Create Multi-Modal Cinematic Videos with Seedance AI
Seedance AI is a family of video generation models developed by ByteDance's Seed research team — the same company behind TikTok. The latest version, Seedance 2.0, launched in February 2026 and introduced a unified multimodal audio-video joint generation architecture. It is the first publicly available model to accept four input modalities simultaneously — text prompts, up to 9 reference images, up to 3 video clips, and up to 3 audio tracks — producing cinematic video with synchronized sound in a single generation pass.
What sets this model apart is the @ reference system, which lets creators tag specific elements in their prompt and bind them to uploaded references. Describe the camera movement you want from a reference clip, the character look from a photo, and the soundtrack vibe from an audio file — the model understands and combines them. The result is director-level creative control without complex prompting or post-production audio layering.
For creators who need consistent characters, multi-shot narrative sequences, and native lip-sync across multiple languages, Seedance 2.0 delivers a workflow that collapses what used to require separate tools for video, audio, and editing into one generation step. Access it on Vidofy.ai and start creating immediately.

Before You Generate: Seedance 2.0 Preflight Checks
Avoid failed generations and wasted time by verifying these model-specific settings
Verify Reference File Count and Format
Seedance 2.0 accepts up to 9 images (JPEG/PNG/WebP), 3 video clips (MP4/MOV, ≤15s total), and 3 audio files (WAV/MP3, ≤15s total). Exceeding these limits or using unsupported formats will cause generation failures.
Use @ Tags to Bind References in Your Prompt
The model's reference system requires you to tag elements (e.g., @character, @motion, @style) and bind each tag to a specific uploaded file. Without explicit bindings, the model may interpret references incorrectly or ignore them.
Select Aspect Ratio Before Generating
Choose from 16:9, 9:16, 4:3, 3:4, 21:9, or 1:1 before clicking generate. In image-to-video mode, the system auto-adapts to your input image aspect ratio — uploading a mismatched image can produce unwanted crops.
Specify Duration Intentionally
Clips range from 4 to 15 seconds. Longer durations with multiple reference files significantly increase generation time (up to 10 minutes). For rapid iteration, start with shorter 4–5 second clips before committing to full-length output.
Include Audio Direction in Your Prompt
Native audio is generated automatically, but specifying sound cues in your text prompt (e.g., 'calm ambient rain,' 'upbeat electronic music,' or 'character speaks softly in English') gives you far more control over the final audio layer.

Practical Tradeoffs: When Each Model Delivers More Value
Input Flexibility vs Output Resolution
Seedance 2.0's 12-file multimodal input pipeline gives it a clear edge for creators who work with existing assets — reference choreography from a dance video, lock a character look from a photo, and set the mood with an audio track, all in one generation. This makes it exceptionally suited for template-based production and content that repurposes existing creative material. Kling 3.0, on the other hand, pushes further on raw output quality with its 4K resolution tier and 60fps frame rate in Pro modes, making it a stronger choice when the deliverable needs broadcast-grade sharpness or will be displayed on large screens.
Storyboard Control vs Multimodal Reference
Kling 3.0's AI Director mode gives creators explicit shot-by-shot control — you can define up to 6 distinct camera angles, framings, and durations within a single 15-second clip. This structured approach excels for ad creatives and commercial content with precise visual requirements. Seedance 2.0 takes a different path: its strength lies in referencing motion, effects, and camera work from uploaded assets rather than describing them from scratch. If you already have footage or templates that capture the look you want, Seedance's reference workflow is faster and more intuitive.

Frequently Asked Questions
What input types does Seedance 2.0 accept?
Seedance 2.0 accepts four input modalities in a single generation: text prompts in natural language, up to 9 reference images (JPEG/PNG/WebP), up to 3 video clips (MP4/MOV, total duration ≤15s), and up to 3 audio files (WAV/MP3, total duration ≤15s). You can combine up to 12 files total across modalities.
What resolution and duration can I generate?
The model supports output up to 2K resolution (2048×1080 for landscape, 1080×2048 for portrait) on the Dreamina platform, though resolution availability varies by access platform — some API endpoints currently offer 480p and 720p. Durations range from 4 to 15 seconds per generation. Multiple aspect ratios are available: 16:9, 9:16, 4:3, 3:4, 21:9, and 1:1.
Does Seedance generate audio automatically?
Yes. Seedance 2.0 generates native audio alongside video in a single pass — including character dialogue with phoneme-level lip-sync, sound effects, ambient noise, and background music. You can also upload your own audio tracks to sync video content to specific beats or rhythms. The model supports lip-sync in 8+ languages.
How does the @ reference system work?
You tag elements in your text prompt using @ followed by a label (e.g., @dancer, @background_style, @motion), then bind each label to a specific uploaded file. This tells the model exactly how to use each reference — whether for character appearance, motion transfer, camera work, or audio influence. It works similarly to social media mentions and provides granular control over which input drives which aspect of the output.
Can I maintain character consistency across multiple shots?
Yes. Seedance 2.0 locks facial features, clothing, and visual style across frames and shots within a single generation. Upload a reference image to define a character once, and the model maintains that identity through scene changes and camera movements. For multi-clip projects, re-using the same reference image across separate generations helps maintain consistency, though some variation may occur between independent runs.
Can I use Seedance 2.0 output for commercial projects?
Commercial usage rights depend on the specific platform and subscription plan through which you access the model. Some platforms offer commercial licenses on paid tiers. Check the terms of service for your specific access platform — whether Dreamina, a third-party integration, or Vidofy.ai — to confirm commercial rights for your intended use case before publishing.
