Short answer: Image to video AI turns a still into a short moving clip. On Seedance 2.5 you upload one image, set duration and aspect ratio, then generate at up to 1080p for 4–30 seconds — useful when a photo already defines the subject.
Open the Seedance 2.5 generator, choose Image to Video, and keep the first brief to one subject plus one camera move. New accounts receive free credits on sign-up, enough for one video; confirm the estimate for duration and resolution before submitting.

What is image to video AI?
Image to video AI starts from a still and invents motion, camera movement and temporal continuity around that frame. The photo carries identity, product look or composition; the prompt steers what should move and what should stay stable.
It is a stronger fit than text-only generation when you already have an approved product shot, character keyframe or location still. It is a weaker fit when the brief needs a scene that does not exist in any image yet — then start in Text to Video instead.
For the full create-and-review sequence after the first export, follow the Seedance 2.5 tutorial. This page stays on the decision and setup: how to turn an image into video without fighting the still.
Which inputs matter most for Seedance 2.5 image to video?
Three controls do most of the work: the input image, duration, and aspect ratio. Resolution is chosen among 480p, 720p and 1080p — 1080p is the maximum on Seedance 2.5. Duration runs from 4 to 30 seconds per generation.
| Control | What to set | Why it matters |
|---|---|---|
| Input image | One clear still with readable subject and clean edges | Identity and composition start from the photo |
| Duration | 4–30 seconds | Short continuous moves are easier to judge on a first test |
| Aspect ratio | 16:9, 9:16, 1:1, 4:3, 3:4 or 21:9 | Mismatched ratio crops or letterboxes the still’s intent |
Pick ratio to match the still’s framing before polishing adjectives. A vertical product photo forced into 21:9 will lose the composition you already approved.
How do you turn an image into video on Seedance 2.5?
In the Seedance 2.5 workspace, select Image to Video (or open the dedicated Image to Video entry), upload one still, set ratio and a duration between 4 and 30 seconds, then choose 480p, 720p or 1080p. Write one clear motion instruction and name what must stay locked — face, label, logo or product outline.
New accounts receive free credits on sign-up, enough for one video. Use that clip to answer a single question — for example, whether a slow push keeps the label readable — rather than testing every style at once.
Illustrative brief (not a measured result): a product bottle on a desk, soft daylight from the left, camera drifting gently forward, bottle outline and label text staying sharp. Export, then compare silhouette and type against the still before changing more than one variable.
What should you check after the first image-to-video export?
Play the file next to the source still. Confirm identity held, the requested move happened, and empty edges or warping did not appear around the subject. If the face or product drifts, tighten the lock instruction or shorten the move before regenerating.
If the frame feels sparse or cropped wrong, revisit aspect ratio against the still rather than stacking more style words. When you continue past the signup allowance, compare plans and packs on the pricing page. Read billing period and checkout total together; the first free clip does not define ongoing commercial terms.
| Review signal | Likely fix | Avoid |
|---|---|---|
| Subject identity drifts | Stronger lock on face/product; shorter move | Adding unrelated style adjectives |
| Wrong crop vs still | Match ratio to the photo | Forcing ultrawide on a vertical still |
| Motion too chaotic | One camera verb; reduce competing actions | Multiple moves in one short take |
| Detail soft at distance | Closer framing or 1080p if estimate allows | Assuming every still needs maximum length |
What are the common questions about image to video AI?
Can Seedance 2.5 turn an image into video?
Yes. Use Image to Video with a single clear still, then set duration, ratio and resolution before you generate.
What is the maximum resolution?
Seedance 2.5 outputs 480p, 720p or 1080p. 1080p is the highest option on this model.
How long can an image-to-video clip be?
Duration can range from 4 to 30 seconds. A shorter continuous move is usually easier to evaluate on a first test.
Which aspect ratios are available?
16:9, 9:16, 1:1, 4:3, 3:4 and 21:9. Choose the ratio that matches the still’s intended delivery.
Can I try image to video for free?
New accounts receive free credits on sign-up, enough for one video. Check whether your chosen duration and resolution fit the estimate before generating.
Where should you create your next image-to-video clip?
Open Seedance 2.5, upload one approved still, set ratio and a short duration, and review identity against the photo before you scale the brief.
