Description

Sources and Links

Quick Info

Stuff

There it is, finally, the entirety of Kodomo no Jikan, at least what comes from the source DVDs. Basically everything is included, the 1st season, 2gakki/Nigakki, OADs and everything extra that comes with the DVDs such as the openings and endings without the credits, the TV Commercials, the DVD Advertisements, the VAs messing around and showing various KoJikan goods and merch, even a live performance of some songs, all included and a few more. There is also the Audio CDs which I got long ago out in the wild, but I coudn't find it again searching for it now, so I can't give a direct link to their source because it's possibly lost. I took this chance to rearrange the files my way, and also to fix an error where the TV Opening and Ending contents were misplaced on the opposite folder. Everything from the source is still there, I just rearranged everything and saved the original things into an Extra folder.
For the Audio CD rips, all credits goes to AniBoters, and for all the subtitles, the credits goes to Doutei.

Note that, although the resolution of the video is 720x480, which is a weird square 3:2'ish aspect ratio, the display aspect ratio is 16:9, from the source. So the video resolution is 720x480, but thanks to the 16:9 aspect ratio, it is stretched to something like 853x480. Again, the source is already like this, and no upscaling or something was done. This is handled by the display-width and display-height tags that matroska has, so it is completely lossless and non destructive.

This anime was quite annoying to deal with, I already tried encoding it in the past and had problems, but even knowing what to expect it was still annoying. I almost gave up at some point but managed to power through. Every tool I tried analyzing it with gave me different results, if I tried this, that would get messed up, if i tried that, this would get messed up, it was sad. But after days and nights of testing, trying and retrying I think I got to a nice result. As usual I didn't applied unnecessary post processing, instead trying to stay closer to the original material, just doing necessary things.
A lot of this release was experimental, kind of trial and error, so it took longer than it should had. Also this time I didn't used NEAV1E, instead I went with av1an, and big thanks to the people on av1an Discord server for helping me and dealing with my excessive writing. I wanted to try av1an for a while already and after I've got better results with it, I decided this is what I will be using from now own. All the operations on the video files were made while in ffv1 format, so totally lossless.

Update on 17/NOV/2021: I have some releases planned, and I got the material, but things will take a bit to happen again. While doing test encodes for a certain source using grain synth, I almost popped my motherboard's VRMs. And I've got a harddrive failure, so I won't be seeding as actively as before, but will still do from time to time to not stress it, since I'm still using this possibly defective disk.

Thanks!

Thanks for this. I have the original KBS Kyoto broadcast version of season 1 from back in 2007, subbed by the awesome but now defunct Underwater. I'm interested in comparing the video quality from the TV broadcast to your DVD source. Thanks again. This is an underrated and sadly misunderstood series.

10/10 perfect release!
Can't wait for your next project
AV1 is the future!

@ stealthmomo ... yeah this was a badly misunderstood story ... I was very glad that SaHa was scanlating it, because he did good quality work

I seem to remember that there was an "uncensored" version of the series that came out in a bigger screen size than 480p ... I want to say is was uploaded by someone called lolipop subs ? but it has been many years since I had gotten that version

LOL ... found it, though yeah it is LONG dead ... it was from 2008 ... https://nyaa.si/view/27590

The series is a favorite of mine, with lots of lighthearted moments, as well as touching on some fairly big issues rather well. It really surprised me just how real the characters are, like the teachers are human beings with their own problems, but they're still trying to care for these kids as best they can. Not to say it isn't heavy on the fanservice, but man, I wasn't expecting how much more it had to offer.

Nice.
It would be good to include that in a file giving credits at least for the subtitler.
I don't see a need for av1an any longer. The AOM encoder handles encoding multithreaded well. Splitting the video up and then rejoining it, as av1an does, is a kludge.
We can play 10bit 480p encodes on a PC without dropping frames, but if you encode higher resolution video, beware that it could drop frames on a PC even though it plays without trouble on a TV. That is because there is acceleration for 10bit video decoding for ARM processors, but not PC processors. PCs need 8bit encoding AV1 for higher resolutions. For higher resolutions, i would consider down-scaling the luma resolution to make it match the chroma -- YUV444. If it is an issue, video players can apply their own de-banding.

@Hogoledo I added Doutei's name on the subtitle track name, which will show all the times someone wants to change the subtitles or look at the files properties with mediainfo and stuff. But next time I will start to add a file on the master directory crediting the sources I got things from.
About aomenc, I have a build from the last week of the past month, and it was still using like 10% of the cpu on it's own... By the way, av1an does not split the video, like, reencode chunks of it to intermediary files to encode them to av1 and assemble them again, neav1e does that. av1an pipes to the encoder from the input file itself, using scene detection and keyframes to tell the workers where to start and stop, kinda. When I said about intermediary files, that is because I don't know how to do everything solely via vapoursynth scripts yet, so I need to do things in 2 or 3 steps, but it should be perfectly possible to do all in one vapoursynth script and go straight from the original file to the final one as av1an accepts vapoursynth script input, without any kind of intermediary file, principally considering I don't apply post processing and stuff.
About the video playback, even my phone which is like 4 years old at this point and has an SD845 can play 10 bit 1080p60 av1. I like to do stuff just for the sake of it, I have various 4k60 videos I upscaled and interpolated myself which I eventually encoded to av1 while doing various tests and they play perfectly fine as well, and I only have a R5 3600. av1 isn't as crazy hard to play as people might think, at least on mildly decent hardware.
Note that RTX 3000 and RX 6000 GPUs have hardware av1 decoding already as well so even if one's CPU might be underpowered, which shoudn't be very common in this day and age, if one has one of the current gen GPUs, they'll be set for a while.

Edit to clarify a few things, sorry for the wall of text ><

@hogoledo, that is not true anymore.

VLC currently uses dav1d 0.9.0, which has all the AVX2 SIMD required for very fast 8b-10b playback. That means all CPUs from Haswell i5s and onwards and Ryzen 1+ CPUs won't have trouble playing AV1 content any longer.

Recent versions of mpv use dav1d 0.9.2, which has SIMD acceleration for SSSE3 and AVX2 code, basically supporting all current modern x86_64 CPUs, meaning even a Core 2 Duo won't have much trouble on a 1080p30 10b video with grain synth on.

In fact, per thread, dav1d can software decode faster than ffhevc, which is an impressive feat :)

Anyway, the 10-bit stuff isn't really much of an issue anymore.
