MicroDVD Subtitle File – file format by Tiamat Software
SUB (MicroDVD Subtitle File) is a subtitle file format developed by Tiamat Software. It is used to store subtitles for MicroDVD, a DVD authoring software. The SUB file contains the subtitle text, the start and end times of each subtitle, and the position of the subtitles on the screen.
Subtitle Files for Video Playback
A SUB file is a subtitle file used for displaying text overlays on video content. It typically contains synchronized timecodes linking specific subtitles to their corresponding video frames. SUB files enable viewers to read dialogue or captions in a different language or to assist those with hearing impairments. Compared to embedded subtitles within video files, SUB files exist as separate text documents that can be easily edited or modified.
Technical Specifications of SUB Files
SUB files adhere to a standardized format that includes a header and subtitle data. The header specifies the number of subtitles and the total duration of the video, while the subtitle data comprises individual subtitles with their start and end timecodes. Each subtitle line may consist of text, formatting information such as font style and size, and references to external bitmap images used for special effects. SUB files are commonly saved using ASCII or UTF-8 encoding, ensuring compatibility with various text editors and media players.
Open SUB Files with Dedicated Software
To open a SUB file, you typically need a dedicated software application that can handle subtitle files. These programs are designed to parse the SUB file’s syntax and extract the subtitle text along with its timing information. Popular subtitle editors that support SUB files include Subtitle Edit, Aegisub, and VisualSubSync. Once installed, you can launch the software and open the SUB file. The program will parse the file and display the subtitle text synchronized with the video it’s associated with.
Other Options for Opening SUB Files
In some cases, you may not have access to dedicated subtitle editing software. Alternatively, you can use some media players that can directly open SUB files. However, this option may have limitations, as not all media players support the SUB format. If you encounter any issues opening a SUB file with a media player, you can try converting it to a more compatible format, such as SRT or ASS, using online tools or conversion software. Additionally, some text editors, such as Notepad or TextEdit, can be used to view the contents of a SUB file, but they won’t provide the same functionality and synchronization features as dedicated subtitle software.
SUB File Format
The SUB file format is a text-based subtitle format used with MicroDVD, a software package for creating DVD-quality videos. It stores subtitle text, timing information, and formatting options in a plain text file. SUB files are typically accompanied by a corresponding media file, such as a video or audio file.
SUB File Structure
SUB files follow a specific syntax and structure. Each subtitle line consists of three main components: the appearance time, the expiration time, and the subtitle text. The appearance time indicates when the subtitle should begin displaying on the screen, while the expiration time specifies when it should stop. The subtitle text is the actual text that appears on the screen. SUB files can also include formatting options, such as font, size, and color, to customize the appearance of the subtitles.
