Description

Reason for Remake

I originally released a copy based on a lower quality release, and it was noted by SeaSmoke, who brought it to my attention. Thanks mate. He also pointed out that Z4ST1N had released a vastly superior version, though a BluRay is due some time soon as well.

Cleo; Ember, and Judas have all released complete batches of this Anime, but I wanted to add an alternative with a higher bitrate, and to use different audio codecs.

I've taken the Video; Japanese Audio and Subtitles from Z4ST1N's version; re-encoded the video to HEVC 10-bit, and combined them with the English audio from Golumpa's - putting them into a single file for convenience, and renamed ready for Plex/Emby/Jellyfin.

NOTE: Source English audio was AAC; converted to WAV for editing, then transcoded to Opus

Work Carried Out

  • Extracted content from both releases
  • Realigned English audio to match Japanese audio timing
  • Edited English audio, splicing in missing parts from the Japanese audio
  • Normalized both completed audio tracks
  • Exported both audio tracks to WAV
  • Converted the both audio tracks to Opus
  • Transcoded video to HEVC 10-bit using CPU (no hardware transcoder) @ CRF:16
  • Combined the Japanese audio; English audio; English subtitles and video track into an MKV

Thanks to Golumpa; Z4ST1N; SeaSmoke; LostYears and everyone else involved.

Also, cheers to all the people involved in creating the Anime. Please, if you enjoy the Anime, consider supporting them directly by purchasing the Anime :)

why would you do this?

I needed to edit the audio anyway as there were parts missing as well as out of sync voices, and doing it in WAV format is the best possible option. I could have compressed it to FLAC afterwards, but the size was too large. In the end, I decided that if I'm going to re-compress the audio with a lossy codec, why not use one that is arguably superior to AAC?

There's an old guide/comparison here about using FLAC in a rip, and I tend to agree with the results. FLAC is nice, but Audiophile perfection is not what I was going for, considering the sources available. If I had a BluRay rip to work from, it might be a different story. In sort, I'm going for reasonable file sizes, with good quality audio - based on what was available at the time. AAC English and AAC/FLAC Japanese are all that were available at the time I was working on this.

Ultimately, I'm only working with what I have :)

you can cut lossy audio without re-encoding it rather easily with tools like this for avisynth or this for vapoursynth by lining up the two video sources so the frames match exactly all throughout the video. in fact, it sounds like that's exactly what your problem was with one having more or less frames where commercials would be or whatever. what you did involves encoding lossy audio to lossy again, which lowers quality greatly for no reason. and yes, before you complain, you can do extremely complicated stuff with these tools if you use them right. as long as all the audio is the same sample rate/codec and for the same FPS video (which is almost always should be). there's really no reason to re-encode lossy audio ever.

No complaint, none at all. I'm willing to concede your point that re-encoding a lossy format is not a great choice. However, the tools you mentioned are not capable of things like Crossfades; Fadeouts; Normalization; EQ; Noise removal; Waveform Repair; Compressors and filtering, which all play into the work I've done. I mean, if you don't like what I've done, that's quite alright. I understand that what you're saying isn't personal, and is just meant to point out how it could be better.

I made the release with my own personal preferences in mind. I do appreciate the feedback though, and I will try harder to meet your standards in the future, if I release anything else :)

You're free to download an alternative version by one of the groups/people I mentioned above. They're all great releases in their own right!

that's true, it can't do any of those things. but you also should never need to do any of those things. most people want the audio to sound like the anime studio intended, not have your "edits."

except there's no way they'd know from your description that you "improved" the audio, is there?

The "Work Carried Out" section is there. Tell me, what should I add that would meet your requirements to differentiate my release from anyone else's that isn't already listed?

If your change is a reasonable one, I'm happy to add it :)

@D44 - Oh? In what way? Can you explain the details of the issues? At least if I know what's wrong with it, I might be able to improve it next time around. Thanks!
