file for each album and was added replay gain data for all the tracks.I’ve had this done for a long time already, but I was feeling weird with the file sizes since it was my first time encoding to such a high quality target. Then I wanted to use 20bit audio but thought it was overkill. But I went overkill on the video, why not go on the audio as well? Also these subtitles, almost 700mb of subs+fonts!? And from a known controversial group! But I can’t find anything better! TwT
So yeah this was the hardest encode I ever did, and actually encoding was not even the hard part lol. But I would be dwelling on these decisions forever if I didn’t settled on something so I just went for it. The audio is not the almost lossless 20bit I wanted, but it is a significant step up from my usual 2.0bps anyway. The subs, as stated previously, feel free to share a better version here, and I might even include them in when the second season BDs show up as a v3.
I do have some things planned for next, but I should probably go re-do Tsugumomo in 1080p because I still have the sources I used and they are using a lot of space…
As usual, my releases are meant to be watched using mpv, preferably on a PC. It probably works on other players as well but that is beyond me.
As someone who works alone (not in any team or group) and is not into any closed circles, it is hard to find things sometimes. If you have something I’m looking for and is willing to share or would like to be encoded but don’t know how to do it yourself or just don’t want to bother with it, you can talk to me via IRC and I can do it for you! I’m not online 100% of the times there but I do eventually show up.

I mean, it is CQ12, which is way higher than what I was used to do. And to think I’ve already released stuff at CQ39 in the past…

Taking into consideration the CQ used and the size of the fonts and subs I’d say it’s still a super reasonable size. Congrats.

should add “bd” in title somewhere so people lookin for bd can just see it right away

Yeah the subs up to episode 7 looks nice, then it goes all down the drain. Thanks though.

Just use Opus - it’s the companion codec for AV1. This is TV anime, you don’t need lossless or near-lossless audio. You aren’t preserving any kind of detail that anyone actually cares about - just wasting bits. Opus also has much broader device/SoC/software support than WavPack.
Also I’ve never heard of 20-bit audio from a commercial source. Commercial sources tend to standardize on 16 and 24 for retail products (32 for mastering work). Did you mean 24? Perhaps you don’t know this, but choosing 16 or 24 has almost zero practical effect on the file size and no audible effect on quality for anime soundtracks or other pop/electronic/“modernistic” music which has a high level of compression done on it in the studio - it has to do with amplitude variable space which is really only applicable to sound engineers working with master tracks, it can also be a factor in very high-tier ($$$$$$$) playback setups for extremely carefully recorded classical, vocal, and jazz works which have a lot of amplitude variation between the noise floor and peak, but outside of that, 24+ bit resolution has almost no consumer application. You are probably getting it confused with the samplerate, which has a huge effect on filesize, but generally doesn’t exceed 48000 Hz for commercial audio sources like anime BDs (for comparison, a standard audio CD is 44100 Hz, while commercially available “studio master” releases can get up to 192000 Hz).
General practice: Match bit depth (16/24) to source. Don’t “upscale” 16 to 24, etc.
I’m also confused by your references to 4.5bps and 2.0bps. Those are HORRIBLE bitrates - those bitrates are worse than what 40 year old space probes can do with radio from out past Pluto. You might want to update your description because it’s VERY confusing to people with professional audio backgrounds like me.
This isn’t an attack. Just genuine feedback for consideration in any future releases you do.

My choice to not use opus is not just to be different, I simply don’t like it, it sounds weird to me. Yes I’ve already done (and still do occasionally) countless testing and it consistently sounds off, whatever trickery it does simply doesn’t go well with me.
Compatibility has never been a concern for me as well, my stuff is meant to be seen using a PC like I always mention, wanting to watch it anywhere else is on the user end, not mine. I mean, if anything the JXL images should be a bigger hassle to deal than the audio itself!
And no, I’m not confusing bit depth with sample rate, even certain profiles for Dolby formats for example can be “optimized” (that’s how they call it, not my own term), which makes them 18 to 21bit depending on the number of input channels and rates. In fact I think I have a BD release of some extra old stuff that has 14bit Dolby audio on it.
It works similarly to WavPack’s pre-quantize bits option which is customizable, but usually used to output 20bit from 24bit inputs, also WavPack can still compress better even on this scenario. Just another way to do lossy WavPack.
I’m not a fan of any tricky lossy codec, never have been, and much prefer the raw mathematical way from things like lossy WavPack, lossyWAV, optimFROG DualStream for example over the tricks that most lossy codecs use, even if that does need higher bitrates. It is a price I am willing to pay for the media I like the most, else I wouldn’t had started processing my own stuff and would just be downloading from others.
I also overtime shifted my quality goals, from trying to go as low as bearable, to as high as I can justify, so no surprises I raised the audio target as well. The current target of 4.5bps is pretty much the end goal though, while I still want to push the video even further (for RAW sources at least).
Edit to fix spelling mistakes*

Just to add, I don’t “upscale” audio by any means, so much so my WavPacks follow the source specs when the source is lossless. For lossy sources I just copy the stream over unchanged.
It’s oddly common that people think I don’t like opus (or lossy in general) because of its sample rates, and although I do confess I don’t love opus resampling everything to 48k, simply because I would rather follow the source, that is not the reason. As I said on the previous message, it’s about how it shapes the sound, the tricks it uses to be alright at such low bitrates. Every lossy codec that uses tricks and psychoacustics I think it’s called, have it’s “flavor”, and once you take notice of it it’s hard not to notice it again.
Its hard to convey what off means though as that’s subjective, if I could I would lend my brain and ears so people could experience exactly the same as I do, and opus people often come down with torches and pitchforks whenever you pick anything else which makes things harder as well, but at the risk of sounding off myself I’ll try:
It’s like as if you arrived back at your house after a day out and everything seemed to be as you left it at first, but as time goes on you notice small, minute things that are ever so slightly different than they should be, and the more you look, the weirder you feel. Or like you expect something to be there, and it looks like it is from afar, but you just can’t shake off that strange feeling. The closer you get, the more you can tell that is not the real deal, like a replica, something that doesn’t belong but tries to.
I know that might sound bizarre, but it is the best way I can describe what “sounding off” means in short terms, for opus at least. Other codecs have their own quirks too.
Note: 4.5bps translates to about 450kbps for standard 2ch BD rates. You’re confusing “bits per sample” with “(kilo)bits per second”
