LTX 2.3 prompt examples

Apr 2, 2026460

Read the full promptA majestic dark silver-gray unicorn stands still on a rocky mountain peak at sunset, surrounded by dramatic distant mountains and a glowing sky filled with warm gold, peach, and dusky blue tones. The camera remains completely static. The unicorn gently blinks and slowly looks around from side to side with calm, noble, natural head movement, as if quietly observing the vast landscape. Its long flowing mane and tail stream continuously in the wind, moving softly and elegantly with layered strands catching the fading light. A faint mist drifts around the rocks near its hooves, and the horn glows subtly against the sky. The overall mood is magical, serene, and powerful, with realistic animal motion, graceful wind-blown hair movement, photorealistic, highly detailed, cinematic 4K.

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.

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, 2026380

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, 20264450

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.

Read the full promptA glossy orange plastic fox figurine with simple rounded shapes sits on a smooth electric-blue backdrop, close-up. The fox slowly lowers its head in one gentle nod and lifts it back to the start. A white plastic pedestal under its feet echoes the white tip of its tail. Soft light from a large softbox on the left, a clean highlight on the glossy orange. The camera stays still. No text, no logos, no watermark.

Oct 5, 2026160

Read the full promptA businesswoman in a white blazer walks at an even pace along a glass-walled office gallery, seen in a medium side shot. Sage-green panels line one side, an ochre wooden floor runs beneath her, white walls fill the far end. Daylight pours down from a skylight above her head and lays soft bright bands across the floor. The camera tracks smoothly alongside at her pace, nothing else moves. No text, no logos, no watermark.

Oct 20, 202640

Read the full promptA stylized 3D animated hedgehog with big glossy expressive eyes, a round soft body and rounded cream quills, wearing a chunky sage-green scarf. Close-up of the hedgehog walking along a curving autumn path covered in pumpkin-orange leaves, with a cream stone wall and rounded sage-green bushes behind it. It takes a few steps forward, then turns its head and looks back over its shoulder with a warm, curious smile. Soft bright light as in a 3D animated film: a low warm sun from the left as the key, gentle violet shadows under the hedgehog and across the path. The camera slowly pushes in. Simple large shapes, soft matte materials, background gently out of focus. No text, no logos, no watermark.
