This Python script auto-dubs Hindi videos into English using AI. It extracts the audio, transcribes dialogue with Whisper, translates into English using NLLB-200, and generates natural-sounding AI speech with Bark. The dubbed voice is synced via timestamps and merged into a resized 480p video for smooth, accessible playback.
