- Typeset ASS karaoke and animated signs no longer flood the primary overlay, subtitle sidebar, immersion history, or sentence mining with repeated glyph fragments or full-line color phases. Matching timed comments and full-line boundary events recover the complete authored line without merging ordinary repeated dialogue or separately positioned signs, and dialogue spoken while a song's animation is on screen is kept intact instead of being replaced by the lyric. Entrance and exit frames that run past the authored line timing still resolve to the clean line during lyric transitions, and dialogue spoken while a song's animation is on screen enters immersion and subtitle history without the fragment lines beside it. Dense visual grids (sign walls, countdown frames, scattered glyph typesetting) stay out of the published text, while multi-row CC-style dialogue blocks and wrapped lyric rows are still published. Decorative letters that lyric effects render in symbol fonts over the syllables are dropped with the animation instead of corrupting the reconstructed line or leaking as stray cues. Karaoke highlight sweeps that repaint one syllable at a time over an already-visible lyric are suppressed instead of surfacing as rolling partial copies or lone flickering syllables beside the line, and drop-shadow glyph copies offset a few pixels from their base no longer double every syllable in the reconstructed lyric. Positioned word gaps are also recovered on lines where a single fragment carries a literal space, and between wide syllable chunks whose word gap is hidden by their own width, so reconstructed translations keep their spacing instead of running words together.
- The secondary subtitle overlay drops layered duplicate lines from animated tracks, so a short stack of repeated words collapses to its distinct lines even when the full karaoke heuristic does not apply.
