What is Seedance 2.0?

Seedance 2.0 is ByteDance's latest breakthrough video generative AI.

• supports four distinct modalities: text, images, video clips (up to 15 seconds) and audio (also up to 15 seconds).
• supports duration between 4 to 15 seconds long. When set duration = -1, Seedance 2.0 can automatically determine the optimal duration.

Price snapshot

Seedance 2.0 is available in two quality tiers on Atlas Cloud:

Compared to alternatives:

When to choose which:

• Veo 3.1 Lite: Budget-conscious projects, shorter clips.
• Wan-2.7: Video editing, with precise control over plots, camera shots
• Seedance 2.0: Video creating, with precise control over style/motion, audio synchronization, complex multimodal workflows

Seedance 2.0 Key Features

Enhanced Generation Quality

Seedance 2.0 delivers significantly improved base capabilities with more realistic physics, natural motion, and precise prompt following. The model handles complex actions and continuous movements with stability, producing smoother, more authentic video output.

Superior Consistency Control

Maintains character appearance, product details, typography, and scene consistency across frames. From facial features to clothing patterns, from packaging textures to font clarity—elements remain stable and accurate throughout the video without drift or degradation.

Cinematic Motion & Effects Replication

Accurately replicates sophisticated camera movements including dolly zooms, tracking shots, and mechanical arm multi-angle follows. Supports precise recreation of creative templates, complex transitions, and visual effects from reference footage without requiring professional terminology in prompts.

Seedance 2.0 Use Cases: Commercial, Social Media & Filmmaking

Commercial Use: Product Videos & Brand Content

Still to Stirring: Breathing Life into Stills Got a product shot or a character sketch that’s just... sitting there? Wake it up. Whether it’s the weave of a fabric or the curve of a logo, Seedance 2.0 holds onto those tiny details while adding the movement they deserve. It’s about keeping your brand’s soul intact while finally letting it move.

• Quick Specs:

  • Ref2Video: Up to 9 pics (30MB/each)
  • Image2Video: 2 pics max (30MB/each)

Social Media Use: Motion Cloning & Audio Sync

Steal the Scene: Motion Cloning Ever see a camera move you wish you could just... borrow? Toss in a reference clip. Seedance 2.0 doesn't just copy it; it digests the pans, tilts, and even the character's specific "vibe," then grafts that exact energy onto your fresh footage. It’s professional cinematography, minus the manual keyframing.

• The Nitty-Gritty:

  • Clips: Up to 3 files (50MB/each; 15s total)
  • Accepted: MP4, MOV

Pulse-Sync: Audio to Visuals Let the track call the shots. This isn't about random visuals; it’s about surgical precision. Drop in a voiceover or a bass-heavy beat, and the engine times every cut and camera zoom to the literal soul of the audio. It’s the fastest way to turn sound into a narrative that actually feels right.

• The Nitty-Gritty:

  • Audio: 3 files max (15MB cap; 15s combined)
  • Accepted: MP3, WAV

---

Filmmaking Use: Video Extension & Editing

Infinite Frames: The Time-Stretch Running out of footage is a nightmare. Now, you can just stretch time. Push your video forward or backward while keeping the characters, the lighting, and the "look" perfectly consistent. It’s the ultimate fix for when you need that scene to breathe just a few seconds longer.

• The Fine Print:

  • Input: 1 source video
  • Output: 4–15s of new, seamless footage

The Digital Swap-Out: Pixel-Level Control Total scene control without the reshoot. Need to swap an actor’s face, update a product's label on the fly, or delete a distracting object from the background? This tool does the heavy lifting while leaving your original camera work and lighting untouched.

• The Fine Print:

  • Source: The video you want to fix
  • Assets: Up to 9 reference images for the new look
