Submit the request with `VIDGO_API_KEY`. A `task_id` is returned immediately. Keep it until the task reaches `finished` or `failed`. 2. Use [Query Task Status](/api-manual/task-management/status) to retrieve the result. If you provide a `callback_url`, Vidgo sends the result to your [webhook](/api-manual/task-management/webhooks) when the task finishes or fails. # Seedance 1.0 Pro Text to Video Create five- or ten-second video scenes from written descriptions with Seedance 1.0 Pro, with output up to 1080p. ## Available Models * **bytedance/seedance/v1/pro/text-to-video** - Generate video scenes from text prompts. ## Duration Options * **5, 10 seconds** - Set `duration` as a numeric integer. Optional. Default: **5 seconds**, only when omitted. Strings, booleans, null and fractional values are rejected. A numeric value such as `5.0` is equivalent to `5`. ## Key Features * Generate video scenes from text prompts. * Choose from `720p`, `1080p` output resolutions. ## Advanced Parameters Set `model` and optional `callback_url` at the request root. Place all workflow parameters, including output options, inside `input`. Send only the input fields supported by this workflow. Unsupported `input` fields are rejected before credits are deducted. Input URLs must use HTTP(S), include a hostname, and contain no embedded credentials or whitespace. Defaults apply only when optional input fields are omitted; explicit null and empty values are rejected. ### Prompt * `prompt`: Required string. Describe the scene and desired motion. After trimming surrounding whitespace, length must be **1-10,000 Unicode characters**. Non-string values are rejected. * The value must not be blank when supplied. ### Resolution * `resolution`: Optional. Accepted values: `720p`, `1080p`. Default: `720p`, only when omitted. Aliases, different casing, surrounding whitespace and numeric values are rejected. ## Pricing Both workflows use the same price per generation (\$0.005 per credit): | Resolution | Duration | Credits | USD | | ---------- | ---------- | ------- | ------- | | 720p | 5 seconds | 21 | \$0.105 | | 720p | 10 seconds | 42 | \$0.210 | | 1080p | 5 seconds | 43 | \$0.215 | | 1080p | 10 seconds | 86 | \$0.430 | Credits are deducted on submission and refunded if the task fails. ## OpenAPI ````yaml api-manual/video-series/bytedance-seedance-v1-pro-text-to-video.json POST /api/generate/submit openapi: 3.0.0 info: title: Vidgo API - Seedance 1.0 Pro Text to Video description: >- Create five- or ten-second video scenes from written descriptions with Seedance 1.0 Pro, with output up to 1080p. version: 1.0.0 servers: - url: https://api.vidgo.ai security: - BearerAuth: [] paths: /api/generate/submit: post: tags: - Video Series summary: Seedance 1.0 Pro Text to Video description: >- Use the documented input types and values.
