Strengths

✓

Text-to-video

Seedance 2.0 generates video directly from a text prompt, producing 4-15 second clips with coherent motion and scene composition.

✓

Image-to-video

Animates a still image into motion, with first- and last-frame control to pin the start and end of the generated clip.

✓

Built-in audio

Optionally generates synced audio alongside the video, so a single request can return a clip with sound.

✓

4-15s duration

Supports clip durations from 4 to 15 seconds, giving more length than many competing generators in one pass.

✓

Flexible aspect ratios

Renders in a range of aspect ratios for landscape, portrait, and square outputs to fit any platform.

✓

First/last frame control

Lets you supply a first and/or last frame so the generated motion interpolates between defined keyframes for precise transitions.

Seedance 2.0 API: flexible AI video with built-in audio

Seedance 2.0 is ByteDance's high-quality video generation model, producing 4-15 second clips from text, images, video, or audio references. It stands out for built-in audio generation, flexible aspect ratios, and first/last-frame control for precise transitions.

Through YepAPI you generate Seedance 2.0 videos with one API key on the media queue endpoint, with token-based pricing that varies by resolution and duration — roughly $14/1M tokens at cost.

What is Seedance 2.0?

Seedance 2.0 is a video generation model from ByteDance (the Seed team). It creates clips of 4 to 15 seconds from a variety of inputs — text prompts, reference images, video, or audio — and can optionally generate synced audio alongside the visuals. It supports flexible aspect ratios for landscape, portrait, and square formats, plus first- and last-frame control so you can pin the exact start and end of a clip and let the model interpolate the motion between them. Seedance 2.0 is well suited to creators who want longer single-pass clips, multimodal conditioning, and sound, all from one model.

Build with Seedance 2.0 via YepAPI

Generate video by submitting a prompt — optionally with a reference image, first/last frame, or audio — to the YepAPI media queue using one API key. You poll the asynchronous job and download the finished clip when rendering completes, with audio baked in if you enabled it. The queue handles the GPU work, so your app just enqueues and collects results. The same key reaches every video model in the catalog, letting you mix Seedance with other generators in a single pipeline without re-authenticating.

Seedance 2.0 API pricing — Token-based, ~$14.0/1M tokens (varies by resolution and duration)

Seedance 2.0 uses token-based pricing that scales with resolution and clip duration, around $14.0 per 1M tokens at cost. Longer or higher-resolution clips consume more tokens, so a quick low-res test costs far less than a full 15-second high-res render with audio. You pay only for what you generate, and one YepAPI balance covers Seedance 2.0 alongside every other model on the platform.

Seedance 2.0 for longer clips with sound

Seedance 2.0 is the model to choose when you need more than a few seconds and want audio in the same pass — short narratives, music-driven clips, product demos, and social videos that benefit from synced sound. First/last-frame control makes it strong for precise transitions and looping content, while flexible aspect ratios let you target vertical feeds or widescreen alike. Image-to-video lets you animate existing key art into motion with sound attached.
