A massive database where you can filter by "BluRay" and "720p" to find the most compatible file.

If you are using VLC Media Player , you can simply drag the subtitle file into the player window while the movie is running.

If the dialogue doesn't match the audio, use the 'G' (delay) and 'H' (speed up) keys in VLC to adjust the timing manually.

For your media player (like VLC or MPC-HC) to load the subtitle automatically, rename the .srt file to match the video file exactly (excluding the extension). Video: Contracted.2013.720p.BluRay.x264-PFa.mkv Subtitle: Contracted.2013.720p.BluRay.x264-PFa.srt
