All computation is performed directly on the client machine:
- WebAssembly (FFmpeg.wasm) for high-throughput video demuxing, decoding, and encoding
- WebCodecs API for hardware-accelerated local frame processing
- Whisper WASM / Transformers.js for on-device speech recognition & captioning
- Web Streams API for zero-memory-leak local file manipulation
Zero video files or personal data are ever uploaded to a server.
