ComfyUI: Extending AI video clips in LTX 2.3

Demo summary

The creator demonstrates the video extension feature within his workflow to break a complex 10-second shot into smaller, more manageable segments for the LTX model.

Step-by-step

  1. Open the LTX native video extension workflow
  2. Input the video frames from the previous generation
  3. Run the workflow to extend the clip

Options

  • Use first frame/last frame workflows to guide the generation to a specific destination

Tips

  • Use video frames as keyframe input to remind the model what characters and scenes look like
  • Break complex long shots into smaller, more manageable segments for the model
