Seedance 2.0 Fast is an AI video generator launched by ByteDance. Official materials describe it as ByteDance's most advanced video AI model, released in February 2026, aimed at production-grade workflows from creative ideation to broadcast-ready finished films.
Main capabilities
- Text-to-video: Input detailed story prompts to automatically assemble coherent multi-shot sequences while maintaining character and style consistency across different shots.
- Image-to-video: Upload reference photos to preserve subject identity during animation, combined with physics-aware motion and natural camera movement.
- Native audio: Can simultaneously generate synchronized dialogue, ambient sound, and sound effects. The official description says it has accurate lip sync, with no need for manual audio post-editing.
- Multi-shot automation: The official description calls it the industry's first video AI to automatically orchestrate coherent scene sequences, maintaining character identity and visual style across different camera angles.
- AI video editing: Natural language instructions can be used to modify specific elements in a video, such as "replace the red car with a vintage truck," while preserving lighting and physics.
- Director-level control: Multi-reference fusion, allowing simultaneous input of face photos, motion video, and audio beats for four-modal fusion.
- Auxiliary tools: Can be used to quickly prepare materials, such as removing backgrounds, upscaling assets, or retouching reference images before sending them into video generation.
Technical features
- Physics engine realism: The official description says the newly trained physics module can render fluid dynamics, cloth movement, and gravity without deformation artifacts.
- Professional 1080p output: Can export native 1080p resolution and provides full commercial licensing for broadcast, advertising, and high-end distribution.
- Speed: The official description says generating a broadcast-ready 10-second clip takes less than 2 minutes, faster than competing models, and speeds up professional workflows by about 30%.
- Four-modal control: The official description says it can simultaneously process text, up to 5 images, motion video, and 3 audio clips, and says its fusion capability exceeds Sora 2 or Veo 3.1 (the above comparisons are official claims).
How to use
- Input a story prompt or reference materials, and use up to 5 images and 3 audio clips for multimodal control.
- The AI automatically orchestrates multi-shot sequences, maintaining character consistency, visual style, and audio synchronization across scene transitions and camera changes.
- Preview and export a finished film at professional resolution, with native audio. The official description says it can be used directly for commercial purposes without post-production.
Subscription and credits The official page mentions subscription plans, which can be canceled or changed at any time. Tiers include: Standard (standard generation queue, batch generation each time 2-4 outputs, high-quality mode, community support, commercial license and unrestricted usage rights), Starter (includes everything in Standard, plus a priority generation queue and priority email support), and higher tiers (including everything in the previous two, plus unlimited models and a faster generation queue). One-time credit packs are also available: 100, 300, and 800 credits; credits never expire. Specific pricing is not given on the page.
Use cases
- Short films, advertising, and broadcast content creation that require multi-shot coherent storytelling and character consistency.
- Video projects that need native synchronized dialogue, ambient sound, and sound effects, and want to reduce audio post-production.
- Scenarios that require image-to-video to preserve the identity of a specific person or subject.
- Editing tasks that require quickly modifying video elements with natural language instructions.
