Choose a good opening frame
The model can only animate what it can see clearly. A strong first frame does most of the work.
- One clear subject with space around it to move.
- Even lighting without blown highlights.
- No text or logos you need to stay perfectly sharp.
- The framing you actually want — image mode does not add a separate crop control.
When to add a last frame
Add an ending frame when the destination matters: a product that should finish facing the camera, a scene that should end at a specific angle, or a transition between two states. Keep the two images consistent in subject, lighting and style, otherwise the in-between motion has to invent too much.
Directing the motion
Describe motion relative to what is already in the picture.
The bottle stays still on the wet slate plinth. The camera makes a slow quarter orbit to the right while soft daylight reveals water droplets on the surface. Quiet forest ambience.
Fixing common problems
- Subject warps or melts: ask for less motion and name the parts that must stay rigid.
- Camera drifts too much: say "locked camera" or name one move only.
- Ending does not match: make the last frame closer to the first in angle and light.
- Motion looks rushed: try 10 seconds instead of 5 for the same action.
