This release includes Monogatari Series Second Season Blu-ray Episodes along the audio commentaries that came with the Blu-rays/DVDs and it's translation.
Encoded to 10-Bit (x264) to reserve space while maintaining quality.
Source: Balwant from Hi10 via Coalgirls
Audio Commentary Translation: r/araragi - maxdefolsch & ValanL
Since Coalgirls release was OCed, I have rejoined the parts and muxed everything together into one file for each episode.
The result is a great balance of 'quality/file size' with two audio tracks (Original + Commentary), and two subtitle tracks (Coalgirls Subs + Commentary via maxdefolsch & ValanL)
Koimonogatari isn't from Hi10, since their OC release would pose problems while joining the parts, so I used another release (Kayoanime), that still used Coalgirl's subtitles, found in this Google Drive:
