 `video-subtitle-translator` is an Agent Skill [built with oo CLI](https://oomol.com) for turning local audio and video into timed captions, translated subtitle files, hard-subtitled MP4s, or videos with selectable subtitle tracks. It combines Alibaba Qwen ASR transcription with deterministic subtitle processing, so the output is ready for sharing rather than a loose block of transcript text.
