BatuhanYilmaz26/Auto-Subtitled-Video-Generator — reverse-engineered prompt

Build me a simple web app that automatically adds subtitles to videos. I want users to either paste a YouTube link or upload a video file, then the app should detect the spoken language, transcribe it, and create a new version of the video with subtitles burned in.

It should also support uploading an audio file and turning it into transcript files. Let users download the results as txt, vtt, and srt, plus the subtitled video when there is one. If possible, include two modes, one that keeps the original language and one that translates the speech to English before making the transcript.

Make the interface friendly and visual, with the original video and subtitled video shown side by side after processing. Use Python with a lightweight web UI, Whisper for speech recognition, YouTube downloading for links, and ffmpeg for generating the final subtitled video. Include setup instructions and make it easy to run locally or deploy.
