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, [15] colors and video processing requirements [16] to recognize subtitles.

DirectVobSub/VSFilter were formerly part of a whole application known as VobSub which was also able to extract subtitles from DVD Video and create text-based subtitles, without ripping the DVD to a file first. The last version of VobSub was version 2.23, after which the development of VobSub ceased.

"Soft" subtitles, or soft subs , are subtitles applied at playback time from a subtitle datafile, either mixed directly into the video file (.mkv, .ogm, etc.), or in a separate file (.ssa, .srt, etc.).
A subtitle editor is a type of software used to create and edit subtitles to be superimposed over, and synchronized with, video. Such editors usually provide video preview, easy entering/editing of text, start, and end times, and control over text formatting and positioning.
In October 1999, DeCSS was released. This program enables anyone to remove the CSS encryption on a DVD. Although its authors only intended the software to be used for playback purposes, [2] it also meant that one could decode the content perfectly for ripping; combined with the DivX 3.11 Alpha codec released shortly after, the new codec increased video quality from near VHS to almost DVD ...

A value of zero for the PES packet length can be used only when the PES packet payload is a video elementary stream. [6] Optional PES header: variable length (length >= 3)
A video file format is a type of file format for storing digital video data on a computer system. Video is almost always stored using lossy compression to reduce the file size. A video file normally consists of a container (e.g. in the Matroska format) containing visual (video without audio) data in a video coding format (e.g. VP9 ) alongside ...
