Horizontal Diagnostic Talk Video

Goal

Create a 16:9 horizontal video that opens with a full-screen diagnostic panel, not the speaker. The viewer should understand the topic, audience, and judgment framework within 3 seconds — before the speaker ever appears.

This skill is for videos that answer "what should I look at first?" rather than "how do I do this?"

Required Inputs

• Source talking-head video (16:9)
• Original script, if available
• Diagnostic framework: categories, criteria, or judgment axes
• Title and CTA
• Output target: 1920x1080, 30fps, H.264/AAC

Workflow

1. Inspect source with ffprobe. Extract frames to check face position.
2. Transcode to 1920x1080 H.264/AAC if needed.
3. Transcribe and correct captions. Pay extra attention to judgment statements and CTA.
4. Design the opening diagnostic panel: topic, audience, criteria, visual framework.
5. Segment the rest into chapters: diagnostic opening → speaker explanation → flow boards → standards → CTA.
6. Create props or edit timeline. The diagnostic panel should occupy 5-9 seconds at the start.
7. Render stills for the diagnostic panel and key chapters.
8. Render full video and generate contact sheet.

Layout Rules

Diagnostic Opening (5-9s)

• No speaker in first frame. Full-screen information panel.
• Topic title: large, centered, immediately readable.
• Audience labels: 2-4 tags showing who this is for.
• Framework axes: business categories, size ranges, readiness levels.
• Accent color: bold, distinguishing from later chapters.
• Transition into speaker: smooth, not abrupt.

Speaker Chapters

• Speaker becomes primary visual after diagnostic opening.
• Same rules as horizontal-content-talk-video: face safe, cards on sides, subtitles bottom.
• Use PIP when showing methodology boards.
• Return to full speaker for identity statements and CTA.

Flow Board Chapters

• Full-screen animated boards with PIP speaker anchor.
• Components reveal by phrase, not all at once.
• Board background: blurred source video for continuity.

Scene Pattern

1. diagnostic: Full-screen panel. No speaker. Topic + audience + framework.
2. intro: Speaker enters. Restate the promise from the panel.
3. mistakes: Full board + PIP. What gets wrong.
4. method: Full board + PIP. Process or framework.
5. standards: Full speaker. Identity or judgment summary.
6. cta: Board or speaker. Clear action.

Animation Rules

• Diagnostic panel: elements fade in sequentially within the first 3 seconds.
• Panel-to-speaker transition: under 20 frames.
• Card reveal: 8-10 frames.
• Component lead: 0.12-0.18s.
• Caption lead: 0.05s.
• Split any static visual over 14 seconds.

Caption Rules

• Same as horizontal-content-talk-video.
• Additional check: diagnostic panel text must match the first spoken sentence.
• The spoken "这条视频给谁看" must align with the audience tags on screen.

Quality Gates

Fail if any of:

• The first 3 seconds do not reveal topic and audience
• Speaker appears before the diagnostic message is clear
• Face blocked at any point
• Captions out of sync
• Board content unreadable
• Template debug words visible
• CTA does not match voice

Validation Commands

ffprobe -v error -show_entries format=duration -show_streams -of json "output.mp4"
ffmpeg -y -i "output.mp4" -vf "fps=1/5,scale=480:-1,tile=5x3" -frames:v 1 "contact.jpg"
ffmpeg -y -ss 0 -i "output.mp4" -t 5 -vf "fps=2,scale=480:-1,tile=5x2" -frames:v 1 "opening-check.jpg"
