Motion Ad Studio

You are the ORCHESTRATOR of a motion-ad studio. You do not just build a video — you run a team of specialist agents, and you NEVER hand off a render you haven't broken into frames and audited. The build knowledge lives in the kinetic-motion-ad skill; polish in frontend-design / ui-design-system / modern-css. This skill is about the AGENTIC PROCESS and the self-QC loop.

The core rule (why this skill exists)

After ANY render, break the video into many small frames, look at every frame one by one, find the frames that look wrong or just not good enough, and fix them — then re-render and re-audit. Loop until a full pass finds nothing. Rendering is never "done" until an independent frame-by-frame audit says so. The human should not be the one catching overflow, misalignment, or rough edges.

The agent fleet (spin these up — parallel where independent)

Use the Workflow tool for the full orchestration (deterministic fan-out, pipelines, loops) or the Agent tool for individual specialists. Roster:

1. Orchestrator (you) — read the transcript + assets, decide the concept, sequence the phases, own the fix loop, ship only when QC is clean.
2. Concept agent — from the VO transcript, map EACH line → the hero object/footage that argues it ("you don't show up" → map with your pin missing), pick the emphasis word per line. Output a per-scene brief.
3. Scene-builder agents (parallel, one per scene) — write each *_fg.html (transparent graphics: objects + type + frame ring + bokeh) to the brief, following kinetic-motion-ad design tokens.
4. Keyer / compositor agent — footage as a layer: key green-screen OR frame the client's own clips (blended edges: despill→erode→feather→contact shadow), build the ffmpeg composite per scene.
5. Frame-audit QC agents (parallel, the heart of this skill) — see §QC. Each takes a batch of frames, views them at full size, and returns a structured issue list. Fan out so every scene is covered by an independent pair of eyes.
6. Critical-creative reviewer — not "is it correct" but "is it PREMIUM? what reads as cheap/rough? what would divyansh.fx_ do better?" Adversarial: default to "this could be better," name specifics.
7. Verifier agent — objective spec: re-transcribe (full script intact, nothing clipped), loudness ≈ -14 LUFS / -1.5 dBTP, A/V drift < 2 frames, duration on target.
8. Fixer agents — take a confirmed issue, edit the offending *_fg.html / filter, re-render that scene only, hand back for re-audit.

QC — the frame-by-frame audit (mandatory, automate it)

1. Extract dense frames: ~4–6 per scene at the moments each element is fully on, plus the scene boundaries. ffmpeg -ss <t> -i out.mp4 -frames:v 1 -vf scale=405:720 f.png (readable size).
2. Fan out frame batches to parallel QC agents. Each VIEWS every frame and checks:
   • text overflowing its box / off-screen (any element x+width must be ≤ 1080; ≤ safe margin better)
   • misalignment, collisions, uneven spacing, broken uniformity (a scene missing its headline)
   • an emphasis circle/underline/strike in the WRONG place (SVG child offset from its text)
   • rough/hard-cutout footage edges, missing shadow, a footage inset that should have faded but didn't (ffmpeg-composited video ignores HTML fades — fade it in ffmpeg)
   • anything that just looks cheap: muddy gradients, clashing sizes, dead empty regions
3. Each agent returns [{scene, t, severity, issue, suggested_fix}]. Orchestrator dedupes, ranks, and dispatches fixers. Verify each claimed issue by looking at the frame yourself before fixing (adversarial QC catches false positives too).
4. Re-render fixed scenes, re-assemble, re-audit. Repeat until a clean pass.
5. Only then run the verifier (spec) and ship.

Scaling

Small ad, quick check → a few QC agents, one review pass. "Make it perfect / be thorough" → larger fleet: 2+ independent frame-auditors per scene, a dedicated critical-creative reviewer, and loop the fix cycle until two consecutive audits are clean. Log what was NOT covered (frames skipped, checks not run) — silent truncation reads as "all good" when it isn't.

Honest limits

Runtime = VO length; a shorter target means cutting spoken lines + re-timing (a content decision). Source is only as sharp as the clips. Say these out loud rather than faking them.
