fal-motion

fal-motion is a skill for Claude Code from mertagralii/fal.ai-butler. It costs 85 tokens per session (553 once invoked), scanned A, original, MIT.

A motion-planning layer that turns still keyframes into video clips and links scenes together visually. It prepares movement instructions, frame links, and timing details for a video model.

In plain words
What is it for?
Use it to plan image-to-video prompts, choose first and last frames, chain keyframes across scenes, keep a character consistent, and split scenes into clips that fit the model’s limits.
Why use it?
It prevents characters and scenes from changing unpredictably between shots. It also catches clips that exceed a model’s duration limit instead of silently shortening them.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

fal-motion scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

fal-motion — hareket yönetmenliği

Durağan anahtar kareyi harekete geçiren katman. İki işi var: her sahneyi videoya çevirmek ve sahneleri birbirine görsel olarak zincirlemek — karakterin altı sahne boyunca aynı kalmasını fiilen sağlayan mekanizma burada kurulur.

Referanslar

  • references/motion-prompting.md — video modeline hareket tarif etme dili
  • references/keyframe-chaining.md — karakter sayfası, zincir, seed sabitleme
  • references/duration-budget.md — klip süre sınırları, sahne bölme

Girdin ve çıktın

Girdi: görsel reçeteler (fal-dop'tan) + sahne süreleri (fal-director'dan) Çıktı: sahne başına hareket reçetesi + zincirleme grafiği (hangi düğüm hangisini besliyor)

  • süre/fps/çözünürlük/seed parametreleri

Zincirleme grafiği fal-compiler'ın depends ilişkilerini kuracağı şeydir — düğüm bazında net yaz.

Süre gerçekliği

Video modelleri klip başına sınırlı süre üretir ve bu sınır modelden modele değişir. Şemadan oku, varsayma. Sahne süresi sınırı aşıyorsa böl ve zincirle; mümkün değilse fal-director'a bildir ve kullanıcıya söylenmesini sağla. Sessizce kısaltma.

fal-audio ile geri besleme

fal-audio "bu cümle 7 saniye sürer ama sahne 4 saniye" derse bir kez geri gelirsin. Öncelik metni kısaltmaktır (fal-audio yapar); sahneyi uzatmak ikinci tercihtir çünkü toplam süre hedefi kullanıcıdan gelir. İkinci tur yok — ikinci uyuşmazlıkta kullanıcıya bildirilir.

Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
