Seedance 2.0 Fast Text To Video

Fast Seedance 2.0 text-to-video generation with controllable duration, aspect ratio, resolution, and optional synchronized audio.

Model Overview

Seedance 2.0 Fast Text To Video generates short video clips from text prompts. It supports 480p and 720p output, 4-15 second duration controls, flexible aspect ratios, and optional generated audio.

Best At

• Rapid text-to-video drafts and prompt iteration.
• Short clips with direct control over framing and duration.
• Social, storyboard, and concept-video variants where speed matters.

Limitations / Not Good At

• Auto duration can make cost harder to estimate before generation.
• Highly complex motion or long narrative continuity may need multiple attempts.
• Fast mode prioritizes turnaround over maximum final polish.

Ideal Use Cases

• Generating quick motion concepts from text briefs.
• Producing multiple short visual directions for review.
• Creating fast social or campaign video variations.

Input & Output Format

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

Performance Notes

• 720p costs more than 480p because pricing scales by generated video size and duration.
• Use explicit duration instead of auto when predictable cost is important.
