>- Produce video with Moonvalley's Marey model family (Marey Realism v1.5) — a filmmaker-oriented, 1080p/24fps generative video model marketed as trained exclusively on licensed data. Use this skill when a task asks for Marey or Moonvalley specifically, when a brief demands brand-safe / legally reviewed AI video for commercial or studio work, or when the request needs Marey's director-style controls (camera trajectory, motion transfer, pose transfer, keyframing, reference conditioning). It covers what "commercially safe" really means versus the actual terms of service, access routes (Moonvalley web / Voyager, the fal API, ComfyUI), pricing, capability limits, prompt and reference strategy, where Marey fits production versus where other models win, iteration, and quality review. Do not use it for audio generation, for photoreal talking-head dialogue, or as a generic "best video model" default.

Marey is Moonvalley's generative video model, aimed at professional filmmakers,
studios, and brand teams that need AI video they can put through legal review.
Its differentiator is not raw fidelity — it is provenance: Moonvalley
markets Marey as trained exclusively on owned or licensed footage, and pairs it
with a set of director-style controls. This skill helps an agent decide when
Marey is the right tool, use it correctly, and — critically — represent its
legal posture accurately rather than repeating marketing.
Verification date for all volatile facts below: 2026-07-10. Re-check
version, pricing, endpoints, and the terms of service before relying on any
dated claim.
Marey was built with the animation studio Asteria. Moonvalley raised an
additional $84M in July 2025 (investors incl. General Catalyst, CAA, Comcast
Ventures, CoreWeave, Khosla Ventures, Y Combinator), reportedly ~$154M total.
The company is active and funded — not shut down or pivoted. [businesswire,

It first entered public availability July 2025 after an earlier limited
release (March 2025). [techcrunch, fal]
that exposes Marey's fuller control set for studio workflows. [businesswire]
"cinematography-first" brand positioning.
Treat "v1.5" as volatile. Moonvalley has publicly promised further controls
(lighting, deeper object trajectories, character libraries); a newer point
release may exist by the time you read this.
These are documented on the fal model pages and Moonvalley/partner docs
(verified 2026-07-10). Distinguish them from marketing claims below.
| Property | Value | Note |
|---|---|---|
| Output resolution | Native 1080p (default 1920×1080) | Trained on native 1080p; other dimensions selectable |
| Frame rate | 24 fps | Cinema-standard cadence |
| Clip duration | 5s or 10s per generation (v1.5 on fal); shot-extension to lengthen | Original 2025 launch capped at ~5s; v1.5 adds 10s + extension |
| Audio | None | Marey is silent video only — no native dialogue, SFX, or music. Add audio in post |
| Training content | "Owned or fully licensed," native 1080p, no user-generated content (first-party claim) | See legal section |
Consequences an agent must plan around:
audio separately (ElevenLabs, a DAW, licensed music). If the brief's value is
in synced sound, Marey is not the model — Veo 3 generates audio natively.
in an NLE. Plan a shot list, not a single long generation.
natively deliver 4K.
This is the single most important thing to get right, because it is where an
agent most easily misleads a user.
Moonvalley markets Marey as **"the world's first commercially safe video model
... trained only on licensed, high-resolution footage. No scraped content. No
user submissions." Reporting indicates roughly 80%** of training footage
came from filmmakers/agencies who intentionally licensed B-roll, with archive
material secured through partnerships (e.g. Vimeo); the remainder from other
owned/licensed sources. This is a **first-party claim about training-data
provenance**, corroborated by press but not independently audited. Present it as
"Moonvalley states / claims," never as an established fact. [moonvalley, cined,
techcrunch]
The plausible legal benefit is at the input side: a model trained only on
cleared footage is far less exposed to the training-data copyright suits now
facing scraped-data competitors. For a risk-averse studio or brand, that reduces
one specific category of risk — the "was this model built on my/others' stolen
work" question — and that is a real, defensible reason to choose Marey.
Do not equate "trained on licensed data" with "you are indemnified." The actual
consumer Terms of Service (help.moonvalley.com, verified 2026-07-10) run the
other way:
"defend, indemnify, and hold harmless" Moonvalley from claims arising out of
the user's use of the service, their content, or infringement of others'
rights — including paying defense costs. [moonvalley ToS]
Moonvalley disclaims indirect/consequential/special damages. [moonvalley ToS]
provides indemnification for its data-collection contractors — not a
blanket output indemnity to end users. This is materially different from
Adobe Firefly, which offers enterprise customers indemnification for using
its video model. [techcrunch]
content-removal/data-deletion options, and it markets bespoke **enterprise /
studio agreements** (including custom fine-tunes on partners' IP). Any real
output indemnity for a specific customer would live in a negotiated enterprise
contract, not the public ToS. [techcrunch, deadline]
Agent rule: When a user cites "commercially safe" as a reason to skip legal
review, correct the framing. The honest position is: *Marey lowers
training-data provenance risk and is a strong candidate for brand-safe work, but
the standard terms shift indemnification onto the user and cap liability — so
studios must still run legal review, and any indemnity guarantee must be secured
in an enterprise agreement, in writing.* Never tell a user their Marey output is
"legally cleared" or "guaranteed" on the strength of marketing copy alone.

Budget implication: iteration is the real cost. At ~$1.50–$3.00 per attempt and
Marey's inconsistency (below), a single usable 5s shot may take several
generations. Estimate 3–8 attempts per keeper shot when quoting a budget.

middle ground, background (Marey is marketed as "3D-aware").
Heuristic: reach for these controls precisely because Marey's blind text-to-video
is inconsistent. Motion transfer and pose transfer replace fragile prompted
motion with a real reference, which is where Marey earns its place — previz,
restyling a plate, or matching a specific camera move.
Marey rewards long, structured, cinematographer's prompts far more than terse
ones. Moonvalley's own guidance recommends at least ~50 words and a
layered structure. A documented formula (Moonvalley help center):

> details] + [Lighting / technical specs]**

This is a first-party-claim-vs-independent-review split: Marey's licensing story
is genuinely differentiated, but a hands-on practitioner review (Curious Refuge,
2025) scored its output quality low (~3/10) versus peers, citing temporal
instability, collapsing hands/gestures, flicker on camera moves, and plastic
skin. Treat that as one disclosed-method practitioner report, not a benchmark —

| Symptom | Likely cause | Repair |

| Warped hands / collapsing gestures | Known weak spot in fine articulation | Avoid tight hand close-ups; use pose transfer with a clean reference; hide hands or keep them still |
| Flicker on camera movement | Motion instability | Use Camera Control from a single image instead of prompted motion; slow the move; shorten the clip |
| Plastic/stiff human performance | Photoreal-dialogue is not a strength | Reconsider model for talking heads; use stylized look; drive performance via pose/motion transfer |
| Weak prompt adherence | Terse or unstructured prompt | Rewrite to ≥50 words in the camera→scale→action→environment→lighting structure |
