To address this challenge, I designed and implemented an automated AI-Powered Video Dubbing Pipeline that translates and localizes foreign-language video content (such as Chinese) into Hindi with precise sync accuracy. The system operates on a modular 3-stage architecture: first, FFmpeg isolates and splits raw video input into independent audio and visual streams; next, a timestamp-aligned Speech-to-Text model extracts dialogue into accurate, time-synced subtitles before translating them into localized target-language text; and finally, a Neural Text-to-Speech synthesis model generates the Hindi audio output, which is re-merged with the original video track using FFmpeg. Built using Python, modern AI models, and custom media processing workflows, this system replaces manual dubbing with an end-to-end automated process, significantly reducing content creation overhead and serving as a scalable solution to democratize multimedia access for non-native language speakers.</p> ai python machinelearning webdev
