Features

lightricks/ltx-2-retake 🎬

LTX-2 Retake is a next-generation AI video refinement tool that empowers creators, editors, and studios to retake a specific segment of an existing video — without re-shooting or regenerating the full clip.

Rather than rebuilding a scene from scratch, Retake allows you to edit a localized section (2–16 seconds) while preserving the original footage around it, maintaining lighting, motion continuity, composition, and environment coherence.

🔧 Capabilities

• 🎬 Targeted Clip Editing — choose a time range in your video and regenerate only that portion.
• 🎤 Rewrite or replace dialogue while keeping speaker identity and tone.
• 🎥 Modify performance — adjust expressions, gestures, pacing, or emotional delivery.
• 📷 Change camera decisions — adjust pan/zoom, framing, or angle feel.
• 🎧 Refresh audio — update voiceovers, ambient layers, or background music.
• 🔄 Smooth transitions — Retake uses surrounding frames as context for seamless blending.

Perfect for rapid iteration cycles, creative variations, production feedback loops, and marketing experimentation.

📦 Input Parameters

Output resolution currently fixed at 1080p.

💰 Pricing

Pricing is determined based on the length of the edited segment. Longer replacement regions cost more, while very short adjustments are priced at a minimum threshold.

Example estimates:

🎯 Ideal Use Cases

• Reshoot alternatives without crew or scheduling
• Iterate on performance or emotional tone
• Create alternate ad or promo variations
• Correct timing or pacing issues
• Replace dialogue or audio environments
• Seamlessly integrate VFX timing adjustments

📌 Notes

• Best used when surrounding frames contain consistent motion/lighting
• Full output render time depends on edit complexity

✨ Why Retake?

Because high-quality revision shouldn’t require starting over.

Retake gives you surgical creative control — fast, flexible, and production-friendly.
