Ass To Srt

Calculators REST API MCP

Flatten an Advanced SubStation Alpha (.ass) or SubStation Alpha (.ssa) subtitle script to plain SubRip (.srt). Reads the Dialogue lines of the [Events] section using the Format line for column order, converts H:MM:SS.cc centisecond timestamps to HH:MM:SS,mmm, strips every {\...} override block, turns \N into a line break, sorts cues by start time and renumbers them from 1. Styles, fonts, colours, positioning and drawing commands are discarded on purpose, because SubRip cannot carry them. Comment lines are ignored.
