Product Demo Integration

Product Demo Integration

Use this skill when product footage is part of the final video.

Intake

Before editing:

• Probe recording duration, resolution, frame rate, and audio.
• Identify whether the recording includes a canvas, browser frame, cursor, zooms, scrolls, or dead time.
• Identify required product moments and their timestamps.
• Identify narration phrases that must align with product states.
• Ask for approval before aggressive crop if important UI may be cut off.

Crop Decision

Default to preserving UI over removing background canvas.

Use crop only when:

• The important UI remains visible throughout zooms and scrolls.
• The crop does not cut off headings, labels, cursor context, or final state.
• A proof frame confirms the tightest zoom still works.

Use no-crop or light crop when:

• The recording zooms into different areas.
• The product moment moves around the canvas.
• The user already says cropped output cut off key text.

Read references/crop-and-zoom.md for a checklist.

Transition Into Product Footage

• Start from the previous scene final frame.
• Use camera swipe or push motion rather than a hard cut if continuity is requested.
• Land on the current first frame of the product recording.
• If the recording starts with dead time, trim it only if doing so does not break sync.
• If a product moment must align with narration, retime the segment before that moment rather than changing all later sync.

Transition Out

• Preserve the last meaningful product state long enough for the viewer to register it.
• Create a camera swipe to the next scene if requested.
• Avoid accidental blank frames at the end of screen recordings.
• Extract a proof frame at the transition boundary.

QA

• Check first product frame.
• Check every zoom peak.
• Check every required product state.
• Check transition in/out.
• Confirm captions do not cover product UI.

Output

Return:

• Source recording used.
• Crop/no-crop decision.
• Trim/retime segments.
• Render path.
• Proof frames for tightest crop and key product moments.

Product Moment Map

Create a moment map before editing:

• Recording timestamp.
• What is visible.
• Narration phrase.
• Desired global timestamp.
• Whether cursor matters.
• Whether scroll position matters.
• Whether captions overlap.
• Whether crop is safe.

Use this map to decide trims and retiming.

Crop Decision Matrix

Choose no crop when:

• The user accepts canvas/background.
• Zooms move across the screen.
• Main text is cut by a tight crop.
• The product state is more important than polish.

Choose light crop when:

• Canvas is distracting but UI stays centered.
• Captions need more room.
• Browser chrome or dead margin can be removed safely.

Choose dynamic crop only when:

• Each crop rectangle is mapped.
• The movement feels intentional.
• All key product states have proof frames.

Narration Sync

Sync product states to spoken phrases:

• Start transition before the phrase if the product must be visible on the phrase.
• Let final product frame hold after the phrase if comprehension matters.
• Slow pre-moment footage rather than speeding a product scroll unnaturally.
• Do not cut mid-word in narration to reach a product state.

Screen Recording Cleanup

Check:

• Cursor visibility.
• Browser UI.
• Notification popups.
• Dead time.
• Blank loading screens.
• Accidental desktop edges.
• Scroll speed.
• Zoom focus.

Only remove or hide these if it does not harm product clarity.

Caption Safety

If captions are burned in:

• Check bottom nav bars.
• Check product tables.
• Check modal buttons.
• Check timeline controls.
• Move caption margin or choose a different proof frame if needed.

User Approval Points

Ask before:

• Cropping out visible canvas.
• Removing cursor.
• Speeding footage dramatically.
• Blurring or masking product details.
• Replacing real footage with recreated UI.

Handoff Format

Report:

• Product clip used.
• Crop strategy.
• Trim points.
• Retime ratios.
• Key proof frames.
• Any UI that remains imperfect by design.
