AI-native Vertical B-roll — Keyframe Self Review v1

Date: 2026-08-30
Brief: 技術・経営思想の冒頭フック。1つの試行が複数経路へ分かれ、検証を経て1つの方向へ収束する。
Privacy: Public-safe generated plates. No first-party or third-party source assets used.

Shared decisions

• Audience action: stop scrolling, read the later Remotion title, then continue into the editorial short.
• Dominant emotion: curiosity followed by momentum and resolution.
• Visual protagonist: a single controlled path or physical sequence.
• Brand tension: disciplined physical craft versus abstract AI cliché.
• Motion affordance: sequential illumination, unfolding, rotation, parallax, and camera passage.
• Typography: none baked in; exact Japanese type is reserved for Remotion.

Candidate A — tech-paths-hook-v1.png

• Intended role: hook / branching possibility.
• Source assets: none; generated clean plate.
• Mode: new generation.
• Strongest feature: one cyan path creates immediate hierarchy and credible sequential-light motion.
• Remaining risk: the visual metaphor is not yet uniquely tied to Takumi/PENGIN and could be read as premium technology stock.

Score: 22/24

Blockers: none.
Decision: shortlist for independent review; do not send to video yet.

Candidate B — prototype-sequence-development-v1.png

• Intended role: development / iteration becoming tangible.
• Source assets: none; generated clean plate.
• Mode: new generation.
• Strongest feature: physical paper construction avoids generic hologram imagery and offers sequential unfolding.
• Remaining risk: no single protagonist is obvious at phone size; a star-like artifact in the lower-right corner reads as a possible watermark or decorative generator mark.

Score: 18/24

Blockers: possible watermark/decorative star; weak protagonist.
Decision: reject. If this concept is revisited, regenerate only the hierarchy/artifact defect rather than changing the whole style.

Candidate C — convergence-aperture-payoff-v1.png

• Intended role: payoff / many paths resolving into one.
• Source assets: none; generated clean plate.
• Mode: new generation.
• Strongest feature: the cobalt aperture and strong foreground ring create a credible camera move and loopable convergence action.
• Remaining risk: architectural sculpture is visually strong but still insufficiently specific to the customer story.

Score: 22/24

Blockers: none.
Decision: shortlist for independent review; do not send to video yet.

Current outcome

• 2/3 candidates pass the self-score threshold of 20/24.
• 1/3 is rejected with a blocker.
• No candidate is promoted to paid image-to-video until independent Claude review is returned and factual review claims are checked against the files.
• The visual system still needs stronger source specificity before being called a validated brand asset.
