SubRip, as the name suggests, extracts the timings and subtitles of video files. The resulting file has a .srt extension. These files have a text-based format, and thus, can be edited in most text editors, including Notepad and Wordpad. A SubRip or .srt file is divided into multiple parts. Each of the division has an ID, subtitles, start time and end time, and a blank line. Subtitles refer to the text that should be displayed along with the video. The start and end time indicate the exact time at which the subtitle should be displayed. A blank line is used to shift the control to the next line, from where a new subtitle starts. SubRip files contain a filter too which helps in text extraction and preserving its inline format. This filter also manages the line-breaks between the text. A .srt file is a subtitle type of file format. The following are two examples of files with a .srt extension. In both the above .srt structures, numeric 1 and 2 indicate the ID. The next block contains the start and end time, followed by the subtitle text. Structure I contains simple text with no formatting. However, the text of structure II contains HTML formatting (italic, font color). Consider the start and end time block from structure I. 00:02:17,420 --> 00:02:20,355 The block duration is the difference between these two values, which is equal to 00:00:02,935. In order to run the .srt file along with its video/movie, make sure that both the video file and the .srt file have the same name, and are placed at the same location on your computer. For opening the .srt file on Linux Ubuntu, an application VideoLAN VLC Media Player could be used. Whereas, the programs for opening it on Mac OS X are VideoLAN VLC Media Player, SubCleaner, or any text editor. Since an .srt file works with almost any type of player, simply download the player of your choice and link the .srt file to its respective video file. Remember that a .srt file merely contains text, no video data.
