One-Shot Generation of Video and Audio

LTX-2 allows for simultaneous generation of high-quality video and audio, eliminating the need for separate dubbing or post-production. This feature ensures that dialogue, sound effects, and background music are perfectly aligned with video actions, significantly enhancing the workflow for content creators.

High Resolution and High Frame Rate

The model supports output up to 4096×2160 (4K) resolution and approximately 50 frames per second, making it suitable for both short films and commercial-grade content. The high-quality output means creators can use the generated content directly in professional editing without the need for additional processing.

Duration and Coherence

LTX-2 can generate continuous clips up to 20 seconds long while maintaining a consistent visual style across frames. This coherence reduces flicker and structural collapse, making it more suitable for narrative scenes and complex camera movements than other models that offer lower-quality animations.

Deep GPU Optimization

Designed for high-VRAM consumer NVIDIA GPUs, LTX-2 features deep optimization that enhances inference efficiency significantly. This allows for local generation of 4K video while reducing computational costs, which in turn minimizes reliance on cloud services and subscription models.

Multimodal Generation Modes

Seedance 2.0 supports three distinct input methods for maximum creative flexibility. Use Text-to-Video to create scenes from descriptive prompts, Image-to-Video to animate and extend a reference image while preserving its style, or Video-to-Video to restyle and modify existing footage. This allows you to choose the perfect starting point for any project, whether you're concepting from scratch or building upon existing assets.

Reference-First Workflow for Consistency

Move beyond vague text prompts. Seedance 2.0 prioritizes a reference-first approach, allowing you to upload images or video clips to anchor specific elements like character appearance, artistic style, color palette, and camera angle. This dramatically reduces guesswork and iterative prompting, ensuring higher consistency and more predictable, professional results aligned with your creative vision.

Integrated Audio-Video Synthesis

Generate synchronized audio alongside your video in a single pass. This feature includes background sound effects (SFX), musical scores, and even voiceovers with accurate lip-sync for over 10 languages, including English, Chinese, Japanese, and Korean. It eliminates the need for separate audio editing tools, streamlining the creation of complete, engaging video narratives.

High-Fidelity Output & Control

Produce professional-grade videos with resolutions up to 1080p, cinema-standard frame rates up to 24fps, and multiple aspect ratios (16:9, 9:16, 1:1) optimized for all platforms. With advanced control over duration, motion quality, and physics realism, Seedance 2.0 delivers best-in-class motion synthesis and character consistency for cinematic output that stands out.
