Seedance 2.0 AI Video Generator

ByteDance's multimodal video generation model — native audio, up to 9 reference images, start/end frame transitions, intelligent duration control, and cinematic output at 480p and 720p.

Seedance 2.0 by ByteDance is now available on NeonLights AI. This multimodal video generation model produces cinematic footage with native audio — dialogue, sound effects, and ambient sounds all synchronized with the visuals in a single generation pass.

Seedance 2.0 supports multimodal reference inputs (up to 9 images for character consistency and style guidance), start and end frame control for precise transitions, intelligent duration mode, and adaptive aspect ratios. It generates video at 480p or 720p resolution in durations from 5 to 15 seconds, with native audio generation enabled by default.

Key Features

🔊

Native Audio Generation

Audio and video are generated together — dialogue, sound effects, and ambient sounds are all synchronized with the visuals from the start. Put speech in double quotes in your prompt for matching lip movements and voice.

🖼️

Up to 9 Reference Images

Upload up to 9 reference images for character consistency, style guidance, and scene composition. Reference them in your prompt as [Image1], [Image2], etc.

🎬

Start & End Frame Control

Provide a starting frame to animate, or both start and end frames for controlled transitions. The model preserves the look and style of your input while adding natural motion.

🎥

Hyper-Realistic Motion & Physics

More realistic rendering of complex interactions — sports, dancing, object collisions, and multi-subject scenes with physically plausible motion.

⏱️

Flexible Duration & Resolution

Generate 5, 10, or 15-second videos at 480p or 720p resolution. Multiple aspect ratios including 9:16, 16:9, 4:3, 1:1, 3:4, and 21:9.

📝

Precise Prompt Following

Handles complex prompts with multiple subjects, specific actions, detailed camera movements, spatial relationships, and sequential actions with remarkable fidelity.

What's New in Seedance 2.0

Seedance 2.0 is a significant upgrade from Seedance 1.5 Pro, built on a unified multimodal architecture that accepts mixed inputs and produces coherent, audio-synced output.

Key improvements include multimodal reference inputs — combine up to 9 images in a single generation for character consistency, style guidance, and scene composition. Reference them in your prompt as [Image1], [Image2], etc.

Better motion and physics — more realistic rendering of complex interactions like sports, dancing, and object collisions. Intelligent duration — set duration to auto and let the model pick the best length for the content. Adaptive aspect ratio — let the model choose the best fit based on your inputs.

Text-to-Video

Describe a scene in natural language and get a video with matching audio. The model understands multi-subject interactions, camera movements, and emotional tone.

For dialogue, put speech in double quotes in your prompt — the model generates matching lip movements and voice. For example: *The man stopped and said: "Remember this moment."*

Be specific in your prompts — describe camera movements, lighting, mood, and specific actions for the best results.

Image-to-Video

Animate a still image by providing it as the start frame. You can also specify an end frame image to control where the video ends up. The model preserves the look and style of your input image while adding natural motion.

This is perfect for bringing concept art, photographs, and illustrations to life with realistic motion and synchronized audio.

Reference Images for Consistency

Upload up to 9 reference images for character consistency, style guidance, and scene composition. This is ideal for creating multi-shot narratives with consistent characters, outfit-change videos, and product showcases.

Note: Reference images cannot be used together with start/end frame images — choose one mode or the other for each generation.

The Evolution from Seedance 1.5

NeonLights AI also offers Seedance 1.5 Pro — the first generation of ByteDance's video model with dual-branch architecture that generates audio and video simultaneously.

Seedance 2.0 builds on that foundation with significant advances:

Multimodal reference inputs — Up to 9 reference images vs. single image input in 1.5.

Better motion and physics — More realistic complex interactions and multi-subject scenes.

Longer durations — Up to 15 seconds vs. 12 seconds in 1.5 Pro.

Intelligent duration — Let the model pick the optimal length automatically.

Seedance 1.5 Pro remains available on NeonLights AI at 60 credits — an excellent choice for quick audio-synced short-form video.

Tips for Best Results

Be specific in your prompts — describe camera movements, lighting, mood, and specific actions.

For dialogue, put the spoken words in double quotes: *The man stopped and said: "Remember this moment."*

When using reference images, label them in your prompt: *"The character from [Image1] walks through the garden from [Image2]."*

Start with shorter durations (5 seconds) and 480p while experimenting, then increase resolution and duration once you're happy with the style.
