How to Create Prompts for Seedance 2.5
A practical guide to creating precise prompts for editing real video — from changing the environment or outfit to modifying other visual elements — while preserving the original person, performance and camera.
The workflow below is free to read. The prompt engine — the file you upload to ChatGPT or Claude — is a paid download.
How to Use My Instruction
Use this workflow whenever you want to transform specific elements of an existing video without changing everything else.
You can use the instruction for environment changes, outfit changes, or other specific visual edits. The key idea is to clearly define what should change and what must stay unchanged in the original video.
How do you write a Seedance 2.5 prompt so the edit works as intended?
Go to ChatGPT or Claude
Upload the prompt engine together with two photos, in this order: first a screenshot of the original video frame, before any change; second the visual reference you want the edit to follow.
Then send this request:
Replace the text inside the brackets with a short description of your own reference.
You get back the finished Seedance 2.5 prompt.
When you need a visual reference, you can prepare it in ChatGPT Image first. For example, take a screenshot from your original video and describe the environment, outfit, lighting or other visual changes you want to create.
Go to Seedance 2.5
Upload your original video + the reference image or images.
Paste the prompt you generated in ChatGPT and generate the edited video.
You can change the environment while keeping yourself, your performance and the original camera setup intact.
