BlackRabbit Encodes
BlackRabbit focuses on mini encodes made for users who want to save storage space without giving up solid video and audio quality.
Our goal is simple: find the best available remux source, preferably with dual audio (Japanese + English) when possible, and encode it into:
- Video: AV1
- Audio: Opus
This makes the releases especially useful for people running automated setups such as Sonarr, where smaller file sizes can save a lot of storage over time.
Our Encoding Approach
Our releases are more than a straight AV1 + Opus re-encode. We never alter the actual content — no re-timing of dialogue, no cuts, no aggressive filtering by default — but we clean up and reorganize the tracks so every release is tidy, consistent, and behaves correctly across devices and media servers.
The core changes are:
- video is encoded to AV1
- audio is encoded to Opus
- overall file size is significantly smaller
Alongside this, we properly handle the audio and subtitle tracks (details below). The end result is a release that's effectively the same as the source, just smaller, cleaner, and better organized.
Audio Handling
Beyond re-encoding to Opus, we tidy up the audio tracks so they behave predictably:
- Smart bitrates — the Opus bitrate is chosen per channel layout (mono, stereo, 5.1, 6.1, 7.1, all the way up to 7.1.4).
- Logical ordering — tracks are sorted with Japanese first, English second, and any other languages alphabetically after that; main audio always comes before commentary and audio-description tracks.
- Deduplication — redundant tracks are removed, keeping the best source per language and channel layout (lossless preferred, then highest bitrate).
- Optional highest-layout pruning — when enabled, only the highest channel layout is kept per language.
- Optional commentary removal — when enabled, commentary audio tracks are removed.
- Correct flags — default, original, commentary, and audio-description flags are set properly.
- Sync correction — any audio delay/offset baked into the source is corrected so tracks stay in sync.
- Clean track names — messy or inconsistent track titles are cleared.
Subtitle Handling
Subtitles are kept as-is — we don't re-encode or restyle them — but we detect, label, and organize them so the right track shows up at the right time:
- Track classification — every track is identified as Full, Signs & Songs, SDH, Honorifics, Commentary, or Storyboards, including content-based detection for sources with wrong or missing labels.
- Clean, consistent names — e.g.
Full Subtitles,Signs & Songs,SDH, with the source or release group tagged where known. - Correct flags — default, forced, hearing-impaired, commentary, and original flags are set so players automatically pick the intended track.
- Logical ordering — English first, Japanese second, any other languages alphabetically after that; full subtitles before signs & songs; text-based before image-based.
- Deduplication — redundant subtitle tracks are removed.
Source Quality
Source quality is very important to us. If a better remux/source becomes available later, we may re-encode the entire season using that source and increase the version number.
If you know of a better source, please let us know in the comments.
Sonarr Compatibility
Compatibility with automated media systems, especially Sonarr, is one of our main priorities. Because of that, we try to keep file names as Sonarr-compatible as possible to make library management easier and more reliable.
Our Priority
Our main goal is to provide mini AV1 encodes for as many anime as possible while still maintaining good video and audio quality.
When strong AV1 releases from other groups are already available, we would generally recommend using those instead. BlackRabbit's focus is on helping fill the gaps by providing compact, high-quality AV1 encodes across a wide range of titles.
Optional Support
If you would like to support and help us continue releasing mini AV1 encodes, donations are appreciated but never expected.

Feedback is always welcome. If you spot a better source, naming issue, or anything else worth improving, let us know in the comments.

Hey guys, it's been 3 months so I'll just write this here.
I use an Xbox Ally as my daily driver, so I live on a small screen with not a lot of storage. Finding your page has been one of the best things that has ever happened to me!
From the bottom of my heart, thank you to the BlackRabbit team for all your hard work here!
P.S. I think we're missing season 4 of My Hero Academia, lol.
@redblastoise Unfortunately, good quality sources for Seasons 4, 7 and 8 are harder to find on public trackers. In the worst case scenario, we will use the best sources currently available, then release a v2 once better quality sources appear on public trackers.
And yes, we haven’t forgotten about Season 4! 😄
@BlackRabbit look on public trackers that aren't just for anime. You'll find a bd remux
@sk3lp3y We mostly rely on https://releases.moe (SeaDex). SeaDex is maintained by a team that does detailed pixel-peeping comparisons between multiple available releases and recommends what they consider the best source.
They also take subtitle quality into account, including good fansubs, and provide useful information about issues with the source, such as whether debanding is recommended. This saves us a lot of time, since we don't need to perform such detailed source comparisons ourselves for every release.
When SeaDex updates its recommendation because a better source becomes available, we also plan to re-encode the affected release so that our encodes continue to use the best available source.
@BlackRabbit -ZR- release is a JP BD Remux combined with PGS Subtitles and English Audio (likely original or FLAC. Could be also from crunchyroll, but idk). Everything can be found on public trackers.

English Audio - https://nyaa.si/view/1297707 and https://nyaa.si/view/1345849
@sk3lp3y Currently, we don't manually combine video, audio and subtitle tracks from multiple separate releases. Doing that would require us to verify the synchronization of the audio and subtitles against the video for every episode, which would significantly slow down our release pace.
We do re-time audio or subtitles in cases where SeaDex specifically indicates that the recommended source has a known sync issue and provides details about which episode is affected and what needs to be adjusted. In those cases, we can apply the fix without having to manually review the entire release ourselves.
Since our workflow is semi-automated, it is much more practical for us to use the best complete source currently recommended and simply do a re-encode later if a better source becomes available.
@BlackRabbit combining audio and subs can be automated. English Audio and subs need to be delayed by 626ms (compared OP and ED and they both gave the same result). Yes, I did verify by delaying audio and subs by 626ms and muxing them together with the JPBD, and they were synced just fine. Subs from the link i gave which i thought only contains English Audio and not PGS subs turns out to be containing english PGS so no need to grab them from Anime Time's release. Chapters will need to be renamed since they're in russian, but again, that can be automated just like combining or delaying. It's better than nothing, even if you need to spend some time verifying if everything is synced :)
