Release

Encoded in AV1 and OPUS for higher size and quality. Files are named to support media servers like Plex using TVDB metadata.

Encoding Details:

We rescaled the JPBD via VapourSynth using ArtCNN and encoded with our SWAN system to target a SSIMULACRA2 score of ~90.

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

The header above links to the comparison between the JPBD, the rescaled JPBD, our SavI0r HEVC release, our resulting AV1, our smaller SavI0r AV1 release, and the closest HEVC mini from OTR. Below are a few of the comparisons between the JPBD, our HEVC release, and this release.

Statistical Image Comparison Analysis:

We measured the SSIMULACRA2 score for every frame in S01E01 and then plotted them into a histogram for some rudimentary statistical analysis. We also included a line graph showing the average score for each scene. Those can be accessed here and viewed below. Note that the scenes with excessive noise in the source never score well in SSIMULACRA2. The scenes in the ending demonstrate the extreme optimizations developed for this particular release in order to curtail bitrate. Without developing those optimizations, most of those ending scenes would be ~30mb each, resulting in a file twice as large. You can see comparisons of some of these scenes (19-22) linked above.
