LTXV 2 Fast Image-to-Video

LTXV 2 Fast API Overview

LTXV 2 Fast Image-to-Video is the latest iteration in the LTXV series, AI models engineered for high-fidelity, controllable video synthesis. Designed for creators, developers, and studios, LTXV 2 Fast delivers ultra-realistic short-form videos in seconds, leveraging either a textual prompt or a single input image. Built for speed without compromising visual coherence, this model supports resolutions up to 4K, making it ideal for rapid prototyping, social content, and dynamic media creation.

Technical Specifications

• Model Type: Denoising Diffusion Transformer
• Input Modalities: Image + optional prompt
• Frame Rate: 24–50 FPS

Performance Benchmarks

• Native 4K video generation with crisp textures and clean motion
• Multi-scene and multi-keyframe workflows for longer videos with consistent style and motion
• Up to 50% lower computational cost compared to similar video generation models

Key Features

• High-Fidelity  Generation: Creates synchronized, coherent videos with natural motion and audio from single images or text prompts
• Fast Generation: Optimized pipelines and diffusion transformer architecture enable very rapid video synthesis for short clips
• Creative Control: Advanced conditioning with multi-keyframe inputs  for frame-level precision and style consistency

LTXV 2 API Pricing

• 1080p: $0.042 / sec
• 1440p: $0.084 / sec
• 2160p (4K): $0.168 / sec

Comparison with Other Models

vs Runway Gen-2: Runway Gen-2 offers strong text-to-video output but lacks native 4K support and is slower for image conditioning. LTXV 2 Fast provides higher resolution, faster inference, and more precise image-to-video alignment.

vs Pika 1.0: Pika excels in stylized or anime-like outputs but struggles with photorealism at scale. LTXV 2 Fast prioritizes realism, supports 4K, and delivers more consistent physics-based motion.

vs Luma Ray 2: While Luma Ray 2 excels in real-time storytelling and consistent scene transitions for lower-res videos, LTXV provides superior visual fidelity and multi-modal input support.
