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

We generally do not make unnecessary changes. The aim is to keep everything as close to the source as possible, with only these main differences:

• video is encoded to AV1
• audio is encoded to Opus
• overall file size is significantly smaller

In other words, the release should remain effectively the same as the source, just in a more storage-efficient format.

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.
