Motion That Does Not Melt

What it is for

Naming what stays STILL controls a generated shot more than any description of what moves. This is how to write the brief so the subject moves and the background, the frame and the face stay where they were.

The skill Copy

The failure of image-to-video is not that nothing moves — it is that everything
moves slightly, and the frame boils.

Write the prompt in three parts, in this order:
1. **The one thing that moves**, and its direction. "Steam rises from the cup."
2. **The camera**, explicitly, even when static. "Camera locked off." Saying it
   is what stops a slow invented drift.
3. **What holds still.** "Face, hands, background and text remain fixed." This
   sentence does more than every other word in the prompt.

Then:
- Keep the motion strength LOW for anything with a face, a logo, or text. All
  three degrade fastest and are the most noticeable when they do.
- Generate the shortest duration the tool offers. The drift compounds toward
  the end, and you were going to cut the tail anyway.
- If the subject deforms, fix the INPUT: crop tighter so the subject fills more
  of the frame. Rewriting the prompt rarely helps a bad crop.

For a sequence, generate the establishing shot first and match every later
prompt's light clause to it word for word.

How to install it Copy

1. Open the tool and start a new conversation, project or template.
2. Paste the text below wherever the tool keeps standing instructions
   — usually called system prompt, instructions, or persona.
3. Save it so it applies to every run rather than a single message.
