SRT (SubRip Text) is the most universal subtitle format. The format is simple text: each subtitle block has a sequence number, a time range (00:00:01,000 --> 00:00:04,000), and the subtitle text. Key details: timestamps use comma (,) not dot (.) as decimal separator; maximum 2 lines per subtitle is recommended; maximum ~42 characters per line for readability. Our generator produces properly formatted SRT with timing, line breaks, and UTF-8 encoding for international characters.
