Seedance 2.0 Fast Image To Video

Fast Seedance 2.0 image-to-video generation from a start frame, with optional end-frame guidance and synchronized audio.

Model Overview

Seedance 2.0 Fast Image To Video animates a starting image into a short video clip. It supports optional final-frame guidance, 480p and 720p output, 4-15 second duration controls, aspect ratio selection, and optional generated audio.

Best At

• Quickly animating still images into short clips.
• Start-to-end frame transitions when both image inputs are provided.
• Fast visual iteration with controlled framing and duration.

Limitations / Not Good At

• Output quality depends on source image quality and prompt specificity.
• End-frame guidance works best when it is visually compatible with the start image.
• Fast mode prioritizes turnaround over maximum final polish.

Ideal Use Cases

• Animating product, character, or concept images.
• Producing quick motion tests from static art.
• Exploring end-frame transitions before a higher-quality pass.

Input & Output Format

• Input: required image_url and prompt; optional end_image_url, aspect_ratio, duration, resolution, generate_audio, and seed.
• Output: generated video URI returned on response.

Performance Notes

• Pricing scales with generated video size and duration.
• Use explicit duration instead of auto when predictable cost is important.
