# 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 ```bash 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`. --- ## Stage 1 — GROUND THE STORYLINE (the gate) **Never narrate a scene whose subjects and action you have not confirmed from the footage.** Diagnosed failure 2026-07-18: built an entire "indoor cyclist in a garage" storyline off thumbnail-sized frames of a video that was actually a leashed dog watching a deer — no bicycle in any frame, the leash visible in four. Then fed the fiction to the image model, which dutifully drew it. A wrong storyline launders a hallucination into finished art. The absence of a clear read is not license to invent a vivid one. Two ways to ground. **Prefer Mode B** — it is the more reliable and reads the whole clip, not sampled stil...
