🚀 Overview

Version 1.3.0 completely transforms the application from a linear, forward-only generation script into an interactive, non-linear Subtitle Workstation. Users can now review, proofread, and batch-edit their translations directly inside the browser canvas before exporting perfectly aligned subtitle files.

💎 Key Features

⏱️ Interactive Subtitle Review Timeline

  • Visual Workspace: Added a beautifully styled, scrollable timeline view in the right-hand panel that populates instantly upon pipeline completion.
  • Frame-Accurate Alignment: Fixed critical positional parameter issues within the background worker to ensure WhisperX forced-alignment syncs acoustic phonemes flawlessly, yielding millisecond-accurate timecodes.

✍️ Inline Card Editing & Auto-Save

  • WYSIWYG Word Processing: Turned static text blocks into live editing fields using HTML5 contenteditable.
  • Zero-Interruption Sync: Implemented an asynchronous background saving pipeline (PATCH /videos/{id}/segments/{sid}). Modifying a word and clicking away seamlessly updates the local SQLite database without locking up the user interface.
  • Safe-Fail Guards: Introduced an empty-string discard filter. If a line is accidentally wiped out, the UI safely restores the original text block to prevent timeline data corruption.

🔍 Global Find & Replace Console

  • Batch Terminology Correction: Added a sleek, high-efficiency utility bar at the top of the timeline panel to sweep and replace systemic AI translation errors across the entire video file in milliseconds.
  • Race Condition Prevention: Built a global execution lock state that blocks duplicate double-clicks and gracefully manages concurrent processing between manual card saves and batch text overrides.

🎨 UI/UX Refinements

  • Decluttered Workspace: Stripped away the legacy, pre-translation "Custom Terms" override grid to streamline the desktop layout.
  • Progressive Disclosure: The project setup panel (languages, engine keys) now automatically collapses when processing starts to leave a clean, focused log and terminal view.
  • Intelligent Toast Notifications: Eliminated noisy pipeline spam and reintroduced targeted, high-layer (z-[9999]) visual confirmation popups specifically for user editing actions.
  • Persistent History Logs: Step durations and pipeline timestamps now remain perfectly intact inside the activity monitor across pipeline phase transitions.
  • Air-Tight Hydration: Fixed state restoration on browser page reloads. Refreshing a completed project now immediately hydrates the full timeline grid and context brief perfectly from the URL state.

🛠️ Under the Hood

  • Optimized SQL performance utilizing SQLAlchemy's selectinload() strategy to eagerly package segment payloads in a single database round-trip.
  • Added soft-degradation fallbacks to the transcription service, cleanly routing critical external environment or package exceptions into handled user logs without freezing the job queue.
