The page follows the same API-first structure as the reference: test the model, understand the fields, then move into integration.
Text and image to video
Generate videos from prompts alone, or add up to two image URLs to guide composition, subject identity, and scene style.
Optional audio generation
Enable generated audio when the clip needs synchronized atmosphere, effects, or voice-driven storytelling.
Flexible output settings
Control aspect ratio, resolution, duration, and camera locking so the API output fits product, ad, and social formats.
Narrative-ready motion
Use dynamic camera movement for cinematic scenes, or fixed lens mode when a stable product or character shot matters more.
From playground test to production request
A compact integration path for teams that want to validate Seedance 1.5 output before connecting the API to an app.
1. Prepare request
Add a prompt, choose whether to include image URLs, then set aspect ratio, resolution, duration, and audio behavior.
2. Submit generation
Call the API with your account key and the bytedance/seedance-1.5-pro model payload.
3. Poll and render
Track the task until it succeeds, then retrieve the generated video URL for your app, campaign, or pipeline.
What you can create with Seedance 1.5 API
Use the API when your workflow needs repeatable short-form video output with practical controls.
Built for real API workflows
Account-gated execution
Users sign in, submit jobs, and consume credits through the existing SdanceAI generation flow.
Reference image handling
The API accepts uploaded or hosted image URLs for image-to-video workflows, with previews and payload editing in the studio.
Cost-aware settings
Resolution, duration, and audio options can be selected together to balance output quality, speed, and credit cost.
Seedance 1.5 API questions
What is Seedance 1.5 API best for?
It is best for short-form AI video generation where teams need prompt control, optional image guidance, and optional synchronized audio in a repeatable API workflow.
Does Seedance 1.5 API support image-to-video?
Yes. The request can include image URLs for image-to-video generation, or omit them for text-to-video generation.
Can I generate audio with Seedance 1.5 API?
Yes. The payload includes a generate_audio option. Enabling audio can increase generation cost, so review pricing before production use.
Which aspect ratios are supported?
The current request schema supports common formats such as 1:1, 4:3, 3:4, 16:9, 9:16, and 21:9.
What duration and resolution options are available?
The API supports short video durations with 480p, 720p, and 1080p resolution options. Pick them together based on your target channel and cost expectations.
What does fixed_lens do?
fixed_lens locks the camera for more stable, static shots. Leave it disabled when you want Seedance to add dynamic camera movement.
Where can I test it before integrating?
Use the playground on this page to test prompt, image URLs, aspect ratio, duration, resolution, audio, and API payload behavior before moving into production.
Can I use Seedance 1.5 API for commercial projects?
This page is configured for production-style API workflows. For commercial use, review your account plan, credit balance, model availability, and applicable content policy requirements.
