Video Asset Pipeline

Read:

• creative-production/pipelines/video-assets.md
• creative-production/standards/asset-budgets.md
• creative-production/standards/provenance.md
• the completed hero or cinematic-scene brief

Required outputs

Unless the page proves otherwise:

• clean master outside the public repo
• desktop MP4
• mobile MP4
• poster
• reduced-motion still
• optional WebM after measured benefit
• manifest

Edit

• make the focal point deliberate
• grade against the real page copy
• remove unnecessary duration
• build an actual loop when looping
• remove audio unless user-controlled
• create mobile composition, not an accidental crop
• composite VFX before the browser when live blending adds no value

Encode

Use FFmpeg commands from the pipeline guide. For scroll scrubbing, compare a short-GOP and all-intra export in the target browser.

Integrate

• explicit dimensions or aspect ratio
• muted playsinline for ambient autoplay
• meaningful poster
• preload only what the first scene needs
• warm later video near use
• pause offscreen
• no essential information only in motion
• range-request verification for scrub media

Verify

Run:

npm run assets
npm run audit -- path/to/page
npm run smoke

Inspect desktop, mobile, reduced motion, slow loading, reverse scroll, and playback failure.

Do not downgrade resolution to hide a seeking problem. Fix the encoding and loading strategy.
