drawing-video

Footage in, narrated comic strip out. Five stages: probe → ground → narrate → draw → QA/compose. The hard part is not the drawing; it is not lying about what the footage shows. One stage is a gate.

Requires: processing-video (ffmpeg, present), invoking-gemini (image + video models), proxy.env (CF gateway creds — auto-read by the gemini client).

Stage 0 — Probe & extract frames

ffprobe -v quiet -show_entries format=duration -of csv=p=0 in.mov
mkdir -p frames
ffmpeg -v error -i in.mov -vf "fps=1,scale=640:-1" frames/f_%03d.png   # 1/sec, downscaled

Keep full-resolution stills too — you will feed them to the image model as reference. For a subject hidden in clutter, pull a few full-res frames at specific timestamps: ffmpeg -v error -ss 11 -i in.mov -frames:v 1 hr.png.
