MicroDVD is a subtitle file format for digital video. Its name is derived from 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.

Format

MicroDVD subtitle files have .sub filename extensions. These files may come along with a video file. Media player applications that support external subtitle files are responsible for locating correct .sub files.

MicroDVD subtitle files consist of multiple lines, each defining a portion of the subtitle text that must be displayed between certain given video frames. The line syntax is:

{start-frame}{stop-frame}Text

For example, if "Hello!" is to be displayed during the first 25 frames of a digital video, clip or movie, the corresponding .sub file must contain the line:[1]

{0}{25}Hello!

The duration of the text being displayed depends on the frame rate of the corresponding video file. For example, if the frame rate of the corresponding video file is 25 frames per seconds and the subtitle file in last example is accompanied with, "Hello!" is displayed for one second.

The font size cannot be configured in .sub files, only in player, but the font style of the subtitle displayed may be changed:

{0}{25}{y:i}Hello!

"Hello!" is displayed in italic.

{0}{25}{y:b}Hello!

"Hello!" is displayed in bold.

{0}{25}{y:u}Hello!

"Hello!" is underlined.

{0}{25}{y:s}Hello!

"Hello!" is stroked.

{0}{25}{C:$0000ff}Hello!

"Hello!" is displayed in red. The color format is: $BBGGRR (8 bits blue, 8 bits green and 8 bits red). Note that this is not standard RGB color model.
