Extract and translate video subtitles fully on macOS with TransSub: feed a local video file, get a time-accurate SRT plus a translated SRT using whisper.cpp (Metal GPU) for transcription and Ollama or an OpenAI-compatible API for translation. Use when the user is on Apple Silicon / Intel macOS and wants privacy-safe, local-first subtitling for MP4/MKV/MOV/AVI without uploading the video, including configuring Whisper bin/GGUF models, optional VAD, dual original/translated SRT output, and switching between local Ollama and remote OpenAI-compatible / OpenRouter endpoints.
