Netflix starts streaming over the AV1 codec to reduce data consumption
We've mentioned the AV1 codec a couple of times already. AV1 is a royalty-free codec and offers improved compression compared to vp9 or hevc, the video bandwidth reduction can run upwards to 30 percent, without you seeing a difference. The best thing yet, this is a royalty-free model.
It is stated that AV1 can approximately be 30% more efficient than h.265, which the streaming service currently uses for the users of its 4K subscription. Compared to vp9, it would be 20% more efficient.
-- Netflix --
Today we are excited to announce that Netflix has started streaming AV1 to our Android mobile app. AV1 is a high performance, royalty-free video codec that provides 20% improved compression efficiency over our VP9† encodes. AV1 is made possible by the wide-ranging industry commitment of expertise and intellectual property within the Alliance for Open Media (AOMedia), of which Netflix is a founding member.
Our support for AV1 represents Netflix’s continued investment in delivering the most efficient and highest quality video streams. For our mobile environment, AV1 follows on our work with VP9, which we released as part of our mobile encodes in 2016 and further optimized with shot-based encodes in 2018.
While our goal is to roll out AV1 on all of our platforms, we see a good fit for AV1’s compression efficiency in the mobile space where cellular networks can be unreliable, and our members have limited data plans. Selected titles are now available to stream in AV1 for customers who wish to reduce their cellular data usage by enabling the “Save Data” feature.
Our AV1 support on Android leverages the open-source dav1d decoder built by the VideoLAN, VLC, and FFmpeg communities and sponsored by the Alliance for Open Media. Here we have optimized dav1d so that it can play Netflix content, which is 10-bit color. In the spirit of making AV1 widely available, we are sponsoring an open-source effort to optimize 10-bit performance further and make these gains available to all.
As codec performance improves over time, we plan to expand our AV1 usage to more use cases and are now also working with device and chipset partners to extend this into hardware.

So now all the salesmen and marketeers of all sorts of consumer hardware (TVs, AVRs, set-top boxes) are rubbing their hands with glee, as all our current hardware only has accelerated H265 codec support, and to have hardware supported AV1, you now need to buy new machines again from them.

Well the vast majority of all movies visual effects are mastered at 2K (and still are even for modern blockbusters with mega budgets) ... and even the finished movie masters are still 2K.... because of time & storage costs associated with 4K rendering.
This is why nearly ALL 4K discs are just 2K upscales. They may have HDR and WCG and higher bitrate... but still only 2K upscales from the only available master done. Makes a mockery of the whole thing I think.
all the visual effects would have to be remastered because they were done in 4k in the first place,

for starters 4K doesn't really exist except on youtube, bought a 77" 4K LG oled when I wanted to show it to friends I used youtube channels to do it not movies nor series
most recent movies are 2K because of rendering times (worst case scenario 1 frame from a 24fps movie can take 30hrs to render ! needless to say they need hundreds or thousands of computer for months to render high amount of VFX movies)
tv series are made for broadcast so they couldn't care less and/or also suffer from the rendering time problem (remember that night battle in GOT where you could see early divx era compression blocks ?)
grain is detail, blur is lost detail...and so my sharpness is set almost at max
the only detailed "good" looking are older movies remastered in 4K, because digital age movies look like a blurry mess
if you want to see/show real good quality 4K
Jacob + Katie Schwarz youtube.com/channel/UCYq-iAOSZBvoUxvfzwKIZWA
Nature Relaxation Films youtube.com/channel/UC4lp9Emg1ci8eo2eDkB-Tag (this one isn't as good as there's lot of drone footage but lots more content uploaded)
this is what they should show to sell tvs because people can't believe their eyes when they watch this (with high sharpness settings :p not I'm drunk/half blind settings)
Since we entered the age of HD you actually need to sit closer to TVs for your eyes to be able to see the details ,something a lot of people especially older don't get so here's a link for your friends or family https://www.rtings.com/tv/reviews/by-size/size-to-distance-relationship
to "see" 4K on a 55" you need to sit at 1m or less from the screen heh
Actually the distance to sit from a 4k tv depends on its screen size.
A 40’’ TV– You should sit between 3.5 and 5 feet away from the screen.
A 43’’ TV– You should sit between 3.5 and 5.5 feet away from the screen.
A 50’’ TV– You should sit between 4 and 6.5 feet away from the screen.
A 55’’ TV– You should sit between 4.5 and 7 feet away from the screen.
A 60’’ TV– You should sit between 5 and 7.5 feet away from the screen.
A 65’’ TV– You should sit between 5.5 and 8 feet away from the screen.
A 70’’ TV– You should sit between 6 and 9 feet away from the screen.
A 75’’ TV– You should sit between 6.5 and 9.5 feet away from the screen.
An 80’’ TV– You should sit between 6.5 and 10 feet away from the screen.
An 85’’ TV– You should sit between 7 and 10.5 feet away from the scree

4k oled is still great for great documentaries on netflix and newer series in dolby vision.
While full hd bluray still play super nice with or without upscaling.
high bit rate 1080p on the bluray is still nicer to my eyes than anything 4k you can find on youtube.
