First frame, last frame, and what each one controls
The first frame locks composition, subject, and lighting. The last frame is optional and defines where the shot lands — ideal for transitions, transformations, and loops.
- Single still: the whole clip grows from one image. Best for portraits, product shots, and scenes where you want subtle, believable movement.
- First + last frame: the model bridges two images. Use it for before/after reveals, day-to-night transitions, and match cuts.
- No last frame: the model extrapolates the motion freely — more creative freedom, less destination control.
