Introduction
Seedance is ByteDance's flagship family of video generation models, built on the Volcengine platform. These models push the boundaries of AI-generated video with cinematic quality, synchronized audio generation, and multi-shot narrative capabilities that rival professional production tools.
Through ModelHunter.AI, you get unified access to the entire Seedance model family with a single API key — no need to manage separate Volcengine accounts or navigate Chinese-language documentation. This guide covers every variant, their strengths, pricing, and how to integrate them into your applications.
Model Family Overview
The Seedance family includes four tiers across eight model variants, each optimized for different quality, speed, and cost requirements.
| Model | Type | Resolution | Duration | Price/sec Range |
|---|---|---|---|---|
| 1.5 Pro | T2V + I2V | Up to 1080p | 4–12s (Auto) | $0.012–$0.116 |
| 1.0 Pro | T2V + I2V | Up to 1080p | 2–12s | $0.024–$0.122 |
| 1.0 Pro Fast | T2V + I2V | Up to 1080p | 2–12s | $0.010–$0.049 |
| 1.0 Lite | T2V + I2V | Up to 1080p | 2–12s | $0.017–$0.088 |
T2V = Text to Video, I2V = Image to Video. All models support multiple aspect ratios including 16:9, 9:16, 1:1, 4:3, 3:4, and 21:9.
Seedance 1.5 Pro
The flagship model with audio-visual generation and auto-duration intelligence. Price varies by resolution and audio.
Seedance 1.5 Pro is the latest and most capable model in the family. Its headline feature is synchronized audio generation — the model creates both video and matching sound in a single pass. A rainstorm scene comes with realistic rain sounds; a dialogue scene gets contextual ambient audio.
Auto Duration is another standout feature. Set duration to "Auto" and the model intelligently decides the optimal length (4–12 seconds) based on your prompt's complexity. A simple camera pan might get 4 seconds; a multi-action narrative could stretch to 12.
Both text-to-video and image-to-video modes are supported, with first-frame and last-frame control for I2V workflows.
