Dark SaaS Magic Video

Role

Create new product videos in a dark, cinematic, UI-conjuring style. This is a style-generation skill, not a reference-alignment skill. Use it after rn-motion-director selects a style-level product or SaaS video route.

Canonical Showcase

• Human display name: 暗色 SaaS 魔术短片
• Example finished piece: 雪踏乌云暗色 SaaS 介绍短片
• File: assets/showcases/xuetawuyun-dark-saas-showcase-1080p.mp4
• Use this as a style reference for scale, pacing, scene vocabulary, and final polish. Do not copy its text unless the user asks for the same brand/account.

Boundaries

• Use this for style-level creation: "做成这个感觉", "类似 Presenton 这种风格", "暗色科技感 SaaS 产品短片", "AI 工具产品演示".
• Do not use this for pixel-level, frame-accurate, or timestamp-accurate remakes. Use rn-replica-qc first.
• Do not replace product-launch-video; use this when the requested visual language is specifically dark magic UI, not a generic product launch.
• Build with HyperFrames unless the user explicitly requests Remotion.

Required Reads

Before writing a composition, read:

1. references/style-language.md
2. references/scene-blueprints.md
3. references/timing-presets.md
4. references/asset-contract.md

Before final handoff, read references/qc-checklist.md.

Inputs

Collect or infer:

• product name and one-line promise
• target viewer and platform
• duration preset: sting, standard, or extended
• pain words or opening claim
• core workflow: prompt, generate, connect, model, export, share, automate
• available assets: logo, screenshots, UI cards, integration logos, export names
• output ratio and archive slug

If assets are missing, use abstract UI cards and text badges. State that the result is a style-level product video, not a product-accurate UI recording.

Hard Style Rules

1. Use a black spatial stage with fine grain/star particles and a weak bottom purple horizon glow.
2. Avoid persistent horizontal neon-line backgrounds; they flatten the style.
3. Use large white kinetic typography as story beats, not small labels.
4. Include at least one cyan-to-magenta gradient CTA that triggers a visible transformation.
5. Make hero objects large at their most visible frame: prompt card, CTA, UI board, badge ring, or export object must not feel like tiny distant props.
6. Use speed blur, smear, scale rush, or white velocity wipes for major transitions.
7. Include UI objects that feel summoned from darkness: cards, badges, folders, model chips, app windows, or export pills.
8. Never add unexplained full-screen solid color flashes.
9. Never claim pixel-level fidelity for this style workflow.

Workflow

1. Shape The Arc

Pick a duration preset from references/timing-presets.md. Map the product into 5-8 capability beats. Prefer a cause-and-effect chain: text promise -> prompt -> CTA click -> generated result -> integrations/models -> export -> final claim.

2. Select Blueprints

Use references/scene-blueprints.md to choose scene modules. Do not blindly use all modules; match the product's real capabilities.

3. Build With HyperFrames

Load the relevant HyperFrames skills:

• hyperframes for composition authoring
• hyperframes-cli for lint, validate, inspect, render
• hyperframes-animation for speed blur, type motion, rings, cursor clicks
• hyperframes-media only if audio, TTS, SFX, or captions are needed

Use deterministic motion. Build hero frames first, then animate into them.

4. QC

Use references/qc-checklist.md. If the user supplied a reference video and cares about alignment, also use rn-replica-qc.

Output

Deliver the final MP4 path, QC contact sheet path, confirmed specs, and a short note naming the duration preset and scene modules used.
