subtitles: Generate and Render Timed Subtitles Using 'FFmpeg'
Tools for generating timed subtitle files and rendering them into video with the 'FFmpeg' command-line interface (<https://ffmpeg.org/>). Converts structured transcription output (such as that produced by 'Whisper' speech-to-text models) into SubRip ('SRT') and Advanced SubStation Alpha ('ASS') subtitle files, with word-level caption timing, styling presets, and line-break control, and burns subtitles into video files using the 'FFmpeg' subtitles filter.
