ComfyUI: Text-to-Video generation with LTX 2.3

ComfyUITry it →Watch full video →AIKnowledge2Go ·

Demo summary

The video demonstrates generating a 7-second video from a detailed text prompt describing a woman at a zoo, showing how the model handles specific dialogue and character actions.

Step-by-step

  1. Input a detailed prompt starting with shot size, setting, and lighting.
  2. Describe the character action and specific dialogue in the prompt.
  3. Specify the speaker and the tone of voice (e.g., 'excited genuine American tone').
  4. Increase the video length to 7 seconds to accommodate the dialogue length.
  5. Verify all LTX models are correctly selected in the workflow.
  6. Click Run to generate the video.

Options

  • Use simple prompts instead of elaborate descriptions.
  • Remove the structural labels (e.g., 'Response') from the prompt as they are optional.
  • Decrease resolution or video length if running out of VRAM.
  • Decrease Tiled Diffusion to 512 and Temporal Size to 2048 to fit on lower-end GPUs.

Watch out for

  • You must have ComfyUI, ComfyUI Manager, and all nodes updated to the latest version or errors are guaranteed.
  • You must clarify who is talking in the prompt to avoid a narrator-style voice-over.
  • Lowering Tiled Diffusion and Temporal Size settings will result in longer render times and slightly worse output quality.

Tips

  • Describe the shot and who is talking; the model will usually figure out the rest.
  • Ensure the video duration (seconds) is long enough to fit the amount of text being spoken.
