Thanks for flagging -- this seems to be a common point of confusion; I'll work on updating the readme. Let's say reference.srt is a set of English subtitles, and you have an out-of-alignment French subtitles file unsynchronized.srt. You could use the video directly as a reference in order to synchronize the French subtitles, but it will take a bit longer since we need to extract audio and perform voice detection over the whole video file. In this case, it will be faster to use your already-synchronized English subtitles file reference.srt.
