SubRip is a software program for Windows which "rips" (extracts) subtitles and their timings from video. It is free software, released under the GNU GPL. SubRip is also the name of the widely used and broadly compatible subtitle text file format created by this software. Using optical character recognition, SubRip can extract from live video, video files and DVDs, then record the extracted subtitles and timings as a Subrip format text file. It can optionally save the recognized subtitles as bitmaps for later subtraction (erasure) from the source video.
