What it does
Whisper and similar models make speech-to-text highly reliable. Video processing and subtitle burning are well-documented workflows. The main challenge is handling large video files and processing time, but the core feature set is very buildable.

Build a web app where users upload video files (MP4, MOV). Use Whisper or a similar speech-to-text API to transcribe the audio with timestamps. Display the video with an editable subtitle timeline. Allow users to choose subtitle styles (font, color, position, animation), edit transcript text, and export as SRT, VTT, or burned-in video. Add bulk upload for course creators and auto-translation into 10+ languages.
