@inautilo This article has a comparison between animated gif and animated #avif. I wonder how mp4 compares to that?

We ran a simple benchmark where we encoded a set of animated GIFs to both AVIF and JPEG XL. Over the test set, median file size savings percentage was approximately 86% compared to original GIF files and about 73% compared to animated JPEG XL files

I wonder (not) why they compare #AVIF to #JPEGXL but don't mention any advantages of the later, including progressive mode… 🤔

This is really cool, but this is also very much a solved problem with newer codecs like #jpegxl. If Google would just embrace JXL & push for widespread support, we might actually be able to move past JPEG instead of using hacks like this. #AVIF isn't going anywhere outside specific Web use cases, as much as I really like it due to its great coding efficiency for certain quality ranges.

Wonder how much Google paid Mozilla to recommend #WebP over #AVIF here:

AVIF has better compression, and WebP like AVIF can't do progressive display (assuming this page is correct), and AVIF supports HDR (only format).

The only major browser you lose w/ AVIF is Edge, but a little puzzled why Edge doesn't support AVIF if Chrome does, but can i use agrees:

It's not surprising that Google wants to control everything, including image formats. I guess they want to be the cat that gets all the cream. #AVIF #JPEG-XL #Google @FSF

@jurjen_heeck heb #GIMP een maand of wat op mijn #iMac (van 2009 die het nog elke dag doet zonder morren) gezet vooral om #Webp afbeeldingen te kunnen maken - dat is voor PHS nog wel een probleem

nu het #AVIF formaat nog - uh - yep ik kan de formaten wel zien, maar nog niet maken 🤓

Firefox 113.0beta release notes:

AV1 Image Format files containing animations (AVIS) are now supported, improving Firefox’ support for AVIF images across the web.

Yay, now AVIF can be used for both of the two things it’s actually useful for. Still no JPEG XL support.

Just in case a year of silence has not made that obvious, Mozilla has now officially announced their position on the JPEG XL format as ‘neutral’.

The same organisation that once went to great lengths to demonstrate that JPEG was good enough and adding WebP really wasn’t worth it, now (seemingly without a second thought) adds support for yet another video-based codec, AVIF, and all they have to say on the much requested JPEG XL is… ‘meh, not impressed’, basically. No elaboration on what exactly would impress them, or what they found so impressive about AVIF. (Please let me know if you have seen any.)

The GNU project has been criticised for standing by their values but doing little to advance them. Mozilla seems to be doing the opposite: dropping some of them as they advance… to the bottom of the market share chart. I really hope they can climb back on their feet.

Are there any good resources about how to render #videos optimized for the #web?

* What container formats and codecs are widely supported?
* What codecs should be preferred?
* Is #VP9 on #WebP better than #H264 in #MP4?
* Do we still need H264 for compatibility?
* Are there other codecs I should consider shipping? #AVIF? #H265? Do we ever need #GIF anymore?
* What tools can optimize these videos to shrink them as much as possible?
* Best practices for accessible videos? It feels weird that `alt` isn't a thing, but are captions supposed to address that?

I feel like I have a good sense of how to do images effectively after watching enough #HTTP203, but I'm less clear on effective video deployments.

Just noticed that Ikea is one of the first shops to use #AVIF images. That is really nice! Now I just wish I could open AVIF images in the "professional" photo editing software #AffinitPhoto by Serif. Sadly that company is not in the Fediverse so can't ping them and they don't really care about AVIF support as this 2020 feature request shows:…

TIL, do NOT use ffmpeg for encoding avif files.

Same png input, ffmpeg:

and if you use threading (-j all):

Google right now: "Hi guys, sorry for the wait, here's the data about how #AVIF is cool and #jpegxl sucks. We definitely did not use a very old version of Chrome for our tests"

The best thing to do ist upload less video. Use #Av1 for high bandwith high demand streaming.

And mainly use your personal hardware longer and if you can less devices. If you can 7 years. 15 would be great.

The new feature in mastodon to support #heif pictures also can help a lot.

#avif as the open source counterpart would also be great

Analyse: Welches Format löst JPEG ab?

En fait c'est encore un peau a cause d' #Apple qui fait cavalier seul, comme d'hab.

#ios #Avif

Support AVIF pour iOS
Apple préfère utiliser HEIC (High-Efficiency Image File Format) comme format d'image par défaut plutôt qu'AVIF pour iOS. Il n'existe aucun plan imminent pour qu'Apple prenne en charge les images AVIF en local sur ses appareils. L'un des seuls navigateurs mobiles encore incapables d'afficher les images AVIF est Safari. Les images AVIF peuvent être visualisées par les utilisateurs iOS à l'aide de navigateurs web tiers tels que Chrome ou Opera Mobile. Le seul problème est que les utilisateurs ne peuvent pas visualiser les images AVIF téléchargées sur Internet sur leurs appareils Apple iOS, car l'appareil lui-même ne prend pas en charge le décodage AVIF. Dès qu'Apple décidera de prendre en charge le format, on peut s'attendre à un changement massif pour donner un support à tout l'écosystème d'Apple. Le support de leur navigateur Safari dépend du support du système d'exploitation, comme nous l'avons expliqué dans notre article sur Safari.

Heureusement il y a des gens cools qui font des plugins ^^

with jxl, we have a format that not only does lossy compression with the best of them. unlike the video-codec derived and also free and upcoming #AVIF, it does not blurs and smudge the image at low qualities, which means blockyness but also some better preserved texture.

but it really shines in lossless compression. it eats even highly optimized PNG for breakfast, and it also does simple animation, replacing APNG, and yes GIF.
