LTX Video 2.0 Fast | [image-to-video]

Lightricks' LTXV-13B delivers image-to-video generation at $0.04/second for 1080p through proprietary multiscale rendering that runs 30x faster than traditional diffusion models. Trading maximum resolution flexibility for speed and audio generation capabilities, it produces 6-20 second clips with synchronized sound at 25-50 FPS. Built for social media creators and rapid prototyping workflows where turnaround time matters more than 4K output.

Use Cases: Social Media Content | Marketing Previews | Rapid Creative Iteration


Performance

LTX Video 2.0 Fast prioritizes speed over resolution flexibility, delivering 1080p-2160p output with integrated audio generation at competitive rates compared to enterprise alternatives.

Built for Speed Without Sacrificing Quality

LTXV-13B uses multiscale rendering to generate video frames progressively rather than processing full resolution throughout the entire pipeline. This approach contrasts with standard latent diffusion models that maintain consistent computational load across all frames.

What this means for you:

  • Integrated Audio Synthesis: Generates synchronized sound effects and ambient audio directly from visual content without separate audio models or manual sync work

  • Flexible Duration Control: 6-20 second output range with frame rate options (25/50 FPS) adapts to platform requirements from Instagram Reels to YouTube Shorts

  • Resolution Scaling: Three quality tiers (1080p/1440p/2160p) let you balance output quality against generation cost per project budget

  • Single-Image Workflow: Transforms static images into motion sequences through prompt-guided animation, no multi-frame input or video editing required
