This is not just a standard fine-tune; it is a fundamental restructuring of the LTX-Video (2.3) generation logic.

I am thrilled to present the official release of LTX2.3 Singularity to the community. This comprehensive optimization framework focuses heavily on Image-to-Video (I2V), First & Last Frame Control, and Reference-to-Video generation. Although it has currently undergone only nearly 100,000 steps (calculated by gradient accumulation), its enhancements in physical consistency, dynamic motion, and cinematic expression have already far exceeded expectations.

Prompt:8-second video, one-take shot,this high-octane cinematic animation features a young woman skateboarding down a steep coastal road during a bright, sunny afternoon, evoking a sense of freedom and adrenaline. From 0 to 3 seconds, the girl crouches low on her skateboard, her long brown hair streaming behind her as she accelerates down the incline. Between 4 and 8 seconds, she maintains a steady, aerodynamic posture, skillfully navigating the winding asphalt while her oversized white t-shirt billows in the wind, showing intense focus and excitement. The camera utilizes a low-angle tracking shot from directly behind the skater, moving at a high velocity to create an immersive sense of speed; the composition starts with a wide-angle view of the sprawling coastal city and ocean, then maintains a medium-close-up on the girl's back and the board throughout the descent. The setting is a picturesque Mediterranean-style hillside overlooking a turquoise bay under a vibrant blue sky filled with fluffy white clouds, featuring high-contrast sunlight casting sharp shadows and a warm, high-saturation color palette. The soundscape is dominated by the continuous, high-pitched whirring of skateboard wheels against the pavement and the rushing sound of wind, synchronized with an upbeat, rhythmic electronic background track. Significant motion blur is applied to the road surface and passing scenery to enhance the perception of speed, combined with a sharp focus on the central subject to maintain a polished, professional look，无字幕。 Prompt:Modern anime style, office setting, weary and playful mood. 0-3s, a young man with messy black hair and sharp features wearing a black button-down shirt yawns deeply, eyes closed in exhaustion. 3-6s, he sighs and covers his face with both hands, rubbing his temples and eyes with a look of intense fatigue. 6-9s, he lowers his hands, looking startled as a female hand rests on his shoulder; he turns his head slightly with wide, tired eyes. 9-12s, a beautiful woman with long black hair and glowing red eyes leans in close to him, wearing a professional suit and a playful, mischievous smile. 12-15s, the man stares back at her with a heavy-lidded, slightly annoyed gaze, while she continues to smile at him. 0-8s, medium shot, eye-level, static camera focused on the man at his desk. 8-15s, dolly in to a tight close-up, focusing on the interaction between the two characters, shallow depth of field blurring the background.
