Before you use this model

The result is text, not video. Duration describes the intended video pacing and does not cap output tokens. Input and output tokens are charged separately. Text-only enhancement requires an explicit aspect ratio.

Specifications & defaults
Parameter Supported values / default
Resolution Not applicable
Target video pacing (text output) 4–15 seconds
Aspect ratio 21:9 · 16:9 · 4:3 · 1:1 · 3:4 · 9:16 · adaptive
Prompt limit 7000 Unicode code points
Definition defaults (subject to mode rules) duration: 5 · aspect_ratio: 16:9
Reference media limits 9 images / 3 videos / 3 audio clips

Media limits do not mean all inputs can be combined in every mode. Consult the full field reference for sizes, formats and incompatible combinations.

API INTEGRATION

Send HTTP requests from your server using the model and parameters you choose. ByteSOTA must first enable your account, API key and model permissions.

HTTP 202 means accepted. Save the task ID and follow next_poll_after_seconds. Generation status, result availability and billing status are separate facts.
