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. SubRip softwareUsing 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.[3] It can optionally save the recognized subtitles as bitmaps for later subtraction (erasure) from the source video.[4][5] In practice, SubRip is configured with the correct codec for the video source, then trained by the user on the specific text area, fonts, styles,[6] colors and video processing requirements[7] to recognize subtitles. After trial and fine tuning, SubRip can automatically extract subtitles for the whole video source file during its playback. SubRip records the beginning and end times and text for each subtitle in the output text SubRip uses AviSynth to extract video frames from source video, and can rip subtitles from all video files supported by that program. The SubRip file format, as reported on the Matroska multimedia container format website, is "perhaps the most basic of all subtitle formats."[9] SubRip (SubRip Text) files are named with the extension
Example: 168 00:20:41,150 --> 00:20:45,109 - How did he do that? - Made him an offer he couldn't refuse. FormattingUnofficially the format has very basic text formatting, which can be either interpreted or passed through for rendering depending on the processing application. Formatting is derived from HTML tags for bold, italic, underline and color:[10]
Nested tags are allowed; some implementations prefer whole-line formatting only. CompatibilityThe SubRip The SubRip format is supported directly by many subtitle creation/editing tools,[12] and some hardware home media players.[13][14][15][16][17] In August 2008, YouTube added subtitle support to its Flash video player under the "Closed Captioning" option - content producers can upload subtitles in SubRip format.[18] WebVTT{{Main article|WebVTT}}A format originally called WebSRT (Web Subtitle Resource Tracks) was as of October 2010 being specified by the Web Hypertext Application Technology Working Group for the proposed HTML5 The prospective format was later renamed WebVTT (Web Video Text Track).[21][22] Google's Chrome and Microsoft's Internet Explorer 10 browsers were the first to support {{tag|track|o}} tags with WebVTT files for HTML5 videos. Mozilla Firefox implemented WebVTT in its nightly builds (Firefox 24), and as of Firefox 31 (July 24, 2014), Mozilla enabled WebVTT on Firefox by default.[23] The feature had to be enabled in Firefox by going to the "about:config" page and setting the value of "media.webvtt.enabled" to true.[24] YouTube began supporting WebVTT in April, 2013.[25] Text encodingSubRip's default output encoding is configured as Windows-1252. However, output options are also given for many Windows code pages as well Unicode encodings, such as UTF-8 and UTF-16, with or without Byte Order Mark (BOM). Therefore, there's no de facto character encoding standard for A number of embedded hardware-based players only have support for ASCII or Western European fonts due to the licensing costs associated with the commercial fonts used {{Citation needed|date=June 2017}}.
