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.
npx skills add 0x0funky/agent-sprite-forge --skill video2dsprite --agent codex
Same command for any agent — swap --agent for claude-code, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Video2dsprite (Grok Build only) Convert a **base 2D character image** into **dense animation sprites** using Grok Build's native video tools. ```text base still → image_to_video (in-place motion) → extract frames → chroma key → sample/normalize → strip / grid / GIF ``` ## Platform gate (read first) | Runtime | Supported? | | --- | --- | | **Grok Build** (xAI) | **Yes** — requires `image_gen` / `image_edit` + `image_to_video` (or `reference_to_video`) | | Codex / Claude / other agents | **No** — they lack Grok video tools. Tell the user this skill is Grok Build only and offer `$generate2dsprite` instead | If `image_to_video` is missing from the tool list, **stop** and explain. Do not fake motion with code-drawn frames. This skill is an **optional denser-motion path**. It does **not** replace `$generate2dsprite`: | Use `$generate2dsprite` when… | Use `$video2dsprite` when… | | --- | --- | | Crisp pixel sheets, fixed grids, identity-critical heroes | User wants denser intermediate poses / smoother feeling loops | | Attack/cast body sheets, prop packs, engine atlases | Experimenting with video-sourced run/walk/idle motion | | Production default for most game sprites | User explicitly

What does the video2dsprite skill do?
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.
How do I install it?
Run `npx skills add 0x0funky/agent-sprite-forge --skill video2dsprite --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From 0x0funky/agent-sprite-forge, a repository with 3,616 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
