What it does

Motion Design is an agent skill from GTKottman/mortiflix-oss. The craft of a motion design video, from the look to the final: style frames, layout, type, colour, timing, easing and transitions. Use for every style frame, animatic and build.

Its SKILL.md is about 830 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Media & Creative, covering Motion graphics. The repository describes itself as: A motion design studio on your own machine: Claude makes the video step by step, you approve every stage. Bring your own Claude Code or API key. The licence is AGPL-3.0.

When your agent uses it

  • Every style frame
  • Animatic and build

Example prompts

  • “/motion-design”

What it can do on your machine

Read from SKILL.md and the folder at commit aea9533. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Motion Design loads about 833 tokens when it runs. Until then it costs about 48 tokens; SKILL.md has 504 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~48
When it runs · the whole SKILL.md, loaded when a task matches
~833

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Motion design

A motion design video is a sequence of designed frames that move. Design the frames first; motion connects them.

The look (style frames)

  • A frame is a moment, not a mood board. Each style frame is a real shot from the script, with its real words, at full resolution. If it can't appear in the final video exactly as drawn, it isn't a style frame.
  • Pick the system before the pictures. Write design/LOOK.md first:
    • palette: 1 background, 1–2 neutrals, 1 accent (hex values). The accent marks the one thing to look at.
    • type: one family for headlines, one for body at most. Licensed (Google Fonts are a safe default). Sizes on a scale (e.g. 1.25×). Headlines ≥ 5% of frame height in 16:9, larger in 9:16.
    • grid: margins (title-safe 5%, action-safe 3.5%), columns, where text lives.
    • shape language: rounded or sharp, flat or dimensional, line weight, texture (grain, paper, none).
  • Three to five frames that cover the range: the opening, the densest information moment, a transition state, the ending card. If they don't look like one film side by side, the system isn't done.
  • Brand files from the brief win. Use their logo as given (never redraw it), their colours exactly.

Layout

  • One focal point per frame. Squint: the thing you want seen first must still stand out.
  • Align everything to the grid. Text left-aligned unless it's a single centred line.
  • Contrast for text ≥ 4.5:1. Never text on a busy area without a plate or a shadow.
  • Nothing touches the frame edge except full-bleed shapes.

Timing

  • Narration sets the clock (or the music's beat grid when there's no voice). Every beat starts on a word or a hit.
  • Read time: on-screen text stays at least words / 3 + 1 seconds after it finishes animating in.
  • Holds: let the key idea sit still for a beat. Constant motion is noise.
  • Pace changes are structure: a faster middle, a slower landing.

Motion

  • Easing: nothing moves linearly except mechanical things. Ease out on entrances (fast in, soft landing), ease in on exits. In Remotion, spring({ frame, fps, config: { damping: 200 } }) for calm, lower damping for bounce.
  • Stagger related elements by 2–4 frames; never animate a whole layout as one block.
  • Overlap actions: the next element starts before the last one fully settles.
  • Transitions carry meaning: a shape from one scene becomes the frame of the next (match cut), or the camera moves through the space. Use crossfades only when nothing better connects the two ideas.
  • Anticipation and follow-through for anything with weight.
  • Keep motion inside the safe areas; motion blur on fast moves (or don't move that fast).

Sound

  • Music sits about 18 dB under the voice while it speaks; it can come up in the gaps.
  • Sound design (whooshes, clicks, hits) on maybe one action in five: the important ones.
  • Mix to -14 LUFS integrated, true peak ≤ -1 dBTP (final-pass skill).

Before every submission

View every still you send. Run qc.mjs on every video and look at the sheet. Read every word on screen once more.

The craft of a motion design video, from the look to the final: style frames, layout, type, colour, timing, easing and transitions.

When should I use Motion Design?

Motion Design fits situations like: every style frame; animatic and build.

How do I install Motion Design in Claude Code?

Run `npx skills add GTKottman/mortiflix-oss --skill motion-design -a claude-code`. Or copy the skill folder (pipelines/_shared/skills/motion-design in GTKottman/mortiflix-oss) into .claude/skills/motion-design in your project. Claude Code loads it when a task matches its description.

How do I install Motion Design in Codex?

Run `npx skills add GTKottman/mortiflix-oss --skill motion-design -a codex`. Or copy the skill folder (pipelines/_shared/skills/motion-design in GTKottman/mortiflix-oss) into .agents/skills/motion-design in your project. Codex loads it when a task matches its description.

Can I use Motion Design in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add GTKottman/mortiflix-oss --skill motion-design -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/motion-design, .gemini/skills/motion-design, .github/skills/motion-design and .opencode/skills/motion-design in your project.

What does Motion Design need to run?

SKILL.md names no scripts, command-line tools or credentials: Motion Design is instructions for the agent only.

Does Motion Design access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Motion Design safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Motion Design use?

Motion Design is published under the AGPL-3.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Motion Design use?

About 833 tokens (SKILL.md is roughly 3.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
