openmontage-video-prompting

openmontage-video-prompting is a skill for Claude Code from MrJPTech/macro-pickle. It costs 132 tokens per session (2,072 once invoked), scanned A, original, MIT.

A guide for writing detailed prompts for AI video generators such as Seedance, Veo, Sora, Runway, and Kling. It describes the subject, actions, setting, positions, camera, and other details needed to control a generated video.

In plain words
What is it for?
Use it to create or refine storyboards, director briefs, scene packs, and other structured prompts for AI-generated videos.
Why use it?
It reduces vague prompts that produce the right subject but the wrong movement, camera position, or scene layout. It also helps adapt wording to different video-generation models.

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

openmontage-video-prompting 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.

How it starts

The opening of the file, as written. The whole thing — 154 lines — stays where its author put it; the contents beside it link to each section on GitHub.

OpenMontage Video-Gen Prompting

Distilled from OpenMontage's skills/creative/video-gen-prompting.md and its per-model guides (from the OpenMontage project). This is the control layer on top of macro-pickle's existing Director Brief. The Prompt Engine (buildVideoPrompt in scripts/lib/prompts/video.ts) renders the structure; this skill teaches you what to put in each slot so the model actually renders it.

Read this BEFORE hand-writing a video prompt or filling a VideoBrief. It does not replace /pickle-prompt — it makes the brief you feed it far more precise.

The one rule that matters most

VLM research (CMU/Harvard) shows generation models reliably render subject and scene but routinely fail on motion, spatial, and camera. So the highest-leverage habit is forcing every prompt to fill all five aspects:

[Subject]        type + 3–6 disambiguating visual attributes
[Subject Motion] actions in TEMPORAL order; subject↔object & subject↔subject interactions
[Scene]          overlays (listed separately!) + POV + setting + time-of-day + dynamics
[Spatial]        shot size + position-in-frame + depth (FG/MG/BG) + camera height — and how they CHANGE
[Camera]         speed → lens distortion → height → angle → focus/DoF → steadiness → movement

Shorter prompt = more creative freedom. Longer prompt = more control. Match length to the model (below). A prompt is self-contained only if a reader who never saw the shot could picture it from the text alone.

Per-model length sweet spots

Model Sweet spot Notes
Seedance 2.0 200–400 w (hero), 80–150 w (insert) macro-pickle's premium default; rewards long structured 5-aspect prompts, single-pass synced audio, multi-shot
Wan 2.2 200–400 w fine-tuned on long captions
Sora 2 / VEO 3.1 100–250 w plateaus past ~250
LTX-2 ≤ 80 w degrades past that — keep tight
Runway Gen-4 ≤ 60 w "focus on motion, not appearance"; one scene per clip
Kling 2.6 4-part supports ++emphasis++ syntax

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.
