It is irrelevant how performant proprietary video codecs are.
There is zero purpose dedicating any time or energy supporting a system where every client and server has to pay a license to use it.
AV1, and upcoming open-source royalty-free competitors are the only future for video encoding.
Once I finished the first codec comparison, I discovered that both of the AV1 codecs I was testing had received substantial updates in the interim. I made the following post looking at how they have improved. https://colinmckellar.com/2024/02/21/av1-codec-update/ #AV1#ffmpeg
Hey everyone - wanted to announce a nice Aviator update that happens to coincide with an SVT-AV1-PSY update that we pushed just yesterday.
Aviator 0.5.1 has a couple new features, but chief among them is a new Subjective Tuning toggle for enabling encoder changes that improve visual quality at the expense of metrics. This is powered by SVT-AV1-PSY's new Tune 3 authored by Clybius; it adds subjectively motivated optimization to the existing Tune 2's great performance for an incredible balance of retaining fine detail in videos while still preventing blocking.
Here's a comparison encoded with Aviator (both 10-second videos were 7.5MB, down from the lossless source's 732.8 MB): https://slow.pics/c/tdrO5dY4
(the source is Netflix's foodmarket at 1080p)
If you prefer the smoother-looking, more appeal-oriented shot here, that is OK too - Subjective Tuning is toggleable!
Aviator 0.5.1 should be available on Flathub pretty soon. Enjoy!
Edge 121 arrive également avec le support du codec vidéo #AV1
Toutes les versions de Edge 121 auront un support d'AV1, via le matériel ou via logiciel (s'il n'y a pas de support matériel).

AV1 fonctionne parfaitement sur mon vieux PC Core2 Duo de 2007 par exemple.
C'est fait: Microsoft #Edge 121 est sorti avec le support #AVIF et #AV1 pour tous 👏
Cela permet de diviser la taille par deux par rapport aux formats legacy (H.264, Jpeg, PNG, GIF).
Tous les navigateurs ont maintenant le support de AVIF.
SVT-AV1-PSY is the Scalable Video Technology for AV1 (SVT-AV1 Encoder and Decoder) with perceptual enhancements for psychovisually optimal AV1 encoding. The goal is to create the best encoding implementation for perceptual quality with AV1.
We've already implemented a couple of unique features not present in mainline that do appear to produce BD-rate gains on a number of clips already!! Please check it out!
I recently got it into my head to compare the various popular video codecs in an effort to better understand how av1 works and looks compared to x264 and x265. I also had ideas of using a intel video card to compress a home video security setup, and what levels of compression I would need to get good results....

Hi everyone! I wanted to introduce Av1an Command Generator, a relatively simple tool I wrote in Zig for generating Av1an commands for #AV1#encoding based on a limited set of parameters. GitHub link is below:
The bar to entry for understanding effective Av1an scripting is very high simply because there are a lot of well-documented ways to incorrectly set your parameters and very few who know what is psychovisually optimal. I am not one of those few, but because I know members of the AV1 community who've poured great time and effort into researching this kind of stuff, I am able to build from what they've learned. My more advanced tool, rAV1ator CLI, is also based on this research. I hope you enjoy!
Nachfrage bei denen, die sich mit Videokompression im Allgemeinen und AV1 im Speziellen auskennen:
Generell: Wenn Filme von Blu-Ray und DVD sowie aus Mediatheken platzsparend gespeichert werden sollen, kann dafür heutzutage guten Gewissens schon AV1 eingesetzt werden? Als OpenSource-Freund würde ich ungern H.264 oder H.265 einsetzen wollen.
Dann: Wie kann ein AV1-codierter Film auf einem einfachen TV-Gerät angezeigt werden:
Gibt es dafür per HDMI anschließbare Boxen mit Hardware-Decodierung?
Kann ein Server im Netz das Decodieren übernehmen und ein FullHD-Bild bereitstellen? Wenn ja: Was für Software wird dafür eingesetzt, Kodi oder etwas anderes?
After years of using #ffmpeg I only discovered today that you can also use the option :"-cpu-used", default 1, damn if I knew before, now I can also quickly convert an #AV1#AOMedia#linux#OpenSource
Un autre problème d'#Edge est que le codec vidéo #AV1 ne soit disponible qu'en option, et uniquement sous Windows (Edge est disponible sur Android, Linux, Mac, sans possibilité de lire AV1).
Bonus: Le code de l'extension AV1 de Windows 10 ne fonctionne pas sur de vieux PC.
Today I released rav1ator-cli, a little terminal script that lets you easily interface with Av1an among other things! Read more about it & learn how to install here: https://wiki.x266.mov/docs/utilities/rav1ator-cli
The #unity situation reminds me of the events that lead to the development of #av1. Few people cared about open formats until a money grabbing change made people realise "ya know, this company we depend on could totally bankrupt us". Despite a change in policy saying they were kidding about the price hikes, too many people were scared to put the genie back in the bottle. Not exactly equivalent since #godot exists.
