The quality of the original disk in the S1 was around average...It can be seen that the original resolution is relatively low, and the Blu-ray quality is not among the best.
Pre-processing includes mild anti-aliasing and grain stabilization, and then the parameter sets the upper limit of the bitrate for the scene of the heavy grains.
Reseed comment:
1. From the perspective of picture quality, the original picture quality of volume version of Date A Live S1 is better than its BDBOX of director's cut version (which was debanded by official brutally). That's why we reuploaded the volume version's BDRip for reseeding.
2. For the correction issue, we renamed the SP and removed music and scanned pictures (and please get these contents from the collection that we reuploaded several days before of the series).
