michael b11c3d0d4f fix: rewrite VTT retiming algorithm to prevent captions during AD segments ... The VTT retimer had two bugs causing subtitles to display during freeze periods and become out of sync: 1. Same offset applied to both start and end times (should differ when pause falls between them) 2. Cues spanning pause points weren't split (causing captions during freeze) Changes: - Add _offset_at() for timestamps AT or AFTER pause points - Add _offset_before() for timestamps STRICTLY BEFORE pause points - Add _retime_cue() to split cues at pause points into multiple segments - Add _filter_short_segments() to remove <100ms segments after splitting - Rewrite retime_for_pause_insert() to use new helper methods Example fix for cue 8s-12s with pause at 10s (4s freeze): - Before: 8s-12s (displayed during freeze!) - After: 8s-10s + 14s-16s (gap during AD) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>		2025-12-30 09:01:03 -06:00
