 ## Version 2.0: SSIMULACRA2-based
 
 > Does a fast encode of the provided file, calculates SSIMULACRA2 scores of each chunks and adjusts CRF per-scene to be closer to the average total score, in a _zones.txt_ file to feed Av1an.
-The requirements are Vapoursynth, vstools, LSMASHSource, Av1an and vapoursynth-ssimulacra2.
