ffmpeg-analyse-video

Extract frames from video files with ffmpeg. Delegate frame reading to sub-agents to preserve the main context window. Synthesise a structured timestamped summary from text-only sub-agent reports.

Problem: Reading dozens of images into the main conversation context consumes most of the context window, leaving little room for synthesis and follow-up.

Images only ever exist inside sub-agent contexts. The main agent only reads lightweight text files. This cuts context usage by 90%.

Analyse video content by extracting frames with ffmpeg and using AI vision to generate timestamped step-by-step summaries. Use when user provides a video file and wants to understand its visual content — screen recordings, tutorials, presentations, footage, or animations. Triggers on "analyse this video", "what happens in this video", "summarise this recording", or any request involving understanding video file contents. Source: fabriqaai/ffmpeg-analyse-video-skill.
