LTX Director: set up LTX 2.3 video workflows in ComfyUI

This tutorial explains how to use LTX Director, a timeline editor for LTX 2.3 video generation in ComfyUI. The source describes it as a free, open source tool for creating videos locally. Installation starts in ComfyUI Manager: search for What Dreams Cost, select the nightly version, and update the ComfyUI LTX video nodes and KJ nodes. Two example workflows provide the same functionality, with either compact subgraphs or an expanded node layout.

The examples cover image-to-video generation, timed text segments through prompt relay, and guide images placed as keyframes anywhere on the timeline. The presenter moves an explosion image later in a shot, then prompts the action that should precede it. Guide strength controls how strongly an image influences generation.

Custom audio can drive a scene alongside images and timed actions. The presenter recommends more specific lip-sync prompts and adding the spoken words when audio is unclear. Text-to-video uses text segments with custom output dimensions; a global prompt applies persistent conditions across the whole video.

The presenter cautions that complex actions need detailed prompts and enough segment time. Their 12 GB RTX 3060 requires a lower-quality model version and lower resolution for these examples; this is their reported setup, not a stated minimum requirement.
