Video Analyser Skill

Analyse a video file to extract bugs, errors, UI state, and reproduction steps. The pipeline uses ffmpeg for frame extraction, optional tesseract OCR for text, and optional whisper for audio narration. The default path (8 keyframes at 768 px) is the Pareto-optimal setting for screen recordings: best quality-per-token on the legibility curve.
