Seedance (Text/picture generated video)

POST

/doubao/doubao-seedance

Interface Parameter Input Reference

Interface request parameters are generated with reference to the official documentation.

📌 Core Principle

Missing mandatory fields directly cause call failure; default values are enabled when optional fields are not configured. The priority of parameter instructions in content.text is higher than that of independent optional parameters.

Partial Parameter Description

generate_audio 「Audio Control」
🔍 Function: Controls whether the video contains synchronized audio (only supported by Seedance 1.5 Pro, invalid for other models)

true (default): Generate video with synchronized audio (automatically matches human voice/sound effects/background music; dialogues wrapped in double quotes for optimization)

false: Generate silent video

service_tier 「Service Tier」
🔍 Function: Specifies the task processing tier, unmodifiable after submission

default (default): Online inference with high timeliness and low quota

flex: Offline inference with higher quota, 50% of the online price, suitable for latency-tolerant scenarios

⚠️ Critical Notes

Priority: Parameters in content.text > independent optional parameters; avoid duplicate configuration.

For image-to-video generation, it is recommended to set ratio to adaptive to match the aspect ratio of the reference image.

Audio control (generate_audio) is only supported by Seedance 1.5 Pro; configuration is invalid for other models.

Generated files are retained for 7 days; task status can be actively checked via the task query interface.
