LTX 2.3 Video Builder UI for ComfyUI - High Level Beta Overview
Video is here in case it hasn't fully loaded yet
Quick high-level overview of my Video Builder for ComfyUI, currently in beta testing.
This does not cover everything, since there are a lot of features, but it highlights some of the most important parts.
This started as a continuation of my earlier node-based music video workflows for ComfyUI. Now, the builder provides a full UI that runs those workflows in the background while adding many more tools for scene-by-scene video creation.
In the video, I quickly show:
- The main Video Builder UI
- The Wizard workflow
- Lyric mapping, transcription, and timing options
- Reference Builder
- Storyboard Builder
- Text-to-image options
- Video modes, including:
- Image-to-video
- Reference-to-video
- Ingredients-to-video
- Text-to-video
- LLM options for prompt creation
- Building and stitching a final video
Even though some parts are still named around music videos, the builder is not only for music videos.
It can also be used for:
- Short films
- Non-vocal videos
- Visualizers
- Story scenes
- Scene-based AI video projects
You can still almost fully automate a video inside the builder for a faster workflow, but the UI also gives you much more control for scene-by-scene editing.
You can let the system handle most of the process, or you can fine-tune individual scenes, prompts, references, timing, images, and video clips as much as you want.

Here is another video that goes over the FULL process of using the Reference to video (MSR loRa) in this UI. (New features were added after this video)

New features are added almost daily, so videos always become outdated :(
