First and last frame
First-frame, last-frame, and smart multi-frame video generation
Understand when to use first-frame, last-frame, and smart multi-frame controls for smoother transitions and clearer scene direction.
First-frame and last-frame generation helps a model understand where a clip begins and where it should end. Smart multi-frame workflows add more reference frames when a single image cannot describe the full motion.
Quick decision
Best for
- Transitions, product reveals, storyboard shots, before-and-after scenes, and clips with a controlled landing frame.
- Video tasks where the start or end state matters more than open-ended motion.
Not ideal for
- Simple motion drafts that do not need a fixed opening or ending composition.
- Models or routes that do not support first-frame, last-frame, or multi-frame inputs.
Choose this when
- You already know the opening frame, ending frame, or key visual states the generated video should follow.
First frame
Use a first frame when the opening composition must match a product shot, character pose, storyboard panel, or brand-approved image.
Last frame
Use a last frame when the clip needs to land on a specific ending: a product reveal, final pose, transition state, package close-up, or campaign key visual.
Smart multi-frame
Use smart multi-frame when a clip needs more visual guidance than a start and end image. This is useful for action direction, scene continuity, and complex camera movement.
Quick answers
What is first-frame video generation?+
First-frame generation uses an uploaded image as the opening frame so the video starts from a controlled composition.
What is last-frame video generation?+
Last-frame generation uses an uploaded image as the target ending so the clip moves toward a specific final composition.
When should I use smart multi-frame?+
Use smart multi-frame when the motion is too complex for one reference image, such as a transition, action sequence, or staged product reveal.
