19 CRF. The filesize was about 180MB so a 48% reduction. It also took 102minutes to do that thing. Fuck.
>>53011364
everything out there using hevc is 10bit.
might as well stay with h264 if you want to use 8bit.
>>53011521
I will, h265 is meme a this point.

x265 will be better at some things than x264, x264 will be better than x265 at some things. I've noticed on film (non-animated video files), x265 gives 40-70% better compression. On animated content, x265 actually (usually) performs worse, except on lossless, where it gives about a 10% gain.
It's also slow as hell. 2.5-10fps on medium vs x264's 50-60fps on medium on my computer.
>>53011891
I'm curious, what CPU are you using? I'm getting about 6fps using slower preset and a crf of 19 on a 3570k OC'd to 4.3GHz.

How the fuck do you watch that shit? The dumb woman protagonist not only is the shittiest actress i have ever seen, but her fucking face and voice is annoying as fuck.
She's the weakest link that ruins an otherwise fun show.

Fuck this shit, I'll use CRF 19 for now. mpv was used for playback and xfce's screenshot utility for discovering dark matter.

hwdec=no
Almost the same as the insane presets from an mpv thread.

They won't let me upload multiple screenshots for some reason. If someone has an alternative, then I'll gladly use it.
Filesize:H.264 = 328M
HEVC = 177M
Drastically lower filesize on HEVC. About a 46% decrease from H.264.
HEVC looked softer in some cases, but H.264 looked great at the last two screenshots.
Keep in mind that this is just a reencode of an already encoded chinese cartoon.
Also, I haven't watched the entire video, but Raichi's face was a little distorted on HEVC at the beginning when his face was behind the text.
>>53010204
Techspot just had an article about H.265, apparently even WITH hardware decode it still costs extra battery life and CPU usage compared to H.264. Admittedly negligible amounts, but it certainly doesn't save anything other than filesize.
>>53008612
I'm starting to see h265 encodes in public trackers for tv shows but they're less than 200mb, if they used it to have better quality at like 1-2gb i would download it but i don't want to look at a blob of pixels just to save some bandwidth, i'm not american so i can use all the bandwidth i want
>>53014189
Huh? Most Americans have unlimited bandwidth.
>>53011364
Wrong: 10-bit is the lowest required Main profile in HEVC (Main10) - if hardware only supports 8-bit then it isn't, technically, allowed to say it supports HEVC at all.
At this point, x264 10-bit is still mostly better in practice for anime, especially at the low-end, but x265 is of course still improving and is nowhere near as polished as the x264 encoder - that will definitely improve over time. We are almost at, or according to some, just about past, the tipping point for quality: the speed is uniformly abysmal, however.
NetVC will be somewhat better, but is still in the design/combination phase.
>>53008612
I've seen quite a few shows being released in 265 recently. Unfortunately people seem to think it's a good reason to make files smaller. I don't understand this rationale.
>Use more efficient codec:
> keep quality the same -> make filesize smaller
> keep filesize the same -> make quality better
For some reason everyone chooses option A instead of B. I have no desire to watch a 150MB 720p 40 minute show if some scenes are pixellated. Just make the thing 350MB ffs.
>>53014698
I don't know man. I got about 8TB of animu. If I can reduce 30% of storage, that would mean a whopping 2.4TB of free space.
>>53015942
8TB of animu sounds pretty degenerate, but in any case animu and live action are not encoded the same way. Animu can take up much less space while retaining quality since less information is contained in each frame.
>>53014151
Now for the same ones with CRF 17. My autism is satisfied, I'm leaving now.

Filesize:HEVC = 240.3MB
H264 = 343.6MB
Still a solid 30% decrease, I would be saving about 1.8TB of 6TB of animu assuming a rough 30% decrease in filesize. Converting everything will take forever though. This took 6913.33s, about 4.8s per second of video but I was doing other stuff on the computer. The video is 340.3MB so if we assume the rate is (6913.33s/340.3MB) or about 20.315seg/MB, it would take approximately a whopping 121890000 seconds or 1410.76 days to get everything done on a 3570k with a CRF of 17. Just fuck my shit up.

i7-3820QM. It's one of the fastest mobile CPUs out there, but it's still a mobile CPU. 8.5k on Passmark, so it's actually about 1.1x faster than your CPU.
I average about 7-8fps, the 2.5 is on placebo or with a REALLY complicated lossless file.
>>53013224
Yeah, but VP9 is too slow. ;-; I want to love it, but it just doesn't have the speed I need with all my media files.
>>53010782
Only certain novideo cards, AMD cards dropped the ball on 10bit.
>>53017858
Scene groups will adopt it once the majority can seamlessly decode it.
>>53017858
diaz did it
http://underwater.nyaatorrents.org/?view=ajin-01
>>53017906
Still faster than VP8 per thread for the same quality, so one could encode four WebMs efficiently.
>>53018510
Yeah, but I'm mostly working with 2.5-4 hour 1080p blu ray rips, with 8-channel lossless audio. If I encoded it in VP9 + FLAC, it'd take literally weeks to complete. Until I upgrade, I'm sticking with x264 and FLAC. I really, really want to jump on the HEVC/VP9 bandwagon ASAP, though.
