LTX 2.3 prompt examples

Apr 2, 2026290

Read the full promptA surreal cinematic night scene in a quiet suburban street under a dark sky filled with soft stars and faint aurora-like light. A human figure slowly rises upward into the air above the houses in a calm, weightless motion, as if being gently lifted by an unseen force. From the body, powerful luminous rays and flowing beams of colored energy emerge upward into the sky, stretching above the figure in long radiant streams of turquoise, violet, gold, and soft green light. The ascent is slow and graceful, with the body slightly arched back and arms hanging naturally, while the beams continue to pour upward like spiritual light or cosmic fire. The houses and trees below remain dark and still, emphasizing the supernatural event in the sky. Dreamlike, mysterious, emotional, magical realism, slow levitation, glowing light trails, cinematic atmosphere, photorealistic, highly detailed, cinematic 4K.

Read the full promptA vintage weathered traffic light transformed into a floral installation on a quiet sunlit cobblestone street, each signal housing blooming flowers in warm orange, soft yellow, white, and pale pink tones. The camera remains completely static. The flowers and thin stems move only slightly in a gentle breeze, with soft natural swaying, tiny fluttering petals, and delicate leaf movement. The old metal pole stays still, the background remains calm and softly out of focus, and the whole scene feels peaceful, poetic, and warm with golden-hour light. Subtle natural motion only, no camera movement, photorealistic, highly detailed, cinematic 4K.

Read the full promptA cinematic first-person view of a person riding a vintage bicycle down a narrow country road through rolling green hills at golden sunset. The viewer sees both hands holding the handlebars and a fresh bouquet of wildflowers fixed to the front of the bike, with daisies, poppies, grasses, and small blue blossoms gently moving in the wind. The bicycle moves steadily forward along the winding road, creating a smooth immersive POV sensation. Meadows blur softly at the edges from motion, small countryside houses and distant mountains appear ahead, and the warm sun glows near the horizon under a dramatic pastel-orange and pink sky. Natural forward motion, subtle handlebar vibration, flowers lightly swaying, dreamy rural atmosphere, photorealistic, highly detailed, cinematic 4K.

Apr 2, 2026190

Read the full promptA cinematic underground parking garage scene with a young woman leaning against a graffiti-covered silver tuner car under cold greenish fluorescent lights. The camera smoothly slides to the right in a slow stylish lateral tracking shot, creating parallax between the girl, the car, the wet concrete floor, and the dark parked vehicles in the background. As the camera moves, the girl poses subtly for the camera with relaxed editorial attitude: a slight shift of posture, small change in head angle, calm change of gaze, and minimal body movement while staying leaned against the car. The car remains still, reflections glide across its metallic surface, and the whole atmosphere feels moody, urban, rebellious, and cinematic. Photorealistic, highly detailed, stylish street-fashion energy, cinematic 4K.

Apr 2, 202690

Read the full promptA cinematic surreal sunset scene with a lone person carefully balancing while walking along a tightrope suspended high above a quiet rural landscape. The figure moves slowly and cautiously, placing one foot in front of the other with precise delicate steps, arms slightly extended to maintain balance. Their posture stays controlled and focused, with subtle natural swaying of the body as they adjust to the tension of the rope. A long dark coat or dress moves gently in the wind, adding graceful motion. Below, trees, fields, and distant telephone lines fade into the evening landscape, while the sky glows with dramatic clouds in warm peach, pink, violet, and deep blue tones. The atmosphere feels dreamlike, poetic, and slightly unreal. Smooth realistic balancing motion, careful foot placement, soft wind, cinematic lighting, photorealistic, highly detailed, cinematic 4K.

Apr 2, 202640

Read the full promptA whimsical cinematic scene of a small frog wearing an oversized cozy gray knitted sweater, standing still in the middle of a dreamy wildflower meadow at soft misty sunrise. The frog remains in place and gently blinks its eyes with subtle natural movement, calm and curious. Around it, tall grass and delicate meadow flowers in pastel pink, cream, peach, and lavender tones sway softly in a light breeze, with gentle natural motion flowing through the field. In the background, a quiet winding river, distant trees, and soft morning fog create a peaceful storybook atmosphere. The camera slowly and smoothly moves around the frog in a graceful orbit, keeping the frog as the center of attention while revealing the meadow, flowers, mist, and warm early light from different angles. Dreamy, tender, magical realism, soft natural wind, photorealistic, highly detailed, cinematic 4K.

Apr 2, 2026240

Read the full promptA cinematic rainy night street scene with a couple in love standing close together under heavy rain on a neon-lit city corner, holding each other's hands tightly as if they have just run to one another from opposite ends of the street. Their bodies are still slightly tense from the rush, shoulders rising and falling with visible breathlessness, chests moving as they catch their breath, damp hair clinging to their faces, clothes soaked through by the rain. They stay close, emotional and intimate, looking at each other with a mix of relief, longing, and urgency. Rain pours hard around them, water splashes on the pavement, neon reflections shimmer across the wet street, and the atmosphere feels romantic, dramatic, and electric. Subtle realistic breathing, slight trembling from exertion, hands held firmly, cinematic lighting, photorealistic, highly detailed, emotional realism, cinematic 4K.

Apr 2, 2026200

Read the full promptA cinematic close-up of a small cat gently swimming in clear sunlit water, with only its head, neck, and part of its back visible above the surface. The cat calmly paddles forward, creating soft ripples and delicate shimmering reflections around its body. It naturally blinks its eyes, gently twitches its ears, and looks around from side to side with curious, alert little head movements. Its wet fur clings softly to the face and neck, whiskers catch the light, and tiny droplets sparkle on the surface. The water moves beautifully with subtle waves, glowing highlights, and soft underwater patterns. Peaceful, adorable, realistic animal behavior, warm natural light, photorealistic, highly detailed, cinematic 4K.
