Aika Zero (BD 1080p X264 10bit - FLAC 2 0) [Quetzal] [v2]
This release has a brand new 1080p encode by myself, with the same subs as audio as earlier releases. Filter chain is antialiasing -> dehalo the second chroma plane -> luma dehalo on certain scenes -> denoise -> deband -> adaptive grain.
Comparison with Winter (upscaled to 1080p in MPV with FSRCNNX) and Yousei-Raws: https://slow.pics/c/xBsICY8i | http://compare.bakashots.me/compare.php?setId=4495 | **Careful, screenshots are sometimes NSFW!**
My original remuxes used Yousei-Raws' video for 1080p and Winter's for 720p, but I wasn't really satisfied with either of them. Yousei-Raws' video is reasonably transparent, but lacks any filtering to fix the various artifacts present in the BD. Winter's at least fixes the banding, but also has substantial detail loss and compression artifacts, is only 720p, and doesn't fix any other issues.
Filtering this show was more difficult than I expected going in. To start, getnative results were too ambiguous to determine the native resolution, so I couldn't rescale. Instead, I used a more conventional aa filter with a generously expanded mask to keep artifacting to a minimum while still reducing aliasing pretty effectively. Scenes with credits and similar elements weren't filtered with aa.
Strangely, there's a ridiculous amount of haloing on only the second chroma plane. Fixing this without causing excessive detail loss was a challenge. In the end I settled on a four-step filter chain (really two steps applied twice each), which heavily reduces the amount of haloing while unfortunately sacrificing a little chroma detail. To my eyes this was the best result possible, with other filtering choices either causing too much loss or missing a substantial amount of halos.
The images shown during the first and second ending song suffer from heavy luma haloing. The first episode got a stronger filter than the second because the background in the second episode's ED is much more delicate. Credits and the Aika Zero logo which play during the opening song were also filtered with the weaker luma dehaloing.
Debanding was another challenge, at least for episode 1. While episode 2 and 3 have dynamic grain on the BD, episode 1 has no grain whatsoever which means lots of banding and blocking. Unfortunately with debanding filters, there's always going to be a tradeoff between debanding strength and detail preservation. I can't say I'm completely satisfied with my results, but I did manage to deband nearly as effectively as Winter while retaining detail much better. Most of the video (including episodes 2 and 3) is comparatively more weakly debanded, with a handful of scenes getting a stronger filter applied.
In the end, I don't think the results are perfect, but I do think they're better than anything else available. o/
Audio is 16-bit FLAC from Yousei-Raws because no retiming was necessary. Subs are the same as in my Winter remux, which means FTV's translation with Seto-Otaku's typesetting (I slightly adjusted kararoke effects and sign timings), and some blank lines which were timed to after the video ends removed (these were causing MPV to incorrectly report episode length).
Feel free to message me if you notice any problems with this release or just want to give feedback. n_n (My QC is kinda lazy)
