The most important step is matching the subtitle file to your specific video file (often named something like Charlie.and.the.Chocolate.Factory.2005.1080p.BluRay.x264 ).
: If they are way off, try downloading a different version from the subtitle site that matches your video's "Rip" (e.g., BluRay vs. WEB-DL).
Right-click your movie file and select , then copy the name.
