Real API image-to-video results
Source images and generated videos are shown separately. Copy a prompt to reproduce the motion language or adapt it to your own image.
The source defines the visual opening while the request can add motion, camera, ambience, and sound.
Prompt used for this verified run
Smooth cinematic image-to-video motion with coherent subject movement, gentle camera travel, realistic ambience and synchronized sound.
Choose by starting material, reference method, resolution, and shot-control requirements.
Fast image animation
Animate still images with efficient camera and subject motion.
Veo 3.1 Fast Image to Video turns a source image into a continuous video shot while preserving recognizable subject details.
The Playground and API use model ID veo-3.1-fast/image-to-video. Keep image guidance and motion instructions in the same request.
These specifications reflect the current HiAPI Veo 3.1 Fast Image to Video request contract. Endpoint frames and multimodal references are separate input modes and should not be mixed.
Starting price is 500 Credits / second.
Start with a clear input image and a short clip, then increase duration after subject and motion are stable.
This is a minimal asynchronous first/last-frame request. Use the API docs for callbacks, task retrieval, reference limits, and error handling.

}'Yes. veo-3.1-fast/image-to-video is an image-to-video route. The image establishes the subject and opening composition; the prompt directs motion, camera, and environmental change.
The current HiAPI contract supports 4s / 6s / 8s at 720p or 1080p or 4k. Check the page controls and API docs for the current options.
Billing follows output duration and the selected tier. The page follows the global display unit, while the successful task record contains the final charge.
Use a clear, unobstructed source with a complete composition. Describe the main action and camera first, then name the appearance, material, and background relationships that must remain stable. Validate a short clip first.
The first frame defines subject, composition, and shape. Add a matching last frame only when the ending state must be fixed, leaving room for the intended motion.
Write the middle process in time order, state whether the camera is locked, preserve stable details, and place sound cues next to their matching events.
Start at 4 seconds to inspect endpoint continuity and subject stability, then increase duration or create the production task with veo-3.1-fast/image-to-video.
