B2B Video Studio

Approach
one world
per clip, prompts editable by scene

Task: build advertising video scenes of a product with an “AI director”: one world for the whole clip, with prompts editable scene by scene.

How it works

  1. 0101VLM analysis of the photo and the card text
  2. 0202A scene plan inside a single world
  3. 0303Seedance, multi-reference against hallucinated geometry
  4. 0404Independent regeneration of a single scene

Particulars and difficulties

The world resets between scenes

One world is held across the whole clip, so the scenes read as one shoot

The model invents the product’s geometry

Multi-reference is what keeps the product itself from drifting between scenes

A person has to stay in control

Scene prompts are editable rather than a re-roll of the whole clip

One bad scene

Any scene is regenerated on its own, without touching the rest

Results

1
world across the whole clip
4
stages from photo to video
1
scene regenerated at a time

An advertising scene rather than a demo render

The product keeps its geometry, and the clip holds together across scenes

An edit does not cost the whole clip

Regenerating one scene is cheaper than re-rolling everything
