All four teacher presenter clips, each generated from the locked reference portrait with lip-synced dialogue in the locked 'sunny' voice. Review identity continuity clip-over-clip before assembly.
Identity anchor

Shot 1 — Hook
8s clip / ~6.5s line"I've been teaching for years, and one thing I've learned is that every child experiences the school year a little differently."
Baked lip-sync dialogue — Continuity test clip from Gate 2 — identity anchor reference for all other presenter shots.
Shot 3 — Parents' keepsake
5s clip / ~4.3s line"And as a teacher, I know how much parents would love to hold onto those moments."
Baked lip-sync dialogue — Reflective register, acknowledging nod. No music baked in — Raindrops bed is mixed at export.
Shot 5 — Product intro
4s clip / ~3.3s line"That's why I love the idea behind ClassBooks by StoriVault."
Baked lip-sync dialogue — REGENERATED (attempt 3, 2026-10-20): attempt 2's phonetic slice ('Store-ee Vault') produced the wrong 'Stori-vault' pronunciation. Rebuilt from a plain-spelled 'Story Vault' voice slice; transcript QC passed (exact match). Warm enthusiasm, open hand gesture.
Shot 8 — Closing sentiment
4s clip / ~3.3s line"It's something they can enjoy today and treasure as they grow."
Baked lip-sync dialogue — Soft heartfelt close, gentle final smile.
