The exact prompt
as run, 1,408 characters. Every result for this prompt
[Task] Create a 60-second motion-graphic explainer video on the history of the printing press, from its origins to the present day. [Roles] - Higgsfield: creates every image in the video (still images only). - You: create all motion graphics and animation. [Style] Newspaper cutouts with mixed-media collage, highly polished: layered paper cutouts, torn edges, halftone textures, soft shadows, and bold editorial typography. [Rules] - Keep every fact and date accurate. - No text inside the Higgsfield images. Add all text yourself as animated typography. - Keep the look consistent across every scene. - End on the opening frame so the video loops. Never end on a hard cut. [Harness notes] Images come from the image-generation tool available to you (still images only). Render the final video to out.mp4 (1920x1080, 60 s). Write everything into the working directory. Remotion 4.0.527 is already installed for you in the current directory: node_modules is pre-installed and read-only, so do not run npm install or create-video, and a remotion.config.ts here already points rendering at the local Chromium. Render the final video yourself to out.mp4 in the current directory (for example npx remotion render <entry file> <composition id> out.mp4). You may render stills or frames and inspect your own output (headless chromium is available at /usr/bin/chromium) and iterate on your own before finishing.

Run notes
- frozen prompt (written): prompts/video_printing_press_collage.md verbatim + the engine's standard Remotion harness suffix (same wording as remotion_* tests)
- plain wave-1-equivalent cc_config copy (settings.json + .claude.json; no ECC files)
- W2: the framework's pinned node_modules is bound read-only at work/node_modules (the prompt's 'pre-installed and read-only'); Node 22.23.3 and work/node_modules/.bin first on PATH; headless Chromium /usr/bin/chromium
- Mode: interactive TUI in tmux (160x48), inside bubblewrap sandbox
- Context setting: 1M ([1m] model name)
- Isolation audit: contamination
