In simple English
VideoCaptioner takes an ordinary video file and generates matching text subtitles for it. It listens to the speech, chops it into readable lines, translates it into another language, and burns the result directly onto the video. Some basic speech engines and translation services are free to use without any setup. If you want advanced text cleanup or translation using large language models, you need your own paid API key. The program runs on your computer and requires Python to install via the command line, though Windows users can download a pre-built package.
What it is
VideoCaptioner is an open-source video subtitling assistant powered by speech recognition and language models. It handles the complete workflow from raw audio transcription and sentence breaking to translation and video synthesis.
