We are excited to announce the immediate availability of LTX-2 Retake on RunDiffusion. This new capability transforms AI video generation from a slot machine into a true directorial tool, allowing you to refine, adjust, or reinterpret specific segments of a clip without losing the continuity of your original shot.
Don't Regenerate. Retake.
Traditional AI video workflows often require regenerating an entire clip to fix a minor issue, resulting in a completely new seed and loss of the original magic. LTX-2 Retake solves this by allowing you to define a specific start time and duration (2 to 16 seconds) to regenerate. The model then seamlessly blends your changes with the surrounding footage, preserving motion, lighting, and consistency.
True Directorial Control
Retake gives you the power to make high-level creative decisions after the footage exists:
- Performance Tweaks: Adjust an actor's expression or rephrase a line of dialogue while maintaining lip-sync.
- Camera Redirection: Change a static ending into a dramatic zoom or pan.
- A/B Testing: Create multiple variations of a product reveal or narrative ending from a single source clip.
Flexible Editing Modes
The tool offers three distinct modes to match your specific needs:
- Replace Video: Keep the original audio but change the visuals.
- Replace Audio: Keep the visuals but change the soundscape or dialogue.
- Replace Audio & Video: Completely reimagine the segment with synchronized sound and vision.
