This workflow uses LTX 2.3 to generate smooth, cinematic videos from Start and End Frame. By providing two input images, one for the First Frame and another for the Last Frame, the system creates dynamic animations while maintaining strong visual consistency and realism.

LTX 2.3 analyzes image composition, subjects, lighting, and depth—or interprets the prompt to define the scene, atmosphere, and motion. It then generates coherent frame sequences with natural movement, including camera motion, environmental effects, and subtle subject animation.

How it works

  • Provide two input images, one for the First Frame and another for the Last Frame

  • Describe the desired scene, motion, or behavior

  • Run the workflow

  • LTX 2.3 produces a fully animated, high-quality video

Key Features

  • Image-guided and text-driven video generation

  • Smooth, cinematic motion and transitions

  • Prompt-controlled scene dynamics and animation

  • High visual consistency and temporal stability

  • Realistic lighting, atmosphere, and environmental effects

  • Minimal setup: just two images and a prompt

This workflow is ideal for creating cinematic visuals, storytelling scenes, realistic motion clips, and creative animations with minimal input.
