LTX Director Multi in ComfyUI

Use case: make longer AI video sequences with more consistent characters by splitting a story into keyframed segments, then chaining multiple LTX Director workflows.

1. Core idea

LTX Director Multi combines prompt-relay scene control with keyframe-guided video generation. Instead of trying to generate one very long clip in a single pass, build separate, connected video segments.

Why split it? Long generations can overload GPU memory and cause slowdowns or crashes. Shorter linked segments are easier to manage and can still feel continuous.

2. Story and keyframe setup

Scene plan

Break the story into scenes.
The video example uses 10 scenes for Little Red Riding Hood.
Create a starting image/keyframe for each scene.

Consistency trick

Reference the same original character image when creating scene frames.
Keyframes can be made with GPT, Gemini, or Flux Edit.
Use multiple keyframes to keep the character stable across scenes.

3. Practical ComfyUI workflow

Create scene prompts with this simple structure: Environment → Action → Camera Movement → Dialogue.
Drag the first five scene images into the first LTX Editor node.
Place images about 6 seconds apart on the timeline.
Add each scene prompt.
At the end of segment 1, add an extra frame from scene 6 so segment 2 connects smoothly.
Drag the remaining five scene images into a second LTX Editor node and repeat.
Chain more LTX Editor nodes for longer projects.

4. Optimization tips from the video

Keep prompts simple and straightforward.
Use a cinematic global prompt to maintain lighting, atmosphere, and visual style.
Use a GGUF model for lower-end hardware.
Add transition LoRAs for smoother scene changes.
Add a detail-enhancing LoRA for sharper visuals.
Insert a VRAM cleanup node after each generation to reduce memory overload risk.
