There are nearly 100 experiments that are in the code base(some presumably don't work with each other). If the signalling for a large combination of those is practically free it would make sense to integrate as many as possible if they can be of use to an encoder later down the line, as long as the decoder doesn't become too complex.

What does confuse me is how Netflix and Google seem to be coming up with rather different percentages of improvement(20% vs nearly 35%?). Probably a combination of differing builds and metrics.

As H.266 is already in development http://mpeg.chiariglione.org/standar...e-video-coding
it's very likely that development of a new format will be launched after AV1.

Hello everybody,

I'm a media student of a university of applied sciences in germany and I have a lot of questions concerning the work of the new AV1-Codec of AOM. I know it is terrible when newbies are coming to a forum with a lot of real experts in it. So I won't ask my stupid questions here, but I'd like to know where I could ask them without spamming too much.

Have a nice day all togehter. :)

well this forum i guess.

but not sure if a real indeep AV1 codec profi is present/active on this forum.

so i recommend you to open a new thread in a matching sub forum or maybe even here and just post your question. so a person able to answer your question is present and willing to answer you may get your answer. if "not" you may not get it.

and like always first.

staxrip's AV1 support is now completed, better early than late.

Except it can't be complete as long as the codec isn't even finished. Should not encourage people to make files that eventually nothing will be able to play.

Yeah should be marked as "experimental not frozen" in the GUI on the other side Staxrip is not really a avg joe target GUI Methodology so rather unlikely that the target group of it isn't aware that AV1 isn't absolutely ready for Production.

@nev

Are you worried about future bug reports?

There is a warning I leave until it's finished.

Code:
MsgWarn("Please note that AV1 is unfinished!")

please add in bold "and shouldn't be used for any serious Production purposes yet, risk be none of your files created now with it will ever work in the future and only cause headaches, this is highly experimental"

@CruNcher

I changed it to this:

Please note that AV1 is unfinished/experimental!
The bitstream format is not yet frozen.


Should be clear enough.

not sure if the AVG user understands this as "it is very unlikely that my file will work in the future".

you can not assume that an AVG user knows what a bitstream format is.

For this people warning in not necessary, the current encoding speed is enough .

AV2 or AV3 will be out until they finish encoding there first movie.

It take me 5 min to encode foreman clip (300 frames 352*288).

OK, now it's this:

Code:
            MsgWarn(
"Please note that AV1 is experimental!",
"The bitstream format is not yet frozen. It's very
likely that files created with the current encoder
become unreadable in the future.")

From Timothy B. Terriberry's VDD17 presentation :

see : https://bambuser.com/v/6908002#t=2416s

Planning soft bitstream freeze by Oct. 31st


● Definition of “soft” is soft
– Some think it means “only critical bugfixes”
– Some think it means “we can tweak anything”
– Reality likely a pragmatic mix
● IPR analysis is not complete

From Netflix VDD17 prsentation :

Teaser : codec comparaison :

Very interesting... but please use the latest build (v2.5) of x265 in your comparisons. v1.9 was released in January. Also be sure to use --tune PSNR for your PSNR comparisons, and --tune SSIM for your SSIM comparisons. Ideally, use VMAF for your objective comparison.

Can't wait for the new Netflix codec comparison.

@x265_Project, yes agreed with you, x265 version is pretty old in this comparaison.

from Netflix teaser ( https://bambuser.com/v/6909221#t=2465s ) I don't see the versions but it use vmaf that should be better.

Full Netflix codec comparison should give more details.

HS : x265_Project, is this someone from your team ? https://bambuser.com/v/6909221#t=205
