Key Features
Discover what makes Seedance 2.0 Fast exceptional
~2x Faster Generation at Lower Cost
Seedance 2.0 Fast is the speed-optimized variant of the Seedance 2.0 family — roughly twice as fast as the Standard tier at about one-third lower credit cost per generation. Built for high-volume workloads and iterative prototyping where turnaround speed matters most.
Same Multimodal Reference Architecture
Keep the full multimodal input pipeline of Seedance 2.0: text prompts plus up to 9 reference images, 3 reference videos (15 seconds total), and 3 reference audio files. Mix and match freely to reference characters, scenes, camera moves, and sounds.
Native Synchronized Audio in a Single Pass
Dialogue with lip-sync, sound effects, ambient audio, and music co-generate with the video — no separate post-production dubbing. Put speech in double quotes in your prompt to drive on-screen dialogue automatically.
Flexible Formats for Every Platform
Generate 4–15 second clips at 480p or 720p across six aspect ratios — 16:9, 9:16, 1:1, 4:3, 3:4, and 21:9. Supports text-to-video, image-to-video, first-frame, and first-last-frame conditioning for precise motion endpoints.
Frequently Asked Questions
Everything you need to know about Seedance 2.0 Fast
Seedance 2.0 Fast is ByteDance's speed-optimized variant of Seedance 2.0. It shares the same multimodal architecture and capabilities — text-to-video, image-to-video, multimodal reference, video editing, and video extension — but trades some quality for significantly faster generation and lower cost.
Seedance 2.0 Fast is approximately 2x faster and about one-third cheaper per generation. It uses the same multimodal architecture but is optimized for speed and cost efficiency. Use the Standard tier when you want maximum output quality and the strongest director controls; use Fast when iteration speed and volume matter more.
Choose Fast for early prototyping, storyboard exploration, high-volume batch jobs, and budget-conscious workflows. Choose Standard for final production renders where cinematic quality, precise slow-motion, and complex multi-shot camera choreography are critical.
The same multimodal inputs as Seedance 2.0: text prompts, up to 9 reference images, up to 3 reference videos (≤15 seconds total), and up to 3 reference audio files (MP3). All input types can be combined in a single generation.
Seedance 2.0 Fast on Cuty.ai generates 4- to 15-second videos at 480p or 720p across six aspect ratios: 16:9, 9:16, 4:3, 3:4, 21:9, and 1:1. Start with 5-second clips while prototyping, then increase duration for final versions.
