Format Details
ASS
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.
VTT
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.
