>encoding still takes thousands more resources than x265 Nobody cares
Julian Gomez
That's down to 14x already
Carson Moore
lmao no it isn't, a month it still took ~3,000X more resources to compete with x265 efficiency using the medium preset. No way it'd down to 14x
Lucas Cox
And? OP talks about a decoder. Also aomenc's fastest preset + tile based multithreading is comparable to x265's slowest preset for encoding 1080p footage, last time I tested it about two weeks ago. It's not as bad as it used to be, when that one article compared AV1, HEVC, AVC and VP9, where AV1 took like 200k seconds for a short clip. Not saying it's usable yet, but it's slowly getting there.
Landon Hill
YouTube engineers already said so
Benjamin Campbell
>slowly More like infinitely slowly. Anyway decoding means jack shit if qualcomm or intel/amd don't have HW decoders that consume less than 1 watt
Austin Hill
For hardware encoding maybe but it won't match 265x's compression efficiency and performance on the medium preset even in a decade.
Christopher Morales
>More like infinitely slowly. How so? Compared to other codecs AV1 is barely a child.
That referred to VP9 and unless you're using Google's approach of splitting the file and encoding those parts simultaneously, VP9 encoding via libvpx is a lot slower than HEVC encoding via x265.
Dylan Cruz
Reminder that AV1 will kill film grain from analog sources with it's DNR + realtime "grain-re-addition".
Tyler Cruz
>faster than aomdec :DD Okay, but is it competitive with VP9 and HEVC?
Juan Gutierrez
brainlet here how to test dav1d the easiest way???
Dylan Torres
It took 2 days to encode a movie with x265 for me How long will it take with (((DAV1D)))?
Matthew Perry
Maybe a decade at best.
Tyler Lee
and this is bad?
Adrian Adams
ffmpeg and Jow Forums webm support when? HIRO USE VP9 ALREADY REEEEEEEE
Dominic Davis
>how long will it take to encode with a decoder dunno
Ethan Harris
Upgrade your toaster
Sebastian Anderson
Yes, it will reduce original detail and make the re-drawn grain inauthentic to the original. It's fine for digital sources wishing to add digital grain filters, but it's ripe for misuse on analog sources.
Isaac Reed
Why are decoders and encoders separate? Why isn't it like XORing where decoded -> encoded and encoded -> decoded?
Luke Mitchell
Who cares, everyone is already moving on to .wmv and .rm in .avi
Easton Richardson
>but it's ripe for misuse on analog sources. True, but then I'd blame the person who makes this decision, not the codec for offering the option. It's fine for videos where the bitrate is too low to preserve the grain in the first place.
Didn't they just announce breaking changes to the format of this already obsolete crap you're trying to shill?
Wyatt Anderson
Probably not much. x264 is still great for encoding anime and with the current encoding speed of aomenc and rav1e you'll get some test encodes perhaps (just recently someone uploaded an AV1 encode of some show with bunny in the title), but that'll be about it for the next few years.
Apparently they want to make some changes to make hw implementations easier. Not much is known about those changes though.
Grayson Campbell
Won't even make the slightest different now that 10-bit x265 is cream of the crop for chink toons.
Gavin Allen
no
Juan Hill
Yes you troglodyte, we've had 10-bit HW decoding for like 5 years now.
Levi Cooper
>Windows 7 : Dav1d is slower on Firefox, it uses about 50% more CPU with 720p video
AHAHHAHAHHAHAHAHHAHAHA
Benjamin Bailey
>dav1d in Firefox Nightly doesn't enable assembly builds just yet so performance is comparable to the C version >Firefox nightly is still slow, because of build issue and their sandbox. It will get faster... bugzilla.mozilla.org/show_bug.cgi?id=1511224
Jason Smith
>w7 oh no
Connor Cox
2030 maybe
Ethan Gutierrez
But dav1d hasn't even be ported to FF yet.
>We're finishing the rough edges for a release soon, so that we can hope thatFirefox 65will ship with dav1d for AV1 decoding.
Jackson Gonzalez
You'll see AV1 rips from streaming sites in a few years. Fansubs will probably continue using 10bit x264. Low quality AV1 reencodes will show up similarly to how x265 is used now.
Gavin Adams
>Low quality AV1 reencodes will show up similarly to how x265 is used now.
Realtime applications for hevc and vp9 are already fgpa dependent.
Evan Anderson
Fine with me, x265 being much more forgiving of the scene's retardation is a god send. >inb4 muh private trackers If the average encode on ptp is any indication 8bit x264 encodes are all starved.
Owen Taylor
>No mention of av1
Lincoln Thomas
>10-bit Great! >x265 Eh. Depends on the bitrate.
Jaxon Carter
>he thinks
Grayson Long
>even in a decade. You must be really new on topic to not remember the same shit about x265 when it encoded at less than 1 fps.
Jaxon Carter
>>he thinks
Asher Hill
no one does even tried using a 1.5gb 45min video with x265, vs a 3gb x264 video, the x265 looked like hot garbage
there was no detail in anything anywhere fucking YIFY quality.
Ryder Smith
I'll wait for 1.0
Dominic Gutierrez
mad cuz you're busy fapping all day and they optimized an encoder that much?
They designed the licensing system to revoke if you are involved in any patent litigation.
What will happen is that they will let it slide until wide adoption happens and then use it to extort money and charge huge licensing fees.
What a fucking joke.
Christopher Carter
This is what happens when browsing Jow Forums has completely ruined your brain
Daniel Foster
It's a reverse patent troll designed to destroy competition.
Landon Baker
nice try, shill
Carter Myers
I was excited for this at first but now I realize I don't care.
This type of thing only matters for archivers, people with download caps, and limited space. These people aren't going to use new encoders to create better quality video. They're going to keep the same quality now and simply use it to reduce file size, that's it.
Combined with the fact that x264 will stick around for the foreseeable future due to much faster encoding, especially for livestreaming. It's difficult to care.
AV1/h265 = for people trying to fit video on a 700MB CD
VP8/VP9 = making clips with webms
x264 = king of everything else
Adam Miller
except all the clips available on youtube av1 test playlist look much better when av1 turned on
Jayden King
>This type of thing only matters for archivers, people with download caps, and limited space. this is retarded thinking
Carson Rivera
Show bitrates.
Easton Lopez
That's because they are encoded at a high bitrate. See the playlist's description >At time of writing, these transcodes are encoded at a very high bitrate for decoder performance testing. If you encounter an AV1 outside of this playlist they usually have a smaller bitrate compared to the VP9 stream at the same resolution. Ultimately Google will try to achieve the same visual quality with a lower bitrate.
