What is Seedance 2 and how does it generate videos?

Seedance 2 is an AI video generator developed by ByteDance's Seed research team. It uses a diffusion transformer architecture to create videos from text or image inputs. The model understands natural language prompts and visual content to produce cinematic videos with realistic motion and physics-aware animation.

What types of videos can I create with Seedance 2?

Users can generate various video types including cinematic scenes, character animations, nature landscapes, product showcases, and dynamic action sequences. The tool supports both text-to-video and image-to-video modes, enabling creative applications across film pre-visualization, marketing, social media content, and educational materials.

How long does it take to generate a video with Seedance 2?

The average generation time is under 2 minutes per video. This speed is achieved through an optimized inference pipeline that maintains cinematic quality while allowing for rapid content creation. Users can generate multiple videos quickly during a single session.

What is the quality and resolution of Seedance 2 generated videos?

Seedance 2 produces videos with a maximum resolution of up to 1080p (high-definition) and a frame rate of up to 24fps. Output files are in MP4 format (H.264 codec), which provides universal compatibility for sharing, editing, and publishing across various platforms and devices.

Does Seedance 2 support audio generation?

Yes, the Seedance 2 Pro model includes integrated audio generation. It creates synchronized audio, sound effects, background music, and voice synthesis with multilingual lip-sync in a single generation pass. This eliminates the need for separate audio post-production work.

How does Seedance 2 compare to Sora, Kling, and Runway?

Seedance 2 distinguishes itself with best-in-class motion synthesis, built-in audio generation, and multilingual lip-sync. It offers superior character consistency and realistic physics simulation compared to competitors. Generation speed is also competitive, typically under 2 minutes, while providing a free tier and commercial licensing.

What is the difference between text-to-video and image-to-video?

Text-to-video generation uses descriptive natural language prompts to create videos from scratch. Image-to-video uploads a static image (PNG, JPG, JPEG, WEBP up to 50MB) and animates it with fluid motion while preserving the original visual style and composition. Both modes support cinematic camera control.

How much does it cost to use Seedance 2 Video Generator?

Seedance 2 offers a free tier with starting credits and no credit card required. Additional credits can be purchased, and pricing details are available on the website's pricing page. The cost per generation is listed as 8 credits, with free credits provided to new users to begin creating immediately.

Can I use Seedance 2 generated videos for commercial purposes?

Yes, all videos generated with Seedance 2 can be used for commercial purposes. The platform provides full licensing rights, allowing creators to incorporate the AI-generated content into monetized projects, advertisements, products, and other commercial ventures without restriction.

What is the maximum video duration Seedance 2 can generate?

Each generation produces videos with a duration of 5 to 10 seconds. The system includes an extension capability, allowing users to create longer sequences by chaining multiple generations together. This approach maintains quality while enabling more extended narrative content.

Does Seedance 2 maintain character consistency across frames?

Yes, Seedance 2 features an advanced character consistency module. This ensures that subjects retain their appearance, proportions, and detailing throughout the video. The technology supports coherent narrative sequences by preventing visual drift or inconsistencies between frames.

What input formats and aspect ratios does Seedance 2 support?

For text inputs, prompts can be up to 5000 characters. Image uploads accept PNG, JPG, JPEG, and WEBP formats with a maximum file size of 50MB. Supported aspect ratios are 16:9, 9:16, and 1:1, optimized for different platforms and display contexts including social media and presentations.

How do I get started with Seedance 2 for free?

To start, visit the Seedance 2 website and sign up for an account. New users receive free credits without needing a credit card. After signing in, select a creation mode (text or image), enter a prompt or upload an image, choose settings, and generate a video instantly with no setup required.

What languages are supported for multilingual lip-sync?

Seedance 2 Pro supports multilingual lip-sync for over 10 languages, including English, Chinese, Japanese, and Korean. This feature synchronizes generated audio with character mouth movements, making videos accessible to global audiences and reducing localization production needs.

What are the differences between Seedance 2 Standard and Pro models?

Seedance 2 Standard is optimized for fast text-to-video generation without audio. The Pro variant adds premium features including integrated audio synthesis, multilingual lip-sync, and potentially higher visual fidelity. Users select the model based on whether their project requires synchronized sound or prioritizes speed.

Can I access Seedance 2 via an API?

Yes, API access is available for developers. This allows integration of Seedance 2's video generation capabilities into custom applications, workflows, or platforms. Details on API implementation, rate limits, and authentication can be found in the developer documentation or by contacting support.

What file format are the generated videos exported in?

All generated videos are exported in MP4 format using the H.264 codec. This standard format ensures broad compatibility with video editors, social media platforms, presentation software, and playback devices. Users can download the file directly after generation for immediate use.
