Description
SubStation Alpha (ASS) is a text-based file format used for subtitle files. It is mostly used for anime, but can be used for any type of video. It is a plain-text format and can be opened with any text editor, such as Notepad. It allows for the creation of more complex subtitles than plain text, such as color-coding, formatting, and timing.
MicroDVD is a subtitle file format for digital video. Its name is derived from the MicroDVD Player, a media player application designed to play DVD videos along with subtitles, originally developed by Tiamat Software. The application was first released in 2000 but development ended in 2001. Media players that support the format are able to interpret MicroDVD subtitles and mix their contents with their corresponding video files.
