Encoding Details:
This is the first release to be encoded with a Normal CRF Distribution Multi-Pass encoding setup. We will refer to this as the “Normal-Boost” from here on out. As such, the CPU preset and CRF values were selected per scene based on an initial measurement of quality from the first pass and thus the two values listed in the command below are inaccurate. For the most demanding scenes, a minimum of preset 4 and CRF 12 was used. Conversely, the simplest scenes would have a preset of 6 and CRF 28. However, most normal scenes are weighted towards CRF 16. This allows for smaller file sizes and improved quality in select scenes. A similar technique was applied manually by hand to our Selector Infected WIXOSS release. For more details, experimental data, and other wild conjectures, we invite you to join us in the Discord server.

This project is a production with the goal of the smallest video size with moderate subjective compromises to image quality. This is not the hallmark of AV1, but close enough. This release should only contain changes to the video stream and audio tracks. The subtitle and attachment tracks are usually copied from the noted sources. Timings are not adjusted except in cases of extreme delay as a result of mixing sources. -

Statistical Image Comparison Analysis:
We measured the SSIMULACRA2 score for 1 of every 5 frames in this release and plotted them into a histogram for some rudimentary statistical analysis. Those can be accessed here. We also included the raw data in the Quality Audit.json
file along with a few other simple computations such as average and standard deviation. Below are 3 random graphs from this collection:

Brilliant thank you, I’m assuming you’re doing the rest? If so do you a have timeline set?

Love this nerd shit. So happy there are encoders out there actually using intense experimentation and data to improve their releases and not subjectively playing by ear (literally) like a certain “lossy-mode wavpack is totally better than opus because my totally real golden ears say so” guy…
192k opus audio is overkill for simple stereo TV anime but I get it. These aren’t minified encodes, might as well tack on some extra audio bits so even the most pathetically deluded weeb can’t complain about perceived artifacting.
I like FLAC for music archiving of CD’s or studio masters, but for the anime encoding community I honestly hope the days of FLAC will soon be over for anything except BD raw rips.

@nph Holy shit. Shut your whining bitch ass up and encode the audio down to the lower quality you desire you super hearing lazy fuck. That is never going to happen.

@warui
you’re weird. I wasn’t complaining at all, seems like you were having a bad day and took it out on someone online after deliberately taking the most uncharitable interpretation possible of their comment. Hope your life stops sucking so much shit soon and you learn how to interpret comments in multiple ways before giving in to your weird, misanthropic urge to only see something in a negative light.
FLAC only makes sense for raw/remux rips where no video compression (or minimal/lossless compression) is used. If you are releasing a torrent that is NOT a BD Raw, ripping the audio as FLAC is completely ridiculous - more and more people are slowly realizing this which is why I’m not particularly worried about dipshits like you.
Putting the onus on the downloader/viewer to re-encode the tracks to their preferred codec is stupid as it prevents them from being able to seed without cloning the torrent to another download location, which is a further waste. Not wanting to spend an hour re-encoding audio to a sensible codec that should have been used in the first place isn’t lazy.
Wanting to move on from the days where a single audio track is 20-25% of the bitrate of a compressed MKV release is also not lazy. It’s sensible.
A lot of misinformation about codecs and subjective quality issues gets spread around Nyaa and other torrent sites. There are tons of dweebs on here who are convinced they have golden ears (nobody does, it’s a myth that has been debunked repeatedly).
