Introducing LTX-2 Fast Text-to-Video on WaveSpeedAI: Create Stunning 1080p Videos with Synchronized Audio in Seconds

The future of video creation has arrived. WaveSpeedAI is thrilled to announce the availability of Lightricks LTX-2 Fast, a groundbreaking text-to-video model that transforms your written descriptions into professional-quality 1080p videos with perfectly synchronized audio—all in a matter of seconds.

Whether you’re a marketer racing to meet campaign deadlines, a content creator looking to scale production, or a filmmaker prototyping concepts, LTX-2 Fast delivers the speed and quality you need without compromise.

What is LTX-2 Fast?

LTX-2 Fast is part of Lightricks’ next-generation AI creative engine, specifically optimized for rapid, production-ready video generation. Unlike traditional text-to-video models that treat audio as an afterthought, LTX-2 Fast generates synchronized audio and video in a single unified pass—motion, dialogue, ambience, and music flow together naturally, eliminating the need for manual audio stitching or post-production synchronization.

Built on a sophisticated DiT (Diffusion-Transformer) hybrid architecture with space-time modeling, LTX-2 Fast represents a significant leap forward from earlier generation models. Lightricks, the company behind popular creative tools like Facetune and LTX Studio, designed this model to be the go-to solution for teams that need quick turnaround without sacrificing cinematic quality.

The “Fast” designation isn’t marketing speak—benchmark testing shows LTX models generating video up to 30-40x faster than comparable models on equivalent hardware, making it one of the most efficient text-to-video solutions available today.

Key Features

• Ultra-Fast Inference: Generate full-quality 1080p videos in seconds, not minutes. LTX-2 Fast is optimized for low latency and quick iteration, making it practical for real-world creative workflows where time is money.

• Native Audio-Video Synchronization: This is where LTX-2 Fast truly shines. Audio and video are generated together in one coherent process—motion changes naturally trigger audible accents, beats align with on-screen action, and ambient sounds match the visual environment. No more juggling separate audio tools.

• Up to 20 Seconds of Continuous Video: Generate extended clips that tell complete mini-stories, perfect for social media content, advertisements, and creative concepts that need room to breathe.

• Realistic Cinematic Motion: Handle complex camera movements including pans, dolly shots, zooms, and character movements with smooth transitions and natural lighting. The model understands cinematographic language and translates it faithfully.

• Style-Preserving Consistency: Maintain your intended color palette, tone, and artistic mood throughout the entire clip. What you envision in your prompt is what you get on screen.

• Production-Ready Quality: At 1080p resolution, outputs are immediately usable for most professional applications—from social media to client presentations to broadcast pre-visualization.
