bsisduck/video-analyzer-skill ? reverse-engineered prompt

Build me a Claude Code skill for analyzing videos from the command line.

I want to be able to point it at a video file and have it automatically figure out a sensible sampling rate, extract frames, detect scene changes, pull audio, and optionally transcribe it with Whisper if it is available. It should handle common video files like mp4, mov, avi, mkv, and webm, and it should be smart enough to ignore weird thumbnail streams sometimes found in downloaded social videos.

Please make it support custom frame rates and time ranges too, like analyzing just part of a clip or doing a faster or slower pass. It should create a clean Markdown report with a timeline, scene breakdown, and a useful summary of what is happening visually and in the audio.

I also want the scripts to work on their own outside Claude Code, with simple shell commands, and include the skill files and reference notes needed to use it properly. If you need to check current ffmpeg or Whisper docs online, go ahead.
