The hardest problem in AI video is keeping the same person or product looking the same in every shot. Wavemaker solves it with identity plates (minted subject stills, plus acquired reference photos when the entity is known) that run automatically on every generation.
How it works
- Detection. Recurring characters, products, and named entities are listed at planning time.
- A plate is minted or a photo is acquired. Uploads are ground truth. Known people/franchises may be searched and vision-verified (solo identity — collages are rejected). Invented lifestyle cast can mint from description.
- The run parks if a required reference is missing — it does not ship a lookalike and hope.
- Injection everywhere. Plates ride into every scene that features the subject (stills and motion).
- Verification. QC compares identity and wardrobe; drift fails the gate instead of soft-shipping.
What’s kept consistent
- Faces & bodies — the same person, every scene. For real people (your upload or a public figure), the face is locked while wardrobe follows the script — so the character can change outfits when the story calls for it, but never accidentally.
- Wardrobe — a recurring character keeps one canonical outfit across scenes unless the script deliberately changes it.
- Products — shape, materials, colors, and label text. Brand text on a product is transcribed from your real photo and spelled letter-perfectly in generated scenes.
- Logos — never re-rendered; your acquired logo file is composited with exact pixels.
Getting the best identity lock
- Upload a real photo. Your uploads are trusted as ground truth — a real photo beats any synthesized reference.
- One clean, front-facing, well-lit photo of a person; a straight-on, uncluttered photo of a product.
- Name your subjects. “Maya, the barista” is trackable across the script; “a woman” in five scenes may be five castings.
- Describe the look you want once (“tall, red hair, 30s”) — it binds the casting everywhere.
Brand kits
Your organization can save a brand kit — logo, colors, brand voice — that layers onto URL research: generations start from your locked identity, site research fills the gaps, and the kit wins on conflict. Engage stamps the kit when one is on the org.
Subjects persist across edits
Subject plates are saved with the session. When you come back and iterate or add a scene of the same character, it’s the same plate — same face, same wardrobe lock, same voice — unless you replace the reference.
