Note: Been working for three whole months on this show. I’ve been meaning to make two quality variants since the beginning, from tests I started doing all the way back when the first BD volume came out. I saw pretty quickly this source would be challenging, but I think the results ended up great! This release is the higher quality version of the usual [Trix] release. Otherwise, everything else is the same between the releases. See y’all for season 2!
Video Comparison: BDMV vs Trix (BD Thicc) vs Trix (BD Mini) vs Trix (WEB)

Tired of VLC acting up with Opus audio, with subtitles, with color rendition? We recommend the MPV media player for the best playback experience (TheWiki Guide). Always keep your software up-to-date!
