Build a professional AI-powered video dubbing application called **LingoDub Studio**. ### Core Features 1. Allow users to upload **MP4 and other common video formats**. 2. Automatically detect the video's **source language**. 3. Let users select a **target language** from 170+ supported languages. 4. Transcribe the entire video from beginning to end with accurate **timestamps and speaker identification**. 5. Detect speaker changes and support **20+ different speakers/characters**. 6. Translate every dialogue naturally while preserving the original meaning, context, emotion, and timing. 7. Generate natural-sounding dubbed voices with different **male/female voices, accents, emotions, and speaking styles**. 8. Allow optional **voice cloning from an uploaded voice sample**, where supported. 9. Preserve the original **background music, sound effects, ambience, and cinematic audio**. 10. Separate dialogue from background audio before dubbing, then mix the new dialogue with the original background. 11. Synchronize dubbed speech with the original video's timing as closely as possible. 12. Keep the original video quality and resolution. 13. Provide **subtitles/captions** with the option to enable, disable, or edit them. 14. Provide an **audio/voice editor** where users can change speaker voices, volume, timing, emotion, pitch, and speed. 15. Process the **entire uploaded video**, not just a short sample. 16. Show processing progress and clear error messages. 17. When dubbing is complete, provide a separate **Dubbed Video** output that users can preview and save. 18. Make sure the final video has both **working video and audible dubbed audio**. ### UI Create a clean, modern, professional interface with: * Upload Video button * Video preview/player * Source Language * Target Language * Speaker Detection * Voice Selection * Voice Cloning * Subtitle Settings * Audio Mixing * Voice Editor * Start Dubbing button * Processing progress bar * Original Video and Dubbed Video sections * Download/Save output button Use a scalable architecture so additional AI models, languages, voices, and video-processing features can be added later. Use reliable speech-to-text, translation, text-to-speech/voice-generation, speaker-detection, audio-separation, and FFmpeg-based video/audio processing services. Handle long videos efficiently and never silently drop the original video or dubbed audio.
