LTX-2 Retake
LTX-2 Retake regenerates targeted segments inside an existing clip. Define start time and duration. Replace video, audio or both with new prompts. Preserve surrounding motion and continuity. Ideal for selective revisions, dialog tweaks, and shot refinements without full regen.

"positivePrompt": "Replace the selected segment with a more dramatic continuation of the salt-flat motorcycle chase: one rider cuts sharply across the other leaving a sweeping ribbon of dust, the camera drops lower near the ground for a fast tracking angle, tires scatter crystalline grit, distant mountains shimmer in the heat haze, naturalistic cinematic motion, realistic sunlight, seamless match to the surrounding footage. Regenerate both sound and picture with roaring engines, skidding grit, rushing wind, and a brief tense near-collision feeling.",

"positivePrompt": "Retake only the selected segment so the rooftop performance suddenly shifts into a violent hailstorm. Keep the same violinist, wardrobe, camera angle, framing, rooftop layout, skyline placement, and motion continuity from the surrounding clip. Dark gust clouds roll in fast, loose sheets snap on a clothesline, hailstones ricochet across puddles and concrete, the musician braces against the wind while continuing to play with intense concentration. Cinematic realism, wet surfaces, sharp atmospheric detail, natural motion blur, believable continuity at the edit boundaries. Replace audio and video with fierce wind, rattling hail impacts, fluttering fabric, distant thunder, and a more forceful, urgent violin phrase that matches the performer’s movements.",

Shimmering crystals embedded in the cavern walls cast soft prismatic highlights across the platform. A few travelers in weathered expedition coats wait calmly with satchels and instrument cases. Fine dust motes drift in the air, subtle reflections ripple across the tram windows, and the arrival soundscape becomes a resonant metallic hum with echoing rail friction and distant cavern ambience. Keep camera movement, timing, and scene continuity natural with the surrounding clip.",
