LTX2 VIDEO EXTENDWORKFLOW - WITH PERFECT AUDIO CLONING (COMFYUI)

The LTX2 Video Extend Workflow with Perfect Audio Cloning is a truly unique ComfyUI pipeline that allows you to extend existing video clips naturally and seamlessly—both visually and audibly. What makes this workflow exceptional is its ability to perfectly clone the original video’s voice, ensuring that newly generated dialogue sounds like a continuous extension of the source clip.

With this setup, you’re no longer limited by the original clip length. You can extend the scene, add new actions, or continue dialogue—all while maintaining consistent visuals, pacing, and voice identity.

How It Works:

1️⃣ Upload the original video you want to extend

2️⃣ Set the output width and height

3️⃣ Define how long you want to extend the video and audio (independently if needed)

4️⃣ Write a detailed prompt describing the new actions and dialogue

5️⃣ Click Queue—the workflow handles the rest

The result is a smoothly extended video with perfectly cloned audio that blends naturally with the original footage.
