ASS (Advanced SubStation Alpha) is a feature-rich subtitle format supporting sophisticated text styling including custom fonts, colors, borders, shadows, precise on-screen positioning, and karaoke timing effects. It is the dominant format for anime fansubbing and professional subtitling where fine-grained typographic and positioning control is essential. ASS subtitles can include multiple simultaneous text layers and complex motion effects.

LRC is a plain-text lyrics format that timestamps each line of song lyrics for karaoke-style display. Players show the current lyric as the audio reaches each tag. LRC files are easy to edit and convert to common subtitle formats like SRT and VTT.

MPL2 is a simple subtitle format used primarily by the MPlayer and MPV media players on Linux systems. It stores subtitle timing in units of 1/10 second and subtitle text in a compact, line-based plain-text structure without formatting codes. MPL2 is lightweight and easy to generate programmatically, making it suitable for basic subtitling where advanced formatting is not required.

SRT (SubRip Subtitle) is the most widely used and compatible subtitle format on the internet, originating from the SubRip DVD ripping software. It stores subtitles as sequentially numbered blocks, each containing a start/end timestamp and one or more lines of display text. SRT files are plain text, easily editable with any text editor, and supported by virtually every media player, video editor, and streaming platform that handles subtitles.

SSA (SubStation Alpha) is the predecessor to the more capable ASS format, offering more styling options than SRT while being simpler in structure than ASS. It supports custom fonts, colors, positioning, and basic animation effects, and was the standard subtitle format in anime fansubbing communities before ASS gained prominence. SSA and ASS files share a similar file structure and are often treated interchangeably by modern media players.

SUB (MicroDVD Subtitle) is a subtitle format that stores timing as video frame numbers rather than absolute timestamps, making it intrinsically frame-rate dependent. Each subtitle entry uses curly-brace notation for frame numbers and supports basic inline formatting. SUB is a legacy format from the DVD ripping era that is still supported by major media players, though SRT and VTT have largely replaced it for new subtitle content.

VTT (WebVTT, Web Video Text Tracks) is the W3C-standard subtitle and caption format for HTML5 video, designed to work natively in web browsers without plugins. It supports text cues with precise timing, multiple text tracks, and CSS-based styling for rich caption presentation. VTT is the required format for closed captions on web video platforms, streaming services, and accessibility-compliant applications.
