What is H.265 (HEVC) video compression? How is it different than H.264?
It's better
I wish it was more popular, only niche players are encoding in it right now.
Uses more processing power to decode video that's compressed further.
In short you're using more processing power to get more quality out of smaller filesizes.
ELI5? Google it like you're an adult.
Only marginally so. The downside is it takes so long to encode compared to x264. The quality/performance ratio isn't there yet.

i heard it's highly efficient

>decoding on the fly
it's dead on arrival as it's basically unusable in notebooks and phones
>>53856436
I never had any problems at all with it on my laptop.
Most HEVC patents are owned by Samsung and BBC.
It's the primary reason Apple products have been very slow to adopt it.
It's 0.001 better!

It's a shitty new codec that is 30% smaller than H264 with the tradeoff that it can't rrender your chiense cartoons faster than 4 FPS and it sets your laptop or mobile on fire when you try to run it on those.

Zero problems on my Z3 Compact.

Try getting a better computer, bro.

It's great, with my shitty 1MB/s internet, I can now download 720p as fast as standard resolution. That's cool.

>just think of all those megs you're saving!!
whose fucking idea was this
>>53860212
It's a new codec lacking widespread hardware support, of course it's going to be bad on CPU and battery at the moment.

You mean CPU power ceiling has been advancing slowly.
CPU power efficiency has been advancing by leaps and bounds in the meantime.
And battery advances would be larger if companies didn't insist on making everything paper thin.
>>53860266
the issue is that your argument sucks
if a 1280x544 video uses 36.2% CPU what is 1920x1080 with 66% more pixels going to use?
YIFY 265 when?
>>53857083
I can play 1080p x265 videos just fine on a 5 year old intel atom. If you have problems than your poor ass should get a new computer.
>>53860336
My argument doesn't suck because 2560 is pixel double of 1280 so it scales perfectly.
>>53860212
Yeah have fun making 4k BDs with x264
>>53860361
and 1920 is 3/4th of 2560 meaning less pixels will have to come out of your ass
also

>CPU power efficiency has been advancing by leaps and bounds in the meantime.
kek. general purpose power efficiency has been improving at a crawl, only special functions given new dedicated hardware (video codecs, AES, etc.) have substantial apparent power efficiency gains.
>>53860430
And what point was that? I never said anything about processing power. All I said was it's perfectly fine to play such a resolution on a 2560x1440 monitor. Any additional points you tack on are irrelevant.
>>53860444
My point was about >>53859607
I assumed you were the same person
Nice trips by the way
Yeah it's shit
>Encoding time x10 h.264
>Most VGA's still not support native decoding
>too much grain, not good for grainy sources(everything)
>Rain,snow,dark scenes look like shit cause Grain
>Muh Chinese Cartoons
And also Vp9>x265 due to enconding speed x5, with only 5% more file size
Maxwell GM206 GPUs support HEVC & VP9 hardware decoding, all decoding steps fully done in hardware decoder for lowest CPU usage even on 4K high bitrate videos
Pascal family will support HEVC & VP9 hardware decoding top to bottom
>>53856150
The thing that pisses me off with the adoption of h.265 is that instead of using it to make higher quality videos, most release groups seem content to simply reduce the file size of their 1080p and 720p rips.
>>53860212
You're forgetting that Pixel counts are also increasing.
>>53856150
daiz has fully switched to h.265 HEVC for his encodings
>>53856150
I downloaded a TV show in 1080p/5.1 h.265 last week. I could hear my laptop fans ramp up whenever I played the videos. Shit looked crisp and the filesize was pretty good too. It was virtually unplayable on my G4 though, lots of lag and the audio was out of sync. I ended up deleting the files.
I wish there was more support for it.
