This project is a production with the goal of the largest video size with minimal subjective compromises to image quality. This is not the hallmark of anything whatsoever. This release should only contain changes to the video stream tracks. The audio, 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 resulting release, our SavI0r-Pro AV1 release of similar quality, our smaller SavI0r AV1 release, and the closest HEVC mini from OTR. Below are a couple of the comparisons between the JPBD 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. Ignore the CRF data in the line graph, it only references the CRF used in our AV1 release. We used this data to determine the quality target for our SavI0r-Pro releases.
