Select doubao-seedance-1-0-lite-i2v-250428 for this exact image-input edition. Supply the source image and describe subject movement, camera behaviour and the intended final view. Submission starts an asynchronous job; retain its ID and retrieve the completed video from that same job. - [**Ailoot Ultra · Video** `POST /v1/videos` `doubao-seedance-1-0-lite-i2v-250428`](https://ailoot.ai/models/en/doubao-seedance-1-0-lite-i2v-250428/#method-0) About the model This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below. Seedance 1.0 Lite Image-to-Video is the image-to-video selector doubao-seedance-1-0-lite-i2v-250428. Use it to animate a supplied scene, product view or character image. Describe what moves, how the motion develops and how the shot should finish. For a product scene, a practical brief might request a small object movement and a slow camera approach while preserving the arrangement visible in the source image. Use POST /v1/videos with model set to doubao-seedance-1-0-lite-i2v-250428 and a content array. Put the motion instruction in a text item, using type:text and text, and supply the image in an image\_url item with image\_url.url. The image URL must be accessible, or you can supply a data:image/\;base64,... representation. The documented image formats are jpeg, png, webp, bmp, tiff and gif. The image must be smaller than 30 MB, with width and height greater than 300 and less than 6000 pixels, and an aspect ratio greater than 0.4 and less than 2.5. Check the actual source file before submission. The model's image-input guidance uses ratio:adaptive. For image-reference generation, the documented resolution choices are 480p and 720p; 1080p is excluded for that mode. The duration field is an integer from 2 to 12 seconds, defaulting to 5. The documentation specifies 24 frames per second. Keep the scene simple enough for the requested duration: identify the opening pose, one main action and the final framing rather than asking the clip to carry an unrelated sequence of events. The configured request requires seed, camerafixed, watermark and execution\_expires\_after alongside model and content. seed ranges from -1 to 4294967295, with -1 documented as the default. watermark is a boolean, defaulting to false. execution\_expires\_after is measured in seconds from task creation, ranges from 3600 to 259200 and defaults to 172800. The documentation excludes fixed-camera control in image-reference mode; supply camerafixed:false for this profile. Synchronized audio generation is documented for a different Seedance edition and is not a control of this Lite image-to-video profile. Submission returns an Ailoot id before the video is ready. Keep that exact id and follow the returned polling\_url to check the same original job until its result is ready. The successful response contains a signed Ailoot link in content.video\_url after Ailoot has stored the completed file as an owned media asset. Save the video with the source image, prompt and settings, and review its appearance, movement and framing across the whole clip. Find the asset through GET /v1/media/assets?family=video, following every next\_cursor, and read GET /v1/media/assets/{asset\_id} with the actual asset\_id to obtain its content\_url. If a signed link returns link\_expired, read that same asset again for a refreshed content\_url. If the original task expires, fails or remains uncertain, preserve its response details and investigate it before creating another generation. **Ailoot Ultra · Video** `POST /v1/videos` `doubao-seedance-1-0-lite-i2v-250428` [`doubao-seedance-1-0-lite-i2v-250428`](https://ailoot.ai/models/en/#m=doubao-seedance-1-0-lite-i2v-250428&route=Ultra&caller=doubao-seedance-1-0-lite-i2v-250428&fmt=videos) ByteDance /`doubao-seedance-1-0-lite-i2v-250428` ### Overview Seedance 1.0 Lite Image-to-Video turns an image and motion instructions into a video.

The final charge is calculated from the cost recorded for the original generation. Measured output duration and forecast quantities are not the final billable quantity. Tariff references do not add request options. Supported parameters are listed for the selected method. Fast mode Not specified When fast mode is selected Flex mode Not specified When flex mode is selected Maximum reasoning effort Not specified When maximum reasoning effort uses the default adjustment #### Estimated rates for comparison #### Prices by configuration Match each charge to the conditions shown. Use one rate for each set of alternative configurations. | Configuration | Rate schedule | Forecast quantity | Billing unit | Charge | | --- | --- | --- | --- | --- | | ConfigurationBase token rates | Rate scheduleBase rate | Forecast quantity— | Billing unit— | Charge Input · Input tokens · Estimate for comparison only **—** / 1K tokens Output · Output tokens · Estimate for comparison only **—** / 1K tokens Input · Cache read · Estimate for comparison only **—** / 1K tokens Input · Cache write · Estimate for comparison only **—** / 1K tokens Input · Cache write, 1 hour · Estimate for comparison only **—** / 1K tokens | | ConfigurationOutput video tokens | Rate schedule— | Forecast quantity— | Billing unitper output video token | Charge Output · video output token · Estimate for comparison only **$0.000003** per output video token | | ConfigurationEstimated generation cost | Rate schedule— | Forecast quantityone generation estimate | Billing unit— | Charge Input · Estimated generation cost · Estimate for comparison only **$0.2112** estimate before generation This estimate is not an additional charge or a fixed rate for the completed generation. | Ailoot reserves an estimated amount before a request.
