What it does

This skill helps an agent produce video using Moonvalley Marey Realism v1.5, a professional, licensed-data video model with director-style controls. It instructs when to choose Marey (brand-safe, legally reviewed needs, or when motion/pose transfer and camera trajectory are required) and outlines its output constraints (1080p 24fps, no audio, short clip lengths) and governance around training provenance and indemnity. It covers how Marey fits production compared to other models and provides a workflow for iteration, reference-driven control, and post-processing.

How it works

The skill outlines to use Marey through multiple access routes (Moonvalley web app/Voyager, fal API, ComfyUI) and to employ Marey’s controls: Camera Control, Motion Transfer, Pose Control/Transfer, Trajectory Control, Keyframing, Reference, Shot Extension, and Multi-layer Spatial Composition. It emphasizes constructing long, cinematographer-style prompts (minimum ~50 words) following a formula: [Camera movement] + [Scale / perspective] + [Core visual] + [Environmental details] + [Lighting / technical specs]. It prescribes aligning prompt strategy with a shot list of 5–10s clips, using motion/pose transfer with references when possible, and preferring i2v workflows to anchor composition. It also advises thorough quality checks for temporal consistency, hand/gesture accuracy, camera flicker, skin quality, and prompt adherence, and recommends post-processing steps (upscale, color, add audio off-platform).

When to use it

Use Marey when the client requires brand/studio-grade compliance with training-data provenance, the shot is single-subject or controlled, and there is a reference to drive motion or pose (or a previz need). Use it for projects needing director-style control through Marey’s ecosystem (Voyager, keyframing, shot extension) rather than for audio generation or multi-character, high-midelity talking-head work. If the brief needs native audio or complex multi-character choreography, other models may be preferred.

What it can touch

The skill lists the available tools and endpoints: Moonvalley web app / Voyager, fal API endpoints (t2v, i2v, motion-transfer, pose-transfer), and ComfyUI. Access parameters for fal API include prompt, image_url, negative_prompt, seed, dimensions, duration. Pricing details for per-generation and credits are provided for planning budgets.

Caveats

Key cautions include: Marey outputs silent video with no native audio; 1080p is the ceiling (no native 4K), and short 5s or 10s clips require assembly in an NLE. The training-data provenance is a first-party claim, not an independently audited guarantee, and user indemnification is required by Moonvalley ToS with liability capped at the greater of $500 or amounts paid. Enterprise terms may offer more robust indemnity, but any output indemnity would be contractually defined. The model can exhibit temporal instability, hand/gesture fidelity issues, and motion/artifact risks, particularly under motion-heavy prompts; iteration cost is non-trivial (roughly 3–8 attempts per keeper shot).
