About ASS
Advanced SubStation Alpha
Version 4+ of the SubStation Alpha script format, used by Aegisub and anime fansubbing, with styles, fonts, positioning, karaoke timing and effects. Use it when captions need precise styling or placement; convert to SRT for players that ignore those features.
About VTT
WebVTT
Web Video Text Tracks, the W3C caption format for the HTML track element. It looks like SRT but adds cue positioning, styling and metadata. Use it for captions on web video players, which read WebVTT natively.
