Because movie releases have different timings (frame rates, introductory logos), you must use a subtitle file synced specifically for the release.
: If the text appears before or after the audio, use VLC's synchronization tools. Press 'H' to delay the subtitles or 'G' to hasten them in 50ms increments.
: Rename the downloaded .srt file to match your movie file exactly: Movie: Vantage.Point.2008.720p.BluRay.x264.YIFY.mp4 Subtitle: Vantage.Point.2008.720p.BluRay.x264.YIFY.srt
