video2dsprite
Grok Build ONLY. Turn a 2D character still into smooth animation sprites via image_gen/image_edit base → image_to_video (6s/10s run-in-place) → ffmpeg frames → magenta chroma-key → dense sampled sprites (strip/grid/GIF). Use when the user wants video-to-sprite, motion capture from generated video, smoother run/walk cycles from dense frames, or runs /video2dsprite. Do NOT use on Codex/Claude — only Grok Build has image_to_video. Prefer generate2dsprite for crisp pixel sheets without video.

Video to 2D Animation
An approved still sets identity and geometry, a video model supplies motion, and deterministic tools prepare it for the engine. Video is not promised to be smaller, seamless or cheaper than sheets.
Use when
- Animating a character or creature: every action comes from one approved master still, one clip per action.
- Fluid motion from an accepted master: idle breathing, walks, runs, attacks, casts, hair, capes, creatures.
- A supplied clip must become transparent, registered, looped frames and engine video.
Do not use when
- FX, icon or prop sheets: generate2dsprite.
- Water, fire or mist inside a still scene plate: generate2dmap. Only an API or CLI call: generate2dmedia.
- Code-drawn animation the user asked for: codeart2d.
Capability check (once per session)
Run python "<skill-dir>/../generate2dmedia/scripts/forge_doctor.py" --host-tools <tools> --save <output>/doctor.json, where <tools> lists the media tools in your own tool list (image_gen, image_edit, image_to_video) or none. Its ROUTES block shows which API keys are configured (yes or no), the local readiness and the resolved order. If encoding.stdout fails, set PYTHONUTF8=1. python "<skill-dir>/scripts/video2dsprite.py" doctor checks ffmpeg (5.1+, VP9 alpha round trip).
Art source
The master still comes from generate2dsprite (image generation, approved by the user) or from the user. Motion is image-to-video, one clip per action from that master; record the route as art_source and name it in your reply:
