> This project is a production with the goal of the smallest video size with moderate subjective compromises to image quality. This is not the hallmark of AV1, but close enough. This release should only contain changes to the video stream and audio tracks. The subtitle and attachment tracks are usually copied from the noted sources. Timings are not adjusted except in cases of extreme delay as a result of mixing sources. - `SavI0r`
### [**Comparisons**](https://slow.pics/c/2ZM1Rtod "S01E01")
The header above links to a comparison of S01E01 between the [JPBD][source-anti], the same JPBD rescaled, [Lulu][source-lulu], [Judas][comp-judas] as the closest mini encode, and our resulting AV1. Below are a few comparisons between the [JPBD][source-anti], [Judas][comp-judas], and our AV1.

## Comment Commentary
@Simplistic: Apologies for the mistake in the description. For clarification, the JA audio is 3 channels (2.1) - likely similar to the Girls und Panzer release which contains an LFE channel in addition to the standard stereo channels - and it's encoded with opusenc to 160kbps. There are also JA commentary audio tracks (stereo 2.0) included and those are encoded with opusenc to 64kbps as they are primarily dialogue. EN audio is only available in stereo (2.0) and it's encoded with opusenc to 128kbps. The RU audio source is **not** official and the quality does not match up to the other sources so it's encoded to our minimum of 96kbps.
Besides the RU audio, we set the parameters for encoding Opus audio roughly based on research from [here](https://wiki.hydrogenaud.io/index.php?title=Bitrate#Equivalent_bitrate_estimates_for_multichannel_audio). For releases unlike this one, we use the default 96kbps for stereo. Due to the nature of the story/content, we intentionally went with the higher 128kbps stereo - which is considered transparent for most people. For the additional LFE channel we bump up the bitrate to 160kbps. For 6 channel (5.1 surround) and 8 channel (7.1 surround) releases we use 256kbps and 320kbps respectively.
We provide the mediainfo for a single file representative of the entire release linked in a header above labeled "Media Info" and it corroborates the information laid out earlier. Additionally, you can check the mediainfo of *any* file in this release - and many others - from AnimeTosho [here](https://animetosho.org/view/savi0r-heavy-object-bd-1080p-av1-opus-multi-dual-audio.n1929567).
Have a nice day,
