The Shawshank Redemption is a film of quiet tension and literary dialogue. A bad subtitle file ruins the poetry of "Hope is a good thing" or "I guess it comes down to a simple choice."
This is the most important technical step. Your video file has a specific "hash" or "release name" (e.g., The.Shawshank.Redemption.1994.2160p.BluRay.REMUX.DTS-HD.MA.5.1-FGT ).
