v1.3.3

Highlights

• Added full voiceover preview with estimated duration before video generation. Preview audio can be reused when the final generation settings remain unchanged.
• Added optional video-matched background music generation through Sonilo and ElevenLabs, with graceful fallback when music generation fails.
• Added custom background music uploads directly from the WebUI.
• Added a global video clip speed control and new ZoomIn / ZoomOut transitions.
• Added lightweight, non-blocking update notifications in the WebUI.
• Hardened task execution and recovery across the WebUI, API, and CLI, with clearer stage and error tracking.

Fixes and Improvements

• Fixed Windows portable-package startup failures caused by conflicting Python app packages.
• Fixed the WebUI becoming blank after starting video generation.
• Preserved generation progress, logs, and terminal task states across Streamlit reruns.
• Improved interrupted-task recovery and kept social publishing failures independent from successful video generation.
• Added queue limits and more reliable state updates for cross-platform publishing.
• Prevented unexpected Whisper model fallback when another subtitle provider fails.
• Fixed LLM provider errors being passed into material keyword generation.
• Fixed repeated cleanup attempts for the same temporary video file.
• Allowed video materials that fall only a few pixels below the nominal minimum resolution because of encoder rounding.
• Standardized TTS API key links and provider setup guidance.
• Completed missing secondary translations across supported WebUI languages.
• Added line-ending normalization for more consistent contributions across Windows, macOS, and Linux.
• Expanded CI coverage for task execution, API controllers, media handling, queues, application startup, and failure recovery.
