Could you build this?
Partial A browser timeline editor is vibe-codeable, but smooth 4K export and fully on-device AI subtitles and voiceover require performance-heavy media and ML work in WebAssembly or WebGPU.
What it would actually take: The stack would combine a timeline UI with WebCodecs or ffmpeg.wasm for encoding and a local speech model such as whisper.cpp compiled to WASM. Making 4K export and transcription fast enough in the browser takes media-engineering expertise and careful memory management.
