Netflix To Re-Encode Entire 1 Petabyte Video Catalogue In 2016 To Save Bandwidth (variety.com)
An anonymous reader writes: Netflix has spent four years developing a new and more efficient video-encoding process that can shave off 20% in terms of space and bandwidth without reducing the quality of streamed video. With streaming video accounting for 70% of broadband use, the saving is much-needed, although the advent of 4K streaming, higher frame rates and HDR are likely to account for it all soon after. Netflix video algorithms manager Anne Aaron explained to Variety that certain types of video benefit little from the one-size-fits-all compression approach that Netflix has been using until now: "You shouldn't allocate the same amount of bits for My Little Pony as for The Avengers."
"You shouldn't allocate the same amount of bits for My Little Pony as for The Avengers."
So they're dropping the resolution for The Avengers?

Shaving 20% off seems pretty optimistic to me. Unless they've suddenly discovered some whole new realm of compression mathematics I'd be surprised if thats anything more than a peak compression in some rare edge cases.
Sounds more like as a part of re-compression, they are going to drop the bitrate (and video quality?) for videos that don't "need" it:

What problem is this trying to address?
Saving on bandwidth costs?
Providing a better streaming experience for customers on poor or throttled connections?
Storage space savings?
Getting the satisfaction of doing something better because why not?
As a My Little Pony enthusiast who pays the same per month as everyone else I demand the same quality as the Avengers.
The article is actually in English, you know.
"The new system will encode from the raw source material more intelligently, considering whether or not the material itself can really benefit from higher bit-rates, or whether identical quality can be maintained with less space and bandwidth."
