# Shoot the performance, generate the rest

Recipes / Preset / Production. Checked 2026-10-13.

Real acting and timing, with the person, room or costume replaced by the model.

- Use when: Ads where the budget goes to a performer, not to a set.
- Phrase: film the performance in a cheap plain room, then replace the person, the costume or the setting with Seedance 2.5 video edit, keeping the mouth and the timing

## Watch out

- When the face and lipsync must stay exactly real, no generative edit works: they re-render the person. Use a matte and composite instead. (measured; House rule)

```
Give me a production plan: the shots or scenes in order, what each one needs, and the edit settings, for a short video about [your product], for [your audience]. The technique is shoot the performance, generate the rest: real acting and timing, with the person, room or costume replaced by the model. How it works: film the performance in a cheap plain room, then replace the person, the costume or the setting with Seedance 2.5 video edit, keeping the mouth and the timing. It is right for: ads where the budget goes to a performer, not to a set. When the face and lipsync must stay exactly real, no generative edit works: they re-render the person. Be concrete: numbers, seconds and settings, no theory. Ask me one question first if something you need is missing.
