Styled Subtitle Studio

An Advanced SubStation Alpha (.ass / .ssa) visual style designer, karaoke syllable timing splitter, video frame typesetter, and Matroska softsub muxer for Linux.
A lightweight Linux alternative to Aegisub for ASS subtitle styling, karaoke syllable typesetting, and soft-subtitle mastering.

Key features powered by bundled FFmpeg:
- Interactive [Events] dialogue and override tag editor supporting layers, centisecond timestamps, \pos(X,Y) coordinate placement, \c color overrides, and \fs font scaling.
- Karaoke syllable timing splitter generating proportional {\kf} smooth-sweep and {\k} highlight tags with per-syllable centisecond inspection.
- Visual [V4+ Styles] designer controlling font family, size, primary/karaoke/outline/shadow colors, bold/italic attributes, border & shadow depth, 9-point alignment, margins, and live swatch preview.
- Live styled subtitle compositor rendering [V4+ Styles], \pos placement, and progressive karaoke sweeps onto real decoded video frames, plus PNG frame export.
- Bidirectional ASS <-> SRT format conversion, embedded subtitle extraction, and lossless Matroska (.mkv) softsub multiplexing.
