Provide an image URL to guide video styling. Omit for full AI creativity or add detailed images for specific vibes.
Set how long the video plays. Choose 5s for quick previews, 10s for more detailed scenes.
Allowed values:
Detail the animation vividly. E.g., A moonbase bustling with activity under a starlit sky as spacecrafts take off and land.
Set video sharpness. Use 720p for regular tasks; opt for 480p for quicker and lighter processing.
Allowed values:
Assign a seed for predictable outcomes. Choose any number from 1 to 999999 as a unique fingerprint for consistency.
min : 1,
max : 999999
Fix camera for stable framing, or unfixed for dynamic movements. Opt for dramatic scenes with unfixed options.
Choose video dimensions. Use 16:9 for landscape views; select 9:16 for tales on vertical screens.
Allowed values:
To keep track of your credit usage, you can inspect the response headers of each API call. The x-remaining-credits property will indicate the number of remaining credits in your account. Ensure you monitor this value to avoid any disruptions in your API usage.
Seedance 1.0 Pro Fast: Text-to-Video Generation Model
Edited by Segmind Team on October 25, 2025.
What is Seedance 1.0 Pro Fast?
Seedance 1.0 Pro Fast by ByteDance is a cutting-edge AI text-to-video model that turns text prompts or images into smooth, cinematic-quality videos with 3x the speed when compared to other regular models. It delivers visually stunning outputs that are coherent across multiple shots in terms of character, lighting, and scene logic, courtesy of its built-in multi-shot storytelling feature.
Key Features of Seedance 1.0 Pro Fast

FAQs
Q: How does Seedance maintain scene consistency? A: The advanced multi-shot technology used in Seedance 1.0 Pro Fast effectively maintains character, lighting, and scene coherence throughout the video sequence.
Q: What aspect ratios are supported? A: Seedance 1.0 Pro Fast supports multiple aspect ratios ranging from 16:9, 4:3, 1:1, 3:4, and 9:16, making it versatile for different platforms.
Q: Can I use reference images to guide the style? A: Yes, you can provide an image URL to control the visual style and simultaneously use AI's creativity during the generation process.
Q: What's the optimal workflow for rapid iteration? A: You can start with 5-second, 480p test generations to validate concepts; then scale up to 10-second, 720p for final outputs. Use seed values to maintain consistency across iterations.
Q: How does the camera_fixed parameter affect output? A: It maintains stable framing when you set the parameter to 'true'; while you will get video with dynamic camera movements when you set the parameter to 'false', making it ideal for more dramatic sequences.
