Image-to-Video with Seedance 2 Fast
Animate a still image into a cinematic clip with Seedance 2 Fast by ByteDance — the quick, lower-cost Seedance 2 tier. Start from a first-frame image, optionally set a last frame to control where the motion lands, and generate 4 to 15 seconds at 480p or 720p with synchronized audio included.
What makes Seedance 2 Fast Image-to-Video different
First frame in, motion out
Upload one image and Seedance 2 Fast animates it into a clip of 4 to 15 seconds. The prompt is optional but recommended — describe the motion, camera move, and mood rather than the image itself, and the model animates what it sees. Aspect ratio defaults to Auto, which simply matches your image's frame.
Last-frame control for directed motion
Add an optional last-frame image and the video transitions from your first frame to your second — a genuine keyframe workflow. It's how you get a product to rotate to a specific angle, a character to end in a specific pose, or a scene to resolve exactly where the next shot picks up.
Audio included in the per-second price
Fast generates synchronized voice, sound effects, and background music with the picture, and the rate is identical with audio on or off — about $0.09 per second at 480p and $0.20 at 720p. Sound-on animated clips cost the same as silent ones.
Cheap enough to test every image
At about $0.45 for a 5-second 480p clip, Fast is the tier for checking whether an image animates well before committing to a full-quality render. On a Scenetra board, wire an image-generation node straight into a Seedance 2 Fast node, iterate at 480p, then promote the winner to the full Seedance 2 for a 1080p final.

View model →Frequently asked questions
What is Seedance 2 Fast Image to Video?+
It's the image-animation mode of ByteDance's Seedance 2 Fast — the quick, lower-cost Seedance 2 tier. Upload a first-frame image, optionally describe the motion in a prompt, and it generates a 4-15 second clip at 480p or 720p with synchronized audio included. On Scenetra it runs as a node in the visual workflow editor.
How does last-frame control work?+
Alongside the required first-frame image you can upload an optional last-frame image, and the generated video transitions from one to the other. It gives you both ends of the motion — useful for directed camera moves, product turns, and shots that need to end in a specific composition.
How much does Seedance 2 Fast Image to Video cost?+
About $0.09 per second at 480p and $0.20 per second at 720p, audio included — the same rates as the other Fast modes. A 5-second 720p animation is about $0.98; 10 seconds about $1.94. Scenetra bills every model at provider cost with 0% markup, pay-per-generation.
Do I need to write a prompt?+
No — the prompt is optional, and the model can animate the image on its own. But a short motion-focused prompt is recommended: name the action, the camera move, and the atmosphere. Describe the motion, not the image — the model already sees your upload.
Does the animated video have sound?+
Yes, by default. Seedance 2 Fast generates synchronized audio — voice, sound effects, and background music — together with the picture, at no extra cost over the per-second rate. Toggle Generate Audio off for silent footage at the same price.
How is this different from the full Seedance 2 Image to Video?+
Same family, same first/last-frame workflow, but Fast is roughly 20% cheaper per second and quicker to generate, while the full Seedance 2 adds a 1080p output tier that Fast lacks. Draft your animations on Fast at 480p, then re-run keepers through Seedance 2 Image to Video when you need full HD.
