Title Scene Takeover Motion Clip

Title Scene Takeover Motion Clip

A minimalist, typographic takeover clip that gives a recurring title a precise entrance, a quiet pause, and a memorable editorial finish.

Style: Gridline Takeover. A composed editorial title enters with measured confidence against a saturated ground, using space and timing as the main visual effects. Follow references/style-guide.md exactly.

Use this skill when

• Opening a recurring lesson or editorial series
• Introducing a chapter, topic, or episode before the main content
• Creating a polished transition between social publishing segments

Do not use

• Busy multi-message promos that need several calls to action
• Character-led, photographic, playful, or highly decorative motion treatments
• To reproduce another company's brand, logo, product UI or copyrighted characters.

Inputs

• The exact title or series name, with optional subtitle
• Target aspect treatment within the wide canvas and intended crop-safe area
• Preferred entrance energy: measured, brisk, or dramatic
• Optional episode number, lesson marker, or short metadata line

If something essential is missing, ask one short question before starting. Never invent facts, numbers, quotes or customer names; mark gaps as [needs source].

Workflow

1. Read references/motion-contract.md and references/style-guide.md. Their rules are fixed for this skill.
2. Fill references/scene-map.md from the brief (3-5 scenes, 6-12 s). Never invent product numbers, names or quotes; ask for anything required that is missing.
3. Copy references/composition.html to clip/composition.html. Keep the stage, the ambient layer, the progress line and the fit script.
4. Delete the example scenes you do not use, set each scene's text, data-start, data-duration and the absolute animation-delay values, and set <html data-duration> to the sum of scene durations.
5. Apply the style tokens in the :root block exactly as given in the style guide. Do not add colors or webfonts.
6. Open clip/composition.html in a browser to preview; it plays in real time. Reload to replay.
7. Render: node scripts/render.mjs clip/composition.html --out clip.mp4 --fps 30 (install once: npm i -D playwright-core && npx playwright install chromium; FFmpeg must be on PATH).
8. Run the validator below and fix every problem it reports.
9. Extract stills around each cut (ffmpeg -ss <t> -i clip.mp4 -frames:v 1 cut.png) and check that nothing is cropped, overlapping or frozen.
10. Run the validator and fix every problem it reports:

``bash node scripts/validate-video.mjs clip.mp4 --min-seconds 6 --max-seconds 12 ``

What makes this excellent

• Build the opening title as a left-anchored grid takeover: let the text cross into the frame rather than fading in at center.
• Use a single oversized title block with a controlled horizontal reveal and keep its line breaks deliberate at the wide canvas size.
• Carry one small metadata line through the composition so the clip can identify an episode, lesson, or chapter without adding clutter.
• Let the yellow accent appear once as an underline, index mark, or narrow moving bar; do not distribute accent color across every scene.
• Use a brief hold after the title settles, then exit through a clean crop or rule wipe that can loop into the next piece.
• Keep every important word inside a generous central safe area so social-platform crops do not remove the title.

Output contract

• clip.mp4: H.264, 30 fps, 1280x720, 6-12 seconds.
• clip/composition.html: the editable single-file composition that produced it (re-render any time with scripts/render.mjs).
• A hand-off note: the filled scene map, total duration, anything left as a placeholder, and the validator output.
• Render a wide MP4 between 6 and 12 seconds with four focused scenes and no external image dependencies.
• Keep the HTML/CSS source editable with title, subtitle, metadata, colors, and timing exposed as simple values.
• Use deterministic local rendering so the same inputs produce the same title treatment across a content series.

Reference demo and agent run

The preview is a reference render of the bundled composition with sample copy. In a real run the agent rewrites the scenes from the user's brief and assets, re-times the composition and renders a fresh MP4 that meets the output contract above.

Failure rules

• Never hand over a render that fails the validator.
• If the user's screenshots are low resolution, rebuild the surface in HTML instead of upscaling them.
• Music and footage must be supplied and licensed by the user; never download assets.
